RE: [ECOS] eCos 1Aug release ARM7 posix build error.

[<felixwong at i-technologies dot cc>]

I have recompiled to GCC 2.95.3.  The error message is gone.
The library file & startup files compiles with no error.

I wish the eCos will work soon with GCC3.0.  Which enhanced a lot
in the optimizing ARM7TDMI with THUMB & ARM instruction sets.

However, anyone knows I can use THUMB & ARM mixed code with
eCos libraries (created with GCC 2.95.3)?  GCC2.95.3 seems not suppose 
to have mixed codes? (Please correct if I am wrong).

Any idea?

Thanks a lot.
Felix.

You are building with GCC 3.0, rather than 2.95 as we are still
recommending for arm-elf - partly for reasons like this :-). We are
updating our sources to work with the gcc 3.0, but this still isn't
complete.

You can avoid this problem by recompiling your tools - but this time also
check out newlib (http://sources.redhat.com/newlib ). Then in your gcc
source tree, at the top level (where there are directories like bfd config
include gcc libstdc++-v3 etc.) symlink the newlib and libgloss directories
in, e.g.

ln -s PATHTOCHECKOUTNEWLIB/src/newlib
ln -s PATHTOCHECKOUTNEWLIB/src/libgloss

Now rebuild gcc from scratch and instead of using "make all-gcc
install-gcc" use "make all install".

This should hold off the problem until the transition in the eCos sources
is complete.
