ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
other boost libraries (system, thread, filesystem) work well. is there something wrong with my linker flags? build system? installation?
Edit: I also tried using clang++ as suggested, but I get similar errors:
$ clang++ -I/opt/local/include loggertest.cpp -o loggertest -L/opt/local/lib -lboost_log-mt -lboost_log_setup-mt

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Edit: solved by compiling with -DBOOST_LOG_DYN_LINK as suggested by #neverpanic

Answer 1

You are experiencing a standard library mismatch. Boost from MacPorts (and all other libraries from MacPorts and on modern OS X since 10.9, I think) are built against clang's libc++, rather than gcc's libstdc++. If you attempt to mix both standard libraries, you'll run into this problem (which is a good thing, because if you wouldn't see this, you'd likely see hard to debug crashes at runtime).
You need to use clang++ instead of gcc to compile your code. Alternatively, you can use /usr/bin/g++, which is nowadays a symlink to clang.
