zlib is not mandatory with mbedtls, only optional, however as mbedtls does not provide a pkg-config file, we assume that if zlib is available, we must link with it to avoid a build failure when linking statically with a zlib-enabled mbedtls. This change was pushed upstream with7b8efe11dband is in buildroot since the bump to version 7.1.4 with commit0c80245ddb. However, this change will raise a build failure if ZLIB_LIBRARIES is used when zlib is not found. This patch is fixing this build failure. However, it should be noted that the compression support in mbedtls is only enabled if BR2_PACKAGE_MBEDTLS_COMPRESSION=y. So we can have a situation where mbedtls is enabled, zlib is enabled, but mbedtls is not using zlib and as a result, since version 7.1.4, rttyt will needlessly link with zlib in such a situation. The only sane way to fix this is to use pkg-config, but as mbedtls apparently doesn't provide any .pc file, we leave it as it is.

|
|
|
|
Building with mbedtls but without zlib will result in the following
|
|
build failure:
|
|
|
|
-- Found MbedTLS: /home/peko/autobuild/instance-0/output-1/per-package/rtty/host/powerpc64-buildroot-linux-gnu/sysroot/usr/lib/libmbedtls.so (found version "2.16.7")
|
|
-- Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)
|
|
-- Select MbedTLS(PolarSSL) as the SSL backend
|
|
