Package: libc6-dev
Version: 2.3.6.ds1-9
Severity: wishlist
Hi,
There is an issue with the /usr/include/semaphore.h file and what
the manpages are saying for sem_open(3) and POSIX specifications
for the semaphore.h file.
In a nutshell, with the libc6-dev package, one can't do
the (basic) following :
#include <semaphore.h>
Without having included pthread.h before. That breaks a few
.c files that would have compiled without any error on other POSIX
systems with the following message :
In file included from test.c:10:
/usr/include/semaphore.h:34: error: field '__sem_lock' has incomplete
type
(where line 10 of test.c is "#include <semaphore.h>").
Maybe should we inlcude pthread.h in /usr/include/semaphore.h ?
Another solution would be to fix the manpages (ie: sem_open(3))
who are just requiring semaphore.h by adding an #include <pthread.>
line.
For the record, users who find this bug while trying
to compile POSIX-semaphore enabled source code can fix
it by adding "#include <pthread.h>" before "#include <semaphore.h>"
Thanks,
Florian Le Goff <[EMAIL PROTECTED]>
