Subject: Bug#171518: ghc --make does not play nice with FFI wrapper
To: Debian Bug Tracking System <[EMAIL PROTECTED]>
Reply-To: Richard Braakman <[EMAIL PROTECTED]>, [EMAIL PROTECTED]
X-Mailer: reportbug 2.9
Message-Id: <E18J1pu-0004Vc-00@night>
Package: ghc5
Version: 5.04-1
Severity: normal
I have a module SDL.Bare.Audio with this declaration:
foreign import ccall safe "wrapper"
mkSDL_AudioSpec_Callback :: SDL_AudioSpec_Callback u ->
IO (FunPtr (SDL_AudioSpec_Callback u))
When compiling Audio.hs, this results in the creation and compilation
of Audio_stub.c.
Unfortunately, if I'm using ghc --make, if it decides to skip compilation
of Audio.hs, it never realizes that it also needs to link in Audio_stub.o,
causing this failure at the end:
ghc: linking ...
build/Audio.o(.text+0x89): In function `s3Fk_ret':
: undefined reference to `SDLziBareziAudio_d3K2'
collect2: ld returned 1 exit status
I tried to work around it by putting Audio_stub.o on the command line
by hand, but then it fails when compiling from a clean tree, because
it ends up linking the file twice.
