Re: [Boost-users] How to build 32-bit Boost libraries on a 64-bit Linux machine using bjam?

[Gehua Yang]

Hi Folks,

I am using Boost.Serialization and Boost.Thread in my project. Because current Boost release had problems with GCC 4.3, I had to build my own Boost libraries from a svn checkout. Fortunately, with the help from "Getting Started Guide", I accomplished the mission with ease. The commands I used are:
bjam --build-dir=/tmp/build-boost --toolset=gcc --build-type="release <threading>multi <link>static <runtime-link>static" stage
bjam --build-dir=/tmp/build-boost --toolset=gcc --build-type="release <threading>multi <link>static <runtime-link>static" --prefix=/software/boost-20080710 install

The above produced 64-bit libraries. My question is, how I can build 32-bit Boost libraries on the same machine?  Does it take command line variables, such as CXXFLAGS=-m32?


Thanks.

There are two approaches:

1. bjam <.....> address-model=32

This might require SVN HEAD.

2. bjam <.....> cxxflags=-m32

Note this will affect C++ compilation only, add "cflags=-m32" to affect C.

This also requires an architecture option, e.g., 'architecture=x86'.
