Title: Linker errors when building fs2_open
Post by: ed on October 28, 2007, 09:16:15 am

First of all, some introductions. I'm (hopefully) going to be helping out RazorsKiss on the Fringespace mod (http://fringespace.org/index.php), mainly doing features/gameplay coding - I might also have a look at the multi-player network code.

Anyways, I have been trying to get the code and build it so I can have a play around/look at the code. I'm using Visual Studio 2005 Pro.

• I got the code of CVS (using these instructions http://www.hard-light.net/wiki/index.php/Getting_the_FreeSpace2:_SCP_Source_Code).
• Opened the VS2005 .SLN file.
• Built the solution.
• Got these linker errors:

I cant seem to find any function definitions for these functions in code - am I missing a library or something?

add the following files to the 'code' project

• network/chat_api.h
• network/chat_api.cpp
• network/multi_pxo.cpp
• network/multi_pxo.h

Sweet, builds now! How come those files aren't part of the project?

Cause they were added only a week or two ago by a coder who (I presume) uses VC6 and no one had updated the 2005 project file.

Yeah, I only use VC6 (under Wine, since I don't run Windows) so those are the only project files that I can update.
