[CMake] static cmake, ctest executables

[Ilias Miroslav]

Dear Eric,

yes, I would like to have static cmake execs for usage in (sometimes unequipped) grid environment;

I tried your buildup prescription, but got dynamic execs,

and  cmake's buildup step ignored the most importan flag:

Any help, please ?

Fully static may be achieved with

cmake -DBUILD_SHARED_LIBS=OFF -DCMAKE_EXE_LINKER_FLAGS_DEBUG=-static
/path/to/source

I assume you compile CMake using cmake and not bootstrapping it.
CMAKE_EXE_LINKER_FLAGS_<BUILDTYPE> specifies an extra linker flags when building
executable.

Doing this spit warning like:

".../Utilities/cmcurl/hostip4.c:183: warning: Using 'gethostbyname_r'
in statically linked applications requires at runtime the shared
libraries from the glibc version used for linking"

If you dig into the CMake ML, I think you should find some discussion
about the issue
you may have to get fully static executable on Linux or more precisely
with glibc.

Stackoverflow has some entry on the subject as well:
http://stackoverflow.com/questions/3430400/linux-static-linking-is-dead

You may try to get rid of libgcc and libstdc++
using
-static-libgcc
and
-static-libstdc++

see
http://www.trilithium.com/johan/2005/06/static-libstdc/

Are you sure you really need fully static executable?
