Hi, I am facing the build issue with OpenJDK11(jdk11u). I am trying to build jdk11u on Windows and I am getting the below error.
#################### ./src/java.base/windows/native/libnet/net_util_md.c(792): error C2065: 'TCP_INITIAL_RTO_NO_SYN_RETRANSMISSIONS': undeclared identifier make[3]: *** [Lib-java.base.gmk:44: /cygdrive/d/source/mirrors_github_jdk11u/build/windows-x86_64-normal-server-release/support/native/java.base/libnet/net_util_md.obj] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [make/Main.gmk:215: java.base-libs] Error 2 ERROR: Build failed for target 'images' in configuration 'windows-x86_64-normal-server-release' (exit code 2) Stopping sjavac server ################### I found that the back-port of JDK-8250521 <https://bugs.openjdk.java.net/browse/JDK-8250521> is causing this failure. My environment details are as follows. OS: Windows Server 2016 Standard, Visual Studio professional 2017 version 15.2(26430.14) When I updated my Visual Studio to 15.9.42(which contains Windows 10 SDK(10.0.17134.0)) the problem went away. My question is do we have a minimum supported Visual Studio(15.9.42) to build jdk11u(11.0.14) ?. If this is not the case then I would like to fix this build failure. Thanks, Vyom
