Revision 1.39, Fri Jan 3 11:11:29 2020 UTC (8 months, 2 weeks ago) by pho
Branch: MAIN
Changes since 1.38: +4 -3 lines

Explicitly set the ld command to ${LD}

Without doing this the resulting compiler will have a cwrapper ld
embedded, and will be unable to bootstrap later versions of GHC.

# GHC requires GHC to build itself. Formerly we could work around this
# bootstrapping problem by creating a special archive containing C
# sources compiled from Haskell sources, but that's no longer
# possible. So we have to prepare stripped-down binaries sufficient to
# bootstrap compilers for each platforms. If you want to build them
# yourself, follow instructions in BOOTSTRAP.txt and ./bootstrap.mk

# LDFLAGS is currently not honored by "./configure". Since LDFLAGS

# does more harm than good because our ${LDFLAGS} contains -Wl,*
# flags. It's true that ../../mk/wrapper/cmd-sink-ld transforms them
# but those flags will also be baked into the compiler (see
# ${WRKSRC}/compiler/ghc.mk) so they cause problems when used outside

# The runtime system of GHC (rts) tends to conflict with PaX MPROTECT
# because it needs to generate various kinds of code at run time. The
# RTS linker, whose job is to load *static* objects at run time,
# doesn't play nice with ASLR either. This means most executables
# produced by GHC need them to be disabled. Perhaps we should patch
# rts/sm/Storage.c so that it uses ffi_closure_alloc(3) on every
# platform, not just Linux, and also drop support for static library
# loading and switch to dynamic libraries entirely.
