Not declared errors when compiling Windows vm

Hi!

I'm trying to get Windows VM compiled with Msys, using the Cog source code in the git repository. I've almost surpassed everything, but I'm having some "not declared" errors like this:

c:/MinGW/msys/1.0/home/Guille/cog/gpolito-cogvm/platforms/win32/vm/sqWin32Intel.

c:1250:27: error: '_MCW_EM' no se declar¾ aquÝ (primer uso en esta funci¾n)

related to these lines of the sqWin32Intel.c file:

...

#define FPU_DEFAULT (_RC_NEAR + _PC_53 + _EM_INVALID + _EM_ZERODIVIDE + _EM_OVERFLOW + _EM_UNDERFLOW + _EM_INEXACT + _EM_DENORMAL)

...

in squeakExceptionHandler and sqMain

_control87(FPU_DEFAULT, _MCW_EM | _MCW_RC | _MCW_PC | _MCW_IC);

...

However, if I comment those lines, I can compile and everything seem to work :/.

I googled a little but I've not found anything that helps me... Has anyone has this problem? Is it a Msys configuration problem?

Thanks!

Guille

hmm..
weird.
I cannot check right now, but i can check when will come home and try
building it on my windoze machine.

Are this line were added recently, because i don't remember seeing it
in win32 sources..
Or maybe it was always there, then its a question why it refusing to
compile for you

Hi Guille. I just tried everythign from scratch in a windows box and I could build, I couldn' reproduce your issue. There was a problem that the make won't link correctly, and this was because the targetDir was wrong for Windows. I have just fixed that in CMakeVMMaker-MarianoMartinezPeck.145
but that has nothing to do with your problem.

Cheers

Thanks!

Re: Not declared errors when compiling Windows vm

Ok, I made it work linking C_INCLUDE_PATH to where the right float.h is ¬¬

Guille@arkha ~/cog/gpolito-cogvm/build

$ C_INCLUDE_PATH=/c/MinGW/include/

Guille@arkha ~/cog/gpolito-cogvm/build

$ export C_INCLUDE_PATH

But I don't know why I have not that as a default! :S

Thanks,

Guille

Re: Not declared errors when compiling Windows vm

BTW, important information I missed:

Mingw version 3.20

Cmake version 2.8.7

My Mingw/msys installation (recommended and default in the latest version of mingw) is

MinGW -> C:\MinGW

Msys -> c:\MinGW\msys\1.0

Windows XP

My path env variable:

.:/usr/local/bin:/mingw/bin:/bin:/c/WINDOWS/system32:/c/WINDOWS:/c/WINDOWS/System32/Wbem:/c/Program Files/Git/cmd:/c/Program Files/Git/bin:/c/Program Files/CMake 2.8/bin:/mingw/bin:/mingw/lib:/usr/lib/:/usr/bin/:/usr/local/bin/

Thanks!
