Howdy all! I am a programmer on a free software scientific data package called libcf, to be used by climate scientists to make their data more interoperable. I am trying to use the AC_SEARCH_LIBS macro to find a fortran library. I have read this tread in the mailing list, in which it is stated that the user must set FCFLAGS and LDFLAGS to point to the fortran directories that contain the mod and library files. (http://www.mail-archive.com/autoconf@xxxxxxx/msg17020.html) But what if it is installed in a standard location, like /usr/local? When I test for C libraries, I don't have to put a -I/usr/local/include in CPPFLAGS, it just finds it there. Why can't fortran do the same thing? Or am I missing something here? Also, I agree with the poster on that thread who contends that fortran will not correctly compile the test program conftest.f with the use LIBRARY statement. I am trying to get my library (libcf) to find another fortran library that should be already installed: the netCDF library. I am trying this: AC_LANG_PUSH(Fortran) AC_FC_SRCEXT(f90) AC_SEARCH_LIBS([nf90_open], [netcdf]) AC_LANG_POP(Fortran) Which generates the following test program: configure:5217: gfortran -o conftest -g -O2 conftest.f90 >&5 /tmp/ccaZquLl.o: In function `main': /home/ed/snapshot/lb_new2/conftest.f90:2: undefined reference to `nf90_open_' collect2: ld returned 1 exit status configure:5217: $? = 1 configure: failed program was: | program main | call nf90_open | end In fact, the smallest test program I can get gfortran to compile is: program main use netcdf res = nf90_open('lll', 0, ncid) end program main Does anyone use the AC_SEARCH_LIBS macro with fortran?
