#10237: compiler/ghci/LibFFI.hsc:42 sizeof(ffi_cif) is not an integer -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by erikd): Ok, here's the problem: {{{ LibFFI.hsc: In function ‘_hsc2hs_test’: LibFFI.hsc:11:14: error: variable ‘test_array’ set but not used [-Werror =unused-but-set-variable] cc1: some warnings being treated as errors }}} It seems `hsc2hs` generates some test files to measure the size of values that looks like this: {{{ void _hsc2hs_test() { static int test_array[1 - 2 * !((long long)(sizeof(ffi_cif)) == (sizeof(ffi_cif)))]; test_array[0] = 0; } }}} The value of `test_array[0]` is set but not used. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10237#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
