when I try to compile and run the gmp-chudnovsky.c file found here with xcode the following errors appear:

I know the gmp library is installed correctly as I have another xcode project linking to it that is compiling correctly. Any ideas as to why this is happening?
Forgot to say I have added paths to the header file and library for GMP as well as add the -lgmp flag under Other Linker Flags
SOLVED: see this answer.
I think xcode runs in a Debug configuration first, where no optimization is performed and no inlining is carried out. This means any inline function must also be made static.

spent some time, with the big help of other SO user, trying to install Allegro library on osx 10.10.5
Finally it seems like it is ok, so I open the code blocks, pasted the example code( http://partitionseven.blogspot.com/2011/01/compiling-allegro-5-with-mac-os-x-snow.html), and I get an error while copiling

when I follow the tutorial exactly running the code from terminal with
gcc alleg5test.c -o alleg5test -L/usr/local/lib -lallegro -lallegro_main
./alleg5test
it works- i got a black screen. But how do I make it work from Code Blocks?

Since you're using AGL, looking at the reference for AGL, you need to import the framework AGL along with OpenGL.
I am trying to test out a few simple Cairo programs, but I am having trouble figuring how to include the source files. I have installed the Cairo library - it's just a question of how to let gcc know...
I have the .h files (including cairo.h) installed in /usr/local/include/cairo
I have the .dylib files installed in /usr/local/lib and /usr/local/lib/cairo
Are there any other components of the installation I should be aware of? (I just did 'make install' to install the library)
I am trying to compile like this:
$ gcc cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/
My cairoTest.c file starts out with:
include <cairo.h>
gcc is finding cairo.h, but it gives the following error message. I think it is not linking to the .dylib files correctly, but I'm not sure. I'm still new to compiling/linking.
gcc cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/cairo

What should I be doing differently to include the Cairo library in my compilation?
Thanks,
Try to compile with
gcc -Wall -g cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/ -lcairo -o cairoTest
(but you probably need other libraries, perhaps thru $(pkg-config --cflags --libs cairo) or similar)
And your file should start with
#include <cairo.h>

have I missed to add some linked libraries?
You can't just call those functions like you would a normal function (they aren't exported by a browser, nor are you linking against a browser); you need to use the function pointers from the NPNetscapeFuncs struct passed to you by the browser.
I'm trying to compile a C/C++ program that uses SDL on a OS X 10.6.8 but I'm having some errors on the linking stage, the code compiles but fails to like due to some missing symbols. The error is:

I checked with the file command and the libraries are either x86_64 only or universal with both i386 and x86_64 versions.
Is there a way for me to determine what exactly is causing this error? A way to check the libs that are being included or any way to help debug the problem?
I don't know if it helps but this is what my Makefile creates, I removed file names to make it short, and the KNT flag is just something I'm using for preprocessor conditions:
/opt/local/bin/g++-mp-4.5 -DKNT=1 -Wp,-M,-MP,-MT,-MF, -std=c++0x -Wall -I source -O1 -funroll-loops -c -o
Thanks.
