| # 16:27:32 | orionk | joins #crosstool-ng |
| # 16:27:44 | orionk | can someoen tell me which arm compiler i need for my modem ? |
| # 16:28:34 | orionk | http://pastebin.com/ESEBQLLb |
| # 16:29:14 | orionk | i tried with arm-unknown-linux-gnueabi but a simple hello world in C gives seg fault |
| # 16:32:52 | orionk | doing a file on an executable i got from the modem i get |
| # 16:32:58 | orionk | ./root/fmac: ELF 32-bit LSB executable, ARM, version 1, dynamically linked (uses shared libs), stripped |
| # 16:44:45 | orionk | doing a readelf on the executable i got from modem i see this http://pastebin.com/wgaduEFH |

| # 16:48:28 | y_morin | diorcety: Hey! :-) |
| # 16:49:41 | y_morin | diorcety: I have been away for some time lately, due to holidays. |
| # 16:50:26 | y_morin | orionk: Your device is an armv5tej, so you have to configure crosstool-NG accordingly. See gcc's man page, and the various options in crosstool-NG menuconfig, in target sub-menu. |
| # 16:53:05 | diorcety | y_morin: i assumed that :) how was your holidays? |
| # 16:53:47 | orionk | y_morin: anything special i need to check on the target submenu ? |
| # 16:54:27 | y_morin | diorcety: Not too bad, considering we've been re-doing the kitchen from scratch, and it took almost all of our time, so I did not even have the time to power on my PC for ~3 weeks... |
| # 16:55:20 | y_morin | orionk: look at the various optimisation entries: "Architecture level", "Tune for CPU" and the likes |
| # 16:56:25 | orionk | thanks.... just for a test ... did a readelf on the hello world and this is what i got http://pastebin.com/0RTB3Wbr |
| # 16:57:18 | orionk | the OS/ABI is UNIX - System V but on the original executalble from the modem is OS/ABI: ARM |
| # 16:57:24 | diorcety | y_morin: ok. when you have time, can we take some time for talking about my patch (adding a cc) because we having a working clang env |
| # 16:58:04 | y_morin | diorcety: the one that was already sent to the list? |
| # 17:01:49 | y_morin | orionk: crosstool-Ng is not meant to target existing systems, but rather build new systems from scratch. |
| # 17:02:11 | y_morin | orionk: Otherwise, you'd have to get the exact same toolchain as was used for the rest of the system |
| # 17:02:29 | orionk | anyway i can figure it out from the existing executables ? |
| # 17:02:41 | y_morin | orionk: your modem uses "Version5 EABI" which, IIRC, is deprecated (I think), and is not supported by crosstool-NG anyway. |
| # 17:02:43 | orionk | all im trying ( for the moment ) is to run a simple hello world in C |
| # 17:03:01 | orionk | what are the alternatives since its deprecated ? |
| # 17:03:16 | y_morin | orionk: you *might* be able to do it if you do either static linking, or build a complete chroot. |
| # 17:03:59 | orionk | any link you might share ? |
| # 17:05:20 | sh4rm4 | quits : Remote host closed the connection |
| # 17:05:44 | diorcety | y_morin: yes |
| # 17:07:04 | diorcety | y_morin: the patch was sent in order to prepare to include another c compiler |
| # 17:07:30 | diorcety | y_morin: we have a working solution for llvm/clang (2.7,2.8,2.9,3.0,3.1) ... i 'am working on 3.2 and 3.3 |
| # 17:10:16 | djerome | quits : Remote host closed the connection |
| # 17:12:49 | y_morin | diorcety: We're speaking patch "cc/gcc: Split gcc configurations and functions from cc ones", right? This one /only/ separate config options, and would be followed by another patch that adds the new CC, right? |
| # 17:13:44 | diorcety | yes, if you agree. Add clang |
| # 17:16:56 | y_morin | diorcety: Well, the renaming I don't really care about, so probably good to go, yes. |
| # 17:17:19 | y_morin | diorcety: I'm just a bit worried about the clang stuff, though... |
| # 17:17:53 | y_morin | diorcety: crosstool-Ng was much centered around gcc from the beginning, and it shows limits at adding alternatives. |
| # 17:18:56 | y_morin | diorcety: Besides, I have less time these days to hack on crosstool-NG, because of other side projects that have sprung into life (no, not a baby!), and it sucks a lot of my time. |
| # 17:19:24 | y_morin | But I will try to recenter a bit more on ct-ng now... |
| # 17:19:45 | y_morin | Anyway, GTG now, back either in a minute, or much later tonight... |
| # 17:53:47 | diorcety | y_morin: there is no modification on ct-ng |
| # 17:54:00 | diorcety | only add llvm has library and clang as cc |
| # 17:54:03 | diorcety | nothing more |
