Hello,
It would be useful for the end user to use mpic++ to obtain the compile and
link flags for both release and debug builds.
There is a number of possible solutions:
1. add the showme flags of mpic++ and any other similar binary to
something like -showme:compile_debug -showme:compile_release
-showme:link_release -showme:link_debug
2. add a -showme_debug flag to tune the -showme:compile -showme:link
3. have 2 versions of the binary mpic++(release) and mpic++(debug)
4. have 1 version of the mpic++ but 2 versions of the of
wrapper-data.txt file
5. have 1 version of mpic++ and 1 version of the wrapper-data file,
and 2 sections in the wrapper-data file
It would be great to have this delivered in the win binaries package
(include both release and debug libs, that's already the case), and advise
3rd party packagers on unix/linux/mac distributions to do similarily
It would be also useful to publish the cmake flags used by default to
produce the win binaries
I am available to test the packages if possible, also is there a wiki for
requests or a similar system where I should file the above.

Hi,
There is no easy solution. But you can try to use WANT_EXE_DEBUG_POSTFIX
option in CMake GUI. Enabling this option will generate different
executable.library names for debug and release build. For example,
mpic++d.exe for debug and mpic++.exe for release.
For you case, just build both debug and release version of Open MPI 1.5.4,
and install them into the same path, you will get two sets of
executables/libraries (with "d" postfix for debug version) and mpic++ config
files (mpic++d-wrapper-data.txt for debug version). Then just append your
own debug/release compile options in the config files, and build with boost
mpi as you need.
Hope this helps.
Regards,
Shiqing

Hello,
Compiling boost mpi library uses mpic++ to get the compile flags to pass to
cl.exe and link libs to pass to the linker.
In my case:
>>> mpic++ -showme:compile
/I"C:\Program Files\openmpi\bin/../include" /TP /EHsc /MD
>>> mpic++ -showme:link
/link /LIBPATH:"C:\Program Files\openmpi\bin/../lib" libmpi_cxx.lib
libmpi.lib libopen-pal.lib libopen-rte.lib advapi32.lib Ws2_32.lib
shlwapi.lib
To choose Release build or Debug build, is it possible to use
mpic++-wrapper-data.txt to specify both options?
Release
/MD
libmpi_cxx.lib libmpi.lib libopen-pal.lib libopen-rte.lib advapi32.lib
Ws2_32.lib shlwapi.lib
Debug
/MDd
libmpi_cxxd.lib libmpid.lib libopen-pald.lib libopen-rted.lib advapi32.lib
Ws2_32.lib shlwapi.lib
is there a debug version of "advapi32.lib Ws2_32.lib shlwapi.lib"
For now, I will just override that file for Release, build boost mpi,
override for Debug, build for Debug.
thanks,
MM
