I really can't figure out how to compile it as a shared library without modifing the source.
The problem is afaik, that all the api functions are declared in cpp-Files (without extern "C").

Could some clever guy give me a hint how to solve this?

That was also my first approach, but since the definition is in a cpp-file it doesn't works.
At least for gcc/mingw. Since I have no VC++ on my machine, I had no chance trying it with their compiler.

This makefile works for me

Code:


INCZ= -I$(SQUIRREL)/include -I. -Iinclude

SRCS= \
    sqapi.cpp \
    sqbaselib.cpp \
    sqfuncstate.cpp \
    sqdebug.cpp \
    sqlexer.cpp \
    sqobject.cpp \
    sqcompiler.cpp \
    sqstate.cpp \
    sqtable.cpp \
    sqmem.cpp \
    sqvm.cpp \
    sqclass.cpp
sqdll:
  gcc -O2 -shared -fno-exceptions -fno-rtti -Wall -fno-strict-aliasing -c $(SRCS) $(INCZ) -D"SQUIRREL_API=__declspec(dllexport)"
  g++ -shared -s -o squirrel.dll *.o


ciao

Huh, okay I didn't knew that it should be done like this.
On the internet I've read about the 'problem' with libstdc++ in C-DLLs, but somehow I utterly failed to write a working makefile.

Thanks, you helped me alot! :D

Btw. I want to use this for a module system, much like the one by Toji.
In the last time I've already written some modules like a FastCGI interface or a irc client/bot.
