I tried compiling a C program compiled by Gambit C. My compiler is Visual C++ 2010 Express Edition. I'm getting this error: "unresolved external symbol ____G__20_h". I included the steps I did to create the VC++ project below. Please point out any mistakes. Thanks. -Fiel

Here are the steps I took to create the Visual C++ project:

1. Project-wide settings (project type is unmanaged win32 console application):

- Added "C:\Program Files (x86)\Gambit-C\v4.6.0\lib" and "C:\Program Files (x86)\Gambit-C\v4.6.0\include" to additional include directories. "include" is needed for including "_gambc.c" in gambit.c below. - Added "C:\Program Files (x86)\Gambit-C\v4.6.0\lib" to additional library directories. - Added "___APPLICATION" to C preprocessor definitions. This causes main() to be defined. - Added "ws2_32.lib" and "libgambc.lib" to additional libraries.

2. Added file "h.scm" to project. Added custom build tool to compile "h.scm" to "h.c". Custom build tool command line for h.scm: "c:\Program Files (x86)\Gambit-C\v4.6.0\bin\gsc.exe" -c "%(FullPath)". 3. Added file "h.c" to project. Set it to be compiled as C code. Turned off usage of precompiled headers. 4. Added file "gambit.c" to project. Set it to be compiled as C code. Turned off usage of precompiled headers. 5. Contents of h.scm: (display "hello") (newline) ----- 6. Contents of "gambit.c": #include "_gambc.c" -----
