Does anyone know why I get so little symbols in stage 2 compiler compared to programs built with the same stage 2 compiler? This is the build.mk I'm using BuildFlavour = quick ifneq "$(BuildFlavour)" "" include mk/flavours/$(BuildFlavour).mk endif GhcRtsHcOpts += -O0 -g3 GhcStage2HcOpts += -debug -g5 GhcLibHcOpts += -g5 GhcThreaded = NO BUILD_PROF_LIBS = NO HADDOCK_DOCS = NO BUILD_SPHINX_HTML = NO BUILD_SPHINX_PDF = NO BUILD_MAN = NO STRIP_CMD = : Symbols in stage 2 compiler built with this build.mk: $ nm /home/omer/haskell/ghc/inplace/lib/bin/ghc-stage2 | wc -l 9202 If I build `main = return ()` with the same compiler: $ cat test.hs main = return () $ /home/omer/haskell/ghc/inplace/bin/ghc-stage2 -g5 -O0 test -fforce-recomp [1 of 1] Compiling Main ( test.hs, test.o ) Linking test ... $ nm test | wc -l 35266 So it seems like a lot of symbols in the libraries are missing in the stage 2 executable. I tried setting `DYNAMIC_GHC_PROGRAMS = NO` but I got even less number of symbols in the stage 2 compiler. I also confirmed this using a debugger program I wrote which can find info table labels of objects in the heap when I run it on `test.hs` above but not when I run it on the stage 2 executable. Ömer
