Patch to fix cross-compiling

Patch to fix cross-compiling

[George McCollister]

[-- Attachment #1: Type: text/plain, Size: 428 bytes --]

I've created a patch against your SVN trunk which uses 
ax_cc_for_build.m4 to provide CC_FOR_BUILD which is then used in 
auparse/Makefile.am and lib/Makefile.am to build the utilities that run 
on the build machine.

I was able to use this patch to cross-compile audit for my ARM platform. 
I'm still in the process of testing audit on the ARM platform.

Comments, questions and critiques welcome.

Regards,
George McCollister

Well...it breaks the normal build on x86_64:

config.status: creating tools/auvirt/Makefile
config.status: creating config.h

Works for me on x86_64. Did you remember to run autogen.sh so configure 
gets regenerated before running configure? If that doesn't help it would 
be helpful to get your lib/Makefile so I could analyze it.

Thanks,
George

I have a script that I use for testing all patches wrt the build. It have 2 
modes, one that pulls a fresh copy from svn to check for missing files and one 
that just uses the local svn cache so I can test prior to pushing. It does 
something like this:

cwd=`pwd`
mkdir audt
cd audit
cp -r $trunk/* .
./autogen.sh
./configure --with-prelude -with-libwrap
make -j 8 dist
mv audit-$release.tar.gz ~/working/audit/
cd $cwd
rpmbuild -ba ../audit/audit.spec

Its failing under the rpmbuild which does not use the autogen script.

But there is another problem I didn't notice right away...it adds a new file, 
m4/ax_cc_for_build.m4. In it is this:

+#   This program is free software: you can redistribute it and/or modify it
+#   under the terms of the GNU General Public License as published by the
+#   Free Software Foundation, either version 3 of the License, or (at your

The audit package is strictly GPL/LGPL v2.

I'll try to find a different solution.
