Downloaded and compiled UMFPACK [1] and it went well
copied out the example program Tim Davis has written up and I got this error
me@sun:~/umfpack$ cc ex.c
/tmp/ccBVFK6B.o: In function `main':
ex.c:(.text+0x4a): undefined reference to `umfpack_di_symbolic'
ex.c:(.text+0x7b): undefined reference to `umfpack_di_numeric'
ex.c:(.text+0x87): undefined reference to `umfpack_di_free_symbolic'
ex.c:(.text+0xc6): undefined reference to `umfpack_di_solve'
ex.c:(.text+0xd2): undefined reference to `umfpack_di_free_numeric'
collect2: ld returned 1 exit status
I had originally thought that I would need to use libraries like such:
me@sun:~/umfpack$ cc ex.c -lumfpack -lamd -lcblas -latlas
but the libraries can't be found.
I had to adjust the paths for a few header files already, so this is probably the same issue , I just don't know where or what needs fixing.
Any help is much appreciated.
