Hey, A simple hello world application has 1Mb in by 64 bit ubunut machine. When I stript it, is has about 750kb. When I build a cross compiler for android (arm), the executable has a asize of about 10MB, stripped about 5MB. That is huge, five times the size on my linux sysem. Why is this? Can I do something about it? Thanks! Nathan

GHC statically links all its libraries by default. If you want a dynamically linked executable, use -dynamic (ensure you have the dynamic libraries built and/or installed though). > When I build a cross compiler for android (arm), the executable has a > asize of about 10MB, stripped about 5MB. > > That is huge, five times the size on my linux sysem. Not sure what you mean by "five times the size on my linux system". What is 5 times larger than what? Static linking is useful when cross compiling, because it means you can just copy the binary over to the target system and run it. Cheers, Simon

He's saying that the size of the android executable (made by his cross compiler) is five time the sive of the equivalent Ubuntu executable (made by, I assume, his system's GHC). The problem is not the size, but the size ratio. -- -- Stephen Paul Weber, <at> singpolyma See <http://singpolyma.net> for how I prefer to be contacted edition right joseph

Ah, I see. Yes, my executables are a similar size. I'm not sure why, I'll try to look into it.

To pass to opt use '-optlo', e.g., $ ghc -fllvm -optlo-adce ... Its documented in the GHC userguide.

A simple hello world application has 1Mb in by 64 bit ubunut machine.
When I stript it, is has about 750kb.
When I build a cross compiler for android (arm), the executable has a
asize of about 10MB, stripped about 5MB.
