May be libxml configure script don't detect(force) automatically
windows threads for mingw builds.
In this case user could run it with --with-threads=win32.
I have pthreads-win32 and configure libxml using
./configure --without-ftp --without-http --without-python --without-zlib
no specific options - probably it tests for pthreads before looking into
win32 threads ?
The issue 599241 is not correct as with --with-threads=win32 libxml2
builds fine with and without w32-pthread package installed. So I would
like to propose bug 599241 to be marked either as invalid or as
feature request.
In first case a new issue could be opened - 'automatic detection of
windows thread for mingw* host'.
About feature request - why not libxml to support both threading
models, windows and posix , for mingw* hosts.
See eg
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=%2Fapis%2Fconcep17.htm
- a portable application cannot assume pthread_t is castable from/to an
integer.
(the first reference I found, but i'm sure it's in the posix specs too -
the issue comes up once in a while on comp.programming.threads)
This is the pthread-win32 definition of pthread_t:
typedef struct {
void * p; /* Pointer to actual object */
unsigned int x; /* Extra information - reuse count etc */
} ptw32_handle_t;
typedef ptw32_handle_t pthread_t;
and it's the reason why
tid[i] = (pthread_t) -1;
fails
Setting tid[i] to pthread_self may not be in the right spirit for the
tests I guess, but I don't really know of another way to initialize a
threadid.
