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_traitsunsigned 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

Hi,
Have been attempting to cross compile libzmq.a for a PowerPC-405
processor which uses the following tool set versions:
gcc 3.3.1
glibc 2.3.2
As expected, have received multiple linking errors relating to
features not available with libstdc++.so.5 (gcc 3.3.1). The
PopwerPC-405 is prepackaged with a custom linux installation that is
provided by a third party vendor. I've contacted them about support
for upgrading to newer versions of gcc and glibc, tough it's likely
this will not be an option.
Has any had any experience/success cross compiling zeromq libraries
with these older toolsets?
Hi Alex,
which features specifically are not available?
