For some odd reason, the new pkg-config 1.5.3 changed the behavior of "pkg-config --version": as soon as another argument than "--version" is passed, the code assumes the user wanted to run "--modversion" instead. Sadly, this breaks badly with our pkg-config wrapper that unconditionally passes --static to pkg-config when BR2_STATIC_LIBS=y. When ffmpeg calls "pkg-config --version" to test if pkg-config is available and functional, it's actually "pkg-config --static --version" that gets executed. pkg-config assumes that the user wanted to use --modversion and bails out with an error. This causes a build failure of ffmpeg in BR2_STATIC_LIBS=y configuration. This misbehavior of pkg-config has been reported upstream at https://git.dereferenced.org/pkgconf/pkgconf/issues/19, but until it gets fixed, we work around the issue by reverting the commit that does the "hey let's assume you're using --modversion if --version is passed with more than one argument". Fixes: http://autobuild.buildroot.net/results/ed82a95e1866ea2caadbb3433b2a255b2cf621d2/ (and plenty of other ffmpeg + BR2_STATIC_LIBS=y build failures) Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Reviewed-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.
