Errors in NFLlib Installation

[lightnesscaster]

I followed the steps to install NFLlib (in Ubuntu 18.04), but I'm running into some problems. Everything is fine until I run make test. Then, I get the following result:

95% tests passed, 6 tests failed out of 122

Total Test time (real) = 11.14 sec

The following tests FAILED: 98 - run_nfllib_demo1048576_124_uint64_t_op (Child aborted) 100 - run_nfllib_demo1048576_124_uint64_t_func (Child aborted) 108 - run_nfl_eq1048576_124_uint64_t (Child aborted) 110 - run_nfl_neq1048576_124_uint64_t (Child aborted) 114 - run_poly_p1048576_124_uint64_t (SEGFAULT) 118 - run_poly_mpz1048576_124_uint64_t (SEGFAULT) Errors while running CTest Makefile:97: recipe for target 'test' failed make: *** [test] Error 8

Does anyone know why these tests are failing or what I can do about it?

I've also tried compiling the file nfllib_demo_main_func.cpp. But I get the following errors:

nfllib_demo_main_func.cpp: In function ‘int main()’: nfllib_demo_main_func.cpp:122:14: error: ‘CONFIG’ was not declared in this scope return run(); ^ nfllib_demo_main_func.cpp:122:22: error: no matching function for call to ‘run()’ return run(); ^ nfllib_demo_main_func.cpp:28:5: note: candidate: template<long unsigned int degree, long unsigned int modulus, class T> int run() int run() ^ nfllib_demo_main_func.cpp:28:5: note: template argument deduction/substitution failed: nfllib_demo_main_func.cpp:122:22: error: template argument 1 is invalid return run();

If anyone could help with these issues, I would be very appreciative.

Thanks for reproting! I can reproduce the issue with Release build, everything is fine with debug build, investigating...

[serge-sans-paille]

@lightnesscaster can you confirm that setting ulimit -s unlimited before running the test fixes the issue?

[tlepoint]

@serge-sans-paille, I wonder if for this problem of stack size, it would be possible to make those tests optional in cmake and output a warning when they fail?

@tlepoint if @lightnesscaster confirms the issue, i'll do it so!

Thanks for looking into this! I ran ulimit -s unlimited, but I'm still getting three errors. Is there something else I need to do? Also, I am still getting the same errors when trying to run nfllib_demo_main_func

98% tests passed, 3 tests failed out of 122

I think the issue is that some tests allocates big objects on the stack, instead of allocating them. I'll try and look into fixing this properly this week!

[lightnesscaster]

Has anybody made any progress on this? I would still like to be able to work with this library. Does anyone have any idea what is causing the demo errors?

[carlosaguilarmelchor]

@aguinet any news on this fix ? :)

[georgiagn]

Hello,

is the current commit working? For me, 56 tests failed out of 122 even after running ulimit -s unlimited.

Thanks, Georgia

[Kirija]

With the current commit, on a cluster on which I cannot perform a ulimit -s unlimited, only 3 tests fail with a segfault :

98% tests passed, 3 tests failed out of 122 Total Test time (real) = 229.97 sec The following tests FAILED: 98 - run_nfllib_demo1048576_124_uint64_t_op (SEGFAULT) 114 - run_poly_p1048576_124_uint64_t (SEGFAULT) 118 - run_poly_mpz1048576_124_uint64_t (SEGFAULT)

[carlosaguilarmelchor]

@serge-sans-paille @aguinet this is not my domain of expertise, can you make a fix in, say, one week ? If not I'll handle the issue myself but probably won't respect the coding standards you have.

[georgiagn]

My problem are not segfaults. For both Release and Debug, I'm getting the following output of make test:

Errors while running CTest
Makefile:97: recipe for target 'test' failed

Any clue on what causes the failures? make and make install work fine otherwise. If I run cmake . ; make under tests/, I get: Building CXX object CMakeFiles/ntt_multi.dir/multi0.o []/NFLLib/tests/multi0.cpp:3:10: fatal error: nfl.hpp: No such file or directory

Any help would be highly appreciated :)
