socket library
by Phil Nash 10 May '02

10 May '02

Hi all, Does anyone know what the state of the socket library is? I remember it getting started sometime last year, and there is an implementation in the files section on Yahoo, but that is far from complete and is all I can find. Has it gone off the boil or is someone still looking after it? Many thanks, [)o IhIL..

Ok. I went back and built bjam and jam from .\tools\build\jam_src. Then I tried: /path-to-jam/jam -sBOOST_ROOT=. sTOOLS=msvc and got: <result> Couldn't find Python 2.1 installation in c:/tools/python skipping Boost.Python library build You can configure the location of your python installation, by setting: PYTHON_ROOT - currently "c:/tools/python" PYTHON_VERSION - currently "2.1" The following are automatically configured from PYTHON_ROOT if not otherwise set PYTHON_INCLUDES - path to Python #include directories; currently PYTHON_LIB_PATH - path to Python library; currently "c:/tools/python/libs" "c:/tools/python/PCBuild" PYTHON_STDLIB_PATH - path to Python standard library modules; currently "c:/tools/python/Lib" D:\dev\boost\tools\build\allyourbase.jam:609: in C++ warning: unknown rule C++-action D:\dev\boost\tools\build\allyourbase.jam:1065: in Object D:\dev\boost\tools\build\allyourbase.jam:1122: in Objects <snip> D:\dev\boost\tools\build\boost-base.jam:1751: in lib libs\thread\build\Jamfile:59: in load-jamfiles D:\dev\boost\tools\build\allyourbase.jam:1580: in SubInclude D:\dev\boost\tools\build\allyourbase.jam:1178: in subinclude Jamfile:3: in load-jamfiles D:\dev\boost\tools\build\bootstrap.jam:15: in boost-build D:\dev\boost\boost-build.jam:2: in module scope ...found 347 targets... ...updating 12 targets...

building Boost using Jam
by jd.schmidt＠juno.com 09 May '02

09 May '02

Hi, I'm new to using Boost. I've been trying to build Boost using Jam on Windows 2000. My compiler is MSVC6 SP5. As the documentation (www.boost.org/tools/build/index.html) says, I went to my Boost root directory (C:\boost_1_27_0 for me) and used the command jam -sBOOST_ROOT=. -sTOOLS="msvc" and I get the message: 'jam' is not recognized as an internal or external command, operable program, or batch file OK, fine, jam.exe is in C:\boost_1_27_0\boost-build; that's just where I downloaded it to. I've tried to run Jam from the boost-build directory, but I get the message: Jamfile: No such file or directory ...found 8 targets... This doesn't seem very straightforward. What do I need to do here so that I can build Boost? ________________________________________________________________ GET INTERNET ACCESS FROM JUNO!

build setup - what have I missed?

This worked once. Then the [yeah, it wasn't backed up] disk drive died. Target system is Win2000, SP5 and MS Visual C++ 6.0, SP5. Downloaded boost-build.win.zip and extracted it to c:\bin\boost-build. Added c:\bin\boost-build to the path. Set environment variables: BOOST_BUILD=c:\bin\boost-build JAM_TOOLSET=VISUALC VISUALC="c:\Program Files\Microsoft Visual Studio\VC98\bin" Checked out from CVS to d:\dev cd'd to d:\dev\boost and executed: %BOOST_BUILD%\jam -sBOOST_ROOT=. -sTOOLS=msvc <result> warning: unknown rule boost-build don't know how to make all ...found 1 target... ...can't find 1 target... </result> I've clearly screwed something up but I can't figure out what. Help would be appreciated. TIA (from the eternal newbie)

Unable to compile Boost Graph (BGL) inVisual Studio 7 (.NET)
by dmarsh26us 08 May '02

