Subject: Re: really dumb boost build question

Robert,

Did you do 'b2 headers'?

Here's a more complete discription.

My system is an XP with msvc 9.0 installed.  I use cygwin for my shell.  It has installed the command line git as well.  I followed the instruction for cloning the whole of Boost on this machine and selecting serialization library for development.  I use bootstrap.sh to build the local version of b2.

As a test, I invoke

$b2 toolset=gcc variant=debug link=shared test_native_array_xml_warchive >b2.log & 

and things seem to go as expected.  That is, all libraries required for the test build, the test builds, runs and fails - I expect this to happen.

But when I change to the following command line to:

$b2 toolset=msvc variant=debug link=shared test_native_array_xml_warchive >b2.log &

I get a b2.log file which contains in part

every attempt to compile fails in the same way. So it's not finding the boost headers.  In searching for the cause/fix for this I do the following:

$# display current directory

$pwd
/cygdrive/c/modular-boost/libs/serialization/test

$# check value of BOOST_ROOT

$echo $BOOST_ROOT

$# verify that file actually exits

$ls ../../../boost/config.hpp
../../../boost/config.hpp

$# verify contents of file

$cat ../../../boost/config.hpp

Just to be sure I try

$pwd
/cygdrive/c/modular-boost/libs/serialization/test
$export BOOST_ROOT="cygdrive/c/modular-boost"
$echo $BOOST_ROOT
cygdrive/c/modular-boost

$b2 toolset=msvc variant=debug link=shared test_native_array_xml_warchive >b2.log &

with the same results.

What is the best way to get past this?
