How to build a toolchain for the PSXSDK
----------------------
If you do not have the patience for this, do not do this. Unless you have
some less used operating system and/or using a non-x86 processor on your development computer there are precompiled toolchains on the main PSXSDK site for some of the most common operating systems.
These instructions are for Unix-like operating systems, although they will
probably work also on Cygwin.
To build a toolchain for the PSXSDK, you need to download GNU Binutils
(http://www.gnu.org/software/binutils/) and GNU GCC (http://gcc.gnu.org)
It is assumed that you want to install the toolchain you are going to build in
/usr/local/psxsdk. If you don't want to do that simply replace it in the
commands with something else.
If you are using a *BSD system, replace `make' with `gmake'.
First of all, open a terminal.
Then the following is a guide for what you will do:
# export BASEDIR=<directory-where-you-downloaded-binutils-and-gcc-source-archives>
# cd $BASEDIR
# mkdir source build
# tar xjf binutils*bz2 -C source
# tar xjf gcc*bz2 -C source
# cd build
# mkdir psxsdk-binutils
# mkdir psxsdk-gcc
# cd psxsdk-binutils
# $BASEDIR/source/binutils*/configure --disable-nls --prefix=/usr/local/psxsdk --target=mipsel-unknown-elf --with-float=soft
# make
# make install
# cd ..
# cd psxsdk-gcc
# $BASEDIR/source/gcc*/configure --disable-nls --disable-libada --disable-libssp --disable-libquadmath --disable-libstdc++-v3 \
--target=mipsel-unknown-elf --prefix=/usr/local/psxsdk --with-float=soft --enable-languages=c,c++
# make
# make install
Replace <directory-where-you-downloaded-binutils-and-gcc-source-archives> with the directory where you
put the binutils and gcc source archives you downloaded.
If you don't need C++ support, replace "--enable-languages=c,c++" with "--enable-languages=c" and remember
to set CXX_SUPPORT in Makefile.cfg to `no'; that will avoid C++ support in PSXSDK from being compiled.
Note that on some systems (like NetBSD) for some reason GCC might not build if you run its configure script using a relative path
(like ..). This happens for a strange reason. In doubt, run the configure script using an absolute path (the complete name of the directory).
Now you just need to build the PSXSDK. Notice that the PSXSDK installs itself
after building automatically and you will not need to execute a command to install it after building it.
Before building the PSXSDK, edit Makefile.cfg. TOOLCHAIN_PREFIX is very important,
it specifies the directory where the PSXSDK toolchain is installed in. In our example it is /usr/local/psxsdk (the default)
There should be explanations for the other variables.
To build the PSXSDK go into its directory, change your path variable to include the PSXSDK toolchain binaries:
export PATH=$PATH:/usr/local/psxsdk/bin
and execute "make".
If everything went well, execute "make install".
PSXSDK should be ready to go!
