This is a blantant ripoff of [Wunderboy's sandbox page] - I'm using it to log the many things I had to fix to get the orange box sdk to compile under linux. I'm certainly not an expert, so this isn't a tutorial, but instead its a monologue - if you're having trouble doing the same thing, maybe this can be of help. If I come up with anything else thats worth putting in here, I'll do so.
Building the Orange Box server dll in Linux
I dual-booted Ubuntu onto my older XP machine. I had no particular reason to choose Ubuntu over anything else, but I liked the sound of it.
I followed every guide I could find online, installing xerces-c 2.6 and eventually finding a compiled version of G++-4.1 (the orange box makefile says it prefers 4.1, although all the tutorials I could find online, which AFAIK assume Ep1 SDK, say you need 3.4). I was good to go. Navigate to the linux_sdk folder in a terminal window, and type make.
The first error was that all the makefiles had windows line endings (\r\n) rather than linux ones (\n). Unfortunately, this wasn't at all obvious in gedit (the default text editor), so I spent a fortnight trying to work out why the whole thing just wouldn't work. In the end I installed nedit, and opened each makefile with that, as it showed up the \r character (carriage return) on the end of each line as a nice obvious <CR>. I removed these manually (apparently this could have been done by running dos2linux on each file in turn, but this only took 5 minutes)
This was great, it actually started building several files before failing. Given what I'd been through with the newline issue, this was practically bliss. It had actually started. I had some error messages that i think were the compiler trying to find some xerces-c v2.8 files, so I installed xerces-c 2.8 alongside the 2.6 I had already.
It then seemed to happily build VCPM, but trying to run it, I kept getting an 'unable to find shared library: libxerces-c.so.28' no matter what I tried. Eventually, online I found that first typing this command: export LD_LIBRARY_PATH=/usr/lib/xercesc worked wonders, and it actually started to try to build my mod. Woot! Note that this would need to be done every session before the mod would build.
It quickly failed when it couldn't find Makefile.ServerSDK_ReleaseWin32 ... this was evidently because the wrong build configuration was set by the MOD_CONFIG parameter. I looked at the files that had been created in the linux_sdk folder, and one of them was Makefile.Server(HL2MP)_ReleaseWin32 ... so I changed the macro in my makefile to MOD_CONFIG=Server(HL2MP)_ReleaseWin32
Now it started trying to build the server, but fails because of a syntax error: 'Syntax error: "(" unexpected' I guessed that this was down to the brackets in the filename. Hoping this wouldn't screw anything, I renamed the file and the MOD_CONFIG param, just removing the brackets, and tried again. Looks like this was right on, it goes a little further.
G++ complains of no input files, then there's a lot of directories not found... then its ultimately stopped by an error thats something to do with ai_activity.o.
I remembered seeing something like this somewhere on the wiki, turns out it was the script at the bottom of Wunderboy's sandbox page. http://developer.valvesoftware.com/wiki/User:Wunderboy/sandbox
While this no doubt fixed other problems, unfortunately after I ran the script, I was still getting the ai_activity.o error. Looking at it again, its probably just cos its the first file alphabetically in the server project.
I tried manually editing the generated server makefile, replacing ../../ with ../ in all the paths that looked like the ones that were "not found" - but this produced permission denied errors instead. Looking at the command that produces all the error message, I can make the No Input error stop if I remove all parameters except for the .o filename and the source filename, but clearly this causes lots of undefined errors. I had to try running this command manually, to see what parameter was messing it up.
The problem appeared to be the include directories. Specifically, in the INCLUDES define of Makefile.ServerHL2MP_ReleaseWin32, there were some seperated like this: -Iinclude1 -Iinclude2 -Iinclude3, etc, and some seperated like -Iinclude1;include2;include3 - if I changed this second type to match the first, then it definately noticed the .cpp source file. However, there were loads of errors with ai_activity.cpp, so it still fails on the first file.
The list of errors is actually longer than the terminal will show, but i saw several "no such file or directory" errors fly past, and some .h filenames, then I end up with what appears to be a list of every ACT_ activity definition not being defined. By commenting out all of the ADD_ACTIVITY_TO_SR lines (which make up virtually all the file), I was able to see the earlier errors: lots of undefined (mostly member) variables in baseflex.h, basecombatcharacter.h, player.h, ai_basenpc.h, etc. Something's seriously screwed.
If it wasn't finding a whole bunch of included headers, I figured the include directories had to be messed up. So I changed the INCLUDES define I mentioned just above, replacing a bunch of ../../ with just ../ - giving me this:
INCLUDES=-I../common -I../public -I../public/tier0 -I../public/tier1 -I./ -I../game/shared -I../game/server -I../utils/common -I../game/shared/hl2 -I../game/server/hl2 -I../game/server/hl2mp -I../game/shared/hl2mp -DNDEBUG -D_USRDLL -D_CRT_SECURE_NO_DEPRECATE -D_CRT_NONSTDC_NO_DEPRECATE -DGAME_DLL -DVECTOR -DPROTECTED_THINGS_ENABLE -Dsprintf=use_Q_snprintf_instead_of_sprintf -Dstrncpy=use_Q_strncpy_instead -D_snprintf=use_Q_snprintf_instead -DHL2MP -DHL2_DLL -DVERSION_SAFE_STEAM_API_INTERFACES
and - WOAH - its building! This is a very slow process, even compared to a windows build. Eventually, I get errors in the achievement management code.
I'm stuck with these for now.
