RE: Huge executable file with gcc version 3.1.1

[Douglas Richardson <douglas dot richardson at gaussvip dot com>]

You are probably statically linking with the runtime libraries. Look at the
output of gcc -v. It will tell you how your gcc was configured. Do you see a
--disable-shared anywhere in the output? If so, you are statically linking
with the runtime libraries.

Subject: Huge executable file with gcc version 3.1.1


Hi,

I found that even very small test cases like an Hello World Program in C++, 
creating huge executable files for h8300-elf architecture.

If you see the output from the shell given below, 
you find that for a simple program, the executable was 2.9 MB.

I noticed this happening only when some header file was included.
This causes the simulator to crash, and when I compiled with -g option,
and tried to load it on the debugger, I found the debugger crashing when 
I tried to load the executable on the simulator.Seems the debugger crash 
must be due to this large size.

I noticed this when I found many test cases failing when I ran make check.

Any help would be appreciated.

Thanks and Regards,

Venky
