I wanted to create a pull request in OpenJDK, but I struggle to make the tests of tier 1 pass before making any changes.
At some point, I was able to run the tests of tier1, but got some failures (roughly about 60). Then I noticed that the document says "Building of Hotspot Gtest suite requires the source code of Google Test framework". So, I downloaded the source code and reconfigured the Toolchain, adding -with-gtest to the previously used config command, resulting in: bash configure --with-boot-jdk=/cygdrive/c/jDev/java-x64/jdk-15.0.1+9/ --with-jtreg=/cygdrive/c/jDev/jtreg/ --with-gtest=/cygdrive/c/jDev/googletest-release-1.8.1/ But now I cannot run the tests anymore. The test build exits with the message "ERROR: Build failed for target 'run-test-tier1' in configuration 'windows-x86_64-server-release' (exit code 2)". Further up the logs, I found the following messages: Creating support/test/lib-test/jtreg/native/bin/jvm-test-launcher.exe from 1 file(s) make[3]: *** No rule to make target '/cygdrive/c/jdev/java-x64/jdk-15~2.1_9/bin//cygdrive/c/windows/system32/vcruntime140_1.dll', needed by '/cygdrive/c/users/matthiasp/git/jdk/build/windows-x86_64-server-release/images/test/hotspot/gtest/server/vcruntime140_1.dll'. Stop. make[3]: *** Waiting for unfinished jobs.... make[2]: *** [make/Main.gmk:675: test-image-hotspot-gtest] Error 2 Notice the double slash in the target path. Also, it starts with the path to the boot JDK, but then it has "jdk-15~2.19" instead of "jdk-15.0.1+9". Apparently, the paths got messed up here. Do you have any idea what that could be, or what steps can help to solve this? As you can see, I am on Windows with Cygwin. Also, I installed Visual Studio 2019 Community Edition, adding "MSVC v142 - VS 2019 C++-ARM-Buildtools (v14.28)" to the core installation. Thanks, Matthias Perktold
