#13355: gmp doesn't build correctly when cross-compiling with clang -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Building GHC Unknown/Multiple | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- The commit in #8497 added this to `libraries/integer-gmp/gmp/ghc.mk`: {{{ CLANG = $(findstring clang, $(shell $(CC_STAGE1) --version)) ifeq "$(CLANG)" "clang" CCX = $(CLANG) else CCX = $(CC_STAGE1) endif }}} and does the build with `$(CCX)` rather than `$(CC_STAGE1)`. However, when cross-compiling, `$(CC_STAGE1)` could be a clang cross- compiler, but then it's certainly not right to use `$(CLANG) = clang`, as that is presumably not a cross-compiler. I don't understand why the issue in #8497 arose in the first place, so it's unclear to me how to proceed here. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13355 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
