Setting up an MSYS environment and cross-compiler
This chapter provides instructions on how to set up an MSYS environment with a cross-compiler that is appropriate for the PCIe hardware, and configuring the environment to correctly build the FM binaries.
The process includes these general steps:
1.Download the required binaries and source code (See Download MinGW and the toolchain source code).
2.Build the cross-compiler (See Build and install the cross-compiler).
3.Add the ProtectServer paths to the MSYS environment (See Set the MSYS environment to include the FMDIR and CPROVDIR directories).
Download MinGW and the toolchain source code
Download the following files:
| Filename | Source file | Location |
|---|---|---|
| binutils-2.26.tar.gz | binutils 2.26 | http://ftp.gnu.org/gnu/binutils/ |
| gcc-5.3.0.tar.gz | gcc 5.3.0 | http://ftp.gnu.org/gnu/gcc/gcc-5.3.0/ |
| newlib-2.4.0.tar.gz | newlib 2.4.0 |
https://sourceware.org/newlib/ Follow the "Download" link and find the source snapshots in the newlib ftp directory. |
Extract the binutils, gcc and newlib source files into the same folder. This will be referred to as the %SRC% folder. Ensure that the %SRC% path has no spaces.
Go to: http://www.mingw.org/ or https://sourceforge.net/projects/mingw/ to download MinGW.
Install MinGW in the default directory (C:\MinGW) or a directory of your choice. This directory will be referred to as %MINGW_HOME%.
NOTE If you install MinGW in another directory, ensure that the path does not contain spaces. For the automated scripts to work, the %MINGW_HOME% environment variable must also be set to the install directory.
Build and install the cross-compiler
There are two options for this process:
>run the provided script that builds and installs the cross-compiler and sets the MinGW environment, or
>complete the steps manually by following the instructions below.
Automated cross-compiler build
1.Copy the files crossc.cmd and crossgcc.mak from C:\Program Files\SafeNet\Protect Toolkit 5\FM SDK\gcc_fm\ into the %SRC% folder.
2.Run crossc.cmd from a command prompt.
NOTE If you installed MinGW in another directory other than the default (C:\MinGW), set the %MINGW_HOME% environment variable to that path before running the script.
Manual cross-compiler build
1.Using either the MinGW GUI or the CLI, install the following packages:
•mingw32-base
•mingw32-gcc-g++
•mingw-developer-toolkit
•mpc-dev
•mpfr-dev
•gmp-dev
Using the CLI:
%MINGW_HOME%\bin\mingw-get install mingw32-base mingw32-gcc-g++ mingw-developer-toolkit mpc-dev mpfr-dev gmp-dev
2.Go to the %MINGW_HOME%\msys\1.0\bin directory and run bash -c 'mount --replace "%MINGW_HOME%" /mingw'.
cd %MINGW_HOME%\msys\1.0\bin
bash -c 'mount --replace "%MINGW_HOME%" /mingw'
3.Open an MSYS shell. You might want to create a shortcut on the desktop for easy access. This shell will be used later on to compile the FM binaries.
%MINGW_HOME%\msys\1.0\msys.bat
4.Go to the %SRC% folder.
cd $SRC
5.Set up the build environment.
export TARGET=powerpc-eabi
export PREFIX=/mingw
6.Build the binaries by executing the following msys commands, in this order:
a.Build binutils:
tar xvf binutils-2.26.tar.gz
mkdir binutils_build
cd binutils_build
../binutils-2.26/configure --prefix=$PREFIX --target=$TARGET --disable-nls --disable-shared --with-gcc --with-gnu-as --with-gnu-ld --with-stabs --disable-multilib --enable-thmake all-gccreads
make all
make install
cd ..
b.Build gcc - C only:
tar xvf gcc-5.3.0.tar.gz
mkdir gcc_build
cd gcc_build
../gcc-5.3.0/configure --target=$TARGET --prefix=$PREFIX --with-cpu=440fp --enable-languages=c,c++ --disable-multilib --with-gcc --with-gnu-ld --with-gnu-as --with-stabs --disable-shared --enable-threads --disable-nls --with-newlib
make all-gcc
make install-gcc
cd ..
c.Build newlib:
tar xvf newlib-2.4.0.tar.gz
mkdir newlib_build
cd newlib_build
../newlib-2.4.0/configure --target=$TARGET --prefix=$PREFIX
make
make install
cd ..
d.Build gcc - complete:
cd gcc_build
make all
make install
cd ..
Set the MSYS environment to include the FMDIR and CPROVDIR directories
NOTE If you installed MinGW in another directory other than the default (C:\MinGW), set the %MINGW_HOME% environment variable to the install directory you selected.
In the %FMDIR%\bin directory, run the setmsysenv.cmd script. This will add the environment variables CPROVDIR and FMDIR to the MSYS environment, allowing you to compile the FM binaries. This only needs to be done once.
