undefined-symbol

I have a bit of a dilemma — no matter what I do, I cannot get Apple's Instruments.app to symbolicate any of the included instruments while I'm profiling on my devices (it works OK in the iOS Simulator). I've tried just about everything I can think of, including: Checking that I'm actually building a dSYM Switching between Debug and Release build schemes Making sure that the signing certificate being used in my Development cert Adding and removing my Derived Data folder from Spotlight's Privacy list Clean & Build before profiling Removing the Derived Data folder before building and profiling I

I am running through Apache's Thrift tutorial: http://wiki.apache.org/thrift/ThriftUsageC%2B%2B My Thrift is version 0.9.1, and I'm on OS X. I've performed a search for similar problems with this tutorial, and while other people have also had issues they don't appear to be similar to the one I'm having. The server both compiles and links properly, and the client compiles correctly as well. The problem is linking the client at the very last step of the tutorial, where I get this: Undefined symbols for architecture x86_64: "apache::thrift::transport::TSocket::TSocket(std::string, int)",

I'm trying to compile a kernel module (which I wrote myself) on a raspberry pi. I am compiling it in the target environment. I get the following output: make -C /lib/modules/3.12.23-1.20140626git25673c3.rpfr20.armv6hl.bcm2708/build M=/home/harmic/horus/ppminput modules make[1]: Entering directory `/usr/src/kernels/3.12.23-1.20140626git25673c3.rpfr20.armv6hl.bcm2708' CC [M] /home/harmic/horus/ppminput/ppminput.o Building modules, stage 2.

My project consists of a couple of static libraries, which are linked together in a final step. Now I have the problem, that the link order of the library is important (otherwise I get an undefined symbol linker error). Sometimes I run into the problem, that I have to re-sort the linked libraries (-lcommon -lsetup -lcontrol etc). At the moment it's a stupid trial and error: re-sort, compile, check error, re-sort, compile and so on. So I wrote a small program to show me the inter-library-dependencies and generates me the order of libraries to link. It reads in the defined ('T', 'B', etc) and

I've got a c++ program I'm trying to wrap/convert to Cython. It uses a particular library that for some reason, will not result in a working module for importing. There is a working c++ program, by the way. Here's the setup.py: ext_modules = [ Extension( name="libnmfpy", sources=["interface/nmf_lib.pyx"], include_dirs = ["../src/", numpy.get_include()], libraries=["nmf","mpi_cxx","mpi","m"], library_dirs=["../build/Linux/bin.release","/usr/local/lib/","/usr/lib"], language="c++",) ] setup( name = 'libnmfpy', cmdclass = {'build_ext': build_ext}, ext_modules = ext_modules, ) I should mention it
