Hi Nim65s, I cannot reproduce this bug. My build compiles and works. Could you provide detailed instructions to reach your situation?

Hi,

I have the following error on build:

CMake Error at /opt/ros/kinetic/share/cpp_common/cmake/cpp_commonConfig.cmake:148 (message): Project 'rostime' tried to find library '-lpthread'. The library is neither a target nor built/installed properly. Did you compile project 'cpp_common'? Did you find_package() it before the subdirectory containing its code is included?

Could you include this patch to fix this boost issue?

I have the same issue.

Just a heads up. For this to compile with newer boost (tested with 1.67.0-4) without the bt::microseconds error, it's necessary to manually cast the argument to uint32.

i.e. bt::microseconds(arg) -> bt::microseconds(uint32_t(arg))
