Hi, Following Georg Richter recommendations for compiling MariaDB on Windows 64bit, with OpenSSL using the following cmake commands: cmake .. -DWITH_SSL=system -G "Visual Studio 15 2017 Win64" cmake --build . --config relwithdebinfo --target package However, several recipes fail to build, for the following errors: "builddir\mysys_ssl\mysys_ssl.vcxproj" (default target) (8) -> (ClCompile target) -> c:\users\braiam\src\mariadb-10.3.9\mysys_ssl\my_crypt.cc(42): error C3861: 'bzero': identifier not found [C:\Users\br aiam\src\mariadb-10.3.9\bld\mysys_ssl\mysys_ssl.vcxproj] and "builddir\package.vcxproj" (default target) (1) -> "builddir\ALL_BUILD.vcxproj" (default target) (3) -> "builddir\libmariadb\sha256_password.vcxproj" (default target) (205) -> (Link target) -> sha256_pw.obj : error LNK2019: unresolved external symbol BIO_free referenced in function auth_sha256_client [C:\User s\braiam\src\mariadb-10.3.9\bld\libmariadb\sha256_password.vcxproj] sha256_pw.obj : error LNK2019: unresolved external symbol BIO_new_mem_buf referenced in function auth_sha256_client [ builddir\libmariadb\sha256_password.vcxproj] sha256_pw.obj : error LNK2019: unresolved external symbol RSA_size referenced in function auth_sha256_client [C:\User s\braiam\src\mariadb-10.3.9\bld\libmariadb\sha256_password.vcxproj] sha256_pw.obj : error LNK2019: unresolved external symbol RSA_public_encrypt referenced in function auth_sha256_clien t [builddir\libmariadb\sha256_password.vcxproj] sha256_pw.obj : error LNK2019: unresolved external symbol RSA_free referenced in function auth_sha256_client [C:\User s\braiam\src\mariadb-10.3.9\bld\libmariadb\sha256_password.vcxproj] sha256_pw.obj : error LNK2019: unresolved external symbol PEM_read_bio_RSA_PUBKEY referenced in function auth_sha256_ client [builddir\libmariadb\sha256_password.vcxproj] sha256_pw.obj : error LNK2019: unresolved external symbol ERR_clear_error referenced in function auth_sha256_client [ builddir\libmariadb\sha256_password.vcxproj] builddir\libmariadb\RelWithDebInfo\sha256_password.dll : fatal error LNK1120: 7 unresol ved externals [builddir\libmariadb\sha256_password.vcxproj] Using the OpenSSL 1.1.0i 64bit binaries from Shinning Light Productions. Using the 1.0.2p version produce even more linking errors. I also used FireDaemon but failed. Is there a recommended Windows binary for compiling? Or do I need to compile my own openssl? -- Braiam Peguero
