Can anyone please give me some clues as to how to build X with thread sup=
port
enabled. I think the right way to do it is to add the relevant options t=
o
config/cf/FreeBSD.cf, something like
#define HasPosixThreads YES
#define ThreadedX YES
#define ThreadsLibraries -pthread /* (or should it be -lc_r ? */
#define SystemMTDefines -D_REENTRANT /* required ??? */
#define HasThreadSafeAPI NO
^^
---------------------------------
Here's the thing - FreeBSD doesn't seem to have thread-safe interfaces fo=
r
functions like getpwnam, getpwuid, getpwent (Solaris has getpwnam_r,
getpwuid_r, getpwent_r), hence lots of unresolved references. Then there=
's
the file
xc/include/Xos_r.h
which contains definitions of same (basically, pwd.h wrappers) for variou=
s =
platforms, but not FreeBSD (I guess at the time FreeBSD didn't have threa=
ds). =
Unfortunately, the wrappers for other platforms are no good, as FreeBSD's=
pwd
structures are different from everything else.
If anyone has gotten the darn thing to compile, could you please send me =
the
relevant patches? Alternatively, is anyone looking into implementing the=
_r
API for getpwent?
Any help will be much appreciated.
Francis
