Hi I'm on recent current (r338418) trying to compile LineageOS 15.1 (an Android ROM). linux_base-c7 is installed linux and linux64 loaded proc, fd, linprocfs and linsysfs mounted I managed to get it to about 85%, but it fails during the following call: java -Xms16M -Xmx2048M -jar /android/LOS/out/host/linux-x86/framework/dx.jar --dex --output=/android/LOS/out/target/common/obj/JAVA_LIBRARIES/core-libart_intermediates/with-local/ --min-sdk-version=27 --core-library /android/LOS/out/target/common/obj/JAVA_LIBRARIES/core-libart_intermediates/classes.jar If I use FreeBSD openjdk8, this command works, however part of the earlier build involves loading a linux library in the jvm, which fails with FreeBSD's openjdk With Ubuntu 16.04 openjdk I got several SIGSEGV. % kdump | grep -A3 -B3 SIGSEGV 53182 java RET linux_mmap2 34422685696/0x803c08000 53182 java CALL linux_mmap2(0x803c08000,0xa000,0x3,0x32,0xffffffffffffffff,0) 53182 java RET linux_mmap2 34422685696/0x803c08000 53182 java PSIG SIGSEGV caught handler=0x8026b8f40 mask=0x4 code=SEGV_MAPERR 53182 java CALL linux_rt_sigreturn(0) 53182 java RET linux_rt_sigreturn JUSTRETURN 53182 java CALL linux_clock_gettime(0x1,0x80072a9d0) -- 53182 java CALL linux_mprotect(0x800623000,0x1000,0x1) 53182 java RET linux_mprotect 0 53182 java CALL linux_mprotect(0x800623000,0x1000,0x3) 53182 java PSIG SIGSEGV caught handler=0x8026b8f40 mask=0x4 code=<invalid=0xc> 53182 java RET linux_mprotect 0 53182 java CALL linux_mprotect(0x800622000,0x1000,0) 53182 java RET linux_mprotect 0 -- 53182 java CALL linux_mprotect(0x800623000,0x1000,0x1) 53182 java CALL linux_sys_futex(0x80400a854,0x80,0x8b,0,0x80400a800,0x45) 53182 java RET linux_mprotect 0 53182 java PSIG SIGSEGV caught handler=0x8026b8f40 mask=0x4 code=<invalid=0xc> 53182 java CALL linux_sys_futex(0x8042b3d54,0x80,0x1,0,0x8042b3d00,0) 53182 java CALL linux_mprotect(0x800623000,0x1000,0x3) 53182 java RET linux_mprotect 0 -- 53182 java RET linux_clock_gettime 0 53182 java CALL gettimeofday(0x800728a70,0) 53182 java RET gettimeofday 0 53182 java PSIG SIGSEGV caught handler=0x8026b8f40 mask=0x4 code=SEGV_MAPERR 53182 java CALL gettimeofday(0x81a5c7510,0) 53182 java RET gettimeofday 0 53182 java CALL linux_clock_gettime(0x1,0x800729050) -- 53182 java RET linux_clock_gettime 0 53182 java CALL linux_mprotect(0x800623000,0x1000,0x1) 53182 java CALL linux_sys_futex(0x80417c654,0x80,0x17b,0,0x80417c600,0xbd) 53182 java PSIG SIGSEGV caught handler=0x8026b8f40 mask=0x4 code=<invalid=0xc> 53182 java RET linux_mprotect 0 53182 java CALL linux_mprotect(0x800623000,0x1000,0x3) 53182 java RET linux_mprotect 0 -- 53182 java RET linux_clock_gettime 0 53182 java CALL linux_mprotect(0x84c3ef000,0x25000,0x3) 53182 java RET linux_mprotect 0 53182 java PSIG SIGSEGV caught handler=0x8026b8f40 mask=0x4 code=SEGV_MAPERR 53182 java CALL linux_clock_gettime(0x1,0x8007290e0) 53182 java RET linux_clock_gettime 0 53182 java CALL linux_rt_sigreturn(0) -- 53182 java CALL linux_clock_gettime(0x1,0x81a5c7a00) 53182 java RET linux_clock_gettime 0 53182 java CALL linux_mprotect(0x84c414000,0xa000,0x3) 53182 java PSIG SIGSEGV caught handler=0x8026b8f40 mask=0x4 code=SEGV_MAPERR 53182 java RET linux_mprotect 0 53182 java CALL linux_clock_gettime(0x1,0x800729060) 53182 java RET linux_clock_gettime 0 -- 53182 java RET linux_clock_gettime 0 53182 java CALL linux_clock_gettime(0x1,0x800729390) 53182 java RET linux_clock_gettime 0 53182 java PSIG SIGSEGV caught handler=0x8026b8f40 mask=0x4 code=<invalid=0x3> 53182 java CALL linux_rt_sigprocmask(0x1,0x800729320,0,0x8) 53182 java RET linux_rt_sigprocmask 0 53182 java CALL linux_getcwd(0x802d449e0,0x7d0) I thought it might be related to security.bsd.map_at_zero, but setting it to 1 didn't change anything I would appreciate some guidance Thanks
