boost builds but does not run

[steenparl@…]

I am trying to get boost on my mac. I have had it before, but it is not working. The Macports almost works, though. I have executed the following:

sudo port self update
sudo port upgrade outdated
sudo port install boost

It builds, but running the simple attached program using boost threads hangs with what looks like an invalid address (0).

Simple C++ test on xCode 4.6, OS-X 10.8.2. No log file

No log file

Even if it doesn't create one automatically, if you're compiling it from the command line, you can always redirect the output to your own log file, or pipe it through tee, or something else like that

The log file from the install boost

Hi, I attached the log file by redirecting as you suggested.

In the future, please use WikiFormatting and Cc the port maintainer(s).

Works just fine for me with both

/usr/bin/clang++ -I /opt/local/include -L /opt/local/lib main.cpp -lboost_thread-mt -lboost_system-mt -o main

and

g++-mp-4.7 -I /opt/local/include -L /opt/local/lib main.cpp -lboost_thread-mt -lboost_system-mt -o main

or

/usr/bin/clang++ -I /opt/local/include main.cpp /opt/local/lib/libboost_thread-mt.a /opt/local/lib/libboost_system-mt.a -o main

and

g++-mp-4.7 -I /opt/local/include main.cpp /opt/local/lib/libboost_thread-mt.a /opt/local/lib/libboost_system-mt.a -o main

Can you run your test program under the debugger (either gdb or lldb)?

You might want to add the -g debugging flags to the compilation of main.cpp for that. You should not need to install the debug variant of boost!

Thank you for that. I copied your lines and they both work for me, except for the "-mp-4.7" which my system doesn't seem to recognize. This shows, I assume, that the macport is fine and the problem I am having must be in xCode, where I still have the problem. Thanks again for your help.

[adfernandes (Andrew Fernandes)]

The "-mp-4.7" denotes the MacPorts gcc compiler.

Thanks for letting me know!

One thought - boost has problems with 32-bit builds due to the atomic operations. So if you have universal builds or are running a 32-bit executable, that might be the problem.
