readme.binutils

A C++ class library for scientific computing

If you are using blitz with egcs under Solaris, SunOS, or OSF/1
you may need to use the gnu linker.

You can download the binutils from ftp://prep.ai.mit.edu/gnu/binutils/

From Peter Nordlund:

My experience with blitz and sun is that you need the gnu linker.
At least I had the same problem, and by using gnu-binutils-2.9.1 I got
it to work.

It can be somewhat tricky to get egcs to use the gnu-linker also.
So how I do it migth not be the only way, but it worked for me.

1. Install binutils-2.9.1 
2. Create the bin directory where the egcs compiler will be installed.
3. create links from the linker and assembler to the egcs-bin-dir.
4. configure and install egcs.

See the commands I used below.
---------------------------
mkdir BUILD; cd BUILD
mkdir ../egcs-1.1a/bin
pushd ../egcs-1.1a/bin
ln -s /misc/cvap/gnu/binutils-2.9.1/bin/ld .
ln -s /misc/cvap/gnu/binutils-2.9.1/bin/as .
popd
../src/egcs-1.1a/configure --prefix=/misc/cvap/egcs/egcs-1.1a
--with-gnu-as --with-gnu-ld
make bootstrap-lean ; make install
