Re: [Boost-users] Boost configure options for crosscompilation ?
This is the command line I used to build boost using Bjam for an arm platform, not sure if that helps with what you need, but here it is anyway!! bjam "-sGCC_ROOT_DIRECTORY=/opt/montavista/mobilinux/devkit/arm/iwmmxt_le" "-sGCC=iwmmxt_le-gcc" "-sGXX=iwmmxt_le-g++" stage Stage is the folder in which all the libs are placed, other parameters should be self explanatory.

I would like to crosscompile Boost under Buildroot.
I created what appeared to be a successful package file, but found that the native compiler and tools were used rather that Buildroot's crosscompiler toolchain.
However, I could not see any other 'configure' options to switch to using a crosscompiler (EPREFIX looked promising at first but seems to be a path prefix, rather than a tool prefix such as "arm-linux-").
I note an earlier post (unable to post a 'follow-up' to it) seemed to successfully do a cross build.
Could you tell me how Boost is 'configure'd to use the crosstools rather than the native tools ?
Thanks, Mike

This is the command line I used to build boost using Bjam for an arm platform, not sure if that helps with what you need, but here it is anyway!!
bjam "-sGCC_ROOT_DIRECTORY=/opt/montavista/mobilinux/devkit/arm/iwmmxt_le" "-sGCC=iwmmxt_le-gcc" "-sGXX=iwmmxt_le-g++" stage
Stage is the folder in which all the libs are placed, other parameters should be self explanatory.

Thanks, but boost_1_33_1 is distributed with a 'configure' file, and it should be possible to set options on this to get a cross-build. Just need to set a "arm-linux" prefix on each of the toolnames ... somehow. Even so, will have a look at your command to see if/how it can be used. Thanks. Mike

What makes you think it "should be possible"? The configure script is just a thin shell around the bjam commands. And by thin I mean it does not support all, or even many, of the build options possible when using bjam directly. Although technically you could setenv all the above variables James mentions, and then run configure+make. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo

Thank you, I must admit I had come to that conclusion. When I said "should be possible" I suppose I was expressing dissatisfaction with the extent to which the existing configure script supported the underlying bjam options. OK, I know, "if it doesn't suit you - write your own" ! I realise that the GNU build system is just one out of the many configuations that Boost attempts to support, I just wish it paid more than lip-service to it, since it appeared to build happily under my ARM-configured Buildroot setup ... except that the built libraries were all "arch=i386" ;-) Maybe as more people try to use Boost under the GNU build rather than as a command-line bjam build, this aspect will improve. Time pressures mean I won't be able to do this at the moment, will just have to hack in a command-line bjam build (or set env the lot ?) Regards, Mike

Thanks, I finally got this to build by inserting "GCC=$(STAGING_DIR)/arm-elf-linux" in my $(MAKE) .... all target in the boost.mk file in my Buildroot system. [Though I think I'm going to have to change the toolchain to use "arm-linux-eabi" soon] Had to explicitly state 'arm-elf-linux' so that the unprefixed tool names (e.g. gcc, ld ...) as used by boost build would work OK. Couldn't find an option to prefix 'arm-elf-linux-' to all the toolnames; the above-mentioned GCC and GXX options don't affect the rest of the tools. There ought to be a TOOL_PREFIX option ... Thanks again, Mike

OOPS !! TYPO !! *GCC_ROOT_DIRECTORY* Sorry.
