[edit] Cross Compilation for SAFplus

[edit] Create toolchain

  • Download or build your own toolchain for a target platform:
A toolchain can be downloaded at http://www.mentor.com/embedded-software/codesourcery.
Tools to generate cross-compilation toolchain:
http://crosstool-ng.org/
http://buildroot.uclibc.org/
  • Configure the toolchain:
In your toolchain location, check if the config.mk file exists. This file is included in the cross build makefile. If your toolchain tarball does not include this file, please create it manually. Basically, the file contains the following configuration variables: 
   ARCH=i386
   MACH=i686
   TARGET=i686-unknown-linux-gnu
   TOOLCHAIN_VERSION=0.1
   export ARCH MACH TARGET TOOLCHAIN_VERSION

[edit] Building the prerequisite SAPlus 3rdparty libraries for a target platform

  • Export your configuration toolchain 
  $source <location of toolchain>/config.mk
  • Goto <SAFplus SDK dir>/src/SAFplus/3rdparty/base: 
  $make PREFIX=<path to locate thirdparty libraries>
Prefer using the location of toolchain.

[edit] Building SAFplus libraries with a specific toolchain

  • Configure SAFplus libraries 
  $<SAFplus SDK dir>/src/SAFplus/configure --with-sdk-dir=<SAFplus SDK dir> --with-safplus-build --with-cross-build=<your toolchain name>
  • Goto asp/build/<toolchain name> 
  $make asp-libs

[edit] Building a user model with a specific toolchain

  • Goto model project folder 
  $<SAFplus SDK dir>/src/SAFplus/configure --with-sdk-dir=<SAFplus SDK dir> --with-cross-build=<your toolchain name> --with-model-name=<model>
  • Goto asp/build/<toolchain name> 
  $make
