| lool | saeed__: Yup | 13:01 |
| saeed__ | how can cross build kernel package for dove? | 13:04 |
| saeed__ | I tried: CROSS_COMPILE=arm-marvell-linux-gnueabi- CONCURRENCY_LEVEL=3 fakeroot make-kpkg --arch arm --initrd --append-to-version=-custom kernel_image kernel_headers --cross_compile - | 13:05 |
| lool | Don't use make-kpkg | 13:19 |
| lool | saeed__: http://kernel.ubuntu.com/ | 13:20 |
| lool | saeed__: debuild/dpkg-buildpackage -e CROSS_COMPILE=arm-marvell-linux-gnueabi- should work | 13:20 |

| Stskeeps | hmm, Mesa 7.6, anyone know of any plans to enable the GLES1/GLES2 part of it and provide packages? | 14:58 |
| lool | Stskeeps: What for specifically? | 15:05 |
| lool | I think we dont have userspace using GLES ATM; I think Clutter could use it but there are some bugs | 15:05 |
| Stskeeps | lool: in this particular case, building against GLES2 headers and then drop in stuff like SGX | 15:05 |
| lool | Right | 15:06 |
| Stskeeps | (i'm aware there's some potential pitfalls in that) | 15:06 |
| lool | I dont think we enable GLES support in mesa in karmic but I guess we could next cycle | 15:07 |
| Stskeeps | :nod: | 15:07 |
| Stskeeps | then there's also the issue of package naming, like, if it's libgles2-dev and so on :P | 15:08 |
| lool | Looks like we just need to --enable-egl in a separate build | 15:09 |
| Stskeeps | yeah, that was my thought | 15:09 |
| Stskeeps | the effect is being able to do GLES stuff in public and fallback on sw rendering, .. and then be able to drop in GLES libs for your device's chip :P | 15:10 |
| thopiekar | hi | 15:26 |
| thopiekar | is there howto install ubuntu arm on a Nokia Internet Tablet? | 15:26 |
| Meiz_webchat | thopiekar: just create rootfs with rootstock and install Mer hw-support stuff :) | 15:27 |
| thopiekar | thanks, Meiz_webchat | 15:27 |
| thopiekar | does anyone of you know how large the size of the rootfs should be to install it on the flash memory? | 15:41 |
| thopiekar | hmm I wanted to create now a rootfs with rootstock but it uses jaunty.. | 16:47 |
| thopiekar | I created myself a karmic chroot | 16:47 |
| thopiekar | with kubuntu-netbook installed.. | 16:47 |
| thopiekar | is there a way to get that chroot as a rootfs? | 16:48 |

| beyossi | hi, what is the /lib/vfp directory?? , why it is installed on my target? some of my .so files resides there as well as at /lib/ - and they are different. any idea? | 22:33 |
| roxfan | /vfp is probably for binaries compiled with vfp support | 22:36 |
| roxfan | https://lists.ubuntu.com/archives/jaunty-changes/2009-March/007966.html | 22:36 |
| roxfan | related: http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg1395037.html | 22:38 |
| beyossi | Thanks. but i didn't understand why it was added?, why all the files are in different size than the same files in /lib or /usr/lib ? | 22:44 |
| roxfan | probably because they use vfp instructions to speed up floating-point calculation | 22:45 |
| beyossi | well, on my host, when cross-compiling, my libraries were taken from /lib and /usr/lib, but on the target applications use /lib/vfp , I guess this is a good reason for problems. Is there a recommendation what to use? | 22:48 |
| roxfan | um, shouldn't you have a separate tree with libs for the target system? | 22:53 |
| roxfan | you should probably either disable vfp when compiling, or install/crolss-compile vfp libs on the host system... | 22:54 |
| beyossi | actually, on the host I was used a copy of the target filesystem (using relative symbolic links) and pointing the LIBDIR to either /lib or /usr/lib. But then when executing on the target the application was loading the libs from /lib/vfp... | 22:57 |
| beyossi | can I be sure that every library installed in /lib or /usr/lib is also installed in vfp ? | 22:57 |
| roxfan | i think it will fall back to /lib if it's not found in vfp... | 22:58 |
| beyossi | so i need to define both paths for linking?, is there a way to define it with priorities?. I have to say that this issue sounds not convenient at all. i will try playing with that... | 23:01 |
| roxfan | maybe try running the program with LD_HWCAP_MASK=0x0 and see if it helps | 23:02 |
| lool | beyossi: We built two passes of glibc in jaunty | 23:04 |
| lool | One for vfp and one for non-vfp | 23:04 |
| lool | The versioning between the two on an installed system is very strict | 23:04 |
| beyossi | lool: for example, libdl.so.2 is taken from the /lib/vfp library (monitoring using ldd), while the same file name exist at /lib/libdl.so.2 - the libdl.so is at: /usr/lib/libdl.so and it points to ../../lib/libdl.so.2 . so i don't understand why the program is using /lib/vfp | 23:12 |
| roxfan | black magic | 23:20 |
| roxfan | i guess ld is checking hwcaps and adding /vfp to search path if hardware supports it | 23:21 |
| beyossi | but as far as I understand, a program will look for libdl.so (which exists only once) and not directly to libdl.so.2, and my libdl.so points to a specific place | 23:23 |
| beyossi | btw, I renamed library /lib/vfp to /lib/vfp2 and then everything points back to the 'old places' - latter on I will try building my entire target with the vfp | 23:27 |
| beyossi | Thanks for your help | 23:27 |
| beyossi | Another issue I face is related to executing QT on my beagleboard which has a PowerVR GPU. after executing the app it fails with: "powervr: driver not found", does anybody know what drivers it looks for exactly?, anyway to debug it? | 23:32 |
