We were doing it like this in the past, only changed to unconditionally pulling in DOSBox cus upstream said it might be necessary. Turns out that the docs build hasn't worked in awhile cus DOSBox doesn't launch without OpenGL available to it. Since the docsless variant is unaffected, DOSBox does only seem necessary when building the docs. Also, fix the docs build by using llvmpipe for OpenGL.

|
|
A fork of Open Watcom: A C/C++/Fortran compiler and assembler suite
|
|
targeting a multitude of architectures (x86, IA-32, Alpha AXP, MIPS,
|
|
PowerPC) and operating systems (DOS, OS/2, Windows, Linux).
|
|
|
|
Main differences from Open Watcom 1.9:
|
|
|
|
- New two-phase build system - Open Watcom can be built by the host's
|
|
native C/C++ compiler or by itself
|
|
- Code generator properly initializes pointers by DLL symbol addresses
|
|
- DOS tools now support long file names (LFN) if appropriate LFN driver
|
|
is loaded by DOS
|
|
- Open Watcom is ported to 64-bit hosts (Win64, Linux x64)
|
|
- Librarian supports x64 CPU object modules and libraries
|
|
- RDOS 32-bit C run-time compact memory model libraries are fixed
|
|
- Resource compiler and Resource editors support Win64 executables
|
|
- Open Watcom text editor is now self-contained, it can be used as
|
|
standalone tool without any requirements for any additional files or
|
|
configuration
|
|
- Broken C++ compiler pre-compiled header template support is fixed
|
|
- Many C++ compiler crashes are fixed
|
|
- Debugger has no length limit for any used environment variable
