I am trying to create a cross-compiler hosted on linux, which
can compile programs for DOS.
I'm running into trouble I cannot find on dejanews, other web-sites
or even in the FAQ.
I've downloaded gcc-2.8.1.tar.gz, binutils-2.9.1.tar.gz and
newlib-1.8.1.tar.gz. I've also downloaded the cross-gcc faq
0.8.2, one-tree-1.5.sh and crossgcc-gcc-2.8.1.patch.
This was I think all that would be required to make this work, right?
I'm compiling on a heavily patched RH 5.0 system, kernel 2.1.131ac10,
egcs-1.1.1, binutils-2.9.1.
After running one-tree-1.5.sh and configure as per the FAQ:
../src/configure --target=i386=go32 --prefix=/usr/local/cross -v
make all install
I get a linker-script error in ld. I'm not proficient enough in the build
process to have any inkling of what might be going wrong here. I can see
this is when testing gcc to link the new library, and it says 'ignore
linker errors' but somehow I think this is a bit more serious....
I really would appreciate any pointers on what is going wrong here or
what I'm doing wrong here. Also some info on what to use for --prefix above
would be nice. I've tried different settings, and all give the same error,
but I don't really know what I should say there.
Finally, pointers to precompiled binaries of this linux-host, dos-target
compiler-tool would be nice, since I haven't been able to find them.
Below are the last few lines of the on-screen progess of 'make all install':
