Yes the whole test framework needs some love and attention.

which version of ghc were you using?

GeorgeCo commented 5 years ago

on ghc 8.6.5 cabal install hmatrix-tests fails with

[3 of 4] Compiling Numeric.LinearAlgebra.Tests ( src/Numeric/LinearAlgebra/Tests.hs, dist/build/Numeric/LinearAlgebra/Tests.p_o ) Simplifier ticks exhausted When trying UnfoldingDone $j_s1mHf To increase the limit, use -fsimpl-tick-factor=N (default 100).

If you need to increase the limit substantially, please file a bug report and indicate the factor you needed.

If GHC was unable to complete compilation even with a very large factor (a thousand or more), please consult the "Known bugs or infelicities" section in the Users Guide before filing a report. There are a few situations unlikely to occur in practical programs for which simplifier non-termination has been judged acceptable.

To see detailed counts use -ddump-simpl-stats Total ticks: 4513444 cabal: Leaving directory '/var/folders/df/5d_dsdrx1dn4j30ktsgn8blh0000gp/T/cabal-tmp-3611/hmatrix-tests-0.19.0.0' cabal: Error: some packages failed to install: hmatrix-tests-0.19.0.0-CBikoZo0LFRBCtRsbHuMzR failed during the building phase. The exception was: ExitFailure 1

Can anybody install it on ghc 8.6.5? Also fails if I install with tick-factor of 200. With tick factor of 1000 it was consuming over 50 gb of (virtual) memory before I killed it.

I accidentally closed this but it should still be open but I can't see how to reopen it.

what version of ghc was that?

For ghc corresponding to lts-10.9, also tried 12.14. Edit: just tried it with lts 13.21, it worked out
