Re: Problems compiling with profiling enabled

I can get everything to compile with the -prof flag now, but I get those 
two linking errors that I don't understand:

c:/ghc/ghc-6.2.1/libHSGLUT_p.a(Debugging.p_o)(.text+0x748):Debugging.p_hc: 
undefined reference to 
`GraphicsziRenderingziOpenGLziGLUziErrors_getErrors_closure'
c:/ghc/ghc-6.2.1/libHSGLUT_p.a(Debugging.p_o)(.text+0x7a4):Debugging.p_hc: 
undefined reference to 
`GraphicsziRenderingziOpenGLziGLUziErrors_getErrors_entry'
make: *** [renderer] Error 1

My configuration is a bit weird: I compile HOpenGL and GLUT from a 6.3 
fptools distribution, but I install the resulting packages in a 6.2.1 
binary distribution (because for some reason I don't remember I was 
having trouble building the whole fptools 6.3).
I'm using cygwin on a win XP PC.

In case it's relevent, the package.conf entries for GLUT and OpenGL read 
like this:

Package
    {name = "OpenGL",
     auto = True,
     import_dirs = ["$libdir/imports"],
     source_dirs = [],
     library_dirs = ["$libdir"],
     hs_libraries = ["HSOpenGL"],
     extra_libraries = ["HSOpenGL_cbits"],
     include_dirs = [],
     c_includes = ["HsOpenGL.h"],
     package_deps = ["base"],
     extra_ghc_opts = [],
     extra_cc_opts = [],
     extra_ld_opts = ["-lglu32", "-lopengl32"],
     framework_dirs = [],
     extra_frameworks = []},
 Package
    {name = "GLUT",
     auto = True,
     import_dirs = ["$libdir/imports"],
     source_dirs = [],
     library_dirs = ["$libdir"],
     hs_libraries = ["HSGLUT"],
     extra_libraries = ["HSGLUT_cbits"],
     include_dirs = [],
     c_includes = ["HsGLUT.h"],
     package_deps = ["base", "OpenGL"],
     extra_ghc_opts = [],
     extra_cc_opts = [],
     extra_ld_opts = ["-lglut32"],
     framework_dirs = [],
     extra_frameworks = []},

Thank you for your help,
