Compilation fails during linking unit_tests on ARM #430

Closed sinaaghli closed 4 years ago

sinaaghli commented 4 years ago

I'm trying to compile cppzmq on RPI3 and it fails to link unit_tests, here is the compilation output. Any feedback is appreciated

After some more searching, I found that "apt" version of libzmq (libzmq-dev & libzmq3-dev) cause this problem. I installed a local version (specifically tags/v4.6.0) and it compiled fine.

Just for future reference.

I addressed these linking problems when libzmq was built without draft APIs, while cppzmq was being built with them enabled. I don't think it is related to the platform/architecture, but IMO it may be that pre-built packages from distributions are built with default options and so without draft APIs.

In particular, the default value for the option ENABLE_DRAFTS in cppzmq is detected with this snippet of code https://github.com/zeromq/cppzmq/blob/18db4568f9ff1568193d3a496d87bed4bc9ec59e/CMakeLists.txt#L29-L33 so, if cppzmq source directory is a cloned git repository, draft APIs are enabled by default.

The solutions I see are either

It may be worth pointing out this option in the README.

Hi.I'm new to cpp. Could you tell what command you use to install that local version?thanks

so, if cppzmq source directory is a cloned git repository, draft APIs are enabled by default. The solutions I see are either

  • build libzmq with ENABLE_DRAFTS=on (in cmake, for autotools the equivalent is --enable-drafts)
  • build cppzmq with ENABLE_DRAFTS=off (if draft APIs are not needed)

It may be worth pointing out this option in the README.

thanks!!problem fixed
