1. Compressing executables.

Hi
I see that UPX is already used when binding Windows executables.
I find that gzexe does an excellent and similar job in Linux eg Jetvet down from 4.4 megs to 1.3 megs

How does that compare to upx on Linux? I would be curious to see a benchmark that tests both compression % and also uncompressing speed.

Hi
As far as I'm aware, pretty favouarably. The reason I used it instead of upx, was because bound executables didn't run with upx, but startup times are perhaps a 1/2 second slower at most (vs unbound), which for the size of the program is fine. Main benefit is quicker inter surgery transfer speeds of the program via ftp. Apparently its giving me 69% compression (though not sure of the calculation)

Chris:
Are you using the latest version of upx upx307 ? It has many options and has versions for many platforms. For windows try upx --best --strip-relocs=0 followed by the filename. The --strip-relocs=0 means DO NOT STRIP OUT RELOCATION INFORMATION .

Hi
I tried compressing a bound windows executable with upx, which reported that the exe was already compressed - I suspect that eui.exe is already compressed with upx. Upx compressed executables wouldn't work on Linux, hence the finding of gzexe.

upx is available on Linux.

Yes, but if you use that to compress a windows executable, it still won't run on Linux ;)
(OK, maybe on Wine, but then it wouldn't half be as funny)
