| 05:32.02 | swinchen | Hi all. When building a cross-compiler is it possible to build gfortran? |
| 05:33.34 | Mirell | swinchen: Cross-compiling Fortran..? |
| 05:35.36 | swinchen | aye, why know? I am doing some seriously math-intensive stuff and it would be great to be able to use a fortran module or two |
| 05:36.09 | swinchen | why know = why not |
| 05:37.29 | swinchen | EKF requires a ton of matrix math, and I am very familiar with Matlab.... fortran would be great choice. But if getting a gfortran cross-compiler is difficult/impossible I won't bother trying |
| 05:39.21 | Mirell | swinchen: I honestly have never tried. I just asked since it seemed to be odd. |
| 05:39.45 | Mirell | swinchen: I'm curious to see if it would compile natively, though... |
| 05:40.30 | swinchen | do you mean ARM -> ARM? or x86 -> x86? |
| 05:45.57 | Mirell | swinchen: Yah, ARM under QEMU/target board |
| 05:46.36 | Mirell | swinchen: I've been more focused on getting stuff just to natively compile, than cross-compile. Because generally the former can be submitted upstream |
| 05:46.58 | Mirell | swinchen: But as I said, even what I have to cross-compile, haven't honestly ever tried with Fortran. |
| 05:47.15 | Mirell | swinchen: That's just me admittedly. ^^ |
| 05:47.59 | swinchen | Hrmmm, that isn't a bad idea. If I can't cross compile I will have to look into QEMU and native compilation. hrmmm... not sure what "submitted upstream" means |
| 05:49.17 | Mirell | swinchen: Lot of cross-compile patches make hacks which will allow the package to work on whatever target, |
| 05:49.35 | Mirell | swinchen: But are ugly/broken enough to break it on the normal targets |
| 05:50.22 | Mirell | swinchen: Has a lot to do with making autoconf less *stupid* I've noticed, mainly. Sometimes just hard-coded crap, but mainly the former. |
| 05:51.50 | Mirell | But other people here may have more experience than I with Fortan-cross-compilationess... |
| 05:51.51 | swinchen | ahhh I see. Somehow I think my chances of getting a working cross compiler are slim :P I just realized I can't really compile it natively either... I don't want the libc, or ulibc version. |
| 05:52.04 | swinchen | Ok. Well thanks for the tidbits :) |
| 05:52.28 | Mirell | Sure. Sorry I couldn't help more... |
| 05:52.41 | Mirell | Fortran was a language I left in the early 90s, so. ^^ |
| 05:53.46 | swinchen | I am just picking it up. lucky me :) Well have a good night/day. I am off to bed. Thanks again. |
| 05:53.49 | Mirell | swinchen: Although not glibc and uclibc? |
| 05:53.58 | Mirell | swinchen: What else then? o.O |
| 05:54.04 | Mirell | swinchen: And 'night, otherwise. |
| 05:54.08 | swinchen | Nope. This is for a microcontroller. Not running linux |
| 05:54.12 | Mirell | Aha |
| 05:54.27 | Mirell | Well, I wish you the best of luck, since that's ultra-niche... |
| 05:54.34 | Mirell | But, 'night! |
| 05:54.44 | swinchen | heh night :) |
| 05:56.10 | Mirell | adds that to his "Rare Potential Use Cases" list... |
| 05:57.57 | Mirell | Also, I'm curious to see if anyone else has done that who's idling. >.< |
