Since version 4.5, squashfs-tools provides two additional utilities: sqfstar and sqfscat. But their functionality is bundled within mksquashfs and unsquashfs respectively, so that sqfstar is a symlink to sqfstar, and sqfscat a symlink to unsquashfs. Unfortunately, due to how the symlinks were created, they had a bogus target when INSTALL_DIR was not empty, leading to things like this: ./usr/bin/sqfscat -> /home/peko/autobuild/instance-1/output-2/target/usr/bin/unsquashfs ./usr/bin/sqfstar -> /home/peko/autobuild/instance-1/output-2/target/usr/bin/mksquashfs Not only they are wrong, but they also cause reproducible build issues (this is how they were detected). This commit backports an upstream patch that fixes this problem. This is also fixing the squashfs-tools part of the reproducible build issues at: http://autobuild.buildroot.net/results/00af5dca8c30b243af1e8cde3b02e264f7603442/diffoscope-results.txt Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
