@NiLuJe : Do you like writing build systems in Make language?
I could clone YEM's development repository into my public repo system, then you send me a pub-key and we can both work on extending the unfinished parts of ct-ng. Last edited by knc1; 09-04-2012 at 09:30 AM. |

@knc1: I wouldn't say 'like' exactly, but I can somewhat make sense of it, sometimes... ;D.
What do you have in mind? Since I'm doing all of this for 'fun', I'm more likely to be of use if there's something that I actually have an interest in . |

If I can get something out that twobob can use, I will not be making any changes at all to ct-ng. |

https://launchpad.net/linaro-toolcha...estone/2012.08 Then see if I can just "tweak" it for the older glibc. Either this plan will "just work" and I will be done today . . . OR I may not live long enough to get it working at all. |

@knc1: Huh, I wasn't aware of Linaro's ct-ng branch... (FWIW, I'm using upstream's ct-ng, it supports Linaro's GCC/GDB fine ).
Their sample softfp config is very similar to what I do for my K3/K5 TC, except I don't rely on their prebuilt lib/kernel, and I don't default to thumb mode (in fact, I've never used it, going by the assumption that thumb1 wasn't worth it... I might have to look into it for the K5, which supports thumb2...) . Last edited by NiLuJe; 09-04-2012 at 11:13 AM. |

I have ct-ng_1.16.0 installed and I see that they used 1.13.1 (the same one Buildroot is stuck on). I may or may not try moving the 1.13 config to 1.16 The other things you mention will go away in the "tweaking". At least that is the initial plan. Will see how long that plan holds up. |

The resouce section (appendix B) of the reference manual has not (yet) been updated. Now - take the sources that where used to build that release (K4&K5 style hardware) and cobble them into something suitable for the K3. In the set of things: Code:

This tool-chain can be re-built for an S390, but the question is, can it be re-built for an i.MX35? Hmm... Just need to dig around a bit to find a suitably old enough glibc set of sources. |

The ct-ng patches directory is cumlative. It goes back to glibc-2.5 and gcc-4.3 The "oldest" that can be built / can build itself (gcc-4.2 is reported to be "too old" to build glibc these days). Now, see how I do on the ct-ng learning curves. See if I can stay on the road course and not do a towbob (bump across the in-field). Here is some of the curves in the course: https://bugs.launchpad.net/linaro-toolchain-binaries #1034186 is going to bite us - we have VFP, but no Thumb-2 on the i.MX35 - so don't expect gdb-server to work.
