| # 16:54:19 | JWWJ | Hello all -- I built my own sample file by copying arm-unknown-linux-gnueabi to arm-xscale-linux-gnueabi and made modification. Wehn I do a ct-ng menuconfig, the values are correct, but when i do a ct-ng build, it creates armeb-unknown-linux-gnueabi files. any idea what I'm missing? |

| # 17:22:51 | bret | muep sh4rm4 I am trying to build gcc4.6+ with gfortran and no java support on Centos 5.9. I don't know if I need cloog/ppl. I thought it was a requirement to build gcc. |

| # 18:43:22 | sh4rm4 | bret, if you dont know what it is you dont need it |
| # 18:44:47 | bret | sh4rm4: I don't see a way to disable it |
| # 18:44:58 | sh4rm4 | iirc it's some optimization framework for scientific calculations which are unlikely to be encountered in any real world code |
| # 18:45:10 | bret | It looked pretty abstract |
| # 18:45:25 | Thomas1 | joins #crosstool-ng |
| # 18:45:30 | sh4rm4 | i've built entire linux distros without it |
| # 18:45:48 | bret | sh4rm4: do you know how to disable it? |
| # 18:45:55 | bret | i though GCC won't build without it? |
| # 18:46:50 | bret | I was looking for a way to build a tool chain independent from my OS, since some software that needs building requires a newer version of gfortran, higher than the system repository has |
| # 18:46:58 | sh4rm4 | in my gcc recipes, i dont disable it explicitly |
| # 18:47:12 | sh4rm4 | oh, you need a fortran compiler ? |
| # 18:47:36 | bret | gfortran 4.6+ |
| # 18:47:43 | sh4rm4 | ah |
| # 18:47:48 | bret | I'm on 44 or something |
| # 18:47:49 | sh4rm4 | maybe that explicitly needs |
| # 18:47:51 | sh4rm4 | it |
| # 18:47:52 | bret | cant go any higher |
| # 18:48:12 | bret | Cloog/ppl seems awfully picky about something |
| # 18:48:30 | sh4rm4 | for C and C++, if you build gcc and cloog/ppl is not around it detects that its missing and proceeds without it |
| # 18:48:52 | JWWJ | joins #crosstool-ng |
| # 18:48:53 | bret | unfortunately, I need newer fortran :( |
| # 18:48:57 | bret | for scientific software |

| # 18:50:19 | sh4rm4 | Try using the option --without-cloog when you run configure. |
| # 18:51:55 | bret | I just started a build⦠maybe you can help me decipher the errors |
| # 18:52:09 | bret | but will try that next |
| # 18:54:49 | JWWJ | If I could go back to my original problem -- Where is it picking up arm-unknown-linux-gnueabi when I'm not setting that for my sample? |
| # 19:00:56 | bret | No clue, I get the impression many of these folks are in a different time zone |
| # 19:16:30 | smartin | JWWJ: still your armeb-unknown-linux-gnueabi/arm-xscale-linux-gnueabi problem? |
| # 19:19:37 | smartin | bret: when trying to build os-independent toolchain, i usually build a static toolchain (marked as experimental) |
| # 19:19:47 | bret | ahh |
| # 19:19:48 | bret | ok |
| # 19:19:59 | bret | well, lets see how this one fails |
| # 19:20:06 | bret | I'll try that next |
| # 19:20:17 | bret | i have been beating my head against this for a few days now |
| # 19:35:35 | bret | smartin: sh4rm4 here is the error I am getting: http://pastebin.com/m4KrcX4J |
| # 19:35:52 | bret | il try the static opetion |
| # 19:35:56 | bret | option* wow |

| # 20:38:58 | bret | but still no go |
| # 20:52:18 | sh4rm4 | bret: do you manage to build the gfortran compiler without ct-ng being involved ? |
| # 20:52:26 | sh4rm4 | i.e. natively |
| # 20:53:29 | bret | I was working towards that but kept running into all of these dependency requirements |
| # 20:53:36 | bret | so I asked if there was a tool to help with that |
| # 20:53:39 | bret | which led me to here |

| # 21:05:17 | sh4rm4 | usually you need only gmp, mpfr and mpc as prereqs |
| # 21:05:36 | sh4rm4 | they're quite quick to build |
| # 21:05:58 | sh4rm4 | alternatively you can extract them into the gcc source tree and they will be picked up from there |
| # 21:10:01 | sh4rm4 | /www.multiprecision.org/mpc/download/mpc-0.9.tar.gz |
| # 21:10:09 | sh4rm4 | http://ftp.gnu.org/gnu/mpfr/mpfr-3.0.1.tar.bz2 |
| # 21:10:14 | sh4rm4 | http://ftpmirror.gnu.org/gmp/gmp-5.0.2.tar.bz2 |
| # 21:10:36 | sh4rm4 | those 3 versions are known to work on all gcc's from 4.4 - 4.7 |
| # 21:10:47 | sh4rm4 | at least they do in my setups |
| # 21:12:39 | sh4rm4 | these are the configure flags i usually use: |
| # 21:12:42 | sh4rm4 | --disable-multilib --disable-nls --disable-mudflap \ |
| # 21:12:42 | sh4rm4 | --disable-libmudflap --disable-libssp --disable-libgomp \ |
| # 21:12:42 | sh4rm4 | --disable-debug --disable-bootstrap \ |
| # 21:12:42 | sh4rm4 | --enable-lto --with-system-zlib \ |
| # 21:12:42 | sh4rm4 | --with-target-libiberty=no --with-target-zlib=no \ |
| # 21:12:43 | sh4rm4 | --enable-languages=c,c++ --enable-clocale=generic \ |
| # 21:13:05 | sh4rm4 | oh, enable-lto requires libelf, so remove that |
| # 21:13:24 | sh4rm4 | and --with-system-zlib depends on a custom deps |
| # 21:13:31 | sh4rm4 | s/deps/patch |
| # 21:14:04 | sh4rm4 | the more you disable, the less can go wrong |
