Re: [ECOS] problems compiling host tools

[Aldo Dolfi <dolfi at nec-labs dot com>]

Thank you for the answer.

I made some tries, but I did not get what exactly you meant by starting 
from 1.3.1 and upgrading to CVS.
If I run cvs checkout in the 1.3.1 tree I get errors that say a lot of 
files are in the way. Updating is not possible either because that tree 
has not CVS directories.

Anyway, I found out that the normal cvs co described in the site does 
not check out the host directory. I had to check it out separately. I 
was able to compile the host tools. Then, in a separate directory 
(jessica) and I ran
ecosconfig new pc
ecosconfig tree
make
and this went on without pb.
In a new directory (jessica2) I tried to build the hello.c example. I did
SRCS=hello.c DST=hello ../ecos-cvs/examples/build_Makefile ../jessica
and then
make

and I got the linking errors in the attached file.

What's the problem here? It looks like the library does not define some 
symbols.
Do you have any idea?

Thank yoy again
Aldo
