| # 05:50:24 | huhlig-home | is crosstool-ng supposed to attempt to create executables when building a crosscompiler? |

| # 06:20:23 | huhlig-home | hello y_morin |
| # 06:27:12 | huhlig-home | hey y_morin is crosstool-ng supposed to attempt to build an executable when doing bare metal cross compile |
| # 06:31:58 | y_morin | huhlig-home: hey. As-is: no. A bare-metal compiler can generate executable code to directly run on the processor, ie. raw binary code, not ELF. |
| # 06:32:21 | y_morin | huhlig-home: What is it you are targetting? |
| # 06:32:36 | huhlig-home | armeb-32 |
| # 06:32:41 | huhlig-home | eabi |
| # 06:32:58 | huhlig-home | hopefully arm11 |
| # 06:33:36 | y_morin | huhlig-home: and what do you want to run on this? |
| # 06:36:21 | huhlig-home | I want to build a kernel |
| # 06:36:35 | huhlig-home | take a bit of assembler |
| # 06:36:46 | huhlig-home | create an object file with gdc |
| # 06:36:58 | huhlig-home | and then link them into a bare metal kernel |
| # 06:37:43 | y_morin | huhlig-home: what kernel? The Linux kernel? |
| # 06:37:43 | sh4rm4 | quits : Ping timeout: 252 seconds |
| # 06:38:27 | huhlig-home | no a custom kernel |
| # 06:39:27 | diorcety | quits : Quit: Leaving. |
| # 06:40:11 | y_morin | huhlig-home: Hmm... I don't know. Probably a bare-metal compiler would be enough. However, a complete compiler (ie. targeting Linux) will work, and is probably easier to setup. |
| # 06:41:15 | y_morin | huhlig-home: Because, a bare-metal compiler is just that: a _bare-metal_ compiler; you have to provide yourself all the basic low-level routines for your platform. |
| # 06:41:20 | huhlig-home | I know |
| # 06:41:24 | huhlig-home | I am fully aware of that |
| # 06:41:34 | y_morin | huhlig-home: hence the reason why gcc may be complaining about missing crti.o or some such. |
| # 06:41:35 | huhlig-home | I will need to do so anyway as DRuntime hasnt been ported to arm yet |
| # 06:42:34 | y_morin | huhlig-home: Oh, then you are mostly on your own there... I would suggest that you first get a compiler to work and make your kernel work as-is. Then, and only *then* add your D module. |
| # 06:43:08 | y_morin | huhlig-home: bare-metal is so specific to each platform. |
| # 06:44:18 | y_morin | huhlig-home: Also, do you use newlib in your bare-metal compiler, or no C library at all? |
| # 06:45:09 | huhlig-home | no c library preferable |
| # 06:45:11 | mnt_real | quits : Quit: Leaving |
| # 06:45:16 | huhlig-home | although newlib can run baremetal |
| # 06:45:30 | huhlig-home | on armeb |
| # 06:46:33 | y_morin | huhlig-home: I've almost never used newlib, but it provides some rather low-level stuff that can be usefull instead of rewriting it. |
| # 06:46:42 | y_morin | huhlig-home: newlib *is* for bare-metal. |
| # 06:46:54 | huhlig-home | yeah |
| # 06:46:55 | y_morin | (or Cygwin, if that matters) |
| # 06:47:07 | huhlig-home | I am trying to write a basic OS Kernel with only D |
| # 06:47:49 | y_morin | huhlig-home: Then, you're really on your own, sorry. :-/ |
| # 06:49:46 | sh4rm4 | joins #crosstool-ng |
| # 06:49:53 | huhlig-home | heh |
| # 06:50:01 | huhlig-home | sigh |
| # 06:54:40 | y_morin | huhlig-home: These days, people doing bare-metal are not legion anymore. And D has not really caught up (it's not even mainline in gcc). |
| # 06:55:02 | y_morin | As I see it, D is mostly academic. |
| # 06:55:25 | y_morin | (which does not mean it is a bad language, or a good one either) |
| # 06:56:24 | y_morin | Just D appeared too late, when C and C++ were already prevalent. |
| # 07:10:24 | huhlig-home | perhaps |
| # 07:10:33 | huhlig-home | but it works alot better and is far more safe |
| # 07:11:10 | huhlig-home | I think it has a place |
| # 07:11:18 | huhlig-home | its getting alot more popular too |

| # 13:30:44 | sabre_sd | hey guys, does anybody know what the latest stable version of eglibc is? |
| # 13:34:14 | y_morin | sabre_sd: eglibc does not do stable version. The latest branch is 2_17. |
| # 13:36:54 | sabre_sd | ah, sorry, i said it wrong. Im using the sample arm config, with some trivial modifications (dont use java, fortan) and instead glibc -> eglibc. And the build fails. with using glibc it runs fine. So somewhere in versions there has to be a problem?! |
