I have successfully built/linked MATLAB mex files on Windows using GCC
in Cygwin. Unfortunately, it has a runtime error. It appears the error
is due to mismatched calling coventions for parameter passing. The
MATLAB interpreter successfully invokes the mexFunction() in my shared
library (.mexw32), but the passed parameters are corrupted.
I've tried GCC's attribute to set the mexFunction() to cdecl,
stdcall, and fastcall, but still no luck.
Anyone know the solution?
Details follow:
MATLAB mexopts.bat

See the underlined portions above. You're not using the Cygwin gcc,
you're really using the MinGW gcc that understands Cygwin paths. So
you're better off asking on the MinGW list.
