| 00:20.56 | pierrelux | I was wondering, what if I choose to pick up, say kernel 2.4.31, headers in "toolchain option" when the running kernel on target device is different (2.6.5) ? |
| 00:28.21 | CosmicPenguin | I have absolutely no idea what you just said |
| 00:32.13 | pierrelux | I'm using buildroot. "make menuconfig" than in "Toolchain Options" and "Kernel Headers", there's only choice for a limited number of kernel. My question is: is it a problem to run a kernel (in my case 2.6.5) different than the one used to build the toolchain (I mean, the headers). |
| 00:32.28 | pierrelux | is that clear ? |
| 00:35.10 | CosmicPenguin | that is clear |
| 00:35.18 | CosmicPenguin | the kernel on your system has absolutely no effect on the kernel you are compiling for |
| 00:37.54 | pierrelux | well, I'm talking about the kernel on the target system based on 2.6.5 |
| 00:38.48 | CosmicPenguin | I believe you'll want to stay with the same minor version for the kernel headers |
| 00:39.03 | CosmicPenguin | running a 2.4 on your target, use 2.4 headers. Running a 2.6 kernel, use 2.6 headers |
| 00:39.13 | CosmicPenguin | it probably doesn't matter that much, but you never know |
| 00:40.40 | pierrelux | ok |

| 18:23.02 | gcl | buildroot+uclibc question: how can I get buildroot to build uClibc w/ debug symbols? |
| 18:23.13 | gcl | I can't find anything in the documentation, or on the ML |
| 18:24.54 | sjhill | *sigh* |
| 18:24.56 | sjhill | kids these days |
| 18:25.04 | sjhill | bring up the config menu |
| 18:25.10 | sjhill | go to 'Toolchain Options' |
| 18:25.19 | sjhill | go clear down to the bottom |
| 18:25.26 | sjhill | select 'Target Optimizations' |
| 18:25.35 | sjhill | add in '-g' |
| 18:25.40 | sjhill | save your config and build |
| 18:25.46 | gcl | i did that. :p |
| 18:26.23 | gcl | libraries still don't seem to have debug symbols in them |
| 18:28.49 | CosmicPenguin | you have to rebulid any libraries you previously built |
| 18:29.41 | gcl | yup; did that |
| 18:30.36 | gcl | (doing it again now; just to make sure) |
| 18:36.10 | gcl | confirmed; 'file' reports the library as stripped, and readelf --debug-dump returns nothing |
| 18:36.39 | CosmicPenguin | ah - you asked the wrong question |
| 18:36.52 | gcl | :) what question should I ask? |
| 18:37.25 | CosmicPenguin | you asked how to build uclibc with debug symbols |
| 18:37.39 | CosmicPenguin | you should have asked how to keep the debug symbols in the library |
| 18:38.30 | gcl | or I'd be happy to know where to get the symbols so I can stuff them into GDB |
| 18:38.37 | gcl | :) |

| 19:53.56 | MonMotha | are you using one of the existing frameworks (like HID) or did you write your own driver? |

| 19:54.48 | prpplague | MonMotha: gadget drivers for usb slave devices |
| 19:54.53 | MonMotha | the driver I wrote was pretty independant. The device didn't really fit well under any existing category (it could possibly be considered HID, but not anything that Linxu already has support for) |
| 19:55.02 | MonMotha | prpplague: yeah, I know what it does, just don't know any of the internals |
| 19:55.09 | prpplague | MonMotha: ahh ok |
| 19:55.31 | MonMotha | I know if you set your own stuff up, you can specify how much data to move at once, and I think you may be able to override what the USB descriptor says |
