I wanted to discuss this before reporting as a bug in case I'm doing something wrong. I had a user request support for Oracle Solaris Studio compilers, so I installed them to try them out. I downloaded the latest 12.2 and installed it to /opt/oracle/solstudio12.2 on my x86_64 RHEL5 workstation. The compilers I used are suncc, sunCC and sunf90 for the C, C++ and Fortran 90 compilers, respectively. Our software is a mostly C, with some Fortran and a C++ binding. We use AC_F77_LIBRARY_LDFLAGS. configure fails with "linking to Fortran libraries from C fails" because " /usr/bin/ld: cannot find -lmtsk". The result of the AC_F77_LIBRARY_LDFLAGS test appears at the end of this email. The library is located in /opt/oracle/solstudio12.2/prod/lib/compilers/rtlibs/usr/lib/amd64 which is found in the -Y argument in the verbose linking output: -Y "/opt/oracle/solstudio12.2/prod/lib/compilers/rtlibs/usr/lib/amd64:/opt/oracle/solstudio12.2/lib/amd64:/opt/oracle/solstudio12.2/prod/lib/amd64:/lib64:/usr/lib64" The man page for /usr/bin/ld claims -Y is supported for Solaris compatibility, so why is it not parsed out into FLIBS? config.log for AC_F77_LIBRARY_LDFLAGS: configure:13457: checking for Fortran 77 libraries of sunf90 configure:13480: sunf90 -o conftest -v conftest.f -lm ### f90: Note: NLSPATH = /opt/oracle/solstudio12.2/prod/bin/../lib/locale/%L/LC_MESSAGES/%N.cat:/opt/oracle/solstudio12.2/prod/bin/../../lib/locale/%L/LC_MESSAGES/%N.cat ### command line files and options (expanded): ### -o conftest -v conftest.f -lm /opt/oracle/solstudio12.2/prod/bin/f90comp -m3 -ev -dq -xall -xivdep=loop -H "/opt/oracle/solstudio12.2/prod/bin/f90 -v -lm " -I/opt/oracle/solstudio12.2/prod/include/f95/amd64 -p/opt/oracle/solstudio12.2/prod/lib/modules/amd64 -xarch=amd64 -y-xarch=amd64 -xmemalign=1i -iorounding=processor-defined -xhasc=yes -xcache=generic -y-xcache=generic -y-xassume_control=optimize -xassume_control=optimize -fstore -y-xdbggen=no%stabs+dwarf2 -y-xdbggen=incl -y-fbe -y/opt/oracle/solstudio12.2/prod/bin/fbe -y-fsr=34 -y-verbose -y-comdat -y-xarch=amd64 -y-comdat -y-xthreadvar=no%dynamic -y-o -yconftest.o -y-s conftest.f /opt/oracle/solstudio12.2/prod/bin/fbe -s -o conftest.o -xarch=amd64 -xmodel=small -warn=%none -Qy /tmp/yabekxuSWF rm /tmp/yabekxuSWF ### f90: Note: LD_LIBRARY_PATH = /home/d3n000/ga/openmpi-1.4.3-amd/local/lib:/home/d3n000/ga/local/lib:/home/d3n000/ga/ga-dev/bld_openmpi_shared/lib ### f90: Note: LD_LIBRARY_PATH_64 = (null) ### f90: Note: LD_RUN_PATH = (null) ### f90: Note: LD_OPTIONS = (null) /usr/bin/ld --eh-frame-hdr -m elf_x86_64 -dynamic-linker /lib64/ld-linux-x86-64.so.2 --enable-new-dtags /opt/oracle/solstudio12.2/prod/lib/amd64/crti.o /opt/oracle/solstudio12.2/prod/lib/amd64/crt1x.o /opt/oracle/solstudio12.2/prod/lib/amd64/values-xi.o conftest.o -lm -o conftest -Y "/opt/oracle/solstudio12.2/prod/lib/compilers/rtlibs/usr/lib/amd64:/opt/oracle/solstudio12.2/lib/amd64:/opt/oracle/solstudio12.2/prod/lib/amd64:/lib64:/usr/lib64" -Qy "-R/opt/oracle/solstudio12.2/prod/lib/compilers/rtlibs/usr/lib/amd64:/opt/oracle/solstudio12.2/lib/amd64" -lfai -lfui -lfsu -lsunquad -lmtsk -lpthread -lm -lc /opt/oracle/solstudio12.2/prod/lib/amd64/libc_supp.a /opt/oracle/solstudio12.2/prod/lib/amd64/crtn.o rm conftest.o configure:13654: result: -lm -lfai -lfui -lfsu -lsunquad -lmtsk -lpthread /opt/oracle/solstudio12.2/prod/lib/amd64/libc_supp.a _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
