Bug 504618 – dev-python/numpy-1.8.0-r1 - pc_libs() fails to remove all duplicate libraries

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description whgentoo 2014-03-14 17:29:18 UTC]

Start from line 63
pc_libs() {
        $(tc-getPKG_CONFIG) --libs-only-l $@ | \
          sed -e 's/[ ]-l*\(pthread\|m\)\([ ]\|$\)//g' \
           -e 's/^-l//' -e 's/[ ]*-l/,/g' -e 's/[ ]*$//' \
          | sort | uniq | tr '\n' ','
}

The function intends to remove duplicate libs returned by pkg-config, however it doesn't.

A quick fix can be done by changing line 66.

pc_libs() {
        $(tc-getPKG_CONFIG) --libs-only-l $@ | \
          sed -e 's/[ ]-l*\(pthread\|m\)\([ ]\|$\)//g' \
           -e 's/^-l//' -e 's/[ ]*-l/,/g' -e 's/[ ]*$//' \
          | tr ',' '\n' | sort | uniq | tr '\n' ','
}

thanks for the patch. Looks good to me. @python?

scipy also has the same bug. 

It only breaks the compilation when pkg-config returns the same libs for blas and cblas (e.g. MKL).

Python-2.7.5
