Maybe you could look at this C compiler, as it user fasm as a backend
http://freshmeat.net/projects/simplec/?branch_id=44088&release_id=205235 Note: Its not for menuet, but may help ?. |

The direct link is http://iam.gorodok.net/lcc41.zip
It is a C compiler, which translate code to ASM(which can be compiled by FASM). It work in Windows or DOS... It would be interesting to see the "sources of TCC for Menuet translated to Fasm". Can you give a link? |

AFAIK, it work in MenuetOS and with some modification in KolibriOS, but it cannot work with large or 2d arrays and have some problems with includes. Example application is at first post here http://meos.sysbin.com/viewtopic.php?t=519&start=15 PS: Usually "TCC" is http://fabrice.bellard.free.fr/tcc/ BTW, your OS is good. |

Hi,
i posted, in the old meos board, a linker that accepted coff objs and output meos executables with this tool, you could use visual c++ to produce meos executables... but seens the board dont exists anymore, and i cant find it in my sources archives maybe one of the users of that old board downloaded and saved it jmgk |

I think you don't need any extra compiler for MenuetOS. On linux I can use gcc for compiling executable for MenuetOS. I say linux since on Windows (cygwin, mingw) although you should also be able to use gcc, but there the linker doesn't support binary format (I reveal you it can be overcome).
To compile executables for MenuetOs on linux you need to create a linker script for MenuetOS and to implement syscalls of MenuetOS (some inline assembly). Once I tried it out but not with C (it would have been too simple  ) but with Ada. I used the gnat compiler. I implemented the famous EXAMPLE.ASM from the distribution floppy. And it really worked. The original EXAMPLE was 470 bytes while my Ada version 480. Not a big difference, however I didn't optimize everything, so there are pads of many bytes generated by the linker which are still to be eliminated. Maybe with bare C you could reach the size of the hand written code. I guess that a thoroughly written C-code can even be better. Not speaking about the productivity...
Now I've looked for it again to show you the opportunity you might want to exploit. I've made some changes on it, so it can happen that it doesn't want to work now, but the necessary corrections can be done also by you. I reveal that you can do the same with gcc and g++, however in this latter case you will have troubles with virtual functions, but at least there is no problem with inharitance.

I'm developing modification of TCC compiler for MenuetOS. Currenly the main problem is standart library.
Endre There is one more problem with C++ - exceptions. Currently MenuetOS/KolibriOS doesn't support them. |

This is the tool that linked coff files into menuetos programs??? I could never make it work :S
EDIT: by the way... the script to compile menuetos binaries from gcc already has been done a long time ago... Jarek made it, I have a copy in my HD. if you want I can upload it to you (Doom 2, DOSBox, and Quake were ported to MenuetOS with that script)

No offense to Jarek (spideros1), but I think he hasn't posted here in over a year, plus his website is down. So, go ahead and post whatever.

@DC740: I think if Jarek had known the gnu linker a bit more then he wouldn't have written this superfluous program. Even not with MSC. It's however not a script but a simple linker. This job can also be done by the standard gnu linker on linux (see my example), and also on windows. Although in this latter case you have to cut the first 2048 bytes as I remember (you can simply do it with dd). But why should you write an own linker? Nonsense.
@Halyavin: Yes, you're right, but if you know how exceptions/virtual functions/etc. work, then you can write the appropriate functions (library) that the linker could use to resolve the problems when building menuetos executable. It's not a big magic, but needs a bit more work at the beginning. Last edited by Endre on 14 Jul 2006, 19:24; edited 1 time in total |

DC740,
yes, the tool is this one... what problem you found using it? in my tests, it worked so weel, that i was very proud of it
you must remember that it dont have a libc for menuetos, so, if you use basic things like strcpy() and like, you need to code it yourself jmgk |

2Endre:
virtual function requires no run-time support, just link with .rdata* sections (mingw gcc 3.*?). RTTI - too complex & too overheaded for meos. run-time support for exeptions coming soon  |

I don't know whether the first way is feasible. |
