Compiling 3991

[kupferdrache]

thanks, for this quick answer, I have got the latest svn shot

• I have downloaded and installed MSVS 2010 Express
  i got svn
  i got MSVS2010FreeorionSDK
  i got the sources by svn
  i opened .sln File
  I builded the project

but wenn i try to start the game, it chrashes on creating the Mainwindow

the freeorion.log remains emty.

now if I try to start the perbuild freeorion i get following:

2011-04-25 13:43:21,045 DEBUG Client : OpenAL initialized. Version 1.1Renderer SoftwareVendor Creative Labs Inc.

What can I do?

Edit:
I have attached, the logfiles, after rebuild.

You need to delete your config.xml every time you switch between versions. (That is, every time you run a version different from the previous version you ran.)

No in this case, it wasn#t my fault, I have deleted/renamed the config.xml.

The Problem occurs only when building under Win7 systems,but not when using prebuild binaries, then freeorion crashes because wrap_oal.dll is used a worng version or missing. I found a clue in Programming section how to work around, but this should fixed in SDk and/or scource.

The AI seem no more to work in 3991 in Build 3946 the AI was partly working.

...freeorion crashes because wrap_oal.dll is used a worng version or missing.

Do you still get the error messages about techs being missing or there being empty categories after replacing the dll? I was based my suggestion to delete config.xml on those messages, which shouldn't have anything to do with the sound DLL.

The AI seem no more to work in 3991 in Build 3946 the AI was partly working.

To diagnose that, please post the AI log files (if present) from after running a game in which the AIs don't work. If there are no AI log files created, then post the server log file (freeoriond.log).

This may also be related to the missing tech error messages, if they're still occurring.
