#12849: hsc2hs trouble with floating-point constants in cross-compilation mode -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: hsc2hs | Version: 7.8.4 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Split off from #7983. GCC 4.6 rejects some uses of floating-point constants in the declaration of a local static array. From ticket:7983#comment:5:
This is caused by a regression in GCC from gcc-4.4 to gcc-4.6: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=46028
{{{ $ cat Test_hsc_test0.c void _hsc2hs_test1() { static int test_array[(89.) > 0 ? 2 : 1]; }
$ /usr/bin/gcc-4.4 -c ./Test_hsc_test0.c
$ /usr/bin/gcc-4.6 -c ./Test_hsc_test0.c ./Test_hsc_test0.c: In function ‘_hsc2hs_test1’: ./Test_hsc_test0.c:3:16: error: storage size of ‘test_array’ isn’t constant }}}
This means that (if your C compiler is affected by this issue) hsc2hs can't handle {{{ (#const 89.) }}} in cross-compilation mode. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12849 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
