Odd -- I caught this error just last night and fixed. I'll checkin
later today or tomorrow. I think it's a more strict warning for
gcc4.0 -- the code has technically worked for years :)

I started out with this error:
conn.c: In function ‘NsTclConnObjCmd’:
conn.c:843: error: invalid lvalue in assignment
Line 843 looks like this:
connPtr = (Conn *) conn = itPtr->conn;
The gcc version here is
# gcc --version
gcc (GCC) 4.0.0 20050519 (Red Hat 4.0.0-8)
The exact same tarball was compiled a few weeks ago on an RHEL 4
system
with no problems. The gcc version there is:
# gcc --version
gcc (GCC) 3.4.3 20050227 (Red Hat 3.4.3-22.1)
As a test, I just went back to the RHEL system and touched conn.c. I
got a warning instead of an error.
conn.c: In function `NsTclConnObjCmd':
conn.c:843: warning: use of cast expressions as lvalues is deprecated
I checked the version in CVS and this line has not been changed.
My C skills are a tad rusty but I went in and changed it to this, and
it compiled under FC4:
// connPtr = (Conn *) conn = itPtr->conn;
conn = itPtr->conn;
connPtr = (Conn *) conn;
Is this valid?
I thought I had saved the day, but I ended up stuck on this:
libnsd.so: undefined reference to `pthread_kill_other_threads_np'
That's in nsd/unix.c, in FatalSignalHandler:
#ifdef __linux
/*
* LinuxThreads thread manager needs to kill all child threads
* on fatal signals, else they get left behind as dead threads.
* As of glibc 2.3 with NPTL, this should be a no-op.
*/
pthread_kill_other_threads_np();
#endif
This system has glibc 2.3.5,, but I don't know if I have NPTL or not.
The system on which this builds just fine has glibc 2.3.4.
Suggestions?
thanks,
janine
