I try to build C++11-project on OS X Lion (10.7.5) with clang++. All is fine, except one problem with log4cxx: after compiling I get these linker errors:

This is my clang++:
Apple LLVM version 4.2 (clang-425.0.27) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin11.4.2
Thread model: posix
I build project with flags -std=c++11 and -stdlib=libc++. Attempting to build project with Clang 3.2 didn't help.
Moreover, I've tried to install log4cxx library with port or with brew - same errors in both cases.
So what can I do?

I already linking uhd-types to boost libraries using target_link_libraries.
I'm working on a CocoaPod that depends on two other pods i also wrote. Let's say Pod1, Pod2 and Pod3. Pod2 and Pod3 have this on their podspecs:
...
s.libraries 'sqlite3'
...
... this is because both of them use different static libraries that depend on sqlite. That line adds sqlite3 as a linked library ("Linked Frameworks and Libraries" on Build Phases) on their respective cocoapod compilation.
Then, Pod1 has both of those pods as dependencies:
...
s.dependency 'Pod2'
s.dependency 'Pod3'
...
When i try to compile Pod1, this error is thrown:

What are my options? I tried to publish sqlite3 in a separate, shared pod, but it neither of both libraries take it
Make sure that the podspec specifies sqlite3 as a system library dependency:
s.library = 'sqlite3'
I would like to play a bit with the code of MAD-X (Methodical Accelerator Design; http://madx.web.cern.ch/madx/). I must admit that I am a complete newbie to c, c++, compiling, etc.
I downloaded the sources from the Mad-X git repository (https://github.com/MethodicalAcceleratorDesign/MAD-X) to my MacBook pro (2016, Intel) and in a first step I wanted to compile the code without modifications. To do so, I run
make madx-macosx64-gnu
which runs through the compilation process with some warnings, but the linking fails with numerous errors:

*** Compiling madx_ptc_trackcavs.f90

can you give me advice how to compile this? E.g., there are a couple of Makefiles, one for MacOS, but I'm not sure how to use them properly.
Based on Ulrich Eckhardt's comments I ran "make -d --trace", which provides a lot of output, but unfortunately nothing more conclusive on "Undefined symbols..."

Thanks to David Hammen's comments and the link therein:
Link OSX Homebrew Gfortran against libc++
I was able to resolve this:
I searched for all occurrences of "-lstdc++" in the files and found hits in the following files:
linker.g95 (no need to edit this...)
linker.gfortran: change line 44 from
LDLIBS += $(if $(call eq,$(OSTYPE),Darwin),-lgfortran -lstdc++ -lgcc
-lgcc_eh -lSystem -nodefaultlibs,)
to
LDLIBS += $(if $(call eq,$(OSTYPE),Darwin),-lgfortran -lc++ -lgcc
-lgcc_eh -lSystem -nodefaultlibs,)
Makefile_lib: change lines 57 and 62 (in the if-clause checking for Darwin = MACOS) and replace -lstdc++ with -lc++ too
Works like a fly :)
When I build cpp protobuf with MACOSX_DEPLOYMENT_TARGET=10.11, then I add protobuf.a and includes in my project, it works fine.
but when I try to add to project protobuf.a which built with `MACOSX_DEPLOYMENT_TARGET=10.8', it generates errors:

PS: My project builds with MACOSX_DEPLOYMENT_TARGET=10.8
How to build protobuf with MACOSX_DEPLOYMENT_TARGET=10.8?
I'm testing Boost.Python and have run into some issues.
I managed to complete the "Hello World" example without a glitch (http://www.boost.org/doc/libs/1_54_0/libs/python/doc/tutorial/doc/html/index.html) - everything compiled and I was able to use the .so properly in Python.
However, as soon as I introduced classes into my test file (http://www.boost.org/doc/libs/1_54_0/libs/python/doc/tutorial/doc/html/python/exposing.html), the compiler started screaming

It seems to suggest that the lib files are not linked, but I've included them in XCode
Am I missing something? Thanks very much!
I found out why. Turns out that I'm using the standard library with C++11 support. To fix the issue, I rebuilt boost using brew as follows
brew -v install --with-icu --build-from-source --with-c++11 boost
