Instead of hardcoding -lssl -lcrypto as the flags needed to build mkimage with FIT signature enabled, use pkg-config when available. This allows to properly support cases where static linking is used, which requires linking with -lz, since OpenSSL uses zlib internally.
We gracefully fallback on the previous behavior of hardcoding -lssl -lcrypto if pkg-config is not available or fails with an error. Signed-off-by: Thomas Petazzoni <thomas.petazz...@free-electrons.com> --- Changes since v1: - Use both libssl and libcrypto when calling pkg-config, because some symbols of libcrypto are used directly by u-boot. This wasn't visible with static linking because -lssl -lcrypto are returned by pkg-config, but was visible with dynamic linking since only -lssl was returned by pkg-config. tools/Makefile | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/tools/Makefile b/tools/Makefile index 4bbb153..8ff9c2e 100644 --- a/tools/Makefile +++ b/tools/Makefile @@ -122,7 +122,8 @@ endif # MXSImage needs LibSSL ifneq ($(CONFIG_MX23)$(CONFIG_MX28)$(CONFIG_FIT_SIGNATURE),) -HOSTLOADLIBES_mkimage += -lssl -lcrypto +HOSTLOADLIBES_mkimage += \ + $(shell pkg-config --libs libssl libcrypto 2> /dev/null || echo "-lssl -lcrypto") endif HOSTLOADLIBES_dumpimage := $(HOSTLOADLIBES_mkimage) -- 2.1.0 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
