Customizing Asus AM200g - III. jabberd and vim

17.6.2008 23:04 | Přečteno: 2745× | Linux | poslední úprava: 3.7.2008 01:49

It took me some time to actually make the jabber server working, few people seem to really care about cross-compiling their stuff, but I succeeded and here's the howto:

0. Errata

First of all, during the testing I found out I have to modify the environment settings - the static build of jabber did not work at all. I also added the location of newly compiled libs and headers so that they can be used by programs that depend on them. Some programs were in C++, so the CXX variable had to be set as well. Here's the final environment (P.S. in the end it seems some additions like CPPFLAGS would be needed for perfection, but I'm not in the mood of retrying):

$ cat environment
TOOLCHAINS_HOME=/opt/toolchains/uclibc-crosstools

export LIBS="-L${TOOLCHAINS_HOME}/lib/gcc/mips-linux/3.4.2 \
        -L/var/usb/usb_1/lib \
        "
export INCLUDES="-I${TOOLCHAINS_HOME}/include/c++/3.4.2 \
        -I${TOOLCHAINS_HOME}/mips-linux/sys-include \
        -I/var/usb/usb_1/include \
        -I/home/hajma/Documents/GPL_AM604G_ForRussia/GENERIC_6348_WLAN_A34_3-06-02-01/kernel/linux/include \
        -I/var/usb/usb_1/include/ncurses \
        "
#export CFLAGS="${INCLUDES} ${LIBS} -static"
#export LDFLAGS="-static"
export CFLAGS="${INCLUDES} ${LIBS}"
export LDFLAGS=""
export CC="${TOOLCHAINS_HOME}/bin/mipsel-uclibc-gcc"
export CXX="${TOOLCHAINS_HOME}/bin/mipsel-uclibc-g++"

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${TOOLCHAINS_HOME}/lib
export PATH="${TOOLCHAINS_HOME}/bin:${PATH}"

Let's use it:

. environment

Also the symlinking of the uclibc toolchain needed to be further enhanced for some package to get built:

# cd /opt/toolchains/uclibc-crosstools/bin
# for A in mips-linux-uclibc-* ; do
> ln -s ${A} mipsel-linux-${A#mips-linux-uclibc-}
> done

1a. jabberd

$ cd GENERIC_6348_WLAN_A34_3-06-02-01/userapps/opensource
$ wget http://download.jabberd.org/jabberd14/jabberd14-1.6.1.1.tar.gz
$ tar xvf jabberd14-1.6.1.1.tar.gz
$ cd jabberd14-1.6.1.1
$./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1

This ends badly:

...
checking for libpopt... configure: error: no

Apparently the library for parsing command line parameters is needed. This was reported a year ago ...

2. popt

$ cd GENERIC_6348_WLAN_A34_3-06-02-01/userapps/opensource
$ wget http://freshmeat.net/redir/popt/72854/url_tgz/popt-1.14.tar.gz
$ tar xvf popt-1.14.tar.gz
$ cd popt-1.14
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
...
checking for va_copy() function... configure: error: cannot run test program while cross compiling
See `config.log' for more details.

WTF! There's bug 25 about it that the developers closed, saying "va_copy is no longer needed or used in popt-1.14.". Hell, when it's not needed, why did you keep the check ...
I added a comment to the bug and sucessfully run:

$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 ac_cv_va_copy=no
$ make
$ make install

1b. jabberd
Retry:

$ cd ../jabberd14-1.6.1.1
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
...
checking for libpopt... configure: error: no

The previous step did not help much ... The configure script does not search for the popt.h in the provided directories - again something reported a year ago. It forced me to rise bug 93.
Retry:

$ CPPFLAGS="-I/var/usb/usb_1/include" ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
...
checking for GNUTLS... no
No package 'gnutls' found
configure: error: Couldn't find required GnuTLS installation

Fine, let's get GnuTLS working first. Furthermore, ./configure --help reveals that some more libraries are needed by jabberd:

  --with-libidn=DIR       Where to find libidn (required)
  --with-libpth=DIR       Where to find libpth (required)
  --with-expat=DIR        Where to find libexpat (required)

In addition GnuTLS requires some other libraries, libtasn1 and libgcrypt, so let's get them all first.

