Myst 3 on Android

Hi all,

I am trying to run Myst 3 with ResidualVM on Android. I copied all the files listed at http://wiki.residualvm.org/index.php?ti ... les#Myst_3, but ResidualVM does not find the game. I own the DVD French version of myst 3 and I am wondering if the file list is the same as for the CD version.
Also, do I have to copy all the files in the same directory or do I have to keep the files in their respective directories (Data, M3Data and directory therein)?

Thanks for your help.

The versions I compiled (in the other thread) have the myst 3 engine disabled in the configuration
If you want to help develop on myst3 (on PC or Android), I suggest you take my source tree, compile it with myst3 support, and see what happens.
I don't think I own myst 3, so I cannot launch the game to check what it looks like.

Some simple compilation steps can be found in the other thread.

Or just drop by on IRC (irc.freenode.net, #residualvm) and I can help you compile it.

Thanks for your answer.

I am trying to compile a version with the myst 3 engine, but have an error with gl.h:
../engines/myst3/gfx.cpp:42:19: fatal error: GL/gl.h: No such file or directory

locate gl.h gives:
...
/usr/include/GL/gl.h
...

So I don't understand why the file couldn't be found.
Any idea?

The android build doesn't look at your system headers.
Check build/android-toolchain/sysroot/...
I would give configure the right options to use TinyGL instead of OpenGL (which probably won't compile unmodified anyway).

I *think* it's --disable-opengl, but can't check atm.

Actually, --disable-opengl won't do anything, I have to add --disable-opengl-shaders:

Code: Select all

3754	android)
3755		if test "$_opengl_shaders" = yes; then
3756			_opengl=yes
3757			_opengles2=yes
3758			LDFLAGS="$LDFLAGS -Landroid-toolchain/sysroot/usr/lib"
3759			LDFLAGS="$LDFLAGS -lGLESv2"
3760		fi
3761		;;

But with --disable-opengl-shaders, the myst3 engine cannot be built (./configure results in Myst 3 engine skipped)...

By the way, what do you mean by "Check build/android-toolchain/sysroot/..."?
If it's the point, there is gl.h in build/android-toolchain/sysroot/usr/include/GLES/, but no glu.h.

I'm sorry but I'm not familiar with OpenGL or TinyGL.

Did anybody test Myst 3 on android?

No. There are four contributors to the Android port of ResidualVM, but nobody is testing myst3 at the moment.
I just looked through gfx.cpp, it doesn't do terribly complicated things, so it should be fairly simple to port to openGL ES.
I won't have the time for it, though.

A stopgap measure could be to use regal in the meantime.
It converts the old-style opengl into new-style for you.

Ok, thanks again.
I'll have a look at regal, but I don't think I'll have the time now to test it with Residual.
