building newlib for mingw32
Fri Mar 14 23:59:00 GMT 2003
I've been reading for days, and still can't quite come up with the answer
to several problems/questions.
We are attempting to bring over some internally developed libraries and
code from what compiles on a variety of *nix boxes to Winblows.
We're using a mingw32 with Msys environment, and are looking to newlib to
provide a lot of the library functionality which MSVCRT doesn't. While we
don't rely on a lot of library calls, mingw32 seems to not have values in
the include files for a lot of common library routines. So, although you
might link with liberty,
a lot of the defines are missing...and I understand from a licensing
We realize we will have to fill in a lot of what windows doesn't natively
provide [ i.e. system calls ] but we were hoping to use newlib to
accomplish some of what we couldn't accomplish easily with liberty & mingw.
Problem 1: configure. I've followed the README, but the configure script in
the top level build directory does not recurse.
And, if I use ../../newlib/configure, then the include path is wrong, and
the .c's can't find libc/include.
Problem 2: I worked around problem 1 manually. I then created stubs for all
the system calls that newlib makes [ and it makes a few ], I will fill them
But, I get linker errors complaining that gcleanup and wsbrk are multiply
defined...i.e. in freer.o and mallocr.o.
So, I'm sure some of you have been down this porting road before. If this
is the right direction to go to accomplish this, perhaps you can help me
with the two problems above. If not, perhaps you can put me on the right path?
