The host shared libraries produced by CMake were missing a proper DT_RPATH. That became a problem because the DT_RPATH handling is not transitive by design. Consider the following scenario: - pkg-a provides a library (`liba`) which links to `libpcre` - pkg-b provides a binary (`foo`) and a shared library (`libb`) which is needed by that binary - `libb` links to `liba` - pkg-a and pkg-b are both built by CMake In this scenario, `foo` is correctly marked with DT_RPATH pointing to host/lib/, but that path is not used when (recursively) resolving PCRE's symbols in `liba`. When attempting to run the `foo` binary, the linker correctly finds both `liba` and `libb`, but it cannot find the libpcre.so as built by Buildroot for host.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
