In commit0e2be4db8a("package/pkg-generic: make file list logic parallel build compatible"), the logic to create the list of files installed by a particular package was significantly reworked to be compatible with top-level parallel build. Before this commit, there was only a after-install step of listing the files in HOST_DIR/TARGET_DIR/STAGING_DIR. But after this commit, we now have a before-install logic and an after-install logic. It turns out that when the before-install logic is called for the very first host package, $(HOST_DIR) doesn't exist yet, and therefore the cd $(2) fails, with an error message: /bin/sh: line 0: cd: /home/thomas/buildroot/output/host: No such file or directory In fact, $(HOST_DIR), $(STAGING_DIR), $(TARGET_DIR) and $(BINARIES_DIR) are created by the make rules for host installation, staging installation, target installation and images installation, but *after* calling the step_start hooks. So, we simply fix this problem by creating the directories *before* calling the step_start hooks. 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 Freenode IRC.
