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<unsigned char>::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!
