 Posted: Mon Dec 31, 2012 2:41 pm Post subject: gcc inside qemu chroot (mipsel-softfloat-linux-gnu) |
 |
|
hi there,
i've built a basic rootfs (mipsel-softfloat-linux-gnu) which is used for my tests with qemu-user (chroot). i'm able to chroot but binaries built within this environment refuse to run. look at this:
| Code: |
skynet mipsel-softfloat-linux-gnu # chroot .
skynet / # ls
bin dev etc lib packages proc root run sbin sys sys-include tmp usr var
skynet / # cd root/
skynet ~ # gcc -v test.c -o test
Using built-in specs.

| can you dig a bit why 'test' is apparently an invalid binary? What libraries does it pull in, what format is it? |
