Version 0.929: Test suite `poly_ts` fails

[badshah400]

When trying to build RPM packages for openSUSE for o2scl version 0.929, we find that the following test fails due to not achieving the right tolerance:

make[3]: Entering directory '/home/abuild/rpmbuild/BUILD/o2scl-0.929/src/other'
./poly_ts > poly.scr

A list of used compilers/libraries in case it helps:

• GCC 13.3
• GSL 2.8
• Eigen 3.4.0
• Armadillo 14.0.0
• MPFR 4.2.1
• HDF5 1.12.3
• fftw3 3.3.10

Thanks in advance.

Is this leap or tumbleweed or something else? Also, just out of curiosity, what version of boost is this? These multiprecision parts depend heavily on Boost...

[awsteiner]

I'm going to have to spend some time on this to figure out what's really going on, but in the mean time if you just use -DO2SCL_FAST_TEST then I think it will skip the test that is failing for you.

This is on Tumbleweed, using boost 1.85. Have not got around to testing on Leap yet. Thanks for looking into it.

Can confirm that passing "-DO2SCL_FAST_TEST" works (but see issue #38).

[awsteiner]

Even though -DO2SCL_FAST_TEST works, I want to look into more details about why it fails, so I'll leave this open for now...

In v0.929.2, all the OpenSUSE-associated actions now succeed. I added O2SCL_OPENSUSE and O2SCL_OPENSUSE_I386 flags to remove the tests which weren't passing. This obviously isn't a fix, so I won't close the issue, but at least this lets me know how it might be addressed in the future.
