mwccwrap

Command-line wrapper for CodeWarrior compiler plugin DLLs.

Background

CodeWarrior for PlayStation shipped its C/C++ compiler only as an IDE plugin DLL (cc_mips.dll) — no standalone mwcc command-line executable was ever provided for the PS1 target. Later CW MIPS targets (PS2, PSP) did ship CLI tools (mwccps2.exe, etc.), but PS1 never got one. A similar gap exists for CW Wii 1.2, where the only available installer is truncated and missing mwcceppc.exe, while ppc_eabi.dll is intact.

mwccwrap fills this gap. It builds a Win32 CLI host (mwccwrap.exe) that loads a CW compiler DLL and drives it through the CW plugin lifecycle, plus replacement DLLs that implement the API callbacks the compiler DLL imports. This makes it possible to use these compilers from the command line and from build systems, enabling decompilation projects and other workflows that need reproducible builds with the original compiler.

For usage on Linux or macOS, use wibo (a lightweight Win32 userspace emulator) or Wine.

Supported compilers

Platform	DLL	Versions
PlayStation	cc_mips.dll	CW PS R3, R4, R4.1, R5, R5.2
GameCube	ppc_eabi.dll	CW GC 1.1 through 2.7

Building

Requires an i686-w64-mingw32-gcc cross-compiler (MinGW-w64).

make          # builds mwccwrap.exe and shim DLLs
make clean    # remove build artifacts

Build outputs

File	Description
mwccwrap.exe	CLI host executable
PluginLib2.dll	CW API shim for 1997-era DLLs
PluginLib3.dll	CW API shim for 1998-2005-era DLLs
ASINTPPC.DLL	Mac OS Toolbox API shim

Usage

# Basic compilation (requires cc_mips.dll or ppc_eabi.dll in cwd)
wibo ./mwccwrap.exe -o output.o input.c

# Specify compiler DLL explicitly
wibo ./mwccwrap.exe -dll /path/to/cc_mips.dll -o output.o input.c

# Common flags
wibo ./mwccwrap.exe -O2 -sym on -lang c -I include/ -D MY_DEFINE -o output.o input.c

# See all options
wibo ./mwccwrap.exe -help

Runtime requirements

A compiler DLL must be available either:

• In the current working directory (cc_mips.dll or ppc_eabi.dll), or
• Passed explicitly via -dll <path>
