libxml2 fixes

There are a few issues with libxml2.
- It depends on BR2_USE_WCHAR (which in reality, it doesn't)
- xml2-config exports the wrong paths
- it tries to build everything, python modules, etc
- libxml2.la is installed, which has a wrong path, causes issues when linking using libtool, just remove it.

Here's a patch to clean that up...

When I tried to build libxml2 using a toolchain without wchar support
it failed, when it is built with a toolchain supporting wchar, it completes the build.

When was this and with what version of libxml2, and on what architecture? On x86 and arm, that is not the case from my experience.
Can you also provide some more information on the actual error message?

Thanks.

2-3 weeks ago.

libxml2 version from buildroot.

generic-arm architecture.

I killed that toolchain, so I do not have the error handy
You can easily generate a new gcc-4.2.0/binutils-2.17 toolchain based on uClibc 0.29 without wchar for generic-arm.

Perhaps the rest of my patch resolved those issues as I am unable to recreate your issue when using my patch. I just verified that I do NOT have BR2_USE_WCHAR
enabled (Toolchain Options ---> Enable WCHAR support is NOT checked). I could not
get libxml2 to compile at all without apply patches, but it didn't give any issues related to wchar that I could see, it was because it was trying to build stuff like the python module ...

Hi Brad,

After i applied ur patch, i am getting an error when compilling libxml2
as missing xml-config file

<snip>

rm -f /home/guru/project/original/toolchains/buildroot/build_arm/staging_dir/usr/lib/libxml2.la /home/guru/project/original/toolchains/buildroot/toolchain_build_arm/bin/sed

make: *** [/home/guru/project/original/toolchains/buildroot/build_arm/libxml2-2.6.29/libxml2.la] Error

But i see that xml-config is in my buildroot/build_arm/libxml2-2.6.29
directory. i think its not copied to build_arm/staging_dir/usr/bin/. kindly let me know if i can manually copy the same or i should add/make any changes.

Well, the 'make install' inside the libxml2.mk is responsible for copying over the xml2-config to your staging_dir's usr/bin directory.

Can you run:
make libxml2-clean
rm -rf build_arm/libxml2-2.6.29

then run 'make' and see if libxml2 builds and installs? Perhaps it didn't re-run the configuration step after the patch...

If that doesn't work, I'll go ahead and probably get rid of the 'make install', and just copy the files over directly (that's what Gumstix's fork of buildroot does, and they may have had an actual reason for it). Odd I can't reproduce your situation though.

BTW, make libxml2-dirclean will properly remove and clean out the source build directory for you.

Hi All,

I tried Make libxml2-clean, make libxml2-dirclean & then make libxml2 but
still xml-config was not copied. but when tried make libxml2-headers it copied xml-config properly. dont know why. anyway thanks for all your help.

Hope someone can help me like this with glib libintl issue .

Odd, still can't reproduce...
It looks like Ulf committed the libxml2 patch, so you might try to update your svn and see if it works there...

I just did

make libxml2-clean
make libxml2-dirclean
make libxml2

Tried it with both the headers option on and off ...
Maybe you're svn is out of sync somehow, not really sure... I'd probably need to see more of your debug output (where your <snip>'s were in the original e-mail).

Seems the Python support could be the culprit.
While compiling "libxml.c" it complains that

    ".../python2.5/unicodeobject.h:118:21" wchar.h: No such file or directory.
