Hi,
I'm trying to cross-compile gentoo for armv4 , board Mini2440.
I get the following error when emerging dev-libs/mpfr-2.4.1_p5:

I got this problem for other packages too.
I thought that LDFLAGS would be enough.
If someone has any clues, is there an other variable that can be used?
Thanks.
Maxime.

you should verify (using "file") that it's armv4
but ... the "OE bitbake" (gnu linux builder for embedded) is using qemu in oder to crosscompile
host -> qemu.virtualmachine -> arm native compiling
i hardly suggest you it ! |

Hi,
I check it out, and of course it's not armv4 because it's a lib from the host system which is i686.
What i don't understand is why it uses this one (which is of for the host system) instead of the cross compiled one located in my ${ROOT}/usr/lib ( I checked, it exist !)
I'm currently trying to make it work in qemu, but the mini2440 board is not supported in the main branch of qemu.
It could have been great to use emerge to cross compile without having to emulate the hole system.
Thanks for your response anyway.

| Does it help if you add "--sysroot=${ROOT}/usr/lib" to CFLAGS/CXXFLAGS? |

It works very well for me on MIPS and SH4, maybe other
cflags clash with it. What does config.log say about the error? |

Do you have a complete libc in your ARM root? Copy the .o and .a files
from /usr/armv4tl-softfloat-linux-gnueabi/usr/lib/*.{ao} to your ${ROOT}/usr/lib.
The idea behind sysroot is that you point gcc/ld to the root of a _complete_
environment (something you'd use as a NFSroot for example). |

sorry, but ... could you just use qemu/armv4/armv5 (with the right endianess) machine ?
you don't need any "mini2440 board support", you just need a proper arm-kernel (NPTL? > 2.6.18!) |

roarinelk:
Your right I use now ROOT=/usr/${CHOST} and --sysroot=${ROOT} in CFLAGS and it work.
I thought I could just use cross emerge to build a rootfs in another directory.
basic lib should have been missing in my previous root dir.
I will investigate later.
Thanks

I got an error :
| Code: | | qemu: fatal: Trying to execute code outside RAM or ROM at 0x00001000 |
Which may be not related to the version used.
I found a fork of qemu whit specific -M mini2440, I haven't still understand whats the difference with a versatileab or versatilepb.
It does not solve this error.
Anyway I still have some info to found on the web before asking on the forum. |
