Two after-build tests fail for the intel TBB source:
make rml (which by default also makes rml_test - which fails):
./test_rml_mixed.exe Assertion my_make_server_routine failed on line 86 of file ../../src/rml/client/rml_factory.h ../../build/Makefile.rml:150: recipe for target 'rml_test' failed make[1]: *** [rml_test] Aborted (core dumped) make[1]: Leaving directory '/path_to_src_dir/tbb43_VERSIONoss/build/linux_intel64_gcc_cc5.2.0_libc2.22_kernel4.2.0_debug' Makefile:50: recipe for target 'rml' failed make: *** [rml] Error 2
VERSION is confirmed to atleast be either 20150611 or 20150728.
Also the make-target `test` fails, at some point:
TBB Warning: RML might limit the number of workers to 7 while 15 is requested. Call stack info (6): ./test_tbb_fork.exe(_Z16print_call_stackv+0x44)[0x4045ba] ./test_tbb_fork.exe(_Z11ReportErrorPKciS0_S0_+0x1d)[0x4046a3] ./test_tbb_fork.exe(_Z8TestMainv+0x377)[0x404f45] ./test_tbb_fork.exe(main+0x2d)[0x404a1a] /usr/lib/libc.so.6(__libc_start_main+0xf0)[0x7f976d601610] ./test_tbb_fork.exe(_start+0x29)[0x4044a9] ../../src/test/test_tbb_fork.cpp:195, assertion 0: Hang after fork ../../build/Makefile.test:251: recipe for target 'test_tbb_plain' failed make[1]: *** [test_tbb_plain] Aborted (core dumped) make[1]: Leaving directory '/path_to_src_dir/tbb43_VERSIONoss/build/linux_intel64_gcc_cc5.2.0_libc2.22_kernel4.1.8_debug' Makefile:44: recipe for target 'test' failed make: [test] Error 2 (ignored)
The error in the `rml` target is that the assertion failed that 'factory' could not be opened - at least that's the comment above the critical line:
Assertion my_make_server_routine failed on line 86 of file ../../src/rml/client/rml_factory.h
Same thing for the VERSION.
I could not check why both assertions fail (first: fail to open `factory`; second: thread hangs even after pkill and reaches code that shouldn't be reached). The issue not only exists on GCC5 but I also tested it on GCC4.9.
Any idea why the tests fail? Bug in the source or libraries?

This is *not* the rml I'm just running 'make && make test'.
Could you please double-check this? I.e.,
TBB_VERSION=1 LD_LIBRARY_PATH=. ./test_tbb_fork.exe 2>&1|grep RML
returns
TBB: RML shared
when shared RML is in use, and
TBB: RML private
when no shared RML found.

Hi
Archlinux update the TBB stack to 2021.4 in [testing] (include tbb4py)
update to build script for use system tbb instead bundled (downloaded from APT) get the same output (NULL platform behavior) when run clinfo

Hi,
Could you please let us know the command used to generate the log mentioned in the previous post?
>> about missing IMRL library now is complete
Does this mean that your issue regarding the IMRL library was resolved?
Could you please do let us know the exact issue you are facing now?
Thanks & Regards,

Hi
>>Could you please let us know the command used to generate the log mentioned in the previous post?
simply `strace <app>`
`strace clinfo`
>>Does this mean that your issue regarding the IMRL library was resolved?
the missing library is now resolved, because Archlinux TBB package include it
https://archlinux.org/packages/testing/x86_64/tbb/files/
>>Could you please do let us know the exact issue you are facing now?
the same issue without the IMRL library (the root of the problem i think in the first time)
`clinfo` show:

Hi,
Thanks for providing the details.
Could you please confirm whether the log provided in your previous reply is a complete log?
If not please provide us a complete log so that it would be helpful for us to get some more insights.
Please find the attached file for the output of "strace clinfo" command that we got on our end.
could you please let us know if you are looking for any specific information from the output of clinfo?
Thanks & Regards,

strace clinfo (see the attached file esee.log)
viewing you log, have the same output like me (the last part, talking about NULL platform behavior)
so maybe is the output in a normal execution

>> oneAPI suit also complains about libirml.so library
libirml.so is a special purpose library that is used only with tbb4py package. Regular oneTBB and Intel OpenCL runtimes do not require this library. Pay attention that strace does not show errors but only logs return statuses of particular system function. I.e. the fact that libirml.so is not found is not a error, it is expected behavior when oneTBB runtime uses dlopen to query if libirml.so present or not.

Hi,
I think this issue has been resolved and we will no longer respond to this thread. If you require additional assistance from Intel, please start a new thread. Any further interaction in this thread will be considered community only.
Thanks!
