From: Thomas Richter <tmri...@linux.ibm.com> With Java 11 there is no seperate JRE anymore.
Details: https://coderanch.com/t/701603/java/JRE-JDK Therefore the detection of the JRE needs to be adapted. This change works for s390 and x86. I have not tested other platforms. Committer testing: Continues to work with the OpenJDK 8: $ rm -f ~acme/lib64/libperf-jvmti.so $ rpm -qa | grep jdk-devel java-1.8.0-openjdk-devel-1.8.0.222.b10-0.fc30.x86_64 $ git log --oneline -1 a51937170f33 (HEAD -> perf/core) perf build: Add detection of java-11-openjdk-devel package $ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ; make -C tools/perf O=/tmp/build/perf install > /dev/null 2>1 $ ls -la ~acme/lib64/libperf-jvmti.so -rwxr-xr-x. 1 acme acme 230744 Sep 24 16:46 /home/acme/lib64/libperf-jvmti.so $ Suggested-by: Andreas Krebbel <kreb...@linux.ibm.com> Signed-off-by: Thomas Richter <tmri...@linux.ibm.com> Tested-by: Arnaldo Carvalho de Melo <a...@redhat.com> Cc: Heiko Carstens <heiko.carst...@de.ibm.com> Cc: Hendrik Brueckner <brueck...@linux.ibm.com> Cc: Vasily Gorbik <g...@linux.ibm.com> Link: http://lore.kernel.org/lkml/20190909114116.50469-4-tmri...@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <a...@redhat.com> --- tools/perf/Makefile.config | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/perf/Makefile.config b/tools/perf/Makefile.config index a269d78456b6..46f7fba2306c 100644 --- a/tools/perf/Makefile.config +++ b/tools/perf/Makefile.config @@ -924,7 +924,7 @@ ifndef NO_JVMTI JDIR=$(shell /usr/sbin/update-java-alternatives -l | head -1 | awk '{print $$3}') else ifneq (,$(wildcard /usr/sbin/alternatives)) - JDIR=$(shell /usr/sbin/alternatives --display java | tail -1 | cut -d' ' -f 5 | sed 's%/jre/bin/java.%%g') + JDIR=$(shell /usr/sbin/alternatives --display java | tail -1 | cut -d' ' -f 5 | sed -e 's%/jre/bin/java.%%g' -e 's%/bin/java.%%g') endif endif ifndef JDIR -- 2.21.0
