Currently on Linux, you must run rpcbind in insecure mode (-i) in
order for ttsession to register with rpcbind (the portmapper). This
is because, on most systems, libc contains an older sun-based rpc
library embedded within it. The sun-rpc code does not know how to
authenticate with rpcbind when run as a non-privileged user.
Using libtirpc, ttsession can register with rpcbind without requiring
it to be run in insecure mode. You must have the libtirpc-dev, or
equivalent package installed to use it.
If you want to try this:
- install libtirpc-dev or equivalent
- if your rpcbind process is already running in insecure mode (-i
option), remove that option and restart it.
- edit config/host.def, (create if it doesn't exist) and add:
#define HasTIRPCLib YES
- rebuild CDE (make World). It's probably a good idea to remove
/usr/dt/* beforehand to avoid contamination.
Some linux systems seem to incorporate tirpc directly into libc (as
all of the BSD's do AFAIK) so this may not be needed.
I know that at least on Ubuntu systems defining HasTIRPCLib to YES is
required in order to run rpcbind without -i.
this means the compiler treats them as system headers and does not give you
excessive warnings from them. This is used because X11 does not like the
-ansi and -pedantic warnings that CDE is compiled with.
Added proper SharedDtSvcReqs in lnxLib.tmpl and CplusplusLibC in
linux.cf. This allows the libstdc++ dependancy to be properly
declared for libDtSvc so that it is not neccessary to hardcode 'CCLINK
= g++' in the Imakefiles of programs linking angainst libDtSvc.
- also some rework of linux.cf
- only allow ELF systems
- use -pipe
- add some more defines
- get rid of some of the ancient (libc5/linux 1) support. Really,
don't expect CDE to build right on such old systems.
Remove from individual Imakefiles.
Also, remove '#if 0' block in linux.cf, and remove empty
LinuxMachineDefines. This should be working correctly. If not, let me
know.
