However, now I'm getting an error while building the DPH packages (probably due to the use of TH):
Loading package vector-0.9.1 ... <command line>: can't load .so/.DLL for: /Users/christiaan/Documents/devel/ghc/libraries/vector/dist-install/build/libHSvector-0.9.1-ghc7.7.20130918.dylib (dlopen(/Users/christiaan/Documents/devel/ghc/libraries/vector/dist-install/build/libHSvector-0.9.1-ghc7.7.20130918.dylib, 9): Library not loaded: @loader_path/../primitive-0.4.0.1/libHSprimitive-0.4.0.1-ghc7.7.20130918.dylib
Referenced from: /Users/christiaan/Documents/devel/ghc/libraries/vector/dist-install/build/libHSvector-0.9.1-ghc7.7.20130918.dylib
Reason: image not found)
Of course the problem is, is that the packages are not installed yet, so the relative paths don't make sense yet.
My solution is to update rules/shell-wrapper.mk, and to add
DYLD_FALLBACK_LIBRARY_PATH = <ALL_LIBRARY_BUILD_DIRS>
to the inplace/bin shell wrappers.
So that during building of ghc, dynlibs of all the packages can still be resolved to the place where they were build.
So my question is: how do I get the list <ALL_LIBRARY_BUILD_DIRS> within the build system?
