[Buildroot] Boost package settings for using cross-compiler ?

[Buildroot] Boost package settings for using cross-compiler ?

[MikeW]

I successfully (so I thought) created a package file for building the Boost C++
libraries under buildroot, but when I came to use them, found they had been
built using native (i386) tools, unlike the rest of the libraries built
by Buildroot, which were ARM architecture.

The top-level Boost config parameters do not appear to have a tool
prefix or macro to support cross-tools.

So - has anyone built Boost successfully before ?

I imagine that if so, the distribution would already contain
a package file for the library ...

Regards,
Mike

Hi,

we use boost with ppc crosscompiler, here is my buildroot package.

Sure, its depend an bjam installed on host, the buildroot C++ toolchain, theading, zlib, ....
Realy, a big package for an embedded device ;-)

Check the boost configuration in boost.mk!

claus

Thanks - I worked around this in my own boost.mk by putting
GCC_ROOT_DIRECTORY (why not _DIR ??) =$(STAGING_DIR)/arm-linux-xxx
within my "$(MAKE) ...<here!>.... all" target command line.

This then allows the Buildroot tools to alias the native gcc tools
without any prefixes. Shame that Boost's own makefile doesn't use CC.

Just have to solve to toolchain EABI version problem now :(

Mike
