Maybe. First tell me what the output is from the messages that process_jam_log outputs soon after it starts. The lines that create the messages begin about line 366 in the source file:
std::cout << "boost_root: " << boost_root.string() << '\n'
<< "locate_root: " << locate_root.string() << '\n';
prompt$ ../tools/regression/build/bin/process_jam_log/cray/release/ process_jam_log
Usage: bjam [bjam-args] | process_jam_log [locate-root]
locate-root is the same as the bjam ALL_LOCATE_TARGET
parameter, if any. Default is boost-root.
boost_root: /u/ph/troyer/boost
locate_root: /u/ph/troyer/boost
I thus added $boost_root to the command. Was that unnecessary, since as the output shows it seems to find boost_root? In that case I am confused why it prints a usage message.
