[CMake] CHECK_TYPE_SIZE("size_t" SIZEOF_SIZE_T) failed while crosscompile

[Claus Klein]

Hallo,

the following Modules use TRY_RUN, which must fail while crosscompile:

claus at P3linux:~/downloads/cmake-2.4.5/Modules> grep TRY_RUN *.cmake
# OK CheckCSourceRuns.cmake:    TRY_RUN(${VAR} ${VAR}_COMPILED
# OK CheckCXXSourceRuns.cmake:    TRY_RUN(${VAR} ${VAR}_COMPILED
CheckTypeSize.cmake:    TRY_RUN(${VARIABLE} HAVE_${VARIABLE}
FindThreads.cmake:        TRY_RUN(THREADS_PTHREAD_ARG THREADS_HAVE_PTHREAD_ARG
TestBigEndian.cmake:    TRY_RUN(${VARIABLE} HAVE_${VARIABLE}


tested with my buildroot cross tool chain (uclibc based) on a linux host:

cd ~/src/wzdftpd/trunk/build && 
rm -f CMakeCache.txt &&
CC=/tools/Linuxi386CDK/bin/i386-linux-gcc \
CXX=/tools/Linuxi386CDK/bin/i386-linux-g++ \
AR=/tools/Linuxi386CDK/bin/i386-linux-ar \
PKG_CONFIG_PATH=/tools/WITH_TCLDevLinuxi386CDK/lib/pkgconfig PKG_CONFIG_DEBUG_SPEW=1 \
CMAKE_LIBRARY_PATH=/tools/Linuxi386CDK/lib:/tools/Linuxi386CDK/usr/lib \
CMAKE_INCLUDE_PATH=/tools/Linuxi386CDK/include:/tools/Linuxi386CDK/usr/include \
cmake -DWITH_GnuTLS=OFF -DWITH_PostgreSQL=OFF -DWITH_MySQL=OFF -DWITH_Zeroconf=OFF .. 


Too, I can't prevent too find host TCL libs which should not used:

claus at P3linux:~/src/wzdftpd/trunk/build> cmake -DWITH_GnuTLS=OFF -DWITH_PostgreSQL=OFF -DWITH_MySQL=OFF -DWITH_Zeroconf=OFF -L ..

What can I do if a package has not an Option like: WITH_TCLDev

Any Ideas?
