When enabling the openscap package and the libnss library _but not_ libgcrypt, the build can fail on the following error: ../src/libopenscap.so.33.1.3: undefined reference to `crapi_init' The issue is due to the fact that the corresponding Makefile systematically forces -DWITH_CRYPTO=gcrypt: openscap CMake instrumentation then searches only this backend, fails to find it, assumes that no crypto backend is available, and so does not include the crapi_object in the final link step. Commit7c85f3adf4("package/openscap: new package") took into account the fact that openscap isn't currently able to build if no crypto backend is provided (see [0]), and so made sure to force libgcrypt inclusion if libnss is not included. Since then, two fixes ([1] and [2]) have been integrated upstream to allow building openscap with any backend. Do not systematically enforce libgcrypt anymore through WITH_CRYPTO: rather than testing nss presence, and falling back to libgcrypt, allow both to be absent, and so relax the libgcrypt dependency to make it optional as well. Bring the two upstream patches allowing openscap build without any crypto backend. Those patches can be dropped once openscap v1.4.5 is released.

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.
