rabbitmq-c currently fails to build in a number of static linking situations, due to two issues: - CMake FindOpenSSL module is buggy. Even though it uses pkg-config, it doesn't use the information returned by pkg-config, and therefore doesn't know about second order libraries that need be part of the link for static linking to succeed. Due to this, -lz is not passed, and therefore rabbitmq-c fails when linking against libssl/libcrypto. This issue has been reported to upstream CMake at https://gitlab.kitware.com/cmake/cmake/issues/16885. - popt might use libintl, but CMake doesn't know about that. For autotools based packages, we typically work around this by passing LIBS=, but CMake apparently has no equivalent to LIBS=. To workaround this, we only use the OpenSSL and Popt optional dependencies in dynamic linking situations.

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.
