Having found out how to build Bjam, I have tried to build the libraries of Boost 1.31.0 for tru64cxx65. I'm only interested in Regex at the moment, so I won't bother you with the problems building other libraries.

When the build gets to this point:

tru64cxx65-C++-action bin/boost/libs/regex/build/libboost_regex.so/tru64cxx65/release/cregex.o

it hangs. I have run into this situation with other large files, and my usual remedy is to decrease the optimization level.

How can I do that? If I can't do it for just this file, I'm willing to reduce the optimization level for the entire library, or even for all libraries. (This is not a platform that I worry about performance; it's just there to support a few vestigial machines.)

A few possibilities... 1. You can disable it for only the regex library if you are willing to change the boost-root/libs/regex/build/Jamfile. You will need to add: <tru64cxx65><*><optimization>off To the requirements section of template-s in that file. 2. You can do it on the command line, but this would apply to all libraries with: bjam "-sBUILD=<optimization>off debug release" etc... And possibly the most flexible options.. 3. Add special variants for your use into the boost-root/Jamrules and build those variants instead of the "debug" "release" defaults. For example you might add: variant bss-debug : debug : <tru64cxx65><optimization>off ; variant bss-release : release : <true64cxx65><optimization>off ; And then build with: bjam "-sBUILD=bss-debug bss-release" -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq
