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? If so, it seems to fail. It leads to lots of failures when "make test", because gcc gets chatty. Cheers, Gabor PS: I have bash 4.1.

Hi all,

$ 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

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
