Still can't compile C++ FFI example by cl.exe
The example from page http://dynamo.iro.umontreal.ca/~gambit/wiki/index.php/Compiling_Gambit_softw... compiled successful. I have change it.
<<<foo.cpp>>> int cpp_bar(char* text) { return 0; }
<<<foo.h>>> #ifdef __cplusplus extern "C" { #endif int cpp_bar(char* text); #ifdef __cplusplus } #endif
<<<foo-main.scm>>> (c-declare #<<end-of-c-declare #include "foo.h" end-of-c-declare ) (define bar (c-lambda (char-string) int "cpp_bar"))
Then compile it: gsc -link foo-main cl -Fefoo-main.exe -nologo -Oityb1 -MT -D_CRT_SECURE_NO_DEPRECATE -c -I"C:\gambc\include" -I"C:\gambc\lib" -D___SINGLE_HOST -D_WINDOWS "foo.cpp" "foo-main_.c" "foo-main.c" cl -Fefoo-main.exe foo.obj foo-main.obj foo-main_.obj C:\gambc\lib\libgambc.lib Kernel32.Lib User32.Lib Gdi32.Lib WS2_32.Lib /link /subsystem:windows

What is wrong here? Does anybody know where I can get workable example of C++FFI under windows? Could be great if the wiki will have some examples how to build and app with C++ FFI under different platforms.
