the-great-escape-in-c's Issues

26/32-bit neutral build... isn't (RISC OS)

I saw a GtEscape build crashing on ArcEm, Arculator and ArchiEmu but only when configured for ARM2, not ARM250. In fact it locked the virtual machines solid. After some digging I found that the OSLib that I link against isn't 26/32-bit neutral. The 32-bit version uses MRS instructions and they somehow work on emulated ARM250's, but not on emulated ARM2's.

Add full screen mode (RISC OS)

Add a full-screen mode to the RISC OS build. This won't multitask and will perhaps speed up the game on ARM2 to an acceptable level.

Package modern CLib with GtEscape (RISC OS)

We now build against GCCSDK's SharedCLibrary support. This requires a 'new' SCL, which will have to be supplied alongside !GtEscape for older systems.

Add 8-bit sound system support (RISC OS)

We currently only support sound on systems fitted with 16-bit sound. Try to work out how to make it work on 8-bit systems too.

License of the source code

Hi,

The headers of the source file say "It is free software provided without warranty in the interests of education and software preservation.". I'm not sure what this exactly would mean.

Is it compatible with the MIT or GPL license?
How did the translation took place? There is a conversion document but I'm not sure if all the code was just recreated or if it's more like a disassembly? If it was more like a disassembly, can it become free software? Did the original authors maybe give their consent?

Kind regards

CMake build

Complete the CMake build work. In particular CMake builds on Windows will need to be supported.

build on Linux

I tryed to build on Linux.
Both running:
The-Great-Escape-in-C/platform/generic$ gcc -I../../include sdlmain.c -o tge
or
The-Great-Escape-in-C/platform/generic$ make -f SDL.mk build
it stop with this error:
