qmake：当设置QMAKE_CXX = clang ++ qmake使用g ++进行链接时

Question

当使用.cpp强制在安装了gcc和clang的系统上使用clang时，clang ++用于编译-fsanitize=unsigned-integer-overflow文件，但g ++用于最终链接。当使用UBSAN时会出现问题，因为g ++不知道clang选项--- buildpack: https://github.com/cloudfoundry/java-buildpack.git memory: 1024M env: APPLICATION_URL: http://bignibou-server.cfapps.io/ APPLICATION_MAIL_NO_REPLY_ADDRESS: balteo@bignibou-server.cfapps.io SPRING_PROFILES_ACTIVE: cloud applications: - name: bignibou-server path: bignibou-server/build/libs/bignibou-server.jar env: APPLICATION_GOOGLE_API_KEY: ****************** - name: bignibou-batch path: bignibou-batch/build/libs/bignibou-batch.jar no-hostname: true no-route: true command: null health-check-type: none env: JAVA_OPTS: -Dspring.batch.job.names=messagesDigestMailingJob 。如何强制qmake使用clang进行链接呢？

Answer 1

除了为QMAKE_LINK=clang++指定的内容外，您还需要指定QMAKE_CXX。
