Hi everyone, I downloaded and built bjam-3.17 under linux x86_64 (RHEL 4.6). I then built boost 1.40.0 using following command line: ../boost-jam-3.1.17/bin.linuxx86_64/bjam --build-dir=/tmp/build-boost-1_40_0 stage --build-type=complete --layout=tagged My user-config.jam has just been modified so that the toolset used is gcc4.2.3. I got following warnings in the math library: gcc.compile.c++ /tmp/build-boost-1_40_0/boost/bin.v2/libs/math/build/gcc-4.2.3/release/l ink-static/assoc_laguerrel.o libs/math/build/../src/tr1/assoc_laguerrel.cpp:6:21: warning: /tmp/build-boost-1_40_0/boost/bin.v2/libs/math/build/gcc-4.2.3/release/l ink-static/../src/tr1/pch.hpp.gch: created and used with different settings of -fpic gcc.compile.c++ /tmp/build-boost-1_40_0/boost/bin.v2/libs/math/build/gcc-4.2.3/release/l ink-static/assoc_legendrel.o libs/math/build/../src/tr1/assoc_legendrel.cpp:6:21: warning: /tmp/build-boost-1_40_0/boost/bin.v2/libs/math/build/gcc-4.2.3/release/l ink-static/../src/tr1/pch.hpp.gch: created and used with different settings of -fpic gcc.compile.c++ /tmp/build-boost-1_40_0/boost/bin.v2/libs/math/build/gcc-4.2.3/release/l ink-static/betal.o [snip lots of them] Then the serialization library reports following warnings: gcc.compile.c++ /tmp/build-boost-1_40_0/boost/bin.v2/libs/serialization/build/gcc-4.2.3/ release/link-static/xml_grammar.o In file included from ./boost/archive/impl/basic_xml_grammar.hpp:59, from libs/serialization/src/xml_grammar.cpp:16: ./boost/spirit/core/non_terminal/rule.hpp:18:4: warning: #warning "This header is deprecated.

To: BOOST Archives

I just got1.40and tried building. I kept having some pieces fail with a complete build, sometimes I had gcc that ran until resources exausted, sometimes the compiler would segfault. Eventaully I tracked it down to the math library. After noticing the many errors from the gch (things like : error _REENTERANT not defined or used diffrent -fpic). I disabledpchfor the math library (actually the boost project and the libs/math/test) and I did not have any more issues.

Can you be more specific about the error messages? A: bjam --with-math will build just the math lib, if you could post the complete output that would be most helpful. There's something strange going on here though as it builds just fine locally here (ubuntu Linux), and on our regression test machines (various Linux flavours). Thanks, John. JOIN US FOR THE JOURNEY.
