Bug 648386 – sci-libs/atlas - *** No rule to make target 'liblapack.a', needed by 'libclapack.a'. Stop

I have tried several possible solutions, but always the final lines are:

make -j5 libclapack.a
*** No rule to make target 'liblapack.a', needed by 'libclapack.a'.  Stop

During the build, there are several complaints about inability to use SSEGEN and (numerous) "target specific option mismatch".

Please attach a full build log.

The problem is gone after adding "-mavx -msse4.2" to CFLAGS in /etc/portage/make.conf. I feel this should not be necessary. Also, this addition does not affect the gfortran command line.

Please attach the entire build log to this bug report.

As a side remark, an include file (atlas/atlas_type.h) appears as missing:

atlas_misc.h:#include "atlas_type.h"

Same problem here.
The first error was :

error: inlining failed in call to always_inline ‘_mm256_load_pd’: target specific option mismatch 

and the compilation dies later with the following text :

*** No rule to make target 'liblapack.a', needed by 'libclapack.a'.  Stop

I retried with -mavx -msse4.2 and it now compiles and works.

/proc/cpuinfo tells me :

[...]

So I guess there is something wrong somewhere :)

Here the problem is similar but the output differs, at the end of the build log the messages show the libclapack.a related error:

 * ERROR: sci-libs/atlas-3.10.2::gentoo failed (compile phase):

adding avx sse4_2 to CPU_FLAGS_X86 makes no difference but interestingly adding -mavx -msse4.2 to CFLAGS somehow caused the missing file(s) to be created or libclapack.a to not be required. The error concerns the install phase, not the compile phase. Anyway, this workaround fixes the atlas build for me but does not make me happy.
