Buildroot commit1f4b4ccde7("package/opensc: security bump to version 0.26.0") bumped opensc from 0.24 to 0.26, and the build started failing with: pkcs11-tool.c:7854:45: warning: implicit declaration of function 'EVP_bf_cbc'; did you mean 'EVP_sm4_cbc'? [-Wimplicit-function-declaration] on configurations that have BR2_PACKAGE_LIBOPENSSL_ENABLE_BLOWFISH disabled (it is not explicitly selected by this package). Our initial fix was to simply select BR2_PACKAGE_LIBOPENSSL_ENABLE_BLOWFISH, but when investigating when EVP_bf_cbc() started being used in OpenSC, we discovered it has been in use for a while... but in code that kept being disabled from version to version as it was broken (upstream bug https://github.com/OpenSC/OpenSC/issues/1796), but it was apparently forgotten to be disabled again for 0.26 (the issue is still open). Therefore, we opted to continue disabling this known broken part of the code, and submit an upstream PR for that https://github.com/OpenSC/OpenSC/pull/3303, which ultimately will clarify what is the right fix. In the mean time, this allows to fix the build issue.

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.