3. GNU Portable Threads

$ cd ..
$ wget ftp://ftp.gnu.org/gnu/pth/pth-2.0.7.tar.gz
$ tar xvf pth-2.0.7.tar.gz
$ cd pth-2.0.7
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
$ make
$ make install

4. Expat XML Parser

$ cd ..
$ wget http://downloads.sourceforge.net/expat/expat-2.0.1.tar.gz?modtime=1181083143&big_mirror=0
$ tar xvf expat-2.0.1.tar.gz
$ cd expat-2.0.1
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
$ make
$ make install

5. GNU IDN Library - Libidn

$ cd ..
$ wget ftp://alpha.gnu.org/pub/gnu/libidn/libidn-1.8.tar.gz
$ tar xvf libidn-1.8.tar.gz
$ cd libidn-1.8
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
$ make
$ make install

6. Tiny ASN.1 library - Libtasn1

$ cd ..
$ wget http://josefsson.org/gnutls/releases/libtasn1/libtasn1-1.4.tar.gz
$ tar xvf libtasn1-1.4.tar.gz
$ cd libtasn1-1.4
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
$ make
$ make install

To save me from

checking for gpg-error-config... no
checking for GPG Error - version >= 1.4... no
configure: error: libgpg-error is needed.
                See ftp://ftp.gnupg.org/gcrypt/libgpg-error/ .

when configuring libgcrypt, libgpg-error has to be done in advance.

7. libgpg-error

$ cd ..
$ wget ftp://ftp.gnupg.org/gcrypt/libgpg-error/libgpg-error-1.6.tar.bz2
$ tar xvf libgpg-error-1.6.tar.bz2
$ cd libgpg-error-1.6
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
$ make
$ make install

8. libgcrypt

$ cd ..
$ wget ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.4.1.tar.gz
$ tar xvf libgcrypt-1.4.1.tar.gz
$ cd libgcrypt-1.4.1

The path to libggpg-error has to be specified explicitly:

$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-gpg-error-prefix=/var/usb/usb_1 --with-pth-prefix=/var/usb/usb_1

But it still does not help!:

$ make
...

I found out the guys at OpenWRT had the same problem and have a patch available. I wanted to file a bug to the GnuPG bug tracker, but did not receive the confirmation mail when registering... Actually this was told to the author two years ago and he does not care at all.
So here goes the needed modification:

To prevent a configure error

checking for libgcrypt-config... no
checking for LIBGCRYPT - version >= 1.2.4... no
configure: error:
***
*** libgcrypt was not found. You may want to get it from
*** ftp://ftp.gnupg.org/gcrypt/libgcrypt/

the prefix to libgcrypt has to be specified (and libtasn1 too, to avoid using the built-in one):

$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-libgcrypt-prefix=/var/usb/usb_1 --with-libtasn1-prefix=/var/usb/usb_1 

but it still does not work:

After some experimentation (I told you I am no programmer) I found the following to work:

$ LIBS="-ltasn1 $LIBS" ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-libgcrypt-prefix=/var/usb/usb_1 --with-libtasn1-prefix=/var/usb/usb_1
$ make
$ make install

Also I found that the two official mirrors have both different directory structure, so I was missing the devel branch of GnuTLS. The above works with http://www.gnu.org/software/gnutls/releases/gnutls-2.3.14.tar.bz2 (and breaks with 2.2.5).

1c. jabberd
Let's not try to find more bugs and specify the needed components to the configure script now:

$ cd ../jabberd14-1.6.1.1
$ CPPFLAGS="-I/var/usb/usb_1/include" ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-libidn=/var/usb/usb_1 --with-libpth=/var/usb/usb_1 --with-expat=/var/usb/usb_1

but still bad luck:

checking for GnuTLS... checking for mipsel-linux-pkg-config... no
checking for pkg-config... /usr/bin/pkg-config
configure: WARNING: In the future, Autoconf will not detect cross-tools

configure: error: Couldn't find required GnuTLS installation

And again, reported a year ago. We can fix that, but the show is still not at the end:

$ PKG_CONFIG_PATH=/var/usb/usb_1/lib/pkgconfig CPPFLAGS="-I/var/usb/usb_1/include" ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-libidn=/var/usb/usb_1 --with-libpth=/var/usb/usb_1 --with-expat=/var/usb/usb_1

Quick look into config.log reveals something familiar:

/opt/toolchains/uclibc-crosstools_gcc-3.4.2_uclibc-20050502/bin/../lib/gcc/mips-linux-uclibc/3.4.2/../../../../mips-linux-uclibc/bin/ld: warning: libtasn1.so.3, needed by /var/usb/usb_1/lib/libgnutls-extra.so, not found (try using -rpath or -rpath-link)

/var/usb/usb_1/lib/libgnutls.so: undefined reference to `gcry_sexp_release@GCRYPT_1.2'
...

Let's see if the GnuTLS fix works here as well:

LIBS="-ltasn1 $LIBS" PKG_CONFIG_PATH=/var/usb/usb_1/lib/pkgconfig CPPFLAGS="-I/var/usb/usb_1/include" ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-libidn=/var/usb/usb_1 --with-libpth=/var/usb/usb_1 --with-expat=/var/usb/usb_1
...
checking for stringprep_check_version in -lidn... no

No, it doesn't , but config.log reveals we got one step further:

...

Finally, this works:

but make fails:

This turned out to be easy, the Gentoo folks found and patched it couple of months ago (and it looks it is in the jabberd cvs now) and after applying it, the journey ends:

$ make
$ make install

Wow, congratulations!!

