getHeader doesn't find a header

[mantielero]

While looking for a workaround for issue #257, it looks like getheader might not be managing well header files with symbols like _:

I have the file occt_wrapper.nim:

# nim c -d:Geom2dCartesianPointStd occt_wrapper
import nimterop/[build, cimport]

static:
  cDebug()                                                # Print wrapper to stdout

cIncludeDir("/usr/include/opencascade")

# The following should create the variables: "Geom2d_CartessianPointPath" 
# and "Geom2d_CartessianPointLPath"
getHeader( "opencascade/Geom2d_CartesianPoint.hxx", altNames = "TKG2d", outdir= "/usr/lib" )

# Checking if nim was called with "-d:headerStatic"
when not isDefined(headerStatic):
  c2nImport(Geom2d_CartesianPointPath, recurse = true, mode="cpp", dynlib = Geom2d_CartesianPointLPath)       # Pass dynlib if not static link
else:
  c2nImport(Geom2d_CartesianPointPath, recurse = true, mode="cpp")

but when I compile:

nim c -d:Geom2dCartesianPointStd occt_wrapper

I get the error in the getHeader line:

/home/jose/.choosenim/toolchains/nim-1.2.6/lib/system/fatal.nim(49, 5) Error: unhandled exception: /home/jose/.nimble/pkgs/nimterop-#head/nimterop/build/getheader.nim(506, 16) `Geom2dCartesianPointPath.len != 0` 
Header opencascade/Geom2d_CartesianPoint.hxx not found - missing/empty outdir or -d:Geom2dCartesianPointStd -d:Geom2dCartesianPointGit -d:Geom2dCartesianPointDL -d:Geom2dCartesianPointConan or -d:Geom2dCartesianPointJBB not specified [AssertionError]

I have tried using the header name: /usr/include/opencascade/Geom2d_CartesianPoint.hxx and I get the error:

Header /usr/include/opencascade/Geom2d_CartesianPoint.hxx not found - missing/empty outdir or -d:Geom2dCartesianPointStd -d:Geom2dCartesianPointGit -d:Geom2dCartesianPointDL -d:Geom2dCartesianPointConan or -d:Geom2dCartesianPointJBB not specified [AssertionError]

but that file obviously exists.

I tried this with SDL_version.h and libSDL2.so and it worked for me. I suspect it has to do with you setting outdir = "/usr/lib". I'll recommend simply setting it to getProjectCacheDir("opencascade") or currentSourcePath.parentDir() and retrying.
