Failed tests -- what might be the build problem?

[Thomas Sharpless]

Building latest ceres solver release on Win10 with MSVC12 (VS2013 Community).

Using current Eigen distro + LAPACK & BLAS prebuilt from http://www.fi.muni.cz/~xsvobod2/misc/lapack/

Not using glog (would like to but I can't get it to link though it seems to build OK).

Everything builds without error but RUN_TESTS reports 15 failures, all of which seem to involve solver algorithms.

(summary below) The reported error in all cases was  ***Exception: Other  0.02 sec.

I hope someone more familiar with building ceres can recognize what might have gone wrong, and suggest how I might build it right.  My intended application is small scale bundle adjustment; so I don't care much about performance or capacity optimization -- I just need a solver that works.

1>  77% tests passed, 15 tests failed out of 66

Thomas,

Can you run one the failing tests from the command line and share the output. 

Say symmetric_linear_solver_test ?

Sameer,

I'd be happy to do that but have no clue how.  Can you give brief instructions?

[Sameer Agarwal]

there should be a bin directory containing a binary called symmetric_linear_solver_test that you should be able run from the command line.

OK, found that, ran it, here's the output

[Sameer Agarwal]

okay thats weird, because that test was failing in the log you sent out.

+Alex Stewart should have something to say here.

And this from iterative_schur_complement_solver_test.  Does this mean ceres is OK and the fault is really in RUN_TESTS?

Well, everything that happens inside Visual Studio is more or less weird :)

Tom,

What is the contents of:

<CERES_BUILD_DIR>/Testing/Temporary/LastTest.log

?  It should contain the output from all tests after you run make test.

[Thomas Sharpless]

Hi Alex

That log shows no output from any of the failed tests.  Example:

35/66 Testing: levenberg_marquardt_strategy_test

35/66 Test: levenberg_marquardt_strategy_test

Command: "C:/Users/tks/Projects/ceres-solver-master/build2-msvc2013/bin/Debug/levenberg_marquardt_strategy_test.exe" "--test_srcdir" "C:/Users/tks/Projects/ceres-solver-master/data"

Directory: C:/Users/tks/Projects/ceres-solver-master/build2-msvc2013/internal/ceres

"levenberg_marquardt_strategy_test" start time: Jan 29 12:38 Eastern Standard Time

Output:

----------------------------------------------------------

<end of output>

Test time =   0.02 sec
