This comes from Sources/cmCoreTryCompile.cxx, there FindOutputFile() apparently was not successful in finding the linked executable. The value of CMAKE_EXECUTABLE_SUFFIX is used there. You need a valid setpu for creating executable, i.e. the suffix must be set and also the CMAKE_C/CXX_LINK_EXECUTABLE variables must be set properly. Can you please post the CMakeOutput.log and CMakeError.log from when that happens ? You may also dig into the code and check what's going wrong :-) Alex _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
