hope can be fixed soon.. waiting for new static analyzer..

fxcoudert · 2020-05-08T23:04:40Z

The Mojave failure is a semi-random parallel-build issue (sadly). Hopefully it won't trigger on the next build.

alebcay · 2020-05-09T07:26:01Z

imake still needs revision bump:

Homebrew internals also might need some adjustment for gcc 10:

brew received preliminary support for GCC 10, but not all cases were tested because GCC 10 wasn't released yet (support was needed as Fedora 32 shipped with GCC 10 despite it not being released). The above error is specific to using GCC 10 from a formula.

I've fixed the error here: Homebrew/brew#7528

version_suffix needs to also be modified in the GCC formula similarly to slice \d+ rather than \d.

(Also: should we add gcc@9 versioned formula here?)

SMillerDev · 2020-05-09T10:09:45Z

Also: should we add gcc@9 versioned formula here?

Only if it's needed for homebrew formula.

Bo98 · 2020-05-09T10:12:31Z

Or someone inevitably asks for it.

fxcoudert · 2020-05-09T10:13:22Z

should we add gcc@9 versioned formula here?

I am not sure what the current criteria are, and whether they changed from before. But GCC 9 is supported, and historically older versions of GCC have large numbers of downloads. I would argue it makes sense to carry it, because it is very useful to users (especially given the high time and disk requirements of building one's own compiler from source).

Bo98 · 2020-05-09T10:16:55Z

The requirements are the same as far as I know. The only thing new is that we have a deprecation system now, but that can't be applied here since there isn't a specific EOL date yet.

fxcoudert · 2020-05-09T10:29:22Z

⚠️ This should be not be merged until a new brew is shipped with Homebrew/brew#7528 in

fxcoudert · 2020-05-09T13:10:14Z

It builds and tests gcc fine, then gets into an infinite loop of brew install gcc once it moves to testing openblas:

==> Running Formulae#formula!(openblas)
==> brew install gcc
==> brew install gcc
==> brew install gcc

Bo98 · 2020-05-10T11:53:28Z

Ah, I see GFortran has been making some breaking changes...

Build failure:

adios2 - GFortran 10 incompatibility (type mismatch)
arpack - GFortran 10 incompatibility (rank mismatch) - patch at https://github.com/opencollab/arpack-ng/commit/9418632214acf6d387896ab29a8f5bdff2d4e38a.patch?full_index=1
augustus - this line needs to use version_suffix
cp2k - fails because it needs scalapack which has a build failure
dungeon - GFortran 10 incompatibility (different than the other failures: Error: BOZ constant at (1) uses nonstandard postfix syntax [see '-fno-allow-invalid-boz'])
dynare - fails because it needs arpack which has a build failure
eccodes - fails because it needs netcdf which has a build failure
libbi - fails because it needs netcdf which has a build failure
gcc@9 - docs fail to build:

../../gcc/doc//invoke.texi:1785: Unknown command `9-20200509-55160-10y5gr9/gcc-9.3.0/build/gcc/../../gcc'.
../../gcc/doc//invoke.texi:1784: @include `/private/tmp/gcc/../libiberty/at-file.texi': No such file or directory.

ipopt - GFortran 10 incompatibility (type mismatch) in the mumps resource - reported at https://listes.ens-lyon.fr/sympa/arc/mumps-users/2020-05/msg00000.html
mpich - GFortran 10 incompatibility - reported at https://lists.mpich.org/pipermail/discuss/2020-January/005863.html - they do not currently plan on fixing the issue and currently suggest the -fallow-argument-mismatch workaround
netcdf - GFortran 10 incompatibility (rank mismatch) - reported at Fails to build with gcc 10 Unidata/netcdf-fortran#212
nwchem - fails because it needs scalapack which has a build failure
octave - fails because it needs arpack which has a build failure
petsc - fails because it needs netcdf and scalapack which have a build failure
petsc-complex - fails because it needs netcdf and scalapack which have a build failure
pgplot - GFortran 10 compatibility (type mismatch) - not been updated in 19 years - (also the build doesn't properly fail on the system call exit code - can we split up that combined system line into separate ones?)
pnetcdf - GFortran 10 incompatibility (type mismatch)
scalapack - GFortran 10 incompatibility (rank mismatch) - reported at ScaLAPACK fails with GCC 10 Reference-ScaLAPACK/scalapack#21
scipy - GFortran 10 incompatibility (rank mismatch) - patch at https://github.com/scipy/scipy/commit/2190a7427a8d10a3a506294e87ff1330c426cb63.patch?full_index=1 - will be included in 1.5.0

Most of the GFortran 10 incompatibilities can be fixed with -fallow-argument-mismatch (useful for, say, pgplot which probably won't be updated) - however if that is used, it might be worth leaving a comment that it should be removed if/when upstream fix the problem (the flag is "strongly discouraged").

Test failure:

csound - known random failure
qrupdate - GFortran 10 incompatibility (type mismatch) - not been updated in 8 years but it is just a test failure and we can easily pass -fallow-argument-mismatch
~~r - the gss resource has gone missing (replaced by gss_2.2-0.tar.gz)~~ Handled in pcre2 10.35 #54520 it appears.

Audit failures (can be resolved in separate PRs first if desired):

cgns - shim reference in include/cgnsBuild.defs
hdf5 - shim references in share/hdf5/libhdf5.settings and libhdf5 library (dylib & a)
[email protected] - same as above
[email protected] - same as above
open-mpi - shim reference in bin/ompi_info and bin/orte-info
plplot - shim references in share/plplot5.15.0/examples/c++/Makefile and share/plplot5.15.0/examples/c/Makefile - these files should not be installed in the first place
root - shim references in include/root/compiledata.h, lib/root/libProof.so and lib/root/libCore.so

Bo98 · 2020-05-11T13:38:23Z

brew 2.2.16 is now released btw

SMillerDev · 2020-05-13T14:59:43Z

Fixing all of the software that depends on GCC to work with GCC 10.

SMillerDev · 2020-05-26T21:35:51Z

Most of the GFortran 10 incompatibilities can be fixed with -fallow-argument-mismatch [...] (the flag is "strongly discouraged").

How about we add this as a solution and add an audit to make sure next package updates are warned about it?

sjackman · 2020-05-26T21:36:47Z

Could gcc be an alias to [email protected]?

On Homebrew on Linux, bottles are built using Ubuntu 16.04 LTS (Xenial Xerus), and the default version of GCC is 5, which is the GCC version of Ubuntu 16. On Linux, gcc could then be an alias to [email protected].

Here's a related PR on Linuxbrew-core https://github.com/Homebrew/linuxbrew-core/pull/20241

cc @iMichka

fxcoudert · 2020-07-03T09:22:45Z

Failures are:

muparser, needs a revision bump
mlpack, I don't understand it right now
x264, needs a revision bump (for 10.13 only)

Test failure:

adios2
ncview, only on 10.14… random fluke?

Pre-existing audit failures:

hdf5, [email protected], [email protected]
netcdf, pnetcdf
pgplot
plplot

None of the failures are for high-usage formula, except x264, but it only affects 10.13 (5.94% of users). I would like to merge in the current state, because:

this PR bit rots super fast, due to the many revisions
I will quickly rebuild the needed bottle for x264
I will investigate the rest later today

@Homebrew/core what do you think?