08 May '02

Have just bought the book and downloaded the source it all looks cool.... BUT Can't build a thing! Managed to get hold of AllExamples.dsw eventually converted it to a new VC7 solution ok (few errors on some projects). But no builds, cannot build any of my own code with BGL either. HELP. This is the jist of it:- ------ Build started: Project: dfs_example, Configuration: Debug Win32 ------ Compiling... dfs-example.cpp ../boost_1_25_1\boost\type_traits\cv_traits.hpp(188) : fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 2844) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information Build log was saved at "file://c:\BGL\VC++ Projects\Debug\BuildLog.htm" dfs_example - 1 error(s), 0 warning(s) ---------------------- Done ---------------------- Build: 0 succeeded, 1 failed, 0 skipped The cv traits class seems to trigger the compiler to crash horribly. I don't even know what this class does yet. (only got to page 55 of the book!) Anyone know a workaround? Anyone tried VC7 with boost yet? Is there a microsoft patch yet? Can't go back to VC6 as am using other new libraries. Thanks David Marsh

Help me pay the piper?
by dick.bridges＠tais.com 08 May '02

08 May '02

Now that I've used all this swell stuph, it's time to pay the piper: turn it over to QC and get it into "The Build". Unfortunately the QC people would like some instructions that describe which version of boost-build I'm using; how to install it; which version of the libs I'm using; etc. <some background> It's been a couple of months since I started with the boost libs, and I don't remember all the gyrations I went through to get it working and I'm POSITIVE I did a LOT more than is required. I remember that, after downloading and extracting boost_1_27_0.tar.gz, I had to get the current version from CVS before I could get a clean compile. (I tried turning over copies of my disk drives to them but it turns out that is not considered acceptable documentation. %>[ ) I've been following the jamboost and Boost-Users mailing lists so I know there've been quite a few changes - especially to boost-build. After building a "clean" testbed machine, I started by downloading boost-build.win.zip and following the instructions in the readme.html. Well, that didn't work. I can do a hand job on the path but I'm not sure what environment variables are actually required. Current plan is to pull the library source directly from CVS. Problem is, I don't know what version to tell QC I'm using and, unless all the folks at boost.org would agree not to add anything to CVS for a while, I SURE can't tell them how to re-create what I did. ;) </some background> I can always take what I've got; check it in and call it a day but that's not the path to getting boost integrated into the development environment around here. (Hey, I'm trying to be an evangelist here.) Anyone by any chance working on some updated instructions and/or docs that maybe aren't ready for prime time but would be willing to share? TIA PS: Current target systems are Win2000, SP2 and Visual C++ 6.0, SP5 and vanilla Red Had Linux 7.2.

voronoi diagram and BGL

Hi, Is it possible to order the edges of a vertex of a boost graph? >From what I can glean from the BGL documentation, I guess the answer will be "No, but may be some time in the future". I so, how soon in the future? Thanks, Louis.

Solaris jam build
by cs_jritchie 08 May '02

08 May '02

I am receiving the following on a Solaris system when using: jam -sBOOST_ROOT=. -sTOOLS=gcc status/Jamfile:53: in failed-test-file warning: unknown rule FAIL_EXPECTED status/Jamfile:100: in fail-to-build ./tools/build/boost-base.jam:1407: in subvariant-target ./tools/build/boost-base.jam:1448: in main-target ./tools/build/boost-base.jam:1065: in declare-local-target status/Jamfile:35: in boost-test status/Jamfile:119: in compile-fail status/Jamfile:368: in SubInclude ./tools/build/allyourbase.jam:1141: in subinclude Jamfile:5: in module scope {...above repeated many times...} Unable to load Boost.Build, it seems that the build system files were located, but the build system is not defined. Attempted to use, as the bootstrap, this file: ./tools/build/boost-build.jam. This means that even though that file was loaded it either failed to directly load the build system files, or it failed to specify where to find and load the files by calling the 'build-system [path] ;' rule. Please consult the documentation at 'http://www.boost.org'. What am I doing wrong? Any help is appreciated.

Re: Problems building Python lib

Sorry -- Newbie here -- I don't know exactly what the 'latest CVS state' is or how to get it. I have been trying to build boost-python on Windows95 with MSVC++6.
