macOS GCC 14 installer for Mac OS 10.4 x86

[iMacker20]

Download link: GCC 14

This is an installer for GCC 14 x86. It works on these operating systems:
- Mac OS 10.4
- Mac OS 10.5
- Mac OS 10.6
- Mac OS 10.7

It will create x86 (32-bit software).

This is what comes with the installer:
- cctools
- gcc_select
- gettext-runtime
- gmp
- isl
- ld64
- ld64-97
- libgcc
- libgcc14
- libiconv
- libmpc
- lz4
- mpfr
- xz
- zlib
- zstd
- gcc14

It installed to /opt/local/bin/.
The compiler itself is named g++-mp-14.
It implements C++23 and C++26 features.
This can be shortened to g++ by using the alias command like this: alias g++=/opt/local/bin/g++-mp-14
If you want to make this change permanent, add the above command to your ~/.profile file.

Setup Directions:
Open the Terminal.
Use this command to open the ./profile file: pico ~/.profile
Then add this command to the file: alias g++=/opt/local/bin/g++-mp-14
Use Control-o to save your changes.
Use Control-x to exit the program.

How to use:
/opt/local/bin/g++-mp-14 -o program -std=c++23 main.cpp && ./program

Example:
Save this program to a file called main.cpp and run the command above.

#include <print>

int main()
{
    std::println("Hello from C++23");
    return 0;
}

You should see the output "Hello from C++23".

Enjoy!

@f54da Good idea.

Hi! This is kind of neither here nor there, but how does this work to enable C++23 features? When I built NodeJS 24 for OS X 10.9 a few weeks ago, I had to first patch macports-libcxx in order to get a C++20 standard library, and then set the environment very carefully so it would use that library.

I assume the difference is that I was compiling with clang/libcxx vs gcc, but why is it seemingly easier with gcc? Could I have just used gcc instead to make my life easier?

Semi-separately, will software compiled with this GCC 14 in Tiger work on a vanilla copy of Tiger?

Honestly I think GCC is better than Clang. There are times where using GCC does make life easier. I use a version of GCC that can use C++ 17 features for a program that can run on System 6. Lets see Clang do that.

That is a good question. It is a matter of bundling all the dylib files that binary depends on. Once you do that then you should expect your program to run on a vanilla copy of Tiger.

This command will show you a list of dylib files your program depends on:
otool -L <your program>
