Package: gcc-arm-linux-gnueabi Version: 4:8.3.0-1 When I compile a program with
`arm-linux-gnueabi-gcc --sysroot /path/to/sysroot foo.c -o foo' , the output
`foo' linked to the glibc from libc6-armel-cross, rather than that in
`/path/to/sysroot' Steps to reproduce: 1. Prepare dummy.c: `int main() {return
0;}' 2. Prepare a armel sysroot with OLDER glibc version, like Debian jessie:
`mkdir /tmp/jessie && cdebootstrap-static -a armel --foreign --include
libc6-dev jessie /tmp/jessie http://archive.debian.org/debian' 3. Compile. Here
is a transcript: $ arm-linux-gnueabi-gcc --sysroot /tmp/jessie dummy.c -o dummy
$ file dummy dummy: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 3.2.0,
BuildID[sha1]=a6c587dc6a3faa87e2b128af7c1ed208d0a9807a, not stripped $ The
existance of `for GNU/Linux 3.2.0' is an evidence that `arm-linux-gnueabi-gcc'
linked the executable to the glibc from libc6-armel-cross. I suppose that the
`dummy' executable, should be linked to glibc in `/tmp/jessie'. A temporary
solution that works for me: Just remove `libc6-armel-cross' and
`libc6-dev-armel-cross', then `arm-linux-gnueabi-gcc' uses the glibc I
expected. Here is a transcript: $ sudo dpkg -r --force-depends
