Forcing using own third_party even if it exists in system.

[naquad]

Hi.

I'm doing cross-compilation for 32 linux bit system on 64 bit box with different distro.
Issue is I can't force chromium to use its own libraries.
Particularly i need libbz2.so and libpng.so. First I've been trying to do

GYP_DEFINES="target_arch=ia32 werror= use_system_libpng=0 use_system_bzip2=0" gclient runhooks --force
make -j5 BUILDTYPE=Release chrome

but chrome still was linked with system libbz2 and libpng.
I've tried to modify their GYP files and force corresponding variables to be 0 in condition section,
but that didn't help either.

Any ideas?

Regards, Daniel.

A dependency on the system libraries can be coming from Chrome, or
from any of the shared libraries that it does depend on. If you first
delete out/ and then do a build, you can tell if the bundled versions
of those libraries are getting built by the .o files that will appear
in out/

They're built, but still system libraries are linked.

What's the output of:

% objdump -x out/Release/chrome | grep NEEDED

libpng is not needed, but libbz2 is NEEDED.

How about

% cd /usr/lib/pkgconfig
% grep bz2 *

?
