Re: Possibility to porting Rsync to NT and other platforms
Did you try compiling your java code to native machine code, with gcj http://gcc.gnu.org/java/ ? Le 19 mai 09 à 05:26, Hasanat Kazmi a écrit : I want to embed it into a program. So putting in these two will create licensing issues for me. Any guide of those specif portions of code where it makes system calls? I have ported rsync to java (I used same rolling algorithm but used other hashing) but it isn't fast enough, seems I have to make a native binary version.

Re: Possibility to porting Rsync to NT and other platforms
Well, in this case it seems clear to me that you will have to rewrite rsync entirely, keeping the delta algorithm and network protocol... Such a huge work! Good luck.
