Unable to run drmemory v2.5.0 on RHEL 8.2

[shahsb]

I downloaded Dr. Memory v2.5..0 from https://github.com/DynamoRIO/drmemory/releases/download/release_2.5.0/DrMemory-Linux-2.5.0.tar.gz

Extracted & set the environment variables properly.

When I tried to run my app using command: "drmemory -- myapp myapp_args"

I got this error: "drmemory: No such file or directory"

so I tried to do ldd & got this error: ldd drmemory not a dynamic executable

Next, I tried running readelf and got below output:

readelf -d drmemory

The same drmemory v2.5.0 is working fine on windows platform.

So wondering: Is Dr. Memory ever tested on Red Hat platform?

Any workaround or solution to this would help. Thanks in advance.

Maybe the bin64 version works better. I just tried on RHEL 7.6 and a) failed to find libunwind and b) when I set LD_LIBRARY_PATH to point to a fairly recent libunwind, it hangs fairly quickly

set_tid_address(0x7ffdf7c529d0)         = 20622
set_robust_list(0x7ffdf7c529e0, 24)     = 0
rt_sigaction(SIGRTMIN, {0x7ffdf6f5a790, [], SA_RESTORER|SA_SIGINFO, 0x7ffdf6f635d0}, NULL, 8) = 0
rt_sigaction(SIGRT_1, {0x7ffdf6f5a820, [], SA_RESTORER|SA_RESTART|SA_SIGINFO, 0x7ffdf6f635d0}, NULL, 8) = 0
rt_sigprocmask(SIG_UNBLOCK, [RTMIN RT_1], NULL, 8) = 0
getrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM64_INFINITY}) = 0
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0} ---
gettid()                                = 20622
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0} ---

Looks like the stack is hosed.

RHEL 8.2 is a bit better

and it works OK with LD_LIBRARY_PATH pointing to libunwind.so
