Description:
lapack doesn't ship a symbolic link liblapack.so (to liblapak.so.3). This causes a strange behavior:

$ cc -llapack test.c -o test
/tmp/cceccmis.o: In function `main':
test.c:(.text+0x12): undefined reference to `lsame_'
collect2: ld returned 1 exit status
$? = 1

$ cc test.c -llapack -o test
$? = 0

Both commands works after doing "ln -s /usr/lib/liblapack.so.3 /usr/lib/liblapack.so" (as root)

I found this problem with scilab: the configure scripts try the second form, deduce that it can use the system lapack, try to link with the first form, and fails. I will report this problem to scilab too and make a workaround, but it would be nice to be able to dynamically link with lapack. Creating the dynamic link solved the problem, too.

Lapack version: 3.1.1-3
