Hi there, I am trying to port my heavily Boost-based application to different compiler(-versions) . I was successful with Intel and various Linux-based gcc versions so far. Now I am trying my luck with the Portland group compiler in version 8. Corresponding compiler support seems to be available in Boost: ./tools/build/v2/tools/pgi.jam ./boost/config/compiler/pgi.hpp A "./configure --with-toolset=pgi" succeeds. The subsequent make, however, results in a plethora of error messages such as the following: gcc.compile.c++ bin.v2/libs/math/build/gcc/release/threading-multi/nextafter.o /bin/sh: line 1: -ftemplate-depth-128: command not found -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -pthread -fP IC -DBOOST_ALL_NO_LIB=1 -DBOOST_MATH_TR1_DYN_LINK=1 -DNDEBUG -I"." -c -o "bin. v2/libs/math/build/gcc/release/threading-multi/nextafter.o" "libs/math/build/../ src/tr1/nextafter.cpp" Looking into the pgi configuration files makes it appear as if the pgi support isn't finished yet. E.g. pgi.jam has a commented-out line # flags pgi.compile OPTIONS <threading>multi : -mt ; Indeed, pgCC does not accept this switch: $ pgCC -mt pgCC-Error-Unknown switch: -mt The above error message also makes it appear as if gcc options (e.g. "-Wall -pthread") are passed to pgCC. Can anyone comment on the status of PGI support by Boost ? The above happens on a system whose /etc/redhat-release states "Scientific Linux SL Release 4.0 (Beryllium)". The kernel is 2.6.9-42 . Scientific Linux is a Fedora-derivative, being used mostly in particle physics. Thanks and Best Regards, Ruediger
