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
