OSX: GLUT window never appears - c++

Question

I'm trying to run ORTS on my Mac for a school project. It was ostensibly written to be cross-platform, but I don't know if it was ever properly tested on OSX. After a great deal of difficulty, I managed to get it to compile, but it still doesn't quite work.
When I run the ortsg application, which is the OpenGL graphical interface, the terminal output indicates that the game starts up, loads its assets and runs correctly. However, the actual game window never appears. The only possible indication of any problem is the following message:
2011-11-23 16:52:33.513 ortsg[4565:107] GLUT Warning: glutInit being called a second time.
Other than that message, all of the output is exactly the same as what I see when running on my school's Slackware Linux machines, where the game runs fine. (Unfortunately it's rather inconvenient for me to do my work on those machines, hence my attempts to run it on OSX.) I can get rid of that warning by commenting out a call to glutInit in apps/ortsg/src/ortsg_main.C, which doesn't seem to introduce any other problems, but the game window is still never shown.
I can't seem to find reports of anyone having similar problems on Google. I don't expect anyone on SO will be intimately familiar with ORTS, so my questions are as follows:
Are there any common scenarios which might cause a GLUT window to not appear, particularly on OSX?
Does GLUT provide any facilities for debugging such problems?
Edit: As requested by JimN, here is some of the GLUT initialization code...
// From apps/ortsg/src/ortsg_main.C
int main(int argc, char **argv)
{
char mydir[81];
getcwd(mydir, 80);
glutInit(&argc, argv);
chdir(mydir);
// ...
}
// From libs/gfxclient/src/GfxInit.C
void glutVisibilityDebug(int state)
{
if(state == GLUT_VISIBLE)
cout << "Window is visible" << endl;
else if(state == GLUT_NOT_VISIBLE)
cout << "Window is invisible" << endl;
else
cout << "Window state unknown";
}
void GfxModule::init_GLUT_window()
{
cerr << "INITIALIZE GLUT WINDOW" << endl;
GfxGlutAdaptor::set_client(this);
glutInitDisplayMode(GLUT_RGBA | GLUT_DOUBLE | GLUT_DEPTH | GLUT_ALPHA);
// the window starts near the upper left corner of the screen
glutInitWindowPosition(opt.win_x, opt.win_y);
glutInitWindowSize(opt.win_w, opt.win_h);
// Open a window
glutCreateWindow(opt.title.c_str());
// Register the splash as the draw routing until
glutDisplayFunc (GfxGlutAdaptor::splash);
glutVisibilityFunc(glutVisibilityDebug);
if (opt.full_screen) glutFullScreen();
}
I added the glutVisibilityDebug function to see if I could determine what GLUT thinks the window's visibility state is, but none of my debug statements are ever printed. Something else just occurred to me which might help debug this. I tried at one point to replace glutDisplayFunc with a function which just printed "glutDislplayFunc called" to stderr. I noticed that the text was only printed when I quit the application.

Answer 1

I downloaded the daily snapshot from 26/11/2011, and then installed all dependencies using brew on my Mac.
Executed export OSTYPE=DARWIN followed by make init and make. There were several compilation problems which I fixed on this makefile:
# $Id: makefile 10648 2011-10-06 15:46:07Z mburo $
#
# This is an ORTS file (c) Michael Buro, licensed under the GPL
# This make file works for systems which use gcc
#
# - shell variable OSTYPE must be set in your shell rc file as follows:
#
# if LINUX matches uppercase($OSTYPE) => Linux
# if DARWIN matches => Mac OS X
# if CYGWIN matches => Cygwin (gcc on Windows)
# if MSYS matches => MinGW (gcc on Windows)
#
# check that value with echo $OSTYPE and set it in your shell resource
# file if above words don't match. Don't forget export OSTYPE when using sh or bash
#
# I use: OSTYPE=`uname`
#
# - ORTS_MTUNE = i686 athlon-xp pentium-m etc.
# if set, -mtune=$(ORTS_MTUNE) is added to compiler options
#
# - set GCC_PRECOMP to 1 if you want to use precompiled header files (gcc >= 3.4)
#
# - adjust SDL/X paths if necessary
#
# - for non-gcc compilers try -DHAS_TYPEOF=0 if typeof causes trouble
#
# - make MDBG=1 ... displays the entire compiler/linker invocation lines
#
# - make clean removes make generated files
# - make cleanobj removes all .o files
#
# - make [MODE=dbg] compiles targets in debug mode (no STL debug!)
#
# - make MODE=opt compiles with optimizations
#
# - make MODE=bp compiles with bprof info
#
# - make MODE=gprof compiles with gprof info
#
# - make MODE=stldbg compiles optimized stl debug version
#
# - make <app> creates application bin/<app> (omit prefix bin/ !)
# use periods in <app> in place of slashes for applications
# within subdirectories (e.g. "make rtscomp06.game2.simtest")
#
# - make list displays a list of all registered applications
#
# - make init creates necessary dep+bin+obj directories and links
#
# - make creates all applications
#
# - shell variable ORTS_MODE defines the default compile mode
# if not set, the passed MODE= parameter or dbg will be used, if MODE is not passed
# otherwise ORTS_MODE will be used
#
# issues:
#
# - all include files are used (only using library includes would be better)
#
# new:
#
# applications and libraries can now name their individual external library dependencies
# (libs + headers)
# see: apps/*/src/app.mk and libs/*/src/lib.mk, esp. libs/gfxclient/src/lib.mk

Then some changes I had to do manually, to fix errors like:
sr_bv_math.cpp:561: error: ‘isnan’ was not declared in this scope
Edit the file trunk/libs/pathfinding/dcdt/sr/src/sr_bv_math.cpp and right after the cmath include, declare isnan as extern:
#include <cmath>
extern "C" int isnan(double);
That compiled the binaries, but then I had to also download orts_data.tgz to run the applications.
Well, running ortsg for the very first time failed, reporting:
texture size = 64X64
REMARK: can't open file: testgame/ortsg/terrain.tga
REMARK: can't open file: testgame/ortsg/noise.tga

REMARK: closing connection
REMARK: !!! already closed
REMARK: ~IO_Buffer called
Even though the files are there. So I KILLED the application and tried it again:
2011-11-27 01:51:02.947 ortsg[390:903] GLUT Warning: glutInit being called a second time.

Abort trap
The first line of the error might be familiar to you. Even though the app was killed, something seems to be left hanging somewhere, and the only way I found to bypass the error and have a clean run of the application was rebooting my computer.
It seems this application has issues on Mac OS X and need immediate fixing. I suggest you install a Linux VM, or even a Windows VM inside your Mac to be able to run orts, if you really have to use it.
