With all that, the first problem I hit was with utils/pwd/pwd. ./configure builds it by calling ghc without any special flags, so the binary can't find libgmp.so at runtime.

I think you need to tell the dynamic linker where to find it, e.g. by setting DYLD_LIBRARY_PATH. See the dyld manpage for more information.

I'm on GNU/Linux, so it would be LD_LIBRARY_PATH for me. Yes, that would be another useable workaround for pwd. What about the other problems I mentioned? Regardless of my problems, it seems like a build bug that SRC_HC_OPTS isn't used for some compilations. Is SRC_HC_OPTS meant to be used for all Haskell compilations in the build process, or am I misunderstanding its purpose?

The next problem was with cabal-bin. The command to build it didn't use SRC_HC_OPTS, so that binary also couldn't find libgmp.so when it ran. I used this patch:

That gets me to this point:

I'm not sure how to fix this. I assume there's some way to pass SRC_HC_OPTS to cabal-bin, but I don't know how.

I thought all your problems boiled down to binaries not being able to find libgmp.so at runtime? So I think this should fix them all.

Yes, but then I wouldn't be able to find and fix the commands that are missing SRC_HC_OPTS. :) So I'm holding off on that for now. Below is a patch for the ones I've found so far. With those changes, and without setting LD_LIBRARY_PATH, the build stops here: Preprocessing library hpc-0.5.0.2... dist-bootstrapping/build/Trace/Hpc/Reflect_hsc_make: error while loading shared libraries: libgmp.so.3: cannot open shared object file: No such file or directory running dist-bootstrapping/build/Trace/Hpc/Reflect_hsc_make failed command was: dist-bootstrapping/build/Trace/Hpc/Reflect_hsc_make >dist-bootstrapping/build/Trace/Hpc/Reflect.hs My BUILD_FLAGS includes --ghc-option=-optl... and --ld-option=... flags which would take care of it, if they were being used, so apparently they're not. libraries/hpc/Trace/Hpc/Reflect.hsc produces libraries/hpc/dist-bootstrapping/build/Trace/Hpc/Reflect_hsc_make.c, which is compiled and linked to make libraries/hpc/dist-bootstrapping/build/Trace/Hpc/Reflect_hsc_make. Is there anything I can add to the cabal-bin command line to inject linker flags into that link command? --- libraries/Makefile 2008-10-07 15:30:24.000000000 -0400 +++ libraries/Makefile 2008-10-31 11:58:25.000000000 -0400 @@ -131,21 +131,21 @@ cabal-bin: cabal-bin.hs -mkdir bootstrapping - $(GHC) $(BOOTSTRAPPING_FLAGS) --make cabal-bin -o cabal-bin + $(GHC) $(BOOTSTRAPPING_FLAGS) $(SRC_HC_OPTS) --make cabal-bin -o cabal-bin bootstrapping.conf: cabal-bin echo "[]" > $@.tmp -cd filepath && $(CABAL) clean --distpref=dist-bootstrapping cd filepath && $(CABAL) configure --distpref=dist-bootstrapping --with-compiler=$(GHC) --with-hc-pkg=$(GHC_PKG) --package-db=$(HERE_ABS)/$@.tmp - cd filepath && $(CABAL) build --distpref=dist-bootstrapping + cd filepath && $(CABAL) build --distpref=dist-bootstrapping $(BUILD_FLAGS) cd filepath && $(CABAL) install --distpref=dist-bootstrapping --inplace -cd Cabal && $(CABAL) clean --distpref=dist-bootstrapping cd Cabal && $(CABAL) configure --distpref=dist-bootstrapping --with-compiler=$(GHC) --with-hc-pkg=$(GHC_PKG) --package-db=$(HERE_ABS)/$@.tmp - cd Cabal && $(CABAL) build --distpref=dist-bootstrapping + cd Cabal && $(CABAL) build --distpref=dist-bootstrapping $(BUILD_FLAGS) cd Cabal && $(CABAL) install --distpref=dist-bootstrapping --inplace -cd hpc && $(CABAL) clean --distpref=dist-bootstrapping cd hpc && $(CABAL) configure --distpref=dist-bootstrapping --with-compiler=$(GHC) --with-hc-pkg=$(GHC_PKG) --package-db=$(HERE_ABS)/$@.tmp - cd hpc && $(CABAL) build --distpref=dist-bootstrapping + cd hpc && $(CABAL) build --distpref=dist-bootstrapping $(BUILD_FLAGS) cd hpc && $(CABAL) install --distpref=dist-bootstrapping --inplace mv $@.tmp $@ @@ -154,9 +154,9 @@ mkdir ifBuildable $(CP) ifBuildable.hs ifBuildable/ ifeq "$(stage)" "2" - cd ifBuildable && ../$(HC) -Wall --make ifBuildable -o ifBuildable + cd ifBuildable && ../$(HC) -Wall $(SRC_HC_OPTS) --make ifBuildable -o ifBuildable else - cd ifBuildable && $(GHC) -Wall --make ifBuildable -o ifBuildable + cd ifBuildable && $(GHC) -Wall $(SRC_HC_OPTS) --make ifBuildable -o ifBuildable endif .PHONY: all build configure
