It appears that the latest gRPC release (1.7.2) does not compile with OpenSSL 1.1.0g. Both packages are the latest releases as of now (Nov 15, 2017). A quick googling returned a couple github issues such as this one:
https://github.com/grpc/grpc/issues/8801 gRPC build using cmake toolchain fails at grpc_print_google_default_creds_token as follows: Linking C executable grpc_print_google_default_creds_token libgrpc.so: undefined reference to `sk_pop_free' libgrpc.so: undefined reference to `EVP_DigestVerifyUpdate' libgrpc.so: undefined reference to `CRYPTO_set_locking_callback' libgrpc.so: undefined reference to `SSL_CTX_set_tlsext_servername_arg' libgrpc.so: undefined reference to `sk_value' libgrpc.so: undefined reference to `SSL_load_error_strings' libgrpc.so: undefined reference to `EVP_MD_CTX_create' libgrpc.so: undefined reference to `SSL_CTX_set_tlsext_servername_callback' libgrpc.so: undefined reference to `SSL_CTX_add_extra_chain_cert' libgrpc.so: undefined reference to `BIO_should_retry' libgrpc.so: undefined reference to `BIO_get_mem_data' libgrpc.so: undefined reference to `CRYPTO_num_locks' libgrpc.so: undefined reference to `EVP_MD_CTX_destroy' libgrpc.so: undefined reference to `sk_num' libgrpc.so: undefined reference to `SSL_library_init' libgrpc.so: undefined reference to `SSL_CTX_set_tmp_ecdh' libgrpc.so: undefined reference to `CRYPTO_set_id_callback' libgrpc.so: undefined reference to `SSL_set_tlsext_host_name' libgrpc.so: undefined reference to `BIO_pending' libgrpc.so: undefined reference to `sk_new_null' libgrpc.so: undefined reference to `EVP_DigestSignUpdate' libgrpc.so: undefined reference to `OpenSSL_add_all_algorithms' libgrpc.so: undefined reference to `sk_push' collect2: error: ld returned 1 exit status CMakeFiles/grpc_print_google_default_creds_token.dir/build.make:100: recipe for target 'grpc_print_google_default_creds_token' failed make[2]: *** [grpc_print_google_default_creds_token] Error 1 CMakeFiles/Makefile2:292: recipe for target 'CMakeFiles/grpc_print_google_default_creds_token.dir/all' failed make[1]: *** [CMakeFiles/grpc_print_google_default_creds_token.dir/all] Error 2 Makefile:127: recipe for target 'all' failed make: *** [all] Error 2 I'm wondering if this is a known issue and any patch is coming along the way (no issue with BoringSSL in third_party). Any comment/information about gRPC + OpenSSL would be appreciated. Thanks! Min -- You received this message because you are subscribed to the Google Groups "grpc.io" group.
