Hi Mikko,
Am able to get the zeromq src to compile and link such that the libzmq.a and
libzmq.la files are created in the hidden .lib directory.
Start seeing link failures when I try to link to to the existing libzmq.la /
libzmq.a files. I've attached the console output from the failures I'm
seeing when I try to compile and link the performance package.
The link errors of interest I'm seeing in this example are:
undefined reference to `std::char_traits::copy(unsigned
char*, unsigned char const*, unsigned)'
undefined reference to `epoll_create'
undefined reference to `epoll_ctl'
undefined reference to `epoll_wait'
All these calls appear to link to libstdc++.so.6, and gcc-3.3.1 is only
compatible with libstdc++.so.5.
Any support is greatly appreciated!
Thanks,
Alex
