You can save few kilobytes by stripping MorphOS executables:


Ram Disk:eGame> objdump eGame_MorphOS --headers

This strip command (ppc-morphos-strip) removes sections not required to run this executable. They are useful when debugging and it is good idea keep unstripped executable for debugging purposes.

I have to say I thought AmiDevCpp was already stripping the executables. I can't use your method, so any ideas how I could do it with AmiDevCpp (i.e. GCC) ?

You can pass -s switch to GCC.

I am not familiar with AmiDevCpp but if it includes GCC (i.e. ppc-morphos-gcc) there should be also strip command (ppc-morphos-strip for morphos, ppc-amigaos-strip for os4 and so on).

I guess you are not using makefile?

from amidevcpp right mouse on the project tree -> select project options

in the new window, tab compiler -> select linker

now on the right of the same window select strip executable :D

also you can optimize the executable going in Optimizations (under the "select linker" option)

@itix Quote:

As far as I can tell I *am* already passing -s to GCC. So my first thought is that AmiDevCpp's GCC isn't working correctly.

Quote:

Yes & no. AmiDevCpp automatically creates makefiles for you... but I have my own customised ones, so that I can automate compiling of multiple platforms (and in fact multiple files) in one go.

@raistlin77it Quote:

That appears to add a -s on the linker's parameters (in the automatic makefile).
