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?

Given a very simple fortran (95) function and a very simple c++ call to the program, I should be able to compile the program using:
g++ -c main1.cpp
gfortran -c test.f95
g++ main1.o test.o -o run
However, here I get the following error:
ld: warning: object file (test.o) was built for newer macOS version (11.5) than being linked (11.0)

Here, adding a -v tag before the -o tag and after the -o tag and the exe run did not solve the problem, as suggested by the error message.

I went to http://www.linuxfromscratch.org/blfs/view/svn/server/apache.html
From there I found two dependencies Apr-Util-1.5.4 and PCRE-8.40.
I configure the build of apr-util with:
./configure --prefix=/usr/local/mac-dev-env/apr-util-1.5.4 --with-apr=/usr/local/mac-dev-env/apr-1.5.2 --with-openssl=/usr/local/mac-dev-env/openssl-1.0.2k --with-crypto
Most important was to build apr-util with --with-openssl=/usr/local/mac-dev-env/openssl-1.0.2k --with-crypto.
I then built pcre-8.40 as I had been attempting to build with pcre-8.39.
I believe the root cause was not building with apr-util-1.5.4 with the --with-openssl=/usr/local/mac-dev-env/openssl-1.0.2k --with-crypto options.
My configuration before make for apache-2.4.25 was:
./configure --prefix=/usr/local/mac-dev-env/apache-2.4.25 --enable-so --enable-ssl --with-ssl=/usr/local/mac-dev-env/openssl-1.0.2k --with-apr=/usr/local/apr --with-apr-util=/usr/local/mac-dev-env/apr-util-1.5.4 --with-ldap
I am getting the following errors when I try to compile my C++ OpenGL program in Xcode on Mac OS 10.8...What should I do?

Since you're using AGL, looking at the reference for AGL, you need to import the framework AGL along with OpenGL.

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.
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.
