* ld cannot find -lffi [not found] <CAKObCao=vTWDD_chBr9vV2UB8MqMOqxLq5_03yzYfqbKzkV-1A@mail.gmail.com> @ 2013-08-17 4:23 ` Jason Gross 2013-08-17 9:08 ` Andrew Haley 0 siblings, 1 reply; 6+ messages in thread From: Jason Gross @ 2013-08-17 4:23 UTC (permalink / raw) To: libffi-discuss I have installed libffi-3.0.13 from source. The generated Makefile tells me "toolexeclibdir = $(libdir)/../lib64", and the libraries seem to have installed there. However, the .pc file that gets installed tells pkg-config to tell ld to look in "libdir=${exec_prefix}/lib". Hence, ld cannot find -lffi when I go to compile something with "gcc `pkg-config --libs --cflags libffi`". I can workaround this by copying the contents of lib64 to lib, but this seems silly and broken. In addition to wanting this bug to be fixed, I'm curious to know where the Makefile gets lib64 from, because "grep lib64 *" tells me that the only other appearance is configure: sys_lib_dlsearch_path_spec="/lib64 /usr/lib64 /lib /usr/lib" (also makefiles.out~, but I figure that's a temporary). If it's relevant, uname -a tells me "Linux cagnode17 2.6.32-5-xen-amd64 #1 SMP Sun Sep 23 13:49:30 UTC 2012 x86_64 GNU/Linux" Thanks, Jason ^ permalink raw reply [flat|nested] 6+ messages in thread

So I guess the .pc file should be > set up to use multi_os_directory or toolexeclibdir? Yes. I don't thunk anything good can happen if your libdir doesn't correspond with your multi-os-directory. This is all really to do with autoconf and libtool; there's nothing much libffi can do about it. Andrew. ^ permalink raw reply [flat|nested] 6+ messages in thread
