[zeromq-dev] Cross -Compiling with gcc-3.3.1

[Alex Ramirez]

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!

Thanks,

Alex
