Hi Paul.

I'm giving up on 1.35 as I've just read about the serialization vector bug, so I'll attempt to use 1.34.1

If you're doing this then be sure to use the current trunk version of Boost Build or at least the version included with the Boost 1.35. release or you might run into 'already solved' build system issues.

The problems described are from Boost 1.35 with bjam v2. I managed to wrangle 1.33.1's bjam v1 to cross-compile, but I could not figure out bjam v2.

I think the key problem is that there seems to be no facility or option to cross-compile, to choose the target platform...

The facility exists, but I'm not sure how well-developed it is at this point. I suggest posting about this problem on the boost-build list. -- Dave Abrahams BoostPro Computing http://www.boostpro.com

Paul, Indeed, cross-gcc nags about the -pthread option. I did not use the resulting libraries in multi-threaded code. In single-threaded they work. I compiled it on linux-mingw on Fedora 8. Rgds, Mikko Paul wrote:

Hi Mikko,

I saw this post, it was useful to get me started in the right direction, but it did not work because it wanted to use pthreads instead of mthreads. using the -d+2 flag to see what was happening ...

"/home/paul/mingw/bin/mingw32-g++" -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -pthread -DBOOST_ALL_NO_LIB=1 -DNDEBUG -I"." -c -o "bin.v2/libs/test/build/gcc-mingw-3.4.5/release/link-static/threading-multi/unit_test_log.o" "libs/test/src/unit_test_log.cpp"

mingw32-g++: unrecognized option `-pthread'

did you compile it on windows-mingw or linux-mingw ?

cheers Paul

Hi Paul,

Please see a previous post on this list: http://lists.boost.org/boost-users/2008/04/35614.php

Hi,

I find the bjam documentation and configuration files very frustrating... it seems to almost do what you want, but it doesn't finish the job and tell you how to actually do it correctly.

I have been trying to cross-compile boost 1.35.0 for windows, on a linux host. The gcc.jam file mentions cross-compiling, but does not mention how to get it done.

I almost got it to work with a user-config.jam: using gcc : mingw : /home/paul/mingw/bin/mingw32-g++ : <flavor>mingw32 <root>"/home/paul/mingwj/" ;

and then hacking away at the gcc.jam file, which checks the os.system variable to decide how to link object files and use the -fPIC flag...

around line 703: if [ os.on-windows ] change to... if [ modules.peek : UNIX ] to force it to use -mthreads instead of -pthreads

if [ os.name http://os.name http://os.name ] != CYGWIN && [ os.name http://os.name http://os.name ] != NT change to if [ os.name http://os.name http://os.name ] = CYGWIN && [ os.name http://os.name http://os.name ] != NT to correct -fPIC

it almost did the right thing, except for the extensions... i assume if i hack these lines, I'll get what i want...

type.set-generated-target-suffix STATIC_LIB : <toolset>gcc <target-os>cygwin : a ; type.set-generated-target-suffix IMPORT_LIB : <toolset>gcc <target-os>cygwin : dll.a ; type.set-generated-target-prefix IMPORT_LIB : <toolset>gcc <target-os>cygwin : lib ;

BUT then I'll have to fight to use the mingw32-ar and mingw32-windres and other programs.

Isn't there an easier way? *please*

I'm giving up on 1.35 as I've just read about the serialization vector bug, so I'll attempt to use 1.34.1

thanks, Paul

Hi Tim, This probably won't work for the same reason highlighted in my reply to Mikko - it will want to link to -pthreads instead of -mthreads, and do various other things because it assumes that because the host computer is linux, that I want to compile for linux. ideas? cheers, Paul 2008/7/1 Tim St. Clair :

If you wanted too... you can also overload all the standard variables for cross compilation and it "should" function properly.

// Rip'd from a script.

export CC=$(TARGET_STAGING_DIR)/bin/$(TARGET_ARCH)-linux-gcc

export CXX=$(TARGET_STAGING_DIR)/bin/$(TARGET_ARCH)-linux-c++ export AR=$(TARGET_STAGING_DIR)/bin/$(TARGET_ARCH)-linux-ar export GCC=$(TARGET_STAGING_DIR)/bin/$(TARGET_ARCH)-linux-gcc export GXX=$(TARGET_STAGING_DIR)/bin/$(TARGET_ARCH)-linux-g++

export LD=$(TARGET_STAGING_DIR)/bin/$(TARGET_ARCH)-linux-ld export NM=$(TARGET_STAGING_DIR)/bin/$(TARGET_ARCH)-linux-nm

then call bjam install

I typically do this during cross compilation, as I don't trust most tools to implicitly "do the right thing". Instead, I explicitly configure an environment where there "can be only one" way to compile.

Then I let the scripts sort it out...

Hope this helps, Tim
