On autobuilder config with BR2_TOOLCHAIN_HAS_THREADS not set the following error happens when building the pthreadpool package: ``` -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - not found -- Check if compiler accepts -pthread -- Check if compiler accepts -pthread - no CMake Error at /home/buildroot/instance-0/output-1/host/share/cmake-3.31/Modules/FindPackageHandleStandardArgs.cmake:233 (message): Could NOT find Threads (missing: Threads_FOUND) Call Stack (most recent call first): /home/buildroot/instance-0/output-1/host/share/cmake-3.31/Modules/FindPackageHandleStandardArgs.cmake:603 (_FPHSA_FAILURE_MESSAGE) /home/buildroot/instance-0/output-1/host/share/cmake-3.31/Modules/FindThreads.cmake:226 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) CMakeLists.txt:143 (FIND_PACKAGE) -- Configuring incomplete, errors occurred! ``` This can be reproduced with: ``` cat >.config <<EOF BR2_armeb=y BR2_TOOLCHAIN_BUILDROOT_UCLIBC=y BR2_PTHREADS_NONE=y BR2_PACKAGE_PTHREADPOOL=y EOF make olddefconfig make pthreadpool ``` Since the introduction of this package in [1], the dependency was not included. Since this package was part of the tensorflow-lite dependencies that required thread it was not an issue. This patch adds BR2_TOOLCHAIN_HAS_THREADS in the dependency to avoid errors when built as a standalone package.

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 OFTC IRC.
