Hi,
I'm trying to use GNU autotools (automake-1.10.1, autoconf-2.61 and
libtool-2.2.4) for linking Fortran libraries. First I compile two
libraries in separate directories, lib1/libx.la and lib2/liby.la.
There libtool is doing what I want, ie.
make[1]: Entering directory `/home/username/src/f95/libtoytest/lib1'
/bin/bash ../libtool --mode=compile gfortran -g -O2 -c -o xmod.lo xmod.f95
libtool: compile: gfortran -g -O2 -c xmod.f95 -o xmod.o
/bin/bash ../libtool --mode=link gfortran -g -O2 -o libx.la
-rpath /home/us
ername/tmp/toytest/lib xmod.lo
and similarly for the second library lib2/liby.la.
But, when I try to combine libx.la and liby.la together to libxy.la,
libtool is not using gfortran for linking (but gcc):
make[1]: Entering directory `/home/username/src/f95/libtoytest'
/bin/bash ./libtool --tag=CC --mode=link gcc -g -O2 -o libxy.la
-rpath /hom
e/username/tmp/toytest/lib lib1/libx.la lib2/liby.la
libtool: link: gcc -shared -Wl,-rpath
-Wl,/home/ppiirola/src/f95/libtoytest/li
b1/.libs -Wl,-rpath -Wl,/home/ppiirola/src/f95/libtoytest/lib2/.libs
-Wl,-rpath
-Wl,/home/ppiirola/tmp/toytest/lib lib1/.libs/libx.so
lib2/.libs/liby.so -Wl,-soname -Wl,libxy.so.0 -o .libs/libxy.so.0.0.0
What should I have in configure.ac and Makefile.am to force
libtool to use gfortran for linking? Currently the files are:
# cat configure.ac
AC_INIT([toytest],[0.01],[x...@xx.x])
AM_INIT_AUTOMAKE([-Wall -Werror])
AC_PREREQ([2.59])
LT_PREREQ([2.2.4])
AC_CONFIG_MACRO_DIR([m4])
AC_PROG_INSTALL
AC_PROG_FC([gfortran])
AC_COPYRIGHT([(c) <x...@xx.x>])
AC_CONFIG_FILES([
Makefile
lib1/Makefile
lib2/Makefile])
LT_INIT
LT_LANG([Fortran])
AC_OUTPUT
and
# cat Makefile.am
ACLOCAL_AMFLAGS= -I m4
SUBDIRS = lib1 lib2
lib_LTLIBRARIES = libxy.la
libxy_la_SOURCES =
libxy_la_LIBADD = lib1/libx.la lib2/liby.la
Thanks for the help!
