RE: [ECOS] how to link sevral *.o file into one *.o?

[Schumacher, Gordon]

Why do you want them in a .o file?  Are you trying to link them (i.e., into
an executable or binary image)?
.o files are "object" files - you can't actually do much with them, other
than link them into an executable.
If you really want to do that, for some reason, instead of calling "gcc foo.
c -o foo.o" and then "gcc bar.c -o bar.o", try "gcc foo.c bar.c -o foo.o".
I'm not at all clear that this will actually work, though.

If you're after an executable, you probably want "gcc foo.o bar.o -o
myapp.out", or some such.
For a library, you want to use libtool - there's a multitude of options
you're going to want to look at.

I'd suggest that you look at the GNU documentation for these tools.
GCC: http://gcc.gnu.org/onlinedocs
libtool:
http://www.gnu.org/manual/libtool-1.4.2/html_chapter/libtool_toc.html

If you have further questions, feel free to e-mail me (but I think that this
is kind of out of the scope of the eCos list.)
