Dear GHC developers and users, Could you, please, help with ghc-pkg ? (in ghc-6.4) The contrived testing project is of the two small modules M1.hs, M2.hs. (find enclosed the source). `Makefile' is set so that make dm should compile the modules and put *.hi, *.o modules and .a, .o libraries to $(s)/export/. It also needs to create a package dm-1.0 (in 6.2.2 it was dm ). A particular command in Makefile is ghc-pkg -f $(s)/dm-1.0.conf -u -g , which (as I recall) makes the .o library from .a one. It worked in 6.2.2 -- with dm instead of dm-1.0, with `=' instead of `:' and with package_deps = ["data"] in the package specification. And in 6.4, make dm reports ... " Reading package info from stdin... done. ghc-pkg: invalid package identifier: " Packages always were difficult. And in 6.4 they are changed again ... Question 2: recompilation ------------------------- Why does it recompile both modules when after the first make dm we remove the .a library and repeat make dm ? This recompilation bites when there are many modules. Thank you in advance for explanation. ------------------ Serge Mechveliani mechvel@botik.ru ------------------------------------------------------------ module M1 -- file M1.hs where tuple31 :: (a, b, c) -> a tuple31 (x, _ ,_) = x --------------------------------- file M2.hs module M2 where import qualified Data.Set as Set (Set(..), singleton) import M1 (tuple31) f :: Set.Set Bool f = Set.singleton $ tuple31 (True, False, False) -- Makefile ------------------------------------------------------ ghcBinDir = /usr/bin s = /home/mechvel/ghc/6.4/pkgTest e = $(s)/export ghc = $(ghcBinDir)/ghc ghcpkg = $(ghcBinDir)/ghc-pkg RANLIB = ar -s HCFlags = -odir $(e) -hidir $(e) -ddump-hi-diffs pack = Package {name : ["\"dm-1.0\""], \ import_dirs : ["\"$(e)\""], \ source_dirs : [], \ library_dirs : ["\"$(e)\""], \ hs_libraries : ["\"HSdm\""], \ extra_libraries : [], \ include_dirs : [], \ c_includes : [], \ package_deps : [], \ extra_ghc_opts : [], \ extra_cc_opts : [], \ extra_ld_opts : [] } # of 6.2.2: name = ["\"dm\""], \ # package_deps = [\"data\"], \ obj: if [ ! -d $(e) ]; then mkdir $(e); fi $(ghc) $(HCFlags) --make M2 -package-name dm-1.0 dm: obj rm -f $(e)/libHSdm* $(e)/HSdm* ar -qc $(e)/libHSdm.a $(wildcard $(e)/*.o) $(RANLIB) $(e)/libHSdm.a $(RANLIB) $(e)/libHSdm.a echo $(pack) | $(ghcpkg) -f $(s)/dm-1.0.conf -u -g $(ghcpkg) -f $(s)/dm-1.0.conf -l ------------------------------------------------------------------ make dm yields ----------------------------------------------------------- if [ ! -d /home/mechvel/ghc/6.4/pkgTest/export ]; then mkdir /home/mechvel/ghc/6.4/pkgTest/export; fi /usr/bin/ghc -odir /home/mechvel/ghc/6.4/pkgTest/export -hidir /home/mechvel/ghc/6.4/pkgTest/export -ddump-hi-diffs --make M2 -package-name dm-1.0 Chasing modules from: M2 Source file changed or recompilation check turned off Compiling M1 ( ./M1.hs, /home/mechvel/ghc/6.4/pkgTest/export/M1.o ) No old interface file Source file changed or recompilation check turned off Compiling M2 ( M2.hs, /home/mechvel/ghc/6.4/pkgTest/export/M2.o ) No old interface file rm -f /home/mechvel/ghc/6.4/pkgTest/export/libHSdm* /home/mechvel/ghc/6.4/pkgTest/export/HSdm* ar -qc /home/mechvel/ghc/6.4/pkgTest/export/libHSdm.a /home/mechvel/ghc/6.4/pkgTest/export/M1.o /home/mechvel/ghc/6.4/pkgTest/export/M2.o ar -s /home/mechvel/ghc/6.4/pkgTest/export/libHSdm.a ar -s /home/mechvel/ghc/6.4/pkgTest/export/libHSdm.a echo Package {name : ["\"dm-1.0\""], import_dirs : ["\"/home/mechvel/ghc/6.4/pkgTest/export\""], source_dirs : [], library_dirs : ["\"/home/mechvel/ghc/6.4/pkgTest/export\""], hs_libraries : ["\"HSdm\""], extra_libraries : [], include_dirs : [], c_includes : [], package_deps : [], extra_ghc_opts : [], extra_cc_opts : [], extra_ld_opts : [] } | /usr/bin/ghc-pkg -f /home/mechvel/ghc/6.4/pkgTest/dm-1.0.conf -u -g Reading package info from stdin... done. ghc-pkg: invalid package identifier: make: *** [dm] Error 1 ----------------------------------------------------------
