Beaglebone and Angstrom, C++, threads

Hello everyone,

*Note: I posted previously asking my question but I realized I had to fill out the “Categories” after I clicked “POST” and I couldn’t find my original post anywhere so I apologize if this gets posted twice.

I have been having issues with C++ and threads on Angstrom. I currently have the latest Angstrom release for Beaglebone and kernel 3.2.42.

So, I have tried compiling (this example here http://www.cplusplus.com/reference/thread/thread/) with the various combination of -pthread, -lpthread, -std=c++0x, -std=c++11, and I always get this error: “pure virtual method called; terminate called without an active exception;Aborted”, when running the executable.

I looked around and it seems g++ v4.7+ solves this problem so I decided to cross compile for ARM using my Ubuntu Desktop. So, after setting up all the necessary options with ARM cross compilation (using cross compile g++ v4.7.2) on Eclipse, the same issue occurred.

Has anyone gotten threads with C++ to work on Angstrom? If so, or if you have a solution to my problem, could you please direct me to the right direction?

Thank you so much.

Try this, it worked for me

g++ -D__GCC_HAVE_SYNC_COMPARE_AND_SWAP_1 -D__GCC_HAVE_SYNC_COMPARE_AND_SWAP_2 -D__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 -D__GCC_HAVE_SYNC_COMPARE_AND_SWAP_8 -std=c++11 test.cpp -pthread

I dont know where I found this, it was through google searches though.

I got threads to work using the “boost” libraries.
