# 11:03:10 Joker-2 Hello
# 11:03:28 Joker-2 I created toolchain with ct-ng. Now, how am I supposed to boot into that toolchain ?
# 11:03:48 Joker-2 so that I can compile extra packages by hand against this toolchain
# 11:09:36 tkil Joker-2 -- you don't "boot into" a toolchain. use use executables from that toolchain in the host environment to build executables which can run on the target.
# 11:10:19 Joker-2 tkil, If I used that toolchain in "buildroot" then can I use the resultant image to "boot into"
# 11:11:20 tkil well, you need either an emulator or the actual hardware. you build your image for the target, then transfer it to the target somehow, then cause your target to run it. if it's a kernel, then yes, a reboot is usually required.
# 11:11:56 tkil the other instructions here are out of date, but this section is the gist of it: http://buffalo.nas-central.org/wiki/Build_%28and_use%29_a_cross-toolchain_using_Dan_Kegel%27s_crosstool_0.38#Using_a_Cross-Toolchain
# 11:14:36 tkil Joker-2 -- although, depending on your target, you might have better luck with more integrated systems. you mentioned buildroot; the final output from that ought to be (at least) a kernel and a disk image. /me reads docs and it generates the bootloader as well... nice.
# 11:14:45 tkil wishes he had know all this stuff 4 years ago. :)
# 11:15:14 tkil Joker-2 -- what is your target? e.g., raspberry pi, router, something else?
# 11:15:39 Joker-2 tkil, Thin client
# 11:16:26 tkil like, chromebook type thing, or?
# 11:18:27 Joker-2 sort of. It is a board with less CPU and used FLASH for storage purpose
# 11:18:50 Joker-2 mostly used to connect to server like ICA, RDP
# 11:21:06 tkil ok. so you have buildroot configured for your cpu / gfx / storage / client progs? and you've successfully built everything?
# 11:23:59 Joker-2 yeah. I guess so.
# 11:24:34 Joker-2 Now I am trying to boot into it, but it fails somehow ( not giving me login OR shell prompt )
# 11:25:58 diorcety1 joins #crosstool-ng
# 11:27:16 tkil but you see kernel messages?
# 11:27:50 Joker-2 yeah....It started all daemons mentioned in /etc/rc5.d and then it get stuck
# 11:31:47 tkil so you even have init running. hm. how does buildroot handle /dev entries? might be that your virtual terminals aren't getting set up quite right.
# 11:32:03 Joker-2 what is the correct value for "Port to run a getty (login prompt)" in buildroot
# 11:32:09 Joker-2 I am running this image in vmware
# 11:32:13 tkil you might also try to find a buildroot channel / forum, as it seems that the actuall cross compiling is working correctly. :(
# 11:32:21 tkil (and it's 6:30a eastern USA time, so usa devs should be waking up soon.)
# 11:32:37 Joker-2 it's 5:02 pm here
# 11:42:16 tkil Joker-2 -- also: http://buildroot.uclibc.org/downloads/manual/manual.html#_frequently_asked_questions_amp_troubleshooting
# 13:18:17 Joker-2 tkil, THnx
# 13:18:35 Joker-2 Issue was the _wrong_ configuration

# 18:22:31 diorcety y_morin: i have investigate my issue
# 18:23:12 y_morin diorcety: Hmm. THe llvmgcc problem, right?
# 18:24:27 diorcety y_morin: it's not a llvmgcc issue
# 18:24:35 diorcety y_morin: it appears to be a gcc 4.2.1 issue
# 18:24:53 diorcety y_morin: i have tried to compile gcc 4.2.1 (obsolete) i have a same issue
# 18:25:12 y_morin diorcety: OK. Why such an old gcc version? Because llvm has not been ported to a GPLv3 gcc?
# 18:25:16 diorcety y_morin: i'm currently tring to build it with the 1.16 release and not my git
# 18:25:30 diorcety y_morin: llvmgcc is based on 4.2.1
# 18:25:41 y_morin diorcety: latest ct-ng is 1.17, not 1.16.
# 18:26:09 diorcety y_morin: let's see with 1.16 first :D
# 18:26:32 y_morin diorcety: Is that because gcc 4.2.1 is the latest to be GPLv2 that llvm has not been ported to a more recent gcc?
# 18:27:20 diorcety y_morin: llvmgcc is like obsolete ... but it can be usefull (even if you doesn't want integrate it)
# 18:27:33 y_morin diorcety: OK.
# 18:28:19 diorcety y_morin: i confirm. bare-metal build x86 with gcc 4.2.1 is not working ..
# 18:50:21 diorcety y_morin: Did I miss├é┬ásomething?
# 18:51:23 y_morin diorcety: I have not tried bare-metal x86 for a long time. Not sure it is supported... :-/
# 18:51:51 y_morin diorcety: You should try with a more recent gcc to see if it works. If it does, then it's a bug in gcc-4.2.1.
# 18:52:08 y_morin diorcety: If it still does not work, then maybe we're doing something incorrect in ct-ng...
# 18:52:18 diorcety ok
# 18:52:32 diorcety i am currently running tests ..
# 18:52:45 diorcety i will try with the last version (just before experimental)
# 18:53:31 y_morin diorcety: OK.
# 19:01:07 diorcety y_morin: 4.6.3 works
