I am unable to build lapack-atlas 3.7.39: [...] checking for BLAS... configure: error: Package requirements (blas) were not met: No package 'blas' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables BLAS_CFLAGS and BLAS_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

Created attachment 133073 [details] config.log Here is the requested lapack-atlas-3.7.39/work/lapack-lite-3.1.1/config.log for bug reports
*** This bug has been marked as a duplicate of bug 193884 ***
Re-opening: different version. Could you show the output of these: * eselect blas list * eselect cblas list * pkg-config --libs blas cblas Thanks

What blas implementations do you have installed? Thanks, Markus

Info: lukuss ~ # eselect blas list Installed BLAS for library directory lib64 [1] atlas * [2] reference [3] threaded-atlas lukuss ~ # eselect cblas list Installed CBLAS for library directory lib64 [1] atlas * [2] gsl [3] reference [4] threaded-atlas lukuss ~ # pkg-config --libs blas cblas Package blas was not found in the pkg-config search path. Perhaps you should add the directory containing `blas.pc' to the PKG_CONFIG_PATH environment variable No package 'blas' found Package cblas was not found in the pkg-config search path. Perhaps you should add the directory containing `cblas.pc' to the PKG_CONFIG_PATH environment variable No package 'cblas' found After that I change blas and cblas to reference: lukuss ~ # eselect blas set reference lukuss ~ # eselect cblas set reference lukuss ~ # pkg-config --libs blas cblas -lcblas -lblas And switch back to atlas: lukuss ~ # eselect cblas set atlas lukuss ~ # eselect blas set atlas lukuss ~ # pkg-config --libs blas cblas -lblas -lcblas -latlas Now I can compile lapack-atlas. Comment: I was not able to directly reset blas to atlas if it was already selected: lukuss ~ # eselect blas set atlas Implementation "atlas" already active for library directory "lib64"! Failed to switch to implementation "atlas" for library directory "lib64"! !!! Error: One or more actions have failed! Killed Thanks, Drix
(In reply to comment #7) I've the same blas configuration as Drix (at least an identical output from "eselect blas/cblas list") and can confirm the work around.
Should be fixed by now, was probably a amd64 get_libdir bug. If not, re-open and provide info as requested on comment #3 together emerge --info for those who have not provided. If you don't want to re-sync and re-emerge the blas-atlas now, then just run the following bit: $ rm -f /etc/env.d/*blas/lib*/config && eselect blas set atlas && eselect cblas set atlas. Replace atlas with threaded-atlas if you want the threaded version.
