I think something similar was on this list a couple of days ago, it's |
| 21 |
a missing include (that wasn't neccessary before Qt5.15), there's 21 |
| 22 |
similar bugs filed already c.f.[1]. |
| 23 |
|
| 24 |
A quick and easy fix for this problem should be this: |
| 25 |
|
| 26 |
1. create a file /etc/portage/env/missing-qpainterpath-flags and insert |
| 27 |
this line: |
| 28 |
|
| 29 |
==== |
| 30 |
CXXFLAGS="${CXXFLAGS} -include QPainterPath" |
| 31 |
==== |
| 32 |
|
| 33 |
2. add the line |
| 34 |
|
| 35 |
==== |
| 36 |
=media-sound/cadence-0.9.0-r4 missing-qpainterpath-flags |
| 37 |
==== |
| 38 |
|
| 39 |
to /etc/portage/package.env (or /e/p/package.env/qpainterpath.env or |
| 40 |
some such if you've "directoryfied" your package.env (can you?) ;) |
| 41 |
|
| 42 |
[add more lines for specific package versions and revs for the same |
| 43 |
problem, see [1] for candidates] |
| 44 |
|
| 45 |
Yes, that is *quite an ugly hack*, but could be handy while stuff get's |
| 46 |
patched to work with that specific change of Qt5.15... |
| 47 |
|
| 48 |
FWIW: that includes that QPainterPath header in _all_ C++ sources, but |
| 49 |
what the hey, compilers are so good today, that they throw away |
| 50 |
anything unused, so it should not matter. It'll slow down the compile |
| 51 |
a bit... |
| 52 |
|
| 53 |
Once e.g. media-sound/cadence is fixed and revbumped/versionbumped, |
| 54 |
delete that line from package.env. |
| 55 |
|
| 56 |
It works here for a quick: |
| 57 |
|
| 58 |
==== |
| 59 |

HTH, |

-dnh, tending to be very pragmatic in cases like this ;) |
