pgi.hpp and configure script

[wladwig@…]

I ran into several problems trying to build boost with the PGI compiler v7.2-3 and the Boost 1.36.0 library.

1) ./configure --with-toolset=pgi does not correctly use the pgi configuration

Using the ./configure script which comes with the Boost 1.36.0 package does not setup the build system to use the pgi compiler properly. Using the commands "./configure --with-toolset=pgi" and "make install" generates errors which look like (in this case when compiling boost python):

-ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -fPIC -pthread  -DBOOST_ALL_NO_LIB=1 -DBOOST_PYTHON_SOURCE -DNDEBUG  -I"." -I"/home/wdt/Python2.5/include/python2.5" -c -o "bin.v2/libs/python/build/gcc/release/threading-multi/numeric.o" "libs/python/src/numeric.cpp"

...failed gcc.compile.c++ bin.v2/libs/python/build/gcc/release/threading-multi/n umeric.o... gcc.compile.c++ bin.v2/libs/python/build/gcc/release/threading-multi/list.o /bin/sh: line 1: -ftemplate-depth-128: command not found

It looks like it's trying to use the gcc configuration without calling the executable.

2) pgi.hpp does not allow for versions greater than 7.1

I then tried to build the boost python module by calling bjam directly, using "bjam toolset=pgi --with-python". This failed with:

"./boost/config/compiler/pgi.hpp", line 27: catastrophic error: #error

directive: "Pgi compiler not configured - please reconfigure"

# error "Pgi compiler not configured - please reconfigure"

It appears that pgi.hpp is coded to only use v7.1 of the compiler. After I made the change to the header file to use v7.2, it built the boost python library successfully (but with many compiler warnings).

John, assigning this to you as pgi.hpp tweaks are part of Boost.Config.

[John Maddock]

The changes to pgi.hpp are already in Trunk.

Reassigning to Doug Gregor, as I believe he wrote the top level ./configure script?

John.

I do not think Doug is active here, and configure script is likely to be gone for 1.39.
