I'm following the directions on this page: http://wiki.videolan.org/Mac_OS_X_Framework
I can build the core components, but when I try to build framework I have an error
How can I fix it?

Although more a novice I try to explain my problem.
I am on a Mac and use command line to build the executable. The compiling command works successfully on Ubuntu.
cc program.o file1.o file2.o file3.o file4.o -lm -lrt -o program
ld: library not found for -lrt
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [program] Error 1
If I run with -v command I get the following:
Apple LLVM version 7.0.2 (clang-700.1.81)
Target: x86_64-apple-darwin14.5.0
Thread model: posix

ld: library not found for -lrt
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Any hint?
I found in this post what -lm -lrt mean but still could not figure out a solution.
Update 1: According to this link -lrt is not available for Mac.
Update 2: I have found two possible solutions: (a) either to remove completely the flag or (b) use the -lSystem.B instead. The real-time extensions seems to be in libSystem.B.dylib as explained here.
I have a problem with linking a compiled program (see github repo for details).
The osx specific makefile section is here:
CFLAGS = -v -arch x86_64 -Wall -fPIC -O2 -I./include $(OPTS)
LDFLAGS = -v -arch x86_64 -lpthread /usr/local/lib/libportaudio.a -framework CoreAudio -framework AudioToolbox -framework AudioUnit -framework Carbon
EXECUTABLE ?= squeezelite-osx
include Makefile
The compilation works fine, but during the linking it fails with:
Apple LLVM version 7.0.2 (clang-700.1.81)

ld: library not found for -lFLAC
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [squeezelite-osx] Error 1
The library which is not found is in the folder /usr/local/include and I think I have to add this path to the include path of the linker.
How can I add the path /usr/local/include to the include path of the linker?
The linker doesn't use include files; that's the compiler (actually the pre-processor, but let's keep it simple).
Instead you need to tell the linker that it should look in /usr/local/lib using the -L option:
-L/usr/local/lib
Note: you can provide more than one -L option to the linker.
When I try to build my Xcode project this error comes up:
clang: error: linker command failed with exit code 1 (use -v to see invocation)
It is really frustrating because I cannot get rid of it. It shows up in my normal target and my test target. Please help.
The full error is below thanks.

The library libobjc.A.dylib that you are using don't have an i386 architecture slice. You probably is getting this error when running the app on simulator right?
Compile using a compatible version of your library or try to run on a real device to see if it resolves your problem.
Ok, I'm having trouble building gcc-4.9.2 on Apple's new OS X Yosemite. I'm not sure if I need to be building a gnu-gcc compiler on OS X, as most other software has compiled fine, apart from tesseract-3.0.1 and some of my own wxWidgets applications. Are there certain programs/code features that clang can't compile?
My build steps are as follows:
cd build-gcc
../gcc-4.9.1/configure --program-prefix="gnu-" --prefix="/usr/local/gcc-4.9.1" --with-gmp="/usr/local" --with-mpfr="/usr/local" --with-mpc="/usr/local" CC=clang CXX=clang++
make
My build path and gcc source paths do not contain any whitespace, and I have installed GMP, MPFR and MPC in /usr/local.
My build outputs are:
clang++ -g -DIN_GCC -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -fno-common -DHAVE_CONFIG_H -Wl,-no_pie -o cc1 c/c-lang.o c-family/stub-objc.o attribs.o c/c-errors.o c/c-decl.o c/c-typeck.o c/c-convert.o c/c-aux-info.o c/c-objc-common.o c/c-parser.o c/c-array-notation.o c-family/c-common.o c-family/c-cppbuiltin.o c-family/c-dump.o c-family/c-format.o c-family/c-gimplify.o c-family/c-lex.o c-family/c-omp.o c-family/c-opts.o c-family/c-pch.o c-family/c-ppoutput.o c-family/c-pragma.o c-family/c-pretty-print.o c-family/c-semantics.o c-family/c-ada-spec.o c-family/c-cilkplus.o c-family/array-notation-common.o c-family/cilk.o c-family/c-ubsan.o i386-c.o darwin-c.o \

Thank You in advance for any help.
Turns out that I had a broken ranlib in /usr/local/bin - maybe GNU Binutils don't work on OS X? All I needed to do to fix the problem was to:
sudo mv /usr/local/bin/ranlib /usr/local/ranlib_old
and then make, and now I have a working GCC!
my project blows up with this message:
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I cannot figure out what I am doing wrong. I've taken out all of the offending code (i think), and I've even deleted everything back to the original classes, but I still get the messages.
Any suggestions?
Thanks.

It appears that you have double defined testprop3.
