[Y]es from me it almost goes without saying. ________________________________________ From: sage-devel@googlegroups.com [sage-devel@googlegroups.com] on behalf of Volker Braun [vbraun.n...@gmail.com] Sent: Tuesday, 28 January 2014 0:40 To: sage-devel@googlegroups.com Subject: [sage-devel] Pkgconfig as standard spkg
One general problem with combining libraries into larger projects is that * the package providing of the library knows best about the necessary compiler/linker flags, but * packages using the library must specify the compiler/linker flags Pkgconfig is the standard for solving this problem, http://en.wikipedia.org/wiki/Pkg-config. It consists of a helper commandline program pkg-config and plain-text configuration files (*.pc) that contain the compiler/linker flags necessary. The library then just has to install a suitable libfoo.pc file, and the users of the library call e.g. "pkg-config --cflags libfoo" to get the compiler flags. At http://trac.sagemath.org/15742, have packaged * a command-line implementation (pkgconf) of the pkgconfig spec * and a python interface to pkg-config and propose to make it a standard spkg. In the future, spgk-install scripts shall use pkgconfig whenever possible.In particular, I'm working with Francois Bissey to use pkgconfig for packages using blas/cblas/lapack. This will allow us to switch between different blas/cblas/lapack implementations just by exchanging the pkgconfig (*.pc) files. This is the obligatory "new spkg" vote... -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
