Compiling on mac os 10.5 intel

Postby macghost » Mon Apr 12, 2010 4:20 pm

So I've been following Vega Strike for a while now, but am compiling from SVN for the first time. This isn't the first program I've compiled and I've also been a linux user for a while. The wiki cautioned that this would be considered difficult but I had no idea what I would be up against.

I checked out version 12760 source and data and followed the instructions here: http://vegastrike.sourceforge.net/wiki/ ... ile_on_OSX

- I already had SDL installed via MacPorts
- My OS is 10.5.8 and comes with OpenAL via apple

I soon discovered that the built-in GCC was not up to the task (giving errors with the templates in units.cpp).I Upgraded GCC and G++ to 4.4 via macports. This took a while. When this was done I next discovered a errors in the aldrv/ files. After some research I discovered that this was because Apple's OpenAL header is broken (so is the one from MacPorts) and will not work with C++. The fix is to edit the header (yikes) and replace all occurances after the first of "ALCvoid" wth "void". That done, I corrected a few more mistakes with my configuration and vegastrike compiled and linked successfully. The program now runs but segfaults early on with an error reading units.csv, and now I'm stumped. Any suggestions?

- I have uploaded config.log as an attachment.

- The command used to run configure (from the file intel-mac-conf.sh) is this (may be of value to other mac users):
./configure CC=/opt/local/bin/gcc-mp-4.4 \
CPP=/opt/local/bin/cpp-mp-4.4 \
LDFLAGS=-L/opt/local/lib \
CPPFLAGS=-I/opt/local/include \

--enable-macosx-bundle

- I also edited part of the configure script to help find the right libraries. I had some trouble because this part of the script was overriding arguments I passed by hand.

f test "x$is_macosx" = "xyes" ; then

Please recompile with debugging symbols (if you didn't build with debugging symbols), and run vegastrike through gdb.

When it segfaults, and shows the gdb prompt (gdb), type "bt" and attach the resulting output - it will help a lot in figuring out what the problem is.

Santo Buffer Underflow!

That code is evil to unimaginable levels!

Whenever I have the repo at hand (in a writable fashion) I'll correct, commit and post. Thanks for the backtrace :D

(I bet this is the same bug that has been hauting windows testers of the newest binary - thing is, getting a backtrace in windows is a lot harder :( )

Attempt to call ReadFull on a bad file units.csv


Yes, I've seen this on Windows and Linux as well, but it doesn't segfault there.

Some people have complained of crashing binaries - not sure which version.

@macghost: Anyway, I committed a fix yesterday (or was it the day before?) - so if you want to try again you may :)

The fix works. My first test immediately crashed, which is a fault of what I did to get it to compile but indicitave of another problem. I un-defined NV_CUBE_MAP - which must be defined or causes assert(false); in gl_state.cpp at line 71.

With NV_CUBE_MAP restored it won't compile in gl_state.cpp because on the mac OpenGL GL_TEXTURE_CUBE_MAP_EXT doesn't exist. You have to use GL_TEXTURE_CUBE_MAP instead.

To get it to compile I had to go into the source and remove " _EXT" from following:

GL_TEXTURE_CUBE_MAP_EXT
GL_TEXTURE_CUBE_MAP_POSITIVE_X_EXT
GL_TEXTURE_CUBE_MAP_NEGATIVE_X_EXT
GL_TEXTURE_CUBE_MAP_POSITIVE_Y_EXT
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y_EXT

There was a crash when the program tried to load a file called mac.technique. I had a look at some of the techniques files and duplicated default.technique as mac.technique. This may be a configuration program. I haven't compiled vssetup and my hand-editing of the config file is likely to be problematic.

I have a working main menu!
Launched a new campaign... seems to be working. And I have an in-station view with blinking lights! But it looks like my ship didn't render right. On clicking launch it's very slow when anything is on the screen, and the planet is very messed up. This is probably due to my shit macbook intel graphics. But it runs.

WOW! Congratulations!
This is really good news! I thought it was going to take a lot more work to get svn head to compile for MACs.
Could you summarize the needed changes formally?
Klauss, are you on it?, or should I try to commit these changes?

The new vsfilesystem.cpp in r12763 gives the following: in stderr, instead of
Code: Select all
Attempt to call ReadFull on a bad file units.csv
Only read 0 out of -1 bytes of units.csv
!!! ERROR/WARNING VSFile : on ReadFull : Unspecified error (maybe to document in VSFile ?)
'import site' failed; use -v for traceback


now I get just

Code: Select all
Attempt to call ReadFull on a bad file units.csv
'import site' failed; use -v for traceback


These are on Windows and Linux BTW; the older stderr output is from r12742

I have no experience with autoconf on UNIX. I had to hand-edit the configure file but I will see what I can do.

in the OpenGL headers, is the change from GL_TEXTURE_CUBE_MAP_EXT to GL_TEXTURE_CUBE_MAP something that will work on other systems' versions of GL? Or is it something we would have to check for?

Probably something that will work universally; my guess; as "_EXT" stands for "extension" and probably dates back to prehistoric times, when cube-maps were something so new that there was no official support for them in openGL. But I'll let Klauss do the final pronouncements.

I'll make the relevant headers check for existence of GL_TEXTURE_CUBE_MAP first, that would work on all platforms and be self-adaptable, so we don't have to tinker with configure and the likes.

About the slowness, that's why there was a mac.technique, macs have weird sweet spots, even though they supposedly use NVidia GPUs. Thing is, without a dev (a graphics dev) able to write the shader variants for the macs, I'm not sure how to handle the issue.

You might try using one of the lower-end techniques for mac.technique instead - say... fixed.technique (or fixedgl.technique). That will be a serious hit on graphics quality, but at least it will be usable.

I swapped in fixedgl and the planet is now playable. Ships render correctly now also. There's a massive framerate hit (like from over 60 to less than 10) as soon as the mining base is visible. Haven't tested it more than that. My macbook is one of the older ones with intel graphics so it basically can't do shaders.

fixedgl is no shaders.

You could try fixed, which uses shaders (but does nothing fancy). If it works (I'm not sure how much shader support your intel board has), it's faster because it's a single pass technique (compared with fixedgl which has to do many passes to get the same results).

fixed doesn't need a lot - a GeForce3 could handle it. Technically speaking, it doesn't use shaders, it uses "register combiners" - so give it a try.

fixed5 is like fixed but supports less lights (so it's faster).
