We hack around issues trying to reference OpenSSL from our Linux-Bionic builds here:
|
if(FORCE_ANDROID_OPENSSL) |
|
set(OPENSSL_CRYPTO_LIBRARY /usr/lib/x86_64-linux-gnu/libcrypto.so) |
|
set(OPENSSL_SSL_LIBRARY /usr/lib/x86_64-linux-gnu/libssl.so) |
|
# Things get more wrong. We need Desktop OpenSSL headers, but |
|
# /usr/include is special cased and forbidden. We need to copy |
|
# the headers to a different location and use them |
|
if(NOT DEFINED OPENSSL_INCLUDE_DIR) |
|
string(RANDOM LENGTH 24 _s) |
|
set(OPENSSL_INCLUDE_DIR ${CMAKE_CURRENT_BINARY_DIR}/${_s}/opensslheaders CACHE PATH "temporary directory") |
|
file(MAKE_DIRECTORY ${OPENSSL_INCLUDE_DIR}) |
|
file(COPY /usr/include/openssl DESTINATION ${OPENSSL_INCLUDE_DIR}) |
|
file(GLOB_RECURSE opensslconf /usr/include/*/openssl/*conf*.h) |
|
file(COPY ${opensslconf} DESTINATION ${OPENSSL_INCLUDE_DIR}/openssl/) |
|
endif() |
|
endif() |
This hack works with OpenSSL 1.1 headers, but breaks with OpenSSL 3.x headers, which check the target architecture. This breaks for our linux-bionic builds, which try to build for architectures that the multilib-compatible headers aren't set up to support.
This is the cause of the break requiring #102849 and makes our linux-bionic builds incompatible with Azure Linux 3.0.
