| # 05:18:13 | Norm | admittedly this is a super lame question, but iâve got crosstool working, am trying to compile something for an embedded ARM system |
| # 05:18:17 | Norm | but am not sure what sample i should use |
| # 05:18:29 | Norm | uname -a shows â2.6.36 #1 SMP PREEMPT Tue Feb 2 00:23:15 PST 2016 armv7l GNU/Linuxâ |
| # 05:18:36 | Norm | so i tried armv7-rpi2-linux-gnueabihf |
| # 05:18:50 | Norm | but even a simple âhello worldâ program yields âIllegal instruction (core dumped)" |
| # 05:18:54 | Norm | not sure where iâm going wrong :) |
| # 05:19:56 | bhundven | Norm: doesn't seem too lame, but lacking info |
| # 05:20:13 | bhundven | you are building ON an arm system or for an arm system? |
| # 05:20:17 | Norm | no, x86 for arm |
| # 05:20:30 | bhundven | the uname tripped me up |
| # 05:20:40 | Norm | oh sorry, uname was from the target system |
| # 05:20:53 | bhundven | so instead: cat /proc/cpuinfo |
| # 05:20:53 | Norm | compiling on 2.6.32-573.18.1.el6.x86_64 #1 SMP Wed Jan 6 11:20:49 EST 2016 x86_64 x86_64 x86_64 GNU/Linux |
| # 05:21:02 | Norm | (so x86_64) |
| # 05:21:07 | bhundven | on the arm system |
| # 05:21:10 | Norm | ok... |
| # 05:21:41 | Norm | https://gist.github.com/anonymous/ea35fbd58de51b8514d0 |
| # 05:21:43 | bhundven | oh, v7l |
| # 05:23:03 | bhundven | I'm guessing it's the hardfloat |
| # 05:23:16 | bhundven | try building arm-unknown-linux-gnueabi |
| # 05:23:29 | bhundven | but in arch use: armv7 |
| # 05:23:58 | bhundven | CT_ARCH_CPU |
| # 05:24:02 | Norm | i feel myself on the verge of a wiki-spiral (hours reading wikipedia) :) |
| # 05:24:13 | Norm | let me give that a shot, just a sec... |
| # 05:24:26 | bhundven | ok so to take a step back |
| # 05:24:46 | bhundven | is the target arm board a raspberry pi 2? |
| # 05:24:58 | Norm | no |
| # 05:25:00 | bhundven | ok |
| # 05:25:14 | Norm | one problem is i donât know that much about the target board, itâs a wireless access point |
| # 05:25:17 | bhundven | then you don't want: armv7-rpi2-linux-gnueabihf |
| # 05:25:28 | Norm | oh haha rpi2 == raspberri pi |
| # 05:25:32 | bhundven | ;) |
| # 05:25:32 | Norm | definitely didnât catch that |
| # 05:25:45 | bhundven | what is the target WAP? |
| # 05:26:27 | Norm | Aerohive AP130 |
| # 05:28:43 | bhundven | again, I'd just build: arm-unknown-linux-gnueabi and set CT_ARCH_CPU to armv7 |
| # 05:29:15 | Norm | iâll give it a shot |
| # 05:29:21 | Norm | this is definitely a new crazy world :) |
| # 05:29:27 | bhundven | not setting CT_ARCH_CPU would make a generic toolchain, which should still execute on the target |
| # 05:29:30 | Norm | thanks for the help! |
| # 05:29:44 | bhundven | it just won't be optimized for armv7 |
| # 05:30:38 | bhundven | Norm: also, if you need help an no one is answering, stick around. I'm about to go sleep. So I'll be out for the night, but you can also hit the mailing list if you need help. |
| # 05:31:01 | Norm | okay just to be clear (googling now), i just export CT_ARCH_CPU=armv7 before building? |
| # 05:31:24 | bhundven | no, in the directory you're building the toolchain, there should be a .config file |
| # 05:31:35 | bhundven | either edit it, or run ct-ng menuconfig |
| # 05:31:56 | Norm | yeah menuconfig doesnât give me armv7 as an option, only arm |
| # 05:32:00 | Norm | iâll do the .config file |
| # 05:32:19 | bhundven | on menuconfig you should find that Target Options -> Emit assembly for CPU |
| # 05:32:34 | Norm | okay iâll check it out, thanks again for the help! |
| # 05:32:55 | bhundven | https://gcc.gnu.org/onlinedocs/gcc-5.3.0/gcc/ARM-Options.html#ARM-Options |
| # 05:33:00 | bhundven | is also helpful |
| # 05:33:07 | Norm | got it |
| # 05:34:36 | bhundven | (see -mtune -march -mcpu |
| # 05:35:07 | bhundven | CT_ARCH_TUNE, CT_ARCH_ARCH, and CT_ARCH_CPU match the above options) |
| # 05:37:30 | Norm | mmm, anger⦠|
| # 05:37:36 | Norm | lib/crosstool-ng-1.22.0/scripts/build/arch/armv7.sh: No such file or directory |
| # 05:37:39 | Norm | iâll stick with âarmâ for now |
