The platform package (mcpp SPEC-013) of 32-bit DOS programs built by DJGPP: the row i586-dos-djgpp
as data, its GCC payload, and DOSBox Staging as its runner.

|---|---|
the row: COFF, .exe, 32-bit data model, the execution system dos |
[[platform.define]] |
the compiler: DJGPP's GCC 12.2.0, named by the row's GCC target i586-pc-msdosdjgpp (xim i586-pc-msdosdjgpp-gcc) |
gcc-triple, [platform] toolchain |
| the C library: DJGPP 2.05, the toolchain's own | [platform.layers] |
the runner: dirun places the program and CWSDPMI (the DPMI host) in the directory DOSBox mounts as C: and reads the program's output and status back from files a launcher writes (xim dosbox-staging, dirun) |
[platform.runner] |
The engine knows no DOS: the row, its payload and its runner are this package's. The GCC target a row states is the engine's general mechanism for a cross GCC (mcpp 2026.11.13.1).
C only. mcpp compiles C++ as modules, which needs a GCC with module dependency scanning (14 and later); DJGPP's GCC is 12.2.0, and a C++ target is refused naming that.
Verified. examples/hello, built with mcpp and run under DOSBox Staging 0.83.0 through dirun
0.3.0: its arguments, a file written and read back, status 42 (0.6 s).
