----------------------+----------------------------
When building sage-7.2 with `LDFLAGS="--as-needed"`, the result is
underlinked:
{{{
from sage.rings.complex_double import CDF
ImportError: /home/mjo/src/sage.git/local/lib/libgsl.so.19: undefined
symbol: cblas_sdsdot
}}}
That first error can be avoided by adding `-lcblas` to the gsl LDFLAGS,
but a more intelligent approach is probably provided by this patch:
https://gitweb.gentoo.org/repo/gentoo.git/tree/sci-
libs/gsl/files/gsl-2.1-cblas.patch
After that's fixed...
{{{
File "sage/libs/linbox/linbox.pxd", line 7, in init
sage.matrix.matrix_integer_dense
(/home/mjo/src/sage.git/src/build/cythonized/sage/matrix/matrix_integer_dense.c:52635)
ImportError: /home/mjo/src/sage.git/local/lib/liblinboxsage.so.0:
undefined symbol: certSolveRedMP
}}}
That one can be fixed by appending `-liml` to the LDFLAGS for linbox.
Appending it to LIBS should work, too.
