are you trying to compile ROS2? If so, the current ROS2.repos contains a poco-vendor package, which downloads 1.7.7. The way I managed to compile ROS2 is to unlink poco from brew and install the poco-vendor package.
brew unlink poco
ament build
While this solution works, I am hesitating to close this issue, because I believe that's not a long-term solution.
Please report here on that issue whether this workout works for you or not.

Hi, I met the same problem when I was installing ROS, did you manage to figure it out?
from class_loader.
Tested with @Karsten1987 on a High Sierra Sierra machine with recently released poco 1.9.0. It seems to not be an issue anymore. I'll give it a shot on a Sierra machine and close this if it's resolved there as well
from class_loader.
CI on the ros2 branch for macos (using high sierra) passes as of #106 so I'm going to close this. Feel free to comment if you face ethe issue again and we can reopen

@Karsten1987 Hi. I'm building ROS2 with Clang 6.0/libc++ 6.0 on Ubuntu and also had the same error with package libclass_loader
. My Poco vendor version is 1.9.0. The error message is:
libclass_loader.so: undefined reference to `Poco::SharedLibrary::SharedLibrary(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)'
Have you found a long term solution?
from class_loader.
So the latest master repo definitely compiles correctly with the poco vendor package with clang (osx though).
I haven't tested it on ubuntu with clang and i believe the buildfarm is using gcc on ubuntu.
Are you running into this problem also when compiling with the latest repos file? also make sure that no ros1 components are sourced at compile time, as they could interfere with it.
I try to give it a shot in a docker container as soon as i have some time.
