If you run 'cmake --help-command execute_process', you see: ... If RESULT_VARIABLE is given the variable will be set to contain the result of running the processes. This will be an integer return code from the last child or a string describing an error condition. ... So, if this is not "0", then you have an error condition. > BTW, I'm still curious about the (dual 'code') construct generally. > Specifically, if I do the following I never see the fatal error message > (so I'm wondering if there's still something wrong regarding the scoping of > the message command)? > > install (CODE "EXECUTE_PROCESS ( > COMMAND ant ... > WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}/java > ERROR_VARIABLE _err > ) > MESSAGE( FATAL_ERROR \"err: ${_err}\") Never did this. When do you want to see the message? As I understand your code, only in call of cmake, e.g. at configuration time. Kornel
