|Target Version||1.8||Fixed in Version||1.8|
|Summary||0004055: configure.ac messes up with user variables CFLAGS, CPPFLAGS, LIBS and LDFLAGS and generate wrong pkgconfig files|
|Description||configure.ac messes up with user variables CFLAGS, CPPFLAGS, LIBS and LDFLAGS.|
Since these are used to generate pkgconfig files, the user flags are wrongly passed to libextractor.pc (see on Debian -D_FORTIFY_SOURCE=2).
configure.ac should use AM_CFLAGS and friends, which are then passed to automake and used by modern version of AX_CREATE_PKGCONFIG_INFO.
> Sometimes package developers are tempted to set user variables such as CFLAGS
> because it appears to make their job easier. However, the package itself
> should never set a user variable, particularly not to include switches that
> are required for proper compilation of the package. Since these variables are
> documented as being for the package builder, that person rightfully expects
> to be able to override any of these variables at build time. If the package
> developer needs to add switches without interfering with the user, the proper
> way to do that is to introduce an additional variable. Automake makes this
> easy by introducing AM_CFLAGS (see Flag Variables Ordering), but the concept
> is the same even if Automake is not used.

|Tried to fix this in SVN 36667. Could you please let me know if this fixes it for you?|
Thanks for the patch. Unfortunetaly it does not work yet. I was hoping to investigate and help on this issue, but I am no autoconf guru...
I think we should at least update AX_CREATE_PKGCONFIG_INFO to the last version (but this is not enough).
The following test shows the issue:
autoreconf -f -i
CPPFLAGS='-Wdate-time -D_FORTIFY_SOURCE=2' ./configure
At the line "checking our pkgconfig cppflags...", version 1.3 gives wrongly -Wdate-time -D_FORTIFY_SOURCE=2 and gives (which is right) all the necessary includes.
With the fix from svn 36667, it gives only -Wdate-time -D_FORTIFY_SOURCE=2, but no includes.
I will try to investigate this more in the next week-end.
Thanks to Sven Joachim for pointing this out. By updating AX_CREATE_PKGCONFIG_INFO to the last version, this seems to be fixed.
Could you please update it according to http://git.savannah.nongnu.org/cgit/autoconf-archive.git/tree/m4/ax_create_pkgconfig_info.m4

|Fixed now, sadly just saw your comment after pushing 1.7. Will be in 1.8 though.|
