Repository navigation
doesn't load specified .so files #14
Description
My project has some .so files as part of its FFI bindings. I cannot seem to get hdevtools to use them.
I tried including the filenames with -g mylib.so , which is what cabal passes to ghc, and which also works with ghci to load the modules using this, but it seems hdevtools doesn't do anything with them, since I get a failure like this:
During interactive linking, GHCi couldn't find the following symbol:
diskfree
The only workaround I have found is to pass -DNO_LIBS and then #ifdef out all imports of modules using them..

How do you invoke ghci to use your .so file?

Ugly, but that works great with cabal.
I manually tweaked that for hdevtools, yielding this:
hdevtools check git-annex.hs -g -cpp -g -i -g -idist/build/git-annex/git-annex-tmp -g -i. -g -idist/build/autogen -g -Idist/build/autogen -g -Idist/build/git-annex/git-annex-tmp -g -IUtility -g -DWITH_TESTSUITE -g -DWITH_S3 -g -DWITH_ASSISTANT -g -DWITH_INOTIFY -g -DWITH_DBUS -g -DWITH_PAIRING -g -DWITH_XMPP -g -optP-include -g -optPdist/build/autogen/cabal_macros.h -g -odir -g dist/build/git-annex/git-annex-tmp -g -hidir -g dist/build/git-annex/git-annex-tmp -g -stubdir -g dist/build/git-annex/git-annex-tmp -g -threaded -g -Wall -g -XHaskell98 -g dist/build/git-annex/git-annex-tmp/Utility/libdiskfree.o -g dist/build/git-annex/git-annex-tmp/Utility/libmounts.o
That works, except for the libraries not loading, and the CPP inclusion
of dist/build/autogen/cabal_macros.h apparently not working either.
