hsc2hs breaks with `--cflag=-Werror` in cross-compilation mode
I would like to be able to do
config_args='--target=i386-unknown-linux --with-gcc=i386-unknown-linux-gcc' ./validate
to validate a 32-bit GHC on a 64-bit Linux system. (I don't know why I have to specify --with-gcc
in addition to --target
; an unrelated mystery.)
However validate
sets -Werror
and the C code that hsc2hs
generates in cross-compilation mode is not always warning-free, e.g.,
Files.hsc: In function ‘_hsc2hs_test’:
Files.hsc:81:14: error: variable ‘test_array’ set but not used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors
so hsc2hs
draws incorrect conclusions from its tests.
Either the hsc2hs
-generated C code should be made (and kept) warning-free, or perhaps hsc2hs
should append -Wwarn
to the options that it passes to the C compiler.
