Re: Does static library works ?
In the distributed sources there is just one test case (self1.c) that
runs for the static case, and it checks that the library is able to
perform an implicit creation of a POSIX thread handle, i.e. as the
library will do whenever a POSIX thread routine that requires a POSIX
handle is called from a Windows native thread. Pthread_self() is the
only routine in the library where this is done and all other pthreads
routines call it if required.
There is one other check that should be done for static linking (but
isn't), which is to check that the destructors, for TSD etc, actually
run as required. Otherwise, as observed, all other functionality of the
library is tested using the DLL version.
I felt that repeating all the tests for the static case is a redundant
exercise when the additional static functions rarely if ever change. If
Richard has successfully run all the tests with his modified makefile
without modifying the tests sources then the implicit resource create
and destroy logic in the static library hasn't really been tested
because only one or two tests actually result in implicit resource creation.

However, some didn't want to use the DLL... therefore the implicit
creation/destruction of resources (as well as the implicit invocation
of TSD optional destructors) must be carried out explicitly by the
user in the event that they want to use a static library. These
methods are _np (non portable).
I would have expected that the test cases would have been
conditionally compiled to accommodate the testing of the static
version of the library...

Quoting Arnaud RICHARD <firstname.lastname@example.org>:
I have tried with MinGW.
It doesn't pass either. (but pass in dynamic of course).
So it is not due to something specific to MSVC.
Looking more closely... I found out than some functions must be called
only when linking statically:
There is some explanations in the file README.NONPORTABLE
It's the first time ever I see code specific to static linking...
maybe because I'm a newbie on MS platform.
I post this solution for future

I tried to build my program statically with pthreads.lib.
It crash at run-time in "pthread_cond_init()".
So I tried to run the tests.
First surprise: the test suite only run with DLL, and not with .LIB.
I have enhanced the makefile to run the tests in static.
Second surprise: most tests fails (but not all).
Has anyone tried to do it ?
I attached the modified makefile, the target to run is "make clean
Any feedback welcome,
PS: I use MSVC2008, and compile "VC-static"
