cmake - Can't run ctest unless the test executable is named "tests" -

-

i trying cmake/ctest work. problem ctest not seem pick test executable unless named tests.

in minimal example project have single cmakelists.txt file:

cmake_minimum_required(version 3.0) project(myproject c) enable_testing() set(test_exe_name tests) add_executable(${test_exe_name} test_main.c) add_test(name "my tests" command ${test_exe_name})

...and simple test program, test_main.c, passes:

int main() {   return 0; }

i can run make && make test, , fine long test_exe_name set tests. however, when change executable name else, e.g. mytests, following error:

could not find executable tests looked in following places: tests tests release/tests release/tests debug/tests ...

what missing?

according cmake manual add_test() test name may not contain spaces:

the test name may not contain spaces, quotes, or other characters special in cmake syntax.

in problematic example, test named "my tests". changing test name "my_tests" solves problem.

apparently, part of test name after space character (i.e. "tests") interpreted test executable name.

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
