Re: linker cant locate a 3rd party lib

[Jack Nguyen]

Hi,
I have solved the previous problem and have successfully build
libfoo.la but not m encountering another.
I have src/foo and src/bar where a function bar_func.c is using a foo_func.c
and thus #include foo_func.h. But the problem is foo_func.h is not
installed in includedir until user types make install. Thus my
compiler is throwing an error that it cant find foo_func.h when it is
trying to compile bar_func.c. What to do???
