Building a cross-compiler for i586-pc-msdosdjgpp under gcc-2.95.1fails

Building a cross-compiler for i586-pc-msdosdjgpp under gcc-2.95.1fails

[Alex Buell]

I've been trying to build a cross-compiler so I can port some of my UNIX
code to 32bit DOS with gcc-2.95.1 - but it blows up with an error at the
following point:

I have successfully built and installed binutils-2.9.5.0.16 targeted for

Any ideas or patches?

It is known problem.  fast fixincludes seems to be incompatible with DJGPP
header files. For native build (DJGPP) fast fixincludes does not work at
all (no working fork()). For building cross-compiler under Linux it breaks
header files.

Download source archive for DJGPP (gcc2951s.zip)
and use script I included for cross-compiling (I have tested that it works
on i586-pc-linux-gnu). I used hack to avoid running fast fixincludes
for cross-compiling.

Will this be fixed for 2.95.2, one would hope?

OK, I shall try that. However, living in Britain has its disadvantages,
expensive on-line phone charges. Do they provide this as a patch for pukka
2.95.1 that I can download and patch my vanilla copy of 2.95.1?

It's does not byte for native build for targets i[3456]86-pc-msdosdjgpp
as fast fixincludes crashes immediatelly. I didn't want to mess with fast 
fix-includes for cross-compiling only so I used some hack to
prevent it to run. Also I thought that it's better to use the same sources also
for building cross-compiler.

download  gcc2951s2.zip from DJGPP distribution (about 45K). It contains
script I'm using to generate source archive for DJGPP (and needed patches
of course). You'll still need original gcc-2.95.1 and libg++-2.8.1.3 sources.

Building a cross-compiler for i586-pc-msdosdjgpp under gcc-2.95.1fails

Oops. I forgot to add, I used the following to configure the compiler:

 ../gcc-2.95.1/configure --prefix=/usr --target=i586-pc-msdosdjgpp
