[Tinycc-devel] [BUG] 0.9.28.pre - Cannot link due to : undefined symbol 'main'

[david . koch]

Hi,

using TCC here and there, maintaining a "personal" copy here :

https://github.com/Kochise/tinycc_win32

I was working on compiling GLFrontier with TCC, yet just got :

tcc: error: undefined symbol 'main'

I made some slight changes to the code (like adding Christian Jullien's dirent 
for TCC).

You can find the "fork" here :

https://github.com/Kochise/GLFrontier-win32

1- clone the two repos into the same folder
2- go to 'GLFrontier-win32\src'
3- run 'Makefile-tcc.bat'

You'll get something like :

'GLFrontier-win32\src\lib\SDLmain.lib' contains an entry point to 'main'

Yet is not recognized as a library.

'GLFrontier-win32\src\lib\libSDLmain.a' contains an entry point to 
'console_main'

Both contains an entry point to 'WinMain@16', but this is "handled" by SDL.

So, I'm running out of idea how to get this linked.

Your thought ?
