[gmx-users] ADD_LIBRARY cmake error on Bluegene/Q

[Hardy, Adam]

Hi Mark,

I was able to compile GROMACS on Marenostrum, the cmake version is "2.6-patch 2".

On Fermi it failed, the cmake version is "2.8.8". 

This is not necassarily a fair comparison. I compiled using gnu on Marenostrum as I couldn't find the xl compiler oddly and wasn't feeling compelled to go looking for it. I'm using xl on Fermi as using gnu is another problem all together:

CMake Error at cmake/gmxManageSimd.cmake:390 (message):
  Cannot compile the requested IBM QPX intrinsics.  If you are compiling for
  BlueGene/Q with the XL compilers, use 'cmake ..
  -DCMAKE_TOOLCHAIN_FILE=Platform/BlueGeneQ-static-XL-C' to set up the tool
  chain.

Despite the correct file being specified and I can see the path set correctly in the CMakeCache.txt. 

Adam

Hi,

Do the cmake versions differ?
