Hi,
While cross-compiling sudo 1.8.3p1 for power pc, it fails at linking error_jmp. Please see the failure dump:

It sounds like your system has dlopen() but libtool doesn't recognize it.  Can you attach the config.log file?

config.log file

Find the config.log file.

Comment 3 Todd C. Miller 2012-03-13 10:50:34 MDT

The problem is that libtool doesn't think that shared libraries are supported (which is incorrect).

configure:13392: checking if libtool supports shared libraries
configure:13394: result: no
configure:13397: checking whether to build shared libraries
configure:13418: result: no
...

This is probably because you didn't specify the host operating system.  You probably want something along the lines of  --host powerpc-montavista-linux

If that doesn't help, you can just build sudo without shared object support by passing configure the --disable-shared option which will just build a static version of sudo without plugin support.

Comment 4 Todd C. Miller 2012-05-17 11:26:30 MDT

Incomplete --host argument was specified.  Sudo 1.8.4 and higher will error out in configure if the system dlopen status conflicts with what libtools know about.
