The cmake output reports that your compiler does not accept the command-line options that cmake tests for, but a comment in the cmake code suggests that it may still work.<br>

Hi developers,<br>
<br>
I try to compile the latest 4.6 either with an mvapich2 (based on icc 11.0) on a Xeon Woodcrest. cmake gives the strange output:<br>
<br>
-- Detecting best acceleration for this CPU - SSE2 # correct for a Woodcrest<br>
-- Performing Test CFLAGS_SSE2 - Failed # ????<br>
-- Enabling SSE2 Gromacs acceleration, and it will help compiler optimization.<br>
-- Performing Test GNU_SSE2_CFLAG - Failed (not sure if that is expected when using icc)<br>
<br>
When compiling with mvapich2, I get the error<br>
<br>
/usr/users/cmb/shared/src/gmx/<u></u>gromacs/include/types/../gmx_<u></u>cpuid.h(260): error: identifier "FILE" is undefined<br>
FILE * log);<br>
<br>
My cmake call is pretty normal (and yields cmake output):<br>
<br>
source /usr/product/parallel/<u></u>mvapich2/intel/bin/mpivars.sh<br>
export CC=`which mpicc` # looks ok<br>
export CXX=`which mpicxx` # also ok<br>
export FFTW_LOCATION=/usr/users/jhub/<u></u>opt/fftw/fftw33/nehalem/build<br>
<br>
rm -fr CMakeFiles CMakeCache.txt cmake<br>
export CMAKE_PREFIX_PATH=$FFTW_<u></u>LOCATION<br>
export LANG=C<br>
$cmake /usr/users/cmb/shared/src/gmx/<u></u>gromacs \<br>
-DCMAKE_INSTALL_PREFIX=$(pwd) \<br>
-DGMX_X11=OFF \<br>
-DCMAKE_C_COMPILER=$CC \<br>
-DCMAKE_CXX_COMPILER=$CXX \<br>
-DGMX_MPI=ON \<br>
-DGMX_GPU=OFF \<br>
-DGMX_PREFER_STATIC_LIBS=ON \<br>
-DGMX_GIT_VERSION_INFO=OFF<br>
<br>
Any ideas what the error and the cmake output means?<br>
<br>
Many thanks,<br>
