hi all,

is it possible to compile gnu multi precision library into OS2008?does somebody already compile it?..im just new in the development of software..already installed scratchbox..im planning to do ipsec on the OS2008 using strongswan..to do cross compile i need gnu mp to proceed..

error when i try to compile in scratchbox :

[sbox-DIABLO_ARMEL: ~/gmp-4.2.3] > ./configure

It looks like someone else has been able to do it: http://repository.maemo.org/extras-d...lo/free/g/gmp/

thanks for fast reply..but got error when installing

do you know where i can find step to cross compile application such as strongswan which is for IPsec..i need to use it on the N800..

You really didn't get any errors worth noting there... You just tried to install programs made for an i386 architecture on an armel architecture. Your dpkg line should have been:
And you wouldn't have gotten problems.

As for step-by-step instructions: it's really more of a trial and error process for me. I don't remember the commands off the top of my head, but basically download the debian source, apply the debian patch, and compile with dpkg-buildpackage. It may take a while to get it right, but stick with it and you'll get it...

I'll see if I can get strongswan compiled in scratchbox for you tomorrow, if you can't get it.

thanks man for your help..i try to download source from debian website which is compile for armel..but too many dependencies i guest..sigh..really appreciate if you could help to point me where i should go..thanks again

You're right, there is a long tree of dependencies to satisfy... Unfortunately, due to personal projects, among other things, I can't really get this working right now. Stick with following the dependency trail, and you should get it eventually. However, once you do that, you'll need to make sure that you can install the run dependencies of strongswan.

Alternatively, you can try adding:
To your application manager, and try then installing strongswan, however this could mess up your OS, so don't do this if you're not prepared to have the possibility of having to reinstall the OS. If you do that, just make sure that you don't UPDATE anything, and that you disable it when you're done.

Good luck! Oh, and this link might help you... it's just a small guide of how to extract debian sources and build a package... Nice reference if you forget.
