[Buildroot] Host libxml-parser-perl build issue

[Will Newton]

Hi all,

I have a build failure building avahi on a CentOS 5 system (old, but
not ancient) which is caused by the configure script failing to load
the XML::Parser perl module. buildroot has built a host version of
libxml-parser-perl and also a host version of expat, but the configure
for avahi is still failing. The reason for this appears to be that
perl cannot find libexpat.so, presumably because it is not in the
shared library search path. The attached patch fixes it but seems like
quite a far-reaching change, does anybody have any opinions on it?

Thanks,

Hello,

I guess it looks like:
http://autobuild.buildroot.org/results/4a9ad56f4690d6958164fac72bce8b97db6d2356/build-end.log

Correct?

If so, do you have Perl to the target enabled in your configuration?

Regards,

Thomas

Yes, that's what it looks like. I can get a full log of build output
when I am back in the office.

No, the only perl stuff being built is for host tool dependencies.

Ok.

Ah, ah, strange. So far, our conclusion was that this issue was related
to the selection of Perl for the target. At least that's what we can
conclude from the build tests visible at http://autobuild.buildroot.net.

So definitely, having your .config + build log would be interesting.

Attached is the config and build log (only the last part as I forgot
to tee to a file!). The host system has the following installed:

[win at lemeta01 buildroot]$ rpm -q expat
expat-1.95.8-8.3.el5_5.3
expat-1.95.8-8.3.el5_5.3
[win at lemeta01 buildroot]$ rpm -q perl
perl-5.8.8-32.el5_5.2

I get a failure when I try and load XML::Parser without LD_LIBRARY_PATH set:

[win at lemeta01 buildroot]$ PERLLIB=./output/host/usr/lib /usr/bin/perl
-e "require XML::Parser"
