OK, I can understand that. But if the options (-mtune ***, -msse2)
are not longer available with the actual free Intel Compiler suites,
shouldn't the cmake definitions be adapted to this fact in order
to avoid loads of compiler warnings?
If someone can identify a way to detect old and new, free and non-free compiler
suites then we might consider it. Reality is that GROMACS spends a heavy
majority of its time in loops written mostly in assembly code (using SSE or
SSE2 if applicable), or in
the FFT library. Compiler performance makes a negligible contribution to
performance of the rest, so it is really not worth while maintaining complex
compiler tweaks.
OK,
I'll attach the error messages err.msg, 5.9 KB).
- cmake version 2.8.3
- gcc 4.5.1 x64 (Linux) (20101208)
With cmake 2.8.2 and icc 12.1.0 20110811 using the aforementioned flags, I get
smooth installation of the git version of 4.5.5. Moreover, I don't even get
.../build/src/gmxlib/CMakeFiles/CMakeRelink.dir
being created. So I think there is something idiosyncratic about your tool
chain that is at the root of this.
I replicated the error on another machine and already answered this
as a response to Szilárd. I really don't know what the reason is, maybe
I'm doing something really wrong. The only ray of hope: w/autoconf,
everything works fine, even giving one the subjective impression of
'closely controlling' the build process ;-)
Thanks & regards
