[Boost-users] [bjam] boost compilation with cxxflags -fPIC

[alfC]

Hi,

Please, can anybody tell me how to compile Boost (e.g. 1.43) with the
-fPIC as cxxflag:

typicially I do

./bootstrap --prefix=$HOME/usr
./bjam
./bjam install

There are some threads that give answers but in none of them it is
clear exactly what is the command we need to write.

I tried with

CFLAGS=-fPIC ./bjam
./bjam cxxflags=-fPIC

and still the result seems not to use -fPIC

Thank you,
Alfredo

You don't need to separate invocations. "./bjam install" will just work.

./bjam cxxflags=-fPIC install

should work (if you need installing). You can add -n to see the command
lines. You can add -a to rebuild everything -- necessary if you have
already did a complete build without -fPIC.

Note that this flag will only make sense for static builds, since
shared libraries are built with -fPIC anyway.
