Hello, I am trying to compile some F77 subroutines as shared objects for R on my Mac. --> Mac OS-X Version 10.4.11 (Tiger Intel Mac)
I have done this (successfully) before on Sun Solaris and Linux Fedora systems using the following command. > R CMD SHLIB myfile.f I have g77 installed from this page. http://hpc.sourceforge.net/ I am using R 2.8.1, and I have installed all 4 additional packages including gfortran. When I try to compile my subroutines (which worked on two other systems), I get the following error. (I have also tried a very simple subroutine and produced the same error message.) chad-r-bhattis-computer:~/MyR/Examples/Fortran/Test1 chadrbhatti$ R CMD SHLIB two.f gfortran -arch i386 -fPIC -g -O2 -c two.f -o two.o gcc -arch i386 -std=gnu99 -dynamiclib -Wl,-headerpad_max_install_names -mmacosx-version-min=10.4 -undefined dynamic_lookup -single_module -multiply_defined suppress -L/usr/local/lib -o two.so two.o -lgfortran -F/Library/Frameworks/R.framework/.. -framework R -Wl,-framework -Wl,CoreFoundation /usr/bin/libtool: for architecture cputype (16777223) cpusubtype (3) object: /usr/local/lib/libgfortran.dylib malformed object (unknown load command 4) /usr/bin/libtool: for architecture cputype (16777223) cpusubtype (3) object: /usr/local/lib/libgcc_s.10.4.dylib malformed object (unknown load command 4) make: *** [two.so] Error 1 chad-r-bhattis-computer:~/MyR/Examples/Fortran/Test1 chadrbhatti$ which g77 /usr/local/bin/g77 chad-r-bhattis-computer:~/MyR/Examples/Fortran/Test1 chadrbhatti$ which gfortran/usr/local/bin/gfortran Would anyone happen to understand this error? The words "malformed object" and "cpusubtype" concern me. Note: I am much more of a Unix user than administrator. I have very limited administrator knowledge and vocabulary. I appreciate any help. Many Thanks, Chad R.
