Commit0e2ee0e6e8(package.snappy: fix static builds with threads) added LIBS=-pthread to configure options to fix static build with threads on some architectures. This works for autotools packages. Then, commitd26282b3aa(package/snappy: bump version, switch to cmake) switched to cmake that does not understand the 'LIBS' parameter. As pointed out by Thomas[1] the special handling of libpthread for static builds is not needed anymore: it was needed only to build the tests, and these are no longer built. Note that packages that link statically with snappy will still need to link with -pthread. Only two in-tree packages currently depend on snappy: lua-csnappy depends on !BR2_STATIC_LIBS and leveldb adds -pthread from its build system. Tested with the following musl & uclibc defconfigs which also fix build errors: http://autobuild.buildroot.net/results/39f/39f9fc4300ddca19e8a533765b46838003752000/ http://autobuild.buildroot.net/results/886/8860b9259f7a3aecb2ddbfa787be048072bd347b/ [1] http://lists.busybox.net/pipermail/buildroot/2017-July/199549.html Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de> Acked-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.
