| 15:59.43 | lanouettea | Hello, I would appreciate some help to add a simple, 1-file, shared C library to my buildroot compilation. |
| 16:00.46 | kos_tom | you want to add a C library ? |
| 16:00.51 | kos_tom | or an application that uses the C library |
| 16:00.54 | kos_tom | <PROTECTED> |
| 16:01.34 | lanouettea | I made a shared library in C. I would like it to be compiled and included when running my buildroot compilation |
| 16:02.09 | kos_tom | well, do you have a Makefile, or autotools-based, or CMake-based build system for your library ? |
| 16:03.03 | lanouettea | I will make a Makefile, but was wondering if I should include any special rules in it |
| 16:04.03 | kos_tom | if it's a Makefile, then you'll use the GENTARGETS infrastructure of Buildroot to integrate your library as a package |
| 16:04.18 | kos_tom | and with this infrastructure, you can configure/build/install your component as you wish. |
| 16:04.31 | kos_tom | so you can write your Makefile however you want |

| 16:06.09 | lanouettea | Ok. One things puzzles me about adding custom packages to Buildroot. After reading the documentation, I was under the impression I'm forced to put my package sources in a tarball? |
| 16:08.11 | jow_laptop | you probably just have to override the default fetch source target which is tailored for .tar.gz download and unpack which applies to 99% of the packages |
| 16:09.12 | kos_tom | lanouettea: originally, yes. |
| 16:09.21 | kos_tom | you have several options these days, though |
| 16:09.43 | kos_tom | <PROTECTED> |
| 16:10.09 | kos_tom | <PROTECTED> |
| 16:12.26 | lanouettea | Thanks! I'm forced to use a buildroot version bundled with an SDK. I believe it's a buildroot version from 2008_06_20. I don't believe this includes the SITE_METHOD and _SITE parameters, so I'll go with the second method |
| 16:16.57 | lanouettea | Thanks a lot for your help. I will try this out and let you know if I get any issues I can't resolve by myself :) |

| 20:18.10 | khem | last time when I was chasing it. seemed something in obstack |
| 20:18.15 | khem | but not conclusive |
| 20:18.23 | kos_tom | khem: if gas or ld are buggy and create memory corruption, then rebooting will not improve the situation. |
| 20:18.44 | khem | kos_tom: it does since its dynamic memory allocation |
| 20:20.09 | kos_tom | khem: well, restarting gas or ld is the same as rebooting, no ? |
| 20:20.22 | kos_tom | khem: or do you mean it triggers some sort of kernel-side corruption ? |
| 20:20.57 | khem | kos_tom: no idea what happens but reboot helps, I guess its related to memory chunks that get allocated |
| 20:21.14 | kos_tom | waouh, sounds nasty. |
| 20:21.15 | khem | kind of voodoo for me |
| 20:21.24 | kos_tom | is there some bug reported somewhere associated to this ? |
