Bjam problem - again
I've moved to a new machine, and I can run bjam jobs from trunk, but when I try to run sandbox jobs, I am baffled by this message. Unable to load Boost.Build: could not find build system. --------------------------------------------------------- I:\boost-sandbox\boost-build.jam attempted to load the build system by invoking 'boost-build ;' but we were unable to find "bootstrap.jam" in the specified directory Unhelpfully, it doesn't seem to reveal what the 'specified directory' actually is. The files were copied over from a working system, so I can't see what has changed. The jamfile(s) are unchanged. I've got the following environment variables set: I:\boost-sandbox>set boost boost_build_path=i:\boost_1_44_0\tools\build\v2 boost_patches=i:\boost-patches boost_root=i:\boost_1_44_0 boost_sandbox=i:\boost-sandbox boost_trunk=i:\boost-trunk I:\boost-sandbox>bjam --debug_configuration just produces this message. I:\boost-sandbox>bjam -d5 --debug_configuration > debug.log produces the attached log, and the trunk log for comparison. Help! Thanks Paul PS Boost build is undoubtedly clever, but, sadly, not nearly clever enough for the abuse of very many users, judging by the Google entries for the above error message :-( --- Paul A.

You need to either have BOOST_BUILD_PATH set in environemnt, or specified as the argument to the above. Alternatively, you can 1. Go to tools/build/v2 2. Run bootstap.bat 3. Run "./bjam install --prefix=whatever 4. Add whatever/bin to your PATH in this way, no environment variables will have to be set, but then, you'd have to repeat (3) every time Boost.Build is changed in a way you care about. - Volodya

I've changed the environment variables IN UPPERCASE so they are now thus
C:\Users\Paul>set boost BOOST=i:/boost-trunk BOOST_BUILD=I:\boost_1_44_0\tools\build\v2\build BOOST_BUILD_PATH=i:/boost_1_44_0/tools/build/v2 BOOST_ROOT=I:\boost_1_44_0 BOOST_SANDBOX=i:\boost-sandbox BOOST_TRUNK=i:\boost-trunk And everything works as expected. The cause, as usual, was embarrassing simple. bjam os.environ calls are CASE SENSITIVE, whereas Microsoft is 'don't care' <curse> ... </curse>. So showing the environment variables from DOS box was misleading me into thinking I had set them correctly. (jamfiles in boost-trunk didn't use environment variables, so didn't care either...). In retrospect, I might have suspected this sooner, but hindsight is wonderful clear, but "It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so." Mark Twain A warning to use only UPPERCASE might keep others from plopping into this pit. But thanks. Paul --- Paul A.

Paul, is the root directory of the sandbox up to date? A while back I added some better error handling to the boost-build.jam specifically to address inscrutable error messages like this. Also added a readme.txt file which says: This directory contains the file "boost-build.jam" which search for a Boost install as follows: * In a directory specified by the --boost=path command line option. * In a directory specified by the BOOST environment variable. * In the directories ../boost and ../Trunk. In addition the variables BOOST and BOOST_ROOT are set to point to the root of the Boost install, so to refer to other Boost libraries and the main Boost headers, your Jamfile should contain something like: import modules ; local boost-path = [ modules.peek : BOOST ] ; And then you can refer to a Boost library "foo" as: $(boost)/libs/foo/build//boost_foo Note that if your project does not specify a Jamroot file, then a default one is provided for you, and that this file will automatically add $(BOOST)/ to your include path. HTH, John.

OK I've updated and got some more help, but I'm still stuck with os.environ BOOST_ROOT boost-root = Jamfile.v2:30: in modules.load *** argument error * rule path-constant ( name : value + ) * called with: ( local-boost-root : ) * missing argument value I:/boost_1_44_0/tools/build/v2/build\project.jam:1002:see definition of rule 'path-constant' being called I:/boost_1_44_0/tools/build/v2/build\project.jam:310: in load-jamfile I:/boost_1_44_0/tools/build/v2/build\project.jam:62: in load I:/boost_1_44_0/tools/build/v2/build\project.jam:168: in project.find I:/boost_1_44_0/tools/build/v2\build-system.jam:569: in load I:\boost_1_44_0\tools\build\v2/kernel\modules.jam:283: in import I:\boost_1_44_0\tools\build\v2\kernel\bootstrap.jam:142: in boost-build I:\boost-sandbox\boost-build.jam:62: in module scope and tried adding and changing the environment variables so they are now thus C:\Users\Paul>set boost BOOST=I:/boost_1_44_0/ boost_build=I:\boost_1_44_0\tools\build\v2\build << or should this be I:\boost_1_44_0\tools\build?? boost_build_path=i:/boost_1_44_0/tools/build/v2 boost_patches=i:\boost-patches boost_root=i:/boost_1_44_0/ boost_sandbox=i:\boost-sandbox boost_trunk=i:\boost-trunk It seems that boost_root environment variable is not being seen correctly? So I'm doing something wrong still. Thanks Paul
and tried adding and changing the environment variables so they are now thus

It seems that boost_root environment variable is not being seen correctly? So I'm doing something wrong still.
Did you get an error message with instructions before this point? You should need to set just one environment variable: set BOOST=i:\boost-trunk and it'll load Boost.Build etc from that. In addition if you don't have a Jamroot file in your subdirectory then the default one will set up include paths etc for the main Boost tree. Note the upper case name as well boost_root won't be seen by the Build system at all, also use Windows style backslashes for BOOST. Also which directory are you invoking bjam from? HTH, John. PS Just added some more diagnostics to the boost-build.jam file. Also make sure your bjam.exe is up to date... just in case...
