[Mingw-users] Mixing mingw as compiler with Labwindows/CVI as linker

[Frédéric L. <F.L...@hi...>]

Hello,

I was trying to do some unsual things (using mingw as a compiler and using Labwindows/CVI as a linker) and, as I would expect, strange things happened.
I'm doing this just because it's more convenient if I can make it work well. I could avoid, but... Anyway I want to try ;)

For those who don't know, Labwindows/CVI is some kind of proprietary IDE provided by National Instruments.

All that stuff is related to building a "Windows graphical application".

Here are some messages I get from that CVI at linking time:
  Undefined symbol '___chkstk_ms' referenced in "some_file.c".
  Undefined symbol '___main' referenced in "Main.c".

Doing some (many in fact) searches on the web gave me some solutions:
- use "-mno-stack-arg-probe" at compile time
- define "int __main(void) { return 0; }"

Here are my questions:
- is this the only way to solve my problem ?
- should I worry about potential future problems using the presented solutions ?
- are there some hidden problems I've not already discovered ?
- is this the good way to solve my problem, or is there some other way which are more... nice/beautiful/clever ?
- why such errors ? My guess is that libgcc has to do something with those errors, which may rise another question "is it possible/wise to avoid this dependency ?".

The most magical solution is to define a __main function. That one is quite... surprising I'd say.

I'm not a C/gcc/crt/kernel guru but I'm aware of some of the processes hidden. Feel free to provide links if you don't have time to give a full explanation.

Thanks in advance.

PS: did I already mention that I could just do linking using mingw but it's just not as practical as I would like ?
