[Pkg-scicomp-devel] Bug#410883: Linking libufsparse.so requires explicit linking of BLAS and C math libraries

[LUK ShunTim]

Package: libufsparse
Version: 1.2-7
Severity: important

Hello,

The current build of libufsparse.so requires explicit linking with BLAS and the 
C math library when it is used. The result of compiling umfpack_di_demo.c 
without such explicit linking showed:

$ gcc -I/usr/include/ufsparse -o umfpack_di_demo umfpack_di_demo.c \ 
      -L/usr/lib -lumfpack -lamd

It'd be much more convenient for the user if such dependency is automatically 
taken care of so that just linking with libufsparse is sufficient.
