digitalmars.D.learn - Executable size when compiling with GDC

Hello everybody.

Today I've tested GDC (on Windows), and a simple Hello World 
program results in a 5 MB exe file, while it's only about 200 KB 
with DMD. Is this normal? What does GDC (GCC?) put in there, to 
make it so big, and why?

Have you tried to strip executable using --strip or --strip-all?

Down to 1 MB, a good start, thanks. I guess that's more bearable.

Lots of symbols and stuff.
You can get it down with -ffunction-sections -fdata-sections  
-Wl,-s,--gc-sections
Phobos should also be compiled with -ffunction-sections -fdata-sections to  
get the whole effect though.

I recall debug builds with MinGW GCC on windows are also enormous. Try release vs debug. -- Dmitry Olshansky
