Description Diego Elio Pettenò (RETIRED) gentoo-dev 2008-10-24 17:55:15 UTC
I'm filing this bug (from a template, mind you) because the ebuild I'm reporting it against failed to build once I removed my /usr/bin/{gcc,cc,c++,c99} binaries. This means that the ebuild is relying on gcc or cc as compiler, while it should use "$(tc-getCC)" so that user choices are respected, and cross-compiling works as intended.

This usually comes down to one of these tasks:

- use emake CC="$(tc-getCC)" for building, to ovewrite make's CC variable (defaults to "cc", some upstream rewrites it);
- the above plus replacing explicit "gcc" (or similar) calls with $(CC) so that the variable is actually respected;
- tc-export CC in src_compile before eventual econf.

For C++, you'd have to replace CC with CXX everywhere above, of course.

If your package is a special case on this, please let me know.


P.S.: this happens during check, not build.

Good catch, indeed CC is not respected.

For testing I removed /usr/bin/{gcc,cc,c++,c99} locally.
While trying to make shm compile with Intel CC I found that "cc" is called directly from  I made a patch for it which made it compile with ICC, reading CC properly.  As upstream states "This module isn't being developed anymore" I did not take the patch online.

+  26 Jun 2010; Sebastian Pipping <> shm-1.2.2.ebuild,
+  +files/shm-1.2.2-compiler.patch:
+  Fix to respect CC variable (bug #243966)

Closing.  Thanks Diego.