Let's get an editor so that we can modify the config files in place:

10a. vim

$ cd ..
$ wget ftp://ftp.vim.org/pub/vim/unix/vim-7.1.tar.bz2
$ tar xvf vim-7.1.tar.bz2

...
checking for strip... strip

  (cross compiling doesn't work)

Would you expect an opensource app as big and widespread as Vim to be so broken? I would now. Fortunately the OpenWRT and FreeWRT people come to help again.

$ wget --no-check-certificate https://dev.openwrt.org/browser/packages/utils/vim/patches/001-cross_compile.patch?format=txt
$ patch -p1 <001-cross_compile.patch\?format\=txt

      You need to install a terminal library; for example ncurses.
      Or specify the name of the library with --with-tlib.

Seems some terminal library is needed ...

11. The Ncurses (new curses) library

$ cd ..
$ wget http://ftp.gnu.org/pub/gnu/ncurses/ncurses-5.6.tar.gz
$ tar xvf ncurses-5.6.tar.gz
$ cd ncurses-5.6
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1
$ make
$ make install

10b. vim

$ cd ../vim71
$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-features=tiny
...

      You need to install a terminal library; for example ncurses.
      Or specify the name of the library with --with-tlib.

seems we have to force it:

$ ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-features=tiny --with-tlib=ncurses 
$ make
...

hmm, I guess I really need to use the CPPFLAGS, shouldn't I modify the environment file? Perhaps, but now it's too late, it's finished:

$ make distclean
$ CPPFLAGS="-I/var/usb/usb_1/include/ncurses" ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1 --with-features=tiny --with-tlib=ncurses --disable-gui --disable-gtktest --disable-xim --without-x --disable-multibyte --disable-netbeans --disable-cscope --disable-gpm

No, it's not finished... Let's just hack it:

$ diff -u src/Makefile.old src/Makefile

 ### Program to run on installed binary

$ make install

I was quite surprised with the size of some files. Performing /opt/toolchains/uclibc-crosstools/bin/mipsel-linux-sstrip on bin/ and lib/ helped a bit, but 1MB of vim suggests there's still place for optimizations.

Final creation and writing of the squashfs image:

# /home/hajma/Dokumenty/asus/squashfs2.0r2/squashfs-tools/mksquashfs /var/usb/usb_1 /tmp/new.sqsh -be -noI -noD -noF
# dd if=/tmp/new.sqsh of=/dev/sda1

In the next part I'll try to correctly configure jabberd and make it start at router boot.

Nejspis jsem uplne mimo ale mozna by bylo lepsi psat podobne clanky cesky, pokud nekdo umi anglicky dost na tohle tak si odpovidajici informace *asi* dovede najit sam ...

[Jardík]

Why the fu*k is this in English?

Když už se chceš vytahovat svou angličtinou (jestli je to vůbec tvoje), tak tam alespoň nesekej takový debilní chyby ...

[hajma]

Anglicky to píšu protože si myslím, že to tak bude k něčemu většímu počtu lidí. Jestli je moje se starej až po prvním vydání JXP commanderu. A jestli tam mám chyby, tak mi řekni kde.

[Smajchl]

Hmm a já se na to radši vykašlu to číst protože to je v angličtině. Kdyby to bylo česky tak si to třeba i přečtu...

[Nikola Ciprich]

tak to je ovsem nestesti

[Jardík]

Např. si uvědom, kde se používá "some" a kdy se používá "a".

[hajma]

Konečně něco konstruktivního. Až budu psát další, tak nad tím zkusím zapřemýšlet.

[Mykonou]

Debilni chyby? Nerekl bych ze v tom clanku je neco z ceho by si clovek umejici nejak rozumne anglicky rval vlasy.

[Nikola Ciprich]

tez mi to prijde celkem OK. btw autorovi zapisku dik, taky uvazuju ze si rozjedu vlastni jabber server, tak to mozna vyuziju :)

[Jakub Hájek]

Nejses ty posledni dobou nejak moc chytrej a protivnej?

[Jardík]

Je to možné, ale to bude tím, že mám smíšenou poruchu osobnosti schizoidní a dissociální.

[Miloslav Ponkrác]

Až tento článek objeví windowsáci, tak to bude hlavní propagační materiál, proč si nezačínat s Linuxem.

[hydrandt]

Zato kdyby na tom routeru běhaly Windows, samozřejmě by to šlo a bylo by to krásně jednoduché, co?

[Miloslav Ponkrác]

Bez Windows se v síti nehnete Windows jsou pro síť tak důležitá, že dokonce v TCP hlavičce je položka windows size Takže si konečně přiznejte, že Windows jsou pro síť nesmírně důležitá věc

Hi, thank you for the article. I have been looking for a resolution of problem with compiling jabberd14 1.6.1 in Debian Lenny (issue with removed trustdb support in GnuTLS 2.4, which is in Lenny) and found a link to patch in your post.
