RE: [ECOS] FW: POSIX problems during ARM simulations

["Chip Boling" <cboling at hiwaay dot net>]

I added POSIX through the POSIX package to the 'default' target.  I also
created an eCos image by using the POSIX template during original creation.

At this point I believe it to be a toolchain problem (maybe SID but I doubt
that).  I built various PowerPC simulator versions using pretty much the
same steps and all tests work fine under the GDB/Insight simulator.

I am presently building GCC 3.2.2 and 3.2.3 to test this out.  I tried to
build the GCC 3.3 and 3.3.1 but ran into CYGWIN/GCC compiler problems.  If I
have trouble building 3.2.2 and 3.2.3 I may have to switch over to a Linux
machine and try the samples there.

How did you "add POSIX"?  Have you tried building using the POSIX (or
'net') templates directly?

Note: I just tried this on a different platform and it worked fine when
I built using either the default or net templates.  I had linking
problems when I tried to use the posix template (which I plan to
investigate later).
