I'm trying to cross-compile boost for the Embedded Planet PowerPC 82xx
target platform and have a few questions. This is the first time I've
used jam so I'm a bit disoriented. Can somebody help?
The build platform is a vanilla Redhat 9 system for which the target
processor vendor provides a cross-compiler (ppc_82xx_gcc). This is a
modified version of gcc that builds applications to run under their
Linux kernel/application environment, supplied as a collection of rpm
images. These are installed on the host file system and exported to the
target platform via NFS. All this is in place now and apparently is
working, at least insofar as having compiled ACE/TAO successfully (as
yet untested).
Question is, how do I compile boost for this platform? I've copied
tools/build/v1/gcc-tools.jam to tools/build/v1/ppc_82xx-tools.jam and
changed the GCC/GXX settings in that file to ppc_82xx-gcc and
ppc_82xx-g++ respectively, which is all that should be needed insofar as
their compiler is concerned.
Here's what I'm getting: jam needs to be told the target architecture
somehow. Question is, how do I do this?
