Hello,
[Sending this from a new system; hope it appears in plain text.]
On a new Windows 7 64 bit laptop with
mingw-w64-1.0-bin_i686-mingw_20110318.zip and an old msys
copied from my XP 32 bit laptop, the command
find /c/opt/msys /c/opt/mingw -name "*gcc*exe" | xargs ls -laF
shows 4 matches:
1) [...] 726920 Mar 18 12:56
/c/opt/mingw/bin/x86_64-w64-mingw32-gcc-4.5.3.exe
2) [...] 726920 Mar 18 12:56 /c/opt/mingw/bin/x86_64-w64-mingw32-gcc.exe
3) [...] 726920 Mar 18 12:56 /c/opt/mingw/mingw/bin/gcc.exe
4) [...] 726920 Mar 18 12:56 /c/opt/mingw/x86_64-w64-mingw32/bin/gcc.exe
For "gcc.exe --version", all 4 gcc.exe report:
(GCC) 4.5.3 20110318 (prerelease)
What is the purpose of each of the 4 gcc.exes -- what are they
to be used for? I am aware that the 32 bit mingw offers two
sets of compilers, one for building native windows
applications and the other for building "MSYS" applications
(applications that only run in a terminal that was somehow
tied to MSYS) -- is there something similar for mingw-w64?
My main use will be for building 64 bit gvim and perl modules
(for the 64 bit perl offered by Active State).
Also, what does the "32" in mingw32 signify? Even though
mingw-w64-1.0-bin_i686-mingw_20110318.zip runs on 64 bit
Windows and is for building 64 bit Windows applications, it is
in itself a 32 bit windows application?
Thanks,
--Suresh
