Trying to build Boost: I cannot get bjam

Question

I would like to build boost using two different compilers, MinGW and Visual C++ 2010 Express, using bjam:

bjam toolset=gcc,msvc variant=release link=static,shared threading=multi install

The problem is that I do not have bjam. I could not find it in the Boost directory, and the one I downloaded from somewhere else was a wrong version.

I should be able to build it from the code in Boost, but how? I read that I must launch build.bat from the BOOST_ROOT/tools/jam/src directory, but that directory does not exist !

Thank you!

Update:

I have been able to get bjam with: bootstrap.bat gcc
Then, launching bjam with the previous parameters, I only get libraries for MinGW (.dll and .a).
This is an extract of the error messages I get with regard to Visual C++ 10:

Trying to use:
bootstrap.bat vc100
I get the error: "Unknown toolset: vc100"

With either:
bootstrap.bat vc10
or:
bootstrap.bat mingw
I get: "\Microsoft was unexpected at this time."

Changing project-config.jam did not help.

So, I did a big step forward, but vc10 is not working, yet...

Answer 1

There is a bootstrap.bat in your boost directory. Run it.

It will build bjam automatically (probably using visual c++).

Answer 2

The directory structure in boost has changed in recent version, I think.

The sources for bjam are in tools/build/v2/engine. Run build.sh mingw from that directory using MinGW shell, and it should build bjam.exe and b2.exe and place them in tools/build/v2/engine/ntx86. Copy b2.exe to the boost root directory. You should then be able to build Visual c++ libraries with b2 toolset=msvc.

Hope that helps.
