Hi,
I try to compile the pthreads-win32 library for winCE, but I can only
get a dll and a lib on the x86 format (using VC++6 to compile).
When I make a project in embedded Visual C (3 or 4), I get an error
"can't found process.h".
Is there a way to compile it in the ARM, MIPS or other format ?
Thank you for your help

Did you define WINCE in the project?
I compile pthreads for ARM using Micrsoft's Embedded Visual C++ 3.0
regularly and haven't had any problems. I have the following defines in
the config.h file:
#ifdef WINCE
#define NEED_DUPLICATEHANDLE
#define NEED_CREATETHREAD
#define NEED_ERRNO
#define NEED_CALLOC
#define NEED_FTIME
#define NEED_SEM
#define NEED_UNICODE_CONSTS
#endif
And the following in every file that includes <process.h>:
#if !defined(_UWIN) && !defined(WINCE)
#include <process.h>
#endif
Best Regards,
James Ewing

I have now declare WINCE, HAVE_CONFIG_H, and add some macros for
<process.h> and <sys/timeb.h> too.
The project now compile, with a warning :
ptw32_getprocessors.c(67) : warning C4013: 'GetProcessAffinityMask'
undefined; assuming extern returning int
But when it links I get these errors :
pthread.obj : error LNK2001: unresolved external symbol _errno
pthread.obj : error LNK2019: unresolved external symbol
_GetProcessAffinityMask referenced in function _ptw32_getprocessors
The _errno function is in the project and compile, I don't understand
why the linker don't find it.
The _GetProcessAffinityMask looks like a standard function for thread,
but I don't find it in the eVC include.

Hi Benoit,
I've attached my modifications to the ptw32_getprocessors.c file that
fixes the GetProcessAffinityMask for WINCE. It just forces the processor
count to one.
I looked in the pthread.h file and found that if you don't have _UWIN
defined, pthreads own internal _errno will be used. Make sure _UWIN is
*not* defined. See line 1143 in pthread.h.
It was many moons ago that I tweaked pthreads for WIN32 for WINCE and
I've forgotten much of what needed to be done. If anyone wants a diff of
my build against the current CVS version just let me know and I'll send
it out. It might be a good idea to test it a bit and then merge it into
the main CVS tree. I use the same source for both WIN32 and WINCE
pthreads builds.
Best,
James

Hi James,
Thanks a lot for your help.
I'm now able to compile the project for the emulator PocketPC2003 under
eVC4.
But when I try to compile for ARMv4, I get this error :
"pthread_cancel.c(59) : fatal error C1189: #error : Module contains
CPU-specific code; modify and recompile."
Looking at the code just before, I want to add something like that :
#if defined(_ARM_)
#define PTW32_PROGCTR(Context) ((Context)."something here")
#endif
but Iar, Fir or Eip don't work.
And I really don't know what I can put there.
Thank you again.
Benoit

Hi Benoit,
Try inserting the following:
#if defined(_ARM_)
#define PTW32_PROGCTR(Context) ((Context).Psr)
#endif
