Building this defconfig BR2_x86_64=y BR2_TOOLCHAIN_EXTERNAL=y BR2_PACKAGE_NEON=y BR2_PACKAGE_NEON_ZLIB=y does not build libneon with zlib support, quoting configure log: configure: zlib not enabled although the configure parameter --with-zlib=/home/bernd/buildroot/output/host/x86_64-buildroot-linux-gnu/sysroot was used. The reason is the addition of "=$(STAGING_DIR)" to --with-zlib which was added to buildroot in 2008 with commitcc6562ff83. The upstream code, which expects only "yes", all other values lead to the else-condition, is unchanged since 2004: https://github.com/notroj/neon/blame/0.37.1/macros/neon.m4#L478 so a backport of this patch to LTS branches should be considered. With this patch the configure log shows: checking for zlib.h... yes checking for inflate in -lz... yes configure: zlib support enabled, using -lz Signed-off-by: Bernd Kuhls <bernd@kuhls.net> Signed-off-by: Julien Olivain <ju.o@free.fr> (cherry picked from commit5e917c3a81) Signed-off-by: Thomas Perale <thomas.perale@mind.be>
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 https://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.
