#3761: 6.12.1 HC bootstrap failes due to suspicious static library ordering
---------------------------------+------------------------------------------
Reporter: PHO | Owner:
Type: bug | Status: new
Priority: normal | Component: Build System
Version: 6.12.1 | Keywords:
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: Building GHC failed
---------------------------------+------------------------------------------
I found ghc-stage2 doesn't link because of the order of static libraries
passed to gcc. The problem occurs on FreeBSD but I believe it's platform-
independent.
The build system puts rts/dist/build/libHSrts.a followed by
rts/dist/build/libHSrtsmain.a. The latter has an undefined symbol to
"hs_main" which is defined in libHSrts.a, so the linker complains about
the absence of hs_main.
The following patch to rts/ghc.mk solves the problem:
{{{
