Hi Brett
I'm getting desperate and can not see why I can not cross build after
following all instructions, as far as I am aware, (more or less) exactly.
Before I throw in the towel, could you (or anyone who has managed to cross
compile under cygwin) possibly check out the following details. I have just
spend three days sat in front of the computer studying FAQs, documents with
tips, make file manuals etc. etc. but just seem to be going around in
circles.
So here's what I have just done, to try to avoid the fact that there was
something basically wrong with my configuration (basic instructions
document "fromcygwin-to-linux-cross-howto.txt" ):
1. Reformated hard disk and re-installed Windows (to be sure nothing left
over from some bad configuration)
2. Downloaded cygwin (again) with the following options (gcc make,
binutils, gcc, perl) Is this list complete for what is absolutely necessary
? (I was advised to install EVERYTHING, even the games - advice which I
have not completely followed - should I ? What is your cygwin installation
like ?)
3. Installed cygwin on computer
4. Copied binutils-2.12.tar.gz and gcc-3.0.4.tar.gz to computer in to
cygwin/tmp (I didn't download them again since the error can hardly be here
- I copied them from another PC)
5. Set up the following environment variables:
cygwin$ host=i586-pc-cygwin (The computer is not
the newest and the native build always gave me this host information)
cygwin$ build=i586-pc-cygwin
cygwin$ target=mcore-elf (Target is MCORE)
cygwin$ prefix=/usr/local/mcore
cygwin$ src_root=/usr/local/src/gnu
6. Extracted binutils and gcc new sources as follows
cygwin$ cd $src_root
cygwin$ tar zxf /tmp/gcc-2.95.2.tar.gz
cygwin$ tar zxf /tmp/binutils-2.10.1.tar.gz
7. Build and install binutils for the mcore
cygwin$ mkdir -p $src_root/BUILD/binutils
cygwin$ cd $src_root/BUILD/binutils
cygwin$ $src_root/binutils-2.10.1/configure \
--with-included-gettext \
--target=$target --host=$host --build=$build \
--prefix=$prefix -v
cygwin$ make > make.log 2>&1
cygwin$ make install > install.log 2>&1
This works fine
8. I set the path to the new binutils tools for Mcore
cygwin$ export PATH=$PATH:$prefix/bin
This I check with cygwin$ $target-ld --version, which returns GNU ld
version 2.12...(etc)
9. Build GCC for mcore with
cygwin$ mkdir -p $src_root/BUILD/gcc
cygwin$ cd $src_root/BUILD/gcc
cygwin$ $src_root/gcc-2.95.2/configure \
--enable-languages=c,c++ \
--with-included-gettext --enable-shared --enable-threads \
--target=$target --host=$host --build=$build \
--prefix=$prefix -v
cygwin$ make > make.log 2>&1
This is where there are still problems. libiberty is built fine and then
some other things, but then there is an abort.
Below is the content of make.log when I repeat make, where the first parts
are not repeated as they are already in place.
Once I have the energy again I may have a last attempt at analysing the
configs and makes to see whether I can understand exactly what is
happening, but up to now I have not been able to understand enough of the
syntax for this to be of great use (I think that I must take a few more
days studying the documentation first).
Maybe you (or some one else) can see what is going wrong. I have added a
couple of comments at the right of the output where there may be something
fundamental:
Thanks if you find the time to help out, I would be grateful for any tips -
I'm gradually loosing hope....
Cheers
Mark
