5.2. Preparation of the programming environment.

In this subsection I'll shortly present how to prepare programming environment for PXMC under

Linux operating system. Firstly, we need to download three packages:

binutils-2.16

gcc-3.4.3

newlib-1.14.0

purposes. The question which can arise at this moment is, why above packages are so old? For

example current (31.03.07) stable version of gcc is 4.1.2. The answer is very easy. It is possible to

compile all these packages without any problems. Personally I tried to do it also with binutils-

2.17, gcc-4.0.3 and/or gcc-4.1.1. Unfortunately I (and not only I) got errors, which concerned

capability. Namely the support for h8300-coff was removed in newer versions of GNU tool

chain. It is worth to note that h8300-elf is still supported and with small modification of below

steps it should be possible to create it.

When we already have all three above mentioned packages, we need to compile them. The

procedure in most steps is standard one. It means we use ./configure, make and make install.

Only one essential thing is that we need to set up proper switches when we call ./configure.

Because of that the right command ./configure for binutils looks like:

./configure --with-gnu-ld --target=h8300-coff\

--enable-shared

--enable-commonbfdlib \

--with-mmap \

--enable-64-bit-bfd

To proper configure gcc, first we need to unpack gcc and newlib, and after that we need to

create symbolic link from gcc to newlib:

ln -s newlib-1.14.0/newlib gcc-3.4.3/newlib

Then we write:

./configure --target=h8300-coff --with-gnu-ld \

--with-gnu-as \

--without-nls --with-newlib \

--enable-languages=c,c++ \

--enable-target-optspace \

--enable-version-specific-runtime-libs
