Hi,

I'm having a hard time trying to use bjam to build boost 1.29.0. I have Win98 in Spanish, and I use Borland C++ Builder 5.0 (its bcc32.exe corresponds to is BCC5.5.1)

I have boost 1.29.0 installed at: "C:\Libraries\boost\Repository\boost"

<snip>

...

If I'm interpreting this output correctly, the problem is that the command line feed to bcc32 exceeds 256 characters.

What can be done about this? Is there a way for 'borland-tools.jam' to put the bcc32 parameters in a tmp response file and use: bcc32.exe @tmprsp.rsp?

Any help will be appreciated.

Fernando,

Unfortunately, bjam is somewhat limited by the underlying shell used to actually run the build commands. We've had a hard time getting it to cooperate with Win9x for that reason. John Maddock has had some success by building and running bjam under Cygwin, which has no command-line length limitation. I'm not sure whether it can be made to run the Borland toolset that way or not, but I know that John targets Borland so it's a good bet.

OK, this might work... thank you. The only problem is that the cygwin-bjam that I've just downloaded from: http://www.boost.org/tools/build/index.html#Jam yields an Access Violation when executed from within my cygwin installation. My cygwin bash.exe it's version 2.04.0(1)-release. Do you know if I require an updated version of cygwin, or is there a problem with the bjam executable? TIA, -- Fernando Cacciola

I don't know, but rebuilding bjam within cygwin is as easy as

make CC=gcc

from within the tools/build/jam_src directory.

Good. John said it won't work for Win32 executables, but it seems that it will work for cygwin-based apps; I might find a use for that. Thanks, -- Fernando Cacciola

If John could explain what the problem is (he mentioned absolute paths, but Boost.Build doesn't really use absolute paths so I'm still a bit confused), maybe a small tweak could be applied to fix it up.

I don't think that a small tweak will be enough: bjam -sTOOLS=borland -d2 regex ...found 526 targets... ...updating 83 targets...

There are two issues here: the boost include path is always an absolute /cygdrive/d/.. path whatever I do with BOOST_ROOT, and the SUFOBJ SUFLIB etc are all set wrong. John Maddock http://ourworld.compuserve.com/homepages/john_maddock/index.htm

You shouldn't be touching BOOST_ROOT. Where does this /cygdrive/d/ business come from? When I build using a cygwin bjam there are no absolute paths.

I don't know where it comes from! BOOST_ROOT is unset when I invoke bjam, but internally bjam is setting it to an absolute path: /cygdrive/d/boost/develop/boost. I haven't been able to override this.

...

and the SUFOBJ SUFLIB etc are all set wrong.

That's easy enough to work around on the command-line with

-sSUFOBJ=.obj -sSUFLIB=.lib

Or you can do it in the environment.

Granted, but it's a pain to have to do this, and obviously newbees won't know anything about it... John Maddock http://ourworld.compuserve.com/homepages/john_maddock/index.htm

BTW: Does *anyone* build all of boost under Cygwin with "gcc -mno-cygwin"? I have so much trouble with this that I think I must be the only one trying to do it. Greg Silverman --- In Boost-Users@yahoogroups.com, "silvermangbs" <silvermangbs@y...> wrote:

Things have changed since 18 Oct 2002, when I wrote that. The instructions for rebuilding bjam are at: http://www.boost.org/tools/build/jam_src/index.html#installing If you're going to invoke it from within cygwin, you want the "Unix type platform" instructions.

Running configure should generally not be needed, especially for well-supported platforms like Windows. I certainly built the threads library using gcc-nocygwin without doing any config steps. I'm very surprised that you needed to do it.

At one stage that did work, but not any more, the cygwin build will only build cygwin apps (it's a problem with the way in which cygwin passes absolute paths to the programs it spawns).

I see. Pity.

You can probably build all you want from the IDE pretty easily - many people do that all the time.

Yes... I've been doing this all the time, but rather because I didn't take the time to learn how to use the build system. At least now I know how to interpret jamfiles, so I guess it will be easy to 'port them' to Borland makefiles. Thanks, -- Fernando Cacciola
