when i try to static link sfml-system-s.lib and sfml-window-s.lib it runs this error:

Please help as i don't know what the problem is because it works when i dynamic link them and no SFML_DYNAMIC is not defined.

First off, are you compiling with /MT or /MD?

is this a mistake in the project file?

No, it's a stupid thing from Code::Blocks

I've tried many different versions of Code::Blocks, and in each the .inl files were *not* compiled by default. I could not even change the option, for users like you.
Unfortunately you have a version of Code::Blocks that *do* compile .inl files by default.

Remember if you are doing static libs, you need to link in the dependencies manually!

Laurent, maybe this could be handled automatically with a post-build script for the static targets?

The last time I tried I failed to make Code::Blocks execute an automatic post-build script.

Laurent · « **Reply #3 on:** July 05, 2009, 06:01:09 pm »

Yes I'm using 8.02. But other users of 8.02 had their .inl files compiled :?

Btw, do you planing on compiling 1.6/2.0 (which ever is next) with MinGW/GCC4.4.0 ? It's officially supported now *wink* *wink* *nudge* *nudge*

I haven't tried, but I'm 99% sure it will compile fine. Don't forget that it already compiles on Linux with gcc 4.4.x

It's compile fine on GCC 4.4.0 TDM-1 and link external dependencies too.

Last svn SFML2 http://phoenix.tweak.free.fr/SFML2.zip

I use a batch script

Code: [Select]

@echo off
set mingw=C:\MinGW
set sfml="c:\SFML\SFML2"
set dest=C:\MinGW
set cb="%PROGRAMFILES%\CodeBlocks"
set PATH=%PATH%;%cb%

codeblocks -na -nd -ns --build sfml-network.cbp
codeblocks -na -nd -ns --build sfml-system.cbp
codeblocks -na -nd -ns --build sfml-window.cbp

recompiled SFML using the project files, then ran your bat file

I thyink the script already does it

Code: [Select]

codeblocks -na -nd -ns --build sfml-audio.cbp
codeblocks -na -nd -ns --build sfml-graphics.cbp
codeblocks -na -nd -ns --build sfml-main.cbp
codeblocks -na -nd -ns --build sfml-network.cbp
codeblocks -na -nd -ns --build sfml-system.cbp
codeblocks -na -nd -ns --build sfml-window.cbp

Laurent, it might be good to include this script in the Windows SDK.

Yep, it looks interesting, I'll see what I can do with it

Laurent · « **Reply #9 on:** July 07, 2009, 11:34:52 pm »

Phoenix, do you mind if I use your script, and maybe modify and add it to the repository?

Phoenix · « **Reply #10 on:** July 08, 2009, 10:30:44 pm »

You can modify it and add to repository, there isn't problem.

Laurent · « **Reply #11 on:** July 10, 2009, 03:36:58 pm »

Thanks

I added it to the repository (trunk), together with ar.exe and the required external libraries. So that the only thing required before running the script is that codeblocks.exe is accessible (in the PATH).

The script now builds every configuration (debug/release static/dynamic) and properly copies back the static libraries to lib\mingw after modifying them.

I guess my 3.4.5 libraries are compatible with the new version of MinGW (4.4.x); maybe someone can confirm that.
