[ECOS] Problem using the POSIX template

[ECOS] Problem using the POSIX template

[Neugebauer Manfred]

Hallo,
 
We started to use eCos 2.0 on Suse Linux 9.2 on a PC. We were successful to create a minimal configuration with the configtool and boot it via a floppy.

We recognized that we need the POSIX template to have access to functions as pthread_create(). However, the problem with this configuration is that we get unresolved link messages for "printf()". I looked at the mail archive and recognized that others had already this problem, but the mail exchange stopped before this issue was resolved. How do I solve this problem?
 
We also tried to use the "all" configuration, but we get linking errors due to doubled defined communication functions.
 
Mit freundlichen Grüßen - With Regards
 
Manfred Neugebauer

First thing, I'd *really* suggest that you use the CVS version of eCos.
Version 2.0 is now more than 2 years old.

When you switched templates, did you start fresh, or try to do it in
the same build directory?  If so, this is a problem as the makefiles
don't always work well when [potentially] massive changes like a new
template are made.
