Re: linker cant locate a 3rd party lib

[Jack Nguyen]

LDFLAGS is already defined in my configure.ac. In fact i use it to do
AC_CHECK_LIB(mkl,some_func). the problem is when i try to test my
libfoo.la, it cant find the library it libfoo.la depends on. the
console output is
$libtool gcc -o test test.c libfoo.la
gcc -o test test.c ./.libs/libfoo.a -L /src/dir/ -lmkl_lapack -lm
/usr/bin/ld cannot find -lmkl_lapack
I want gcc to look into the -L /mkl/lapack/dir, not just /src/dir
