Tcc + Open2x App Libs

[xhyldazhk]

Hi all,

I usually use TCC-arm + Termula2x to do onboard development while commuting. I just installed on my andLinux Open2x to take advantage of its optimizations, and tried replacing the libs i configured for TCC (that if i remember well are the official SDK ones) with the Open2x libs. The result: The executables produced now segfault. Any help on this? Thanks in advance.

Hi, i have to admit i have never used TCC etc. Theres a good chance that the libs are using a conflicting version with those on the gp2x. Have you tried statically linking by passing in '-static' to the linker to see if that helps?

Thats the first thing that came to mind, hope that helps

Thanks Lonewolf... Yes, i've been linking them statically... But i think it could have more to do with the fact that Open2x libs are compiled with soft float emulation or something alike... there is any patch to enable tcc to link with libraries compiled with gcc and soft float emulation?

I've never been able to get TCC working at all, on a MK1 and MK2.. . I'm curious about this as well though, since I plan to switch to Open2x one of these days.

I use this script to build the TinyCC onboard package in a bash environment, like MinGW or native GNU/Linux. Its installed on dev/tcc inside of the SD card.

I have to set up paths in my .bashrc so /mnt/sd/dev/tcc/bin is en the path.

I hope this helps you all.

At least! I made Tiny C Compiler work with the official libs...
You will need:
- The official SDK
- The latest patch to the official SDK
- MSYS with CVS
- wget in your path

This script is easily adaptable to run on other operating system

With this and Termula2x, you can code games on the go...
