[mpich-discuss] MPICH2 1.3.2 build using Intel Fortran, Gcc

[Anthony Chan]

Hi John,

The config.log indicates that your ifort refuses to link with object file
produced by your version of gcc 4.5.  Listed below is the steps of the
failed test:

configure:8742: checking whether Fortran 77 and C objects are compatible
configure:8772: gcc -c    -O2 conftestc.c 1>&5
configure:8775: $? = 0
configure:8794: ifort -c   -O2 conftestf.f 1>&5
configure:8797: $? = 0
configure:8808: ifort   -O2 -o conftest conftestf.o conftestc.o   >&5
IPO link: can not find "("
ifort: error: problem during multi-file optimization compilation (code 1)

I think gcc 4.5 is a much newer version of gcc than the ifort 9 can handle.
Do you have icc that comes with your version of ifort ?
