Title: Why is my Hello C++ program 6 MB big?
Post by: kaarlo52 on January 03, 2024, 08:46:14 AM

Why is my Hello C++ program 6 MB big?

I installed Windows cross-compiler adtools on Cygwin.

And compiled simple c++ program:

"ppc-amigaos-g++ -athread=single helllo.cpp -o hello"

At least it works.

Here are the instructions:

I had to use Hyperion SDK 53.30 in native-build makefile SDK_VERSION to build it.

Could it be that to make this a stand alone executable, extra stuff has to be compiled into the program? So that any system can run it? Not done any C coding. But seem to recall back in my PASCAL coding days that this was a thing when you compiled.

I've never buildt for OS4 (I think), so I don't know if this is relevant, but... have you tried "strip hello" to remove the symbol table etc?

ppc-amigaos-strip.exe worked. Now the executable size is 690 KB.

Thanks.
