With RedHat 5.0 distributions of Linux, it's best to upgrade the distribution with these:
There is a bug in getsockname ()
on versions of Linux
through 2.0.34. getsockname ()
returns an Internet host
address of 127.0.0.1 (localhost) instead of 0.0.0.0 for sockets that
aren't connected. This bug prevents TAO servers from working
correctly. To fix it, comment out these two lines in function
inet_getname ()
in
/usr/src/linux/net/ipv4/af_inet.c
:
} else { __u32 addr = sk->rcv_saddr; if (!addr) { addr = sk->saddr; /* comment out this line: if (!addr) */ /* comment out this line: addr = ip_my_addr(); */ } sin->sin_port = sk->dummy_th.source; sin->sin_addr.s_addr = addr; }and rebuild your kernel. This fix has been implemented in 2.1.x versions of the kernel.
Without the following patch from Scott Snyder <[email protected]>, egcs 1.0.1 on Linux won't be able to compile netsvcs/lib/Server_Logging_Handler.cpp:

The first patch is for the GNU assembler, gas. It is only necessary on Alphas, and only when
-g
is used. If you don't want
to patch the assembler, you can enable the SUPPRESS_DASH_G option in
the platform_linux.GNu
. Otherwise, this patch can be
applied to the binutils gas source. Then, rebuild and install as.
The file to be patched is binutils-2.8.1/gas/config/tc-alpha.h:NOTE: this patch isn't necessary with binutils-2.9.1.

In addition, you'll need to patch
/usr/src/linux/include/linux/posix_types.h
as follows
to avoid compilation errors:

Finally, on Alpha only, I removed wrapsyscall from the LinuxThreads library by patching linuxthreads/Makefile:
36c36 < semaphore wrapsyscall --- > semaphore # wrapsyscallWith that and the above configuration/pathes, all ACE tests run perfectly cleanly on Alpha!
