Some notes on compiling on Ubuntu 8.10 64 bit

[mmarshall]

Just FYI:

I had to add #include <string.h> to physfs/File.cpp. Otherwise it complained about strlen not being defined. (This seems to be something with 64 bit linux... I've had to add a number of #include <string.h>'s to some of my own code to compile on 64 bit.)

The configure script didn't check for a number of dependencies. I had to go back and forth between make and apt-get install quite a few times.

Here are the packages that I remember being required that configure didn't check for:

* boost
* SDL_mixer.h
* physfs
* libdevil

(I normally have stuff like this installed, but I just switched to 64 bit on this system and haven't compiled much yet.)

Thanks. All this should be fixed in SVN already. Tido made sure to check all dependencies this time (boost and SDL_mixer not needed in next version). Let us know if you notice something missing.

Code: Select all

AC_SEARCH_LIBS([sqrt], [m], [], AC_MSG_ERROR([Can't LÖVE without C math library]))
AC_SEARCH_LIBS([SDL_Init], [SDL], [], AC_MSG_ERROR([Can't LÖVE without SDL]))
AC_SEARCH_LIBS([Sound_Init], [SDL_sound], [], AC_MSG_ERROR([Can't LÖVE without SDL Sound]))
AC_SEARCH_LIBS([glLoadIdentity], [GL], [], AC_MSG_ERROR([Can't LÖVE without OpenGL]))
AC_SEARCH_LIBS([gluOrtho2D], [GLU], [], AC_MSG_ERROR([Can't LÖVE without OpenGL Utility Library]))
AC_SEARCH_LIBS([alSourcePlay], [openal], [], AC_MSG_ERROR([Can't LÖVE without OpenAL]))
AC_SEARCH_LIBS(
	[lua_pcall],
	[lua lua5.1],
	if test "$ac_cv_search_lua_pcall" = "-llua5.1"; then
		AC_SUBST([INCLUDE_LUA], [-I/usr/include/lua5.1])
	fi,
	AC_MSG_ERROR([Can't LÖVE without Lua])
)
AC_SEARCH_LIBS([ilInit], [IL], [], AC_MSG_ERROR([Can't LÖVE without DevIL]))
AC_SEARCH_LIBS([mng_initialize], [mng], [], AC_MSG_ERROR([DevIL needs MNG]))
AC_SEARCH_LIBS([TIFFOpen], [tiff], [], AC_MSG_ERROR([DevIL needs TIFF]))
AC_SEARCH_LIBS([FT_Load_Glyph], [freetype], [], AC_MSG_ERROR([Can't LÖVE without FreeType]))
AC_SEARCH_LIBS([PHYSFS_init], [physfs], [], AC_MSG_ERROR([Can't LÖVE without PhysicsFS]))

Now that VirtualBox supports 64-bit guests on 32-bit hosts, I can probably start providing a .deb too.

I compiled LÖVE on Fedora Core 9, 64bit. It was overall a simple process but a list with the necessary libraries would still be nice, e.g. in a file called INSTALL. My steps:
* Added include-statement to ./src/physfs/File.cpp.
* Installed SDL_Mixer, missing development packages of SDL, and DevIL.
* Installed PhysFS and copied libphysfs.so (also libphysfs-1.0.so.1) to physfs.so.1 (in /usr/lib64 for 64bit-arch.)
* Recompiled allegro with --disable-asm (only necessary for 64bit-arch).

However, my frame rate appears to be fixed at 6 FPS in games that have more than a few bodies, e.g. wrath, militia defense, and my own tests. The tutorial games all work well, including the collision detection tutorial. I have a geforce 7300 GS, the official nvidia drivers, mesa, and no desktop effects activated. Running vista on the same computer, I experience no lag unless there's 200-300 shapes.

How can I improve my FPS?
