Chih-Ping, > Thanks for your help! I installed the latest Xcode 4.5 and redo netcdf > installation, however, I still got the same error, /usr/bin/libtool: unknown > option character `f' in: -force_load Hmm, I guess the OS-X libtool is not keeping up with the gnu libtool, which supports the -force_load option. But it can be tricky, using Gnu versions of tools with Apple's gcc, for example, which has Apple additions not supported by Gnu tools. It looks like setting lt_cv_ld_force_load=no got you past that problem. I think we can solve this without needing to use a different libtool, because the error below just looks like an attempt to mix 32-bit and 64-bit objects in the same library. You need to either use all 32-bit ("-m32" flag on gcc and gfortran) or all 64-bit ("-m64" flag on gcc and gfortran). Depending on where you got them, the default for your gfortran may be 32-bit, while the default for your gcc may be 64-bit. I think you can also use -arch i386 or -arch x86_64 to specify the target machine architecture for 32-bit or 64-bit when using Apple compilers. So set CFLAGS and FCFLAGS to include matching target architecture options. For example, this worked for me: make clean && CC=cc CFLAGS='-g -m32' CXX=g++ CXXFLAGS='-g -m32' FC='gfortran -m32' FCFLAGS='-g' F77='gfortran -m32' FFLAGS='-g -O2' CPPFLAGS='-DNDEBUG -DgFortran' LDFLAGS=-m32 LIBS= FLIBS= F90LIBS= ./configure --enable-netcdf-4 --with-hdf5=/share/ed/local/mort && make check install --Russ > If I set lt_cv_ld_force_load=no, then I got a new error, can you please help > me again, > > libtool: link: gfortran -dynamiclib -Wl,-undefined -Wl,dynamic_lookup -o > .libs/libnetcdff.5.dylib .libs/fort-attio.o .libs/fort-control.o > .libs/fort-dim.o .libs/fort-genatt.o .libs/fort-geninq.o .libs/fort-genvar.o > .libs/fort-lib.o .libs/fort-misc.o .libs/fort-v2compat.o .libs/fort-vario.o > .libs/fort-var1io.o .libs/fort-varaio.o .libs/fort-varmio.o > .libs/fort-varsio.o .libs/libnetcdff.lax/libnetcdff90.a/netcdf.o > .libs/libnetcdff.lax/libnetcdff90.a/typeSizes.o -L/usr/local/lib > ../liblib/.libs/libnetcdf.dylib -lm -lz -lcurl -O2 -install_name > /usr/local/lib/libnetcdff.5.dylib -compatibility_version 7 -current_version > 7.0 -Wl,-single_module > libtool: link: dsymutil .libs/libnetcdff.5.dylib || : > warning: no debug symbols in executable (-arch i386) > libtool: link: (cd ".libs" && rm -f "libnetcdff.dylib" && ln -s > "libnetcdff.5.dylib" "libnetcdff.dylib") > libtool: link: (cd .libs/libnetcdff.lax/lt1-libnetcdff90.a && ar x > "/Users/cat/Desktop/netcdf-4.1.3/fortran/../f90/.libs/libnetcdff90.a") > libtool: link: ar cru .libs/libnetcdff.a fort-attio.o fort-control.o > fort-dim.o fort-genatt.o fort-geninq.o fort-genvar.o fort-lib.o fort-misc.o > fort-v2compat.o fort-vario.o fort-var1io.o fort-varaio.o fort-varmio.o > fort-varsio.o .libs/libnetcdff.lax/lt1-libnetcdff90.a/netcdf.o > .libs/libnetcdff.lax/lt1-libnetcdff90.a/typeSizes.o > /usr/bin/ranlib: archive member: .libs/libnetcdff.a(netcdf.o) cputype (7) > does not match previous archive members cputype (16777223) (all members must > match) > /usr/bin/ranlib: archive member: .libs/libnetcdff.a(typeSizes.o) cputype (7) > does not match previous archive members cputype (16777223) (all members must > match) > libtool: link: ranlib .libs/libnetcdff.a > ranlib: archive member: .libs/libnetcdff.a(netcdf.o) cputype (7) does not > match previous archive members cputype (16777223) (all members must match) > ranlib: archive member: .libs/libnetcdff.a(typeSizes.o) cputype (7) does not > match previous archive members cputype (16777223) (all members must match) > make[3]: *** [libnetcdff.la] Error 1 > make[2]: *** [all] Error 2 > make[1]: *** [all-recursive] Error 1 > make: *** [all] Error 2 --Russ > On Sep 27, 2012, at 8:34 PM, Unidata netCDF Support wrote: > > > Hi, > > > >> I am trying to install netcdf-4.1.3 on my mac pro (OS 10.7.4, gfortran, > >> gcc).
