Sincecf75d7da98we have a build failures when building libgbm.so when valgrind package is selected because --static is always passed to pkg-config even for shared build. Even if -Dvalgrind=false on meson command line to build mesa, the valgrind libraries come from pkg-config libdrm... output/host/bin/pkg-config libdrm --libs --static -L[...]/sysroot/usr/lib -ldrm -lm -L[...]/sysroot/usr/lib/valgrind -lcoregrind-arm64-linux -lvex-arm64-linux -lgcc ... and break the build. See initial discussions: http://lists.busybox.net/pipermail/buildroot/2020-June/284543.html This is due to a wrong condition test added by the patch 0004-mesonbuild-dependencies-base.py-add-pkg_config_stati.patch. Indeed, pkg_config_static is a string, not a boolean; it is set to either 'true' or 'aflse' by our meson package infra. Since the returned object is a string, do not pass a boolean, but pas None (we only want to test against the 'true' string, so we don't care what we get back when it is not set, which never happens in Buildroot). Before this patch, the issue can be reproduced using the following defconfig: BR2_aarch64=y BR2_TOOLCHAIN_EXTERNAL=y BR2_PACKAGE_VALGRIND=y BR2_PACKAGE_MESA3D=y BR2_PACKAGE_MESA3D_DRI_DRIVER_SWRAST=y Fixes: http://autobuild.buildroot.net/results/1b5/1b58d73ecbbe1af2c3e140563d696cf32d1c4a5a/build-end.log Signed-off-by: Romain Naour <romain.naour@gmail.com> Cc: James Hilliard <james.hilliard1@gmail.com> Cc: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Cc: Fabrice Fontaine <fontaine.fabrice@gmail.com> [yann.morin.1998@free.fr: slightly reword the commit log] 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.
