Linking error with icc 8.0/SuS/EM64T

[rvwilson]

I am getting the following linking errors when I attempt to build an executable:

/usr/bin/ld: skipping incompatible ../libunsio/libunsio.a when searching for -lunsio
/usr/bin/ld: cannot find -lunsio

With typical compiler command line options:

/usr/local/intel/compiler80/bin/icc -O3 -fno-alias -fno-fnalias -tpp7 -xW -fp -unroll -Ob2 -ip -fPIC -Duxint=int -DLINUX -DSIMC_DOUBLE -Duxreal=double -Duxjacreal=float -I/usr/local/include -I/usr/local/hdf5/include -I../libswiss -I../libunsio -I../libuns -I../libparuns -I../libuxinput -I../libsdb -I../libh5layer -I../libdistfunc -I../libuxuser -I../libNISTThermo -I/usr/local/mpich-1.2.6/include -I. -c multigrid.C

Even though the compiler was able to successfully compile the ../libunsio/libunsio.a library. I am using SuSe Linux v9.2 and running with a EM64T Xeon processor. I assume that the problem is that the libunsio.a library if not compatiable due to 32bit-vs-64bit issues. If this is the case, do you have any ideas about how to fix this problem?

Thanks,
Bob

Yes, the files to be linked together must be all 32-bit or all 64-bit. If you are using the 32-bit icc, the linker will skip over 64-bit libraries and produce the message you quoted. If you have available 64-bit libraries of everything for which you don't have source code, you must be running on the x86-64 OS. You should upgrade to the 64-bit 8.1 or 9.0 icc, or get all 32-bit libraries. If you need to check your system for existence of 32- and 64-bit library versions, you could use the find and file commands.
