Re: [commit: ghc] master: By default, use the dynamic way for programs in the GHC tree (b712667)

Hi Austin, I see I've completely forgotten to mention that this is on ARM/Linux builder machine so I'm completely out of control of generating build.mk in this case. Thanks, Karel On 03/18/13 11:07 PM, Austin Seipp wrote:

I ran into this earlier today. It's because your build.mk http://build.mk is now out of date; just blow it away and copy the build.mk.sample file over again and set your BuildFlavour.

However, the stage2 build will later fail because it doesn't think that LLVM supports -fPIC and -fdynamic on ARM. The patch to fix this is simple and it will unblock the build, but we'll need to do some work beyond that - the fallout from using the combo dynamic/static way seems to have broken some stuff (stage2 no longer builds with LLVM 3.2 for me...)

I will push shortly.

Hello Ian,

am I right assuming that this patch breaks ARM/Linux compilation which now fails with:

===--- building phase 0 make -r --no-print-directory -f ghc.mk http://ghc.mk phase=0 phase_0_builds ghc.mk:133 http://ghc.mk:133: *** dyn is not in $(GhcLibWays), but $(DYNAMIC_GHC_PROGRAMS) is YES. Stop. make: *** [all] Error 2

If so, will you fix this or shall I provide a patch?

Thanks, Karel

By default, use the dynamic way for programs in the GHC tree

In particular, this means that GHCi will use DLLs, rather than loading object files itself.
