Hi, I only wanted to warn you, that windows "date" command output is locale-specific, so you may get into trouble if you want to use it as anything else than a string literal.

There seems to be a trailing endline in the response given by $ENV{COMSPEC} /c date /t, so the following regex helps deleting it: STRING(REGEX REPLACE "(\r?\n)+$" "" _date "${_date}") Thanks again, JON HAITZ On 5 December 2013 22:34, Matthew Woehlke <matthew.woeh...@kitware.com> wrote: On 2013-12-05 15:46, Fraser Hutchison wrote: If you can specify CMake version 2.8.11 as a minimum, you could use the string(TIMESTAMP ...) command instead: string(TIMESTAMP _output "%d/%m/%Y") Bear in mind that these only execute when CMake runs (i.e. at configure time) rather than at build time, so strictly-speaking you're not actually grabbing the compile date. Of course you could put that in a CMake script and execute it with e.g. '${CMAKE_COMMAND} -p ${CMAKE_CURRENT_SOURCE_DIR}/get_date.cmake' in a custom command :-). Then it would truly be the compile date. (Needless to say, the script would need to write the date into some generated source file, e.g. with configure_file.) -- Matthew -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
