GNUmex编译器工具，在Matlab做C/C++开发的。。

CHANGES TO GNUMEX BETWEEN VERSIONS 1.11 AND 1.12. 1. The mex-files uigetpath and shortpath have been recompiled and the new versions are compatible with, and called if, the Matlab version is >= 7.4. Comments at the start of uigetpath.c and shortpath.c have been modified (but otherwise these files are unchanged). 2. Gnumex now creates .def-files if needed. Starting with Matlab 7.4 there are no libmex.def, libmx.def and libmat.def that come with Matlab. In earlier Matlab versions these reside in <matlabroot>\extern\include. The .def files are written in the directory where gnumex.m is located. 3. The gcc option -mcpu=pentium has been deprecated (from gcc version 3.4.0 according to "Google"), and instead one Gnumex uses -march=pentium which is also comptible with older gcc versions 4. The -mrtd flag has been removed for Fortran compilation (KJ had a nasty crash with a Fortran program using large arrays and could not resolve it the -mrtd flag was dropped). 5. The mex file extension was changed from .dll to .mexw32 in Matlab version 7.1 and the new Gnumex honours this. 6. A bug was fixed on line 733 of version 1.11 gnumex.m. When directories were nonexistent fp was used without being defined. 7. The switch -funroll-all-loops has been added to Fortran compilation. 8. A potential "year-2000" problem with mlv was fixed. The old definition would fail if and when Matlab reaches version 10. 9. The switch -fleading-underscore was removed from Fortran compilation (it is the default anyway, and just causes confusion with the switch -fno-underscoring, which is necessary) 10. Gnumex now locates both the Cygwin and Mingw folders (or does its best to locate them), instead of setting the Mingw folder always to c:\Mingw. 11. Gnumex now defaults to using Mingw instead of Cygwin, unless it finds Cygwin and not Mingw, for reasons explained in the README.TXT file. 12. A g77-compatible example mex Fortran program accompanies Gnumex 1.12. An engine demo Fortran program is also included now. 13. A new README file has been written. 14. Changes were made to "gnumex test" to (possibly all due to changes in Matlab Mingw and Cygwin since it was written). On my machine it now runs with everything OK (cygwin engine does not work and is not tested). Except for no. 1, 2, 13 and 14 these changes all only affect gnumex.m. Kristjan Jonasson (jonasson@hi.is) CHANGES BETWEEN VERSION 1.12 AND 1.13 The changes are mostly cosmetic. Comments at the start of gnumex.m were updated slightly (and version number corrected). An extraneous file (mexopts.bat) was removed and rccompile.pl (which may be needed by some older Windows/Matlab versions) was added again (it was somehow lost between v1.11 and v1.12).
