Package: gcc-6-arm-linux-gnueabihf Version: 6.1.1-9cross1 Severity: important
Dear Maintainer, If I cross-compile any code (even a basic hello-world) and then attempt to link the resulting objects on the target system (stretch, armhf) using the native gcc-6 toolchain (which is 6.2.0 in testing and has already been for a while) I get the following failure: /usr/bin/ld: hello.o: relocation R_ARM_THM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC hello.o: error adding symbols: Bad value collect2: error: ld returned 1 exit status Recompiling with -fPIC as suggested does in fact fix the problem, but this should not be necessary and never has been. (Compiling without it but linking with the cross-toolchain also results in a working binary.) Note that cross-compiling + native linking is for example needed to be able to use distcc to speed up compilation on small ARM systems by delegating most of the work to a build server, which is how I ran into this issue. This setup is currently completely broken due to this bug. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (100, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.8.0-2.1-liquorix-amd64 (SMP w/4 CPU cores; PREEMPT) Locale: LANG=en_NL.UTF-8, LC_CTYPE=en_NL.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages gcc-6-arm-linux-gnueabihf depends on: ii binutils-arm-linux-gnueabihf 2.27.51.20161108-1 ii cpp-6-arm-linux-gnueabihf 6.1.1-9cross1 ii gcc-6-arm-linux-gnueabihf-base 6.1.1-9cross1 ii libc6 2.24-5 ii libcc1-0 6.2.0-13 ii libgcc-6-dev-armhf-cross 6.1.1-9cross1 ii libgcc1 1:6.2.0-13 ii libgmp10 2:6.1.1+dfsg-1 ii libisl15 0.17.1-1 ii libmpc3 1.0.3-1 ii libmpfr4 3.1.5-1 ii libstdc++6 6.2.0-13 ii zlib1g 1:1.2.8.dfsg-2+b3 Versions of packages gcc-6-arm-linux-gnueabihf recommends: ii libc6-dev-armhf-cross 2.24-1cross1 Versions of packages gcc-6-arm-linux-gnueabihf suggests: ii gcc-6-doc 6.1.0-1 pn gcc-6-locales <none> pn libasan3-dbg-armhf-cross <none> pn libatomic1-dbg-armhf-cross <none> pn libcilkrts5-dbg-armhf-cross <none> pn libgcc1-dbg-armhf-cross <none> pn libgomp1-dbg-armhf-cross <none> pn libitm1-dbg-armhf-cross <none> pn liblsan0-dbg-armhf-cross <none> pn libmpx2-dbg-armhf-cross <none> pn libquadmath0-dbg-armhf-cross <none> pn libtsan0-dbg-armhf-cross <none> pn libubsan0-dbg-armhf-cross <none> -- no debconf information
