Enable sysroot support
Last modified: 2014-06-17 09:29:03 EDT
Created attachment 802102 [details] spec patch Description of problem: I am aware that cross-{binutils,gcc} are limited to be useful only for bootloader/kernel compilation as there is no userspace support in packages. But they can also be used for userspace compilation when sysroot with libraries/headers is created. Version-Release number of selected component (if applicable): 4.8.1-5.1 How reproducible: always Steps to Reproduce: 1. grab aarch64 system image 2. populate it with glibc-devel 3. mount at /mnt 4. aarch64-linux-gnu-gcc helloworld.c --sysroot /mnt -o hello-aarch64 Actual results: "linker is not configured for sysroots" Expected results: links and gives proper binary Additional info: https://bugzilla.redhat.com/show_bug.cgi?id=1011412 was reported for cross-binutils.
+ --with-sysroot=/ \ This does not work correctly. It mixes stuff from /usr/include (specifically gnu/stubs.h) into the foreign libgccs. Also, this doesn't build on Fedora arm rawhide as this results in trying to access a non-existent file.
This should be dealt with in cross-gcc-4.8.2-2, which should be hitting updates-testing shortly. Note that the default sysroot is /usr/<arch>/sys-root/ rather than / as the latter causes problems when compiling libgcc.
