Re: build binutils - BFD target names


Hi Muhammad,

I'm working on a project that requires the use of some
not-supported-by-default-on-cygwin target formats (e.g. aout). So I
tried building binutils-2.15.97 with only the formats I need. Tried to
configure it with:
configure --enable-targets=aout --enable-shared --with-gnu-ld --with-gnu-as

Also tried: --enable-targets=aout32 --enable-targets=elf32 --enable-targets=i386-aout32 --enable-targets=i386-elf32 --enable-targets=pe-i386 --enable-targets=i386-pe

Each and every build fails at [configure-bfd] complaining about the target
name being invalid - except with i386-aout32, where somewhere during the ld
build it says i386-pc-aout32 is invalid =/

I tried looking in bfd/config.bfd for the target names (as the error
advised), but I couldn't extract anything meaningful from there.

So,
- What are the target names, or where do I find a listing?

What you want is an i386 targeted linker which can generated output in the AOUT binary file format. So if you look through the config.bfd file for occurrences of "i386aout_vec" you will find those target names which will work. For example I saw " i[3-7]86-*-msdos*" and so I built a toolchain with:


configure --enable-targets=i386-msdos

and viola I had a linker which would produce the required binaries.

Cheers
  Nick
