09:04 < DeeKey> mornong!
10:13 < rxr> re
10:17 < DeeKey> rxr: i have modified the /$prefix . I have specified the full path to the prefix dir, which is used in my system.
10:17 < DeeKey> After the compilation some scripts contain this prefix path, which is not valid anymore..
10:17 < DeeKey> Example: prefix= /home/user/t2-trunk/build/build-name/usr
10:17 < DeeKey> Supposed to have in script after the compilation just /usr, not the whole path.
10:17 < DeeKey> is there anything I can do about it?
10:18 < rxr> why do you change the prefix ?
10:18 < rxr> the prefix must only contain the in-system top-level dir
10:19 < rxr> the other stuff, /home/user/t2-trunk/build/build-name is the $root variable of T2 and passed to install targets as DESTDIR=$root
10:19 < DeeKey> if I use default prefix (just /usr) then the system tryes to install the package in my system's root dir!
10:20 < rxr> how do you build it ?
10:20 < rxr> I hope Build-Target ?
10:20 < DeeKey> Yes
10:20 < rxr> ok, which package? a new one ?
10:20 < DeeKey> yes
10:20 < rxr> ok - then the new package probably has no DESTDIR in the Makefile
10:21 < rxr> look if it has something else (like INSTALL_ROOT or so)
10:21 < DeeKey> I will chek it..
10:21 < rxr> T2 has already many workarounds in packages without DESTDIR
10:21 < rxr> just grep DESTDIR package/*/*/*.conf
10:22 < rxr> or you send the package you have so far and I take a look for tips how to make it behave during cross builds :-)
10:23 < DeeKey> ok.
10:25 < DeeKey> what is the requirements for cross compilation?
10:26 < rxr> beside correctly honoring CC, LD and BUILD_CC to use the cross compiler for the files DESTDIR or a-like is required to place the files into the freestanding, new system root
10:26 < rxr> this is not that much actually
10:27 < DeeKey> is there are examples/tutorials/docs?
10:27 < CIA-8> rene * r26136 /trunk/package/x86/syslinux/syslinux.desc: * updated syslinux (3.51 -> 3.52)
10:27 < rxr> hm, not really
10:28 < rxr> but I wanted to blog about the top 10 "dont's" of cross compiling
10:28 < DeeKey> there should be at least good example!
10:28 < CIA-8> rene * r26137 /trunk/package/xorg/xf86-video-vmware/xf86-video-vmware.desc: * updated xf86-video-vmware (10.15.1 -> 10.15.2)
10:28 < rxr> actually when you have a normal package it just works in T2 :-)
10:29 < rxr> you only get into this situation if you have an imperfect upstream package ... :-)
10:29 < CIA-8> rene * r26138 /trunk/package/xorg/xf86-input-vmmouse/xf86-input-vmmouse.desc: * updated xf86-input-vmmouse (12.4.2 -> 12.4.3)
10:29 < rxr> of course that is no excuse for providing more documentation
10:30 < DeeKey> I want to make RTAI to cross compile...
10:30 < DeeKey> It has different pathes for various architectures...
10:31 < DeeKey> They must be automatically selested by reading the ARCH variable..
10:31 < rxr> yeah, some other T2 packages have such code as well, if you need inspiration

15:42 < sangriag> just wondering, what is the merit of this project than the compiled distros like zenwalk or arch or debian?
15:48 < rxr> the precompiled are static, nothing to change
15:48 < rxr> t2 can be adapted to the specific needs
15:48 < rxr> to build appliances, hardened servers or embedded systems
15:49 < rxr> t2 not only supports more architecture than even debian, it also support alternative, tiny C libraries, such as uClibC and dietlibc
15:49 < rxr> vital for embedded systems
15:49 < rxr> also embedded systems or systems targetting a non x86 CPU generally require a special built exactly matching the target CPU, etc. etc ..

16:42 < sangriag> thanks rxr, but I will try to go through the documentation. What is the point of entry? How to begin with? Can I compile from my existing installation?
