Larger size with Mingw

[sudip]

Hello Master Roberto,
Thanks a lot for your reply and for strip.rar. It works fine

I'll include it and do by default from the next test release.

Thanks a lot again
With best regards.

It's amazing !!!!

File Exe original = 5.423.293 bytes

With Strip.exe = 4.9216.224 bytes
and next with upx.exe = 1.380.352 bytes -> 25.45 %

if compress with only upx.exe = 1.887.421 -> 34.80 %

Thank's Roberto

And second thoughts ... If you compile a

Code: Select all

function main()
? "Hello world !" 
Return

in mode console, Harbour generates an exe of 1,136,095 bytes. This is because the routines or libraries are loaded, which are never used in this case for example the RDD, printer system, etc. and will therefore generate large exes.

Question : With Ide.exe or buid.bat, Can we select the libraries that are to be in the exe?

Thank's ( and to google too, for the english translate )

Hi Claudio,

I think this we had discussed already.

As regards the number of library files with IDE and Build.bat, we need not worry about. Because, only the required libraries are linked.

Moreover, you could try the following (I've not fully tested yet).

In 'build.bat' 'hbmk2' line (#170) you could add the following:

Code: Select all

-cflag=-Os

That will send the flag '-Os' directly to MingW (gcc compiler).

'-Os' means 'optimize for size'. I've tested with various samples without any effect. Anyway, I guess that it will work in some special circumstances.

If you prefer speed instead size, you cold use:

Code: Select all

-cflag=-O3

A complete list of gcc optimizations is here:

Enjoy!

And... if you are a patient man and have a very very very speedy PC you could try:

Code: Select all

UPX --ultra-brute yourapp.exe 

Good luck!

Code: Select all

UPX --ultra-brute yourapp.exe 

It reduced HMG's 'hello world' to 512512 BYTES!!!
