I have a package (PARI) installed under /usr/local.
I have this (in a different package which wants to use PARI):
=== configure.in ===
AC_MSG_NOTICE([* PARI (Headers)])
AC_CHECK_HEADERS(pari/pari.h, break)
if test "$ac_cv_header_pari_pari_h" = "no";
then AC_MSG_ERROR([cannot find PARI headers])
fi
AC_MSG_NOTICE([ * PARI (Functions):])
AC_SEARCH_LIBS(pari_kernel_init, pari)
if test "$ac_cv_search_pari_kernel_init" = "no";
then AC_MSG_ERROR([cannot find PARI library])
fi
=== configure.in ===
I get this:
checking pari/pari.h usability... yes
checking pari/pari.h presence... yes
checking for pari/pari.h... yes
configure: * PARI (Functions):
checking for library containing pari_kernel_init... no
configure: error: cannot find PARI library
and in config.log:
configure:2970: gcc -o conftest.exe -g -O2 conftest.c -lpari >&5

how come gcc looks in /usr/local/include but not in /usr/local/lib?
