Hi all,
The test for checking "-no-pie" support of GCC doesn't seem to work. See below:
$ gcc --version gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4) Copyright (C) 2010 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
$ echo 'int main() { return 0; }' > conftest.c
$ if gcc -o conftest -no-pie conftest.c > /dev/null 2>&1 ; then echo YEP ; else echo NOPE ; fi YEP $ if gcc -o conftest -no-pie conftest.c ; then echo YEP ; else echo NOPE ; fi gcc: unrecognized option '-no-pie' YEP $ if gcc -o conftest -no-pie conftest.c > /dev/null ; then echo YEP ; else echo NOPE ; fi gcc: unrecognized option '-no-pie' YEP
Is the test supposed to check that there is nothing output into stdout?
Oh dear; it seems that GCC prior to 4.8 doesn't exit with a non-zero exit code when faced with an unrecognized flag. Could you verify that https://phabricator.haskell.org/D2707 fixes this? Cheers, - Ben
