Full Text Bug Listing

The media-libs/allegro-4.0.3 ebuild fails because the compile doesn't find 
#include <artsc.h>, apparently because of a missing include path in the gcc 
invocation.

Reproducible: Always
Steps to Reproduce:
1. ACCEPT_KEYWORDS=~x86 emerge allegro
2.
3.

Actual Results:  
Here's a tail of the output. Note that the final gcc command does not have an 
include path for /usr/kde/3.1/include or /usr/kde/3.1/include/artsc/ ... I do 
not have artsc.h anywhere else on my system.

Expected Results:  
Uh, should have compiled! :)

Created an attachment (id=11454) [details]
ebuild that should correct the problem

I had the same problem
the problem arise because the include path to artsc.h was stocked in a CFLAGS
variable which was overriden by our CFLAGS
I corrected it by concatening the 2 vars

This worked just fine for me, thanks!
I recommend applying the patch in CVS and resolving this FIXED.

turn down your CFLAGS and try again

ok, added a similar fix when i cleaned up the ebuild
enjoy !@
