Later, commit bfb713ea53c7 ("perf tools: Fix arm64 build by generating unistd_64.h") added a dependency to libperf to guarantee that this header was created before building libperf or perf itself. However, libjvmti also requires this header but does not depend on libperf, leading to build failures such as: In file included from /usr/include/sys/syscall.h:24, from /usr/include/syscall.h:1, from jvmti/jvmti_agent.c:36: tools/arch/arm64/include/uapi/asm/unistd.h:2:10: fatal error: asm/unistd_64.h: No such file or directory 2 | #include Fix this by ensuring that libperf is built before libjvmti, so that unistd_64.h is always available.
