I tried building libpng. Didn't work.

zlib changelog:
Changes in 1.2.3.9 (21 Feb 2010)
- Expunge gzio.c

libpng changelog:
version 1.5.0beta10 [February 25, 2010]
Removed unused gzio.c from contrib/pngminim gather and makefile scripts

libpng 1.5.0 is not out yet although I couldn't find any references to gzio.c in gather or makefile scripts in libpng 1.4.3. Nor did a search find any in the project. Has anyone seen this?

Are you just having trouble building zlib? Is this in any way specific to FreeOrion?

The only references to gzio.c I see in the libpng 1.2.34 project files are in the zlib project. It is there in the source files, though. I haven't examined any later versions.

I updated the FO project and rebuilt it but once I run the exe it crashes almost immediately. It does throw some exception but I can't see it. Is there any log for CTDs? Anyway the compile page said that I should rebuild libpng in the occasion of such CTD. This led to zlib problem.

It starts to compile it and this is what happens.

What version did you have before updating, and were you able to build and run before doing the update?

Run from the command line (cmd.exe) to see text output after crashes.

Depending when the crash happened, there could be something in the standard log files: freeorion.log or ogre.log in C:\Users\Username\AppData\Roaming\FreeOrion

That's one possible cause of a crash. Are you using MSVC 2008? If so, you shouldn't need to recompile zlib and/or libpng; the versions in the SDK should work.

If you're using MSVC 2010 and have never compiled and run freeorion successfully, that might be the issue. The log files or the text of the exception on the command line might help with that.

It looks like there's a problem with the zlib project files then. Try removing gzoi.c from the zlib project (not the libpng project).

Yes. The SDK worked flawlessly.

Ok, that's a good hint.

I'm still trying to find it. Not anymore though.

Looks like there's a problem with content parsing. The most likely cause is trying to read in content files for a different version than what you're running. Try deleting your config.xml. If that doesn't work, make sure your techs.txt is updated to the latest from SVN.

Likely libpng and zlib are unrelated to this crash.

Great. It's working. Again.
