Description PhobosK 2019-05-06 21:43:03 UTC
Created attachment 575438 [details, diff]

The new sci-libs/proj-6.0.0 is preparing for v. 7.0.0 where the usage of proj_api.h will be deprecated, so now at version 6.0.0 an error occurs when trying to use it.
Packages must be updated properly upstream, but till that happens a way to fix this is to append the necessary flags.

The sci-geosciences/merkaartor-0.18.3-r4 package gives the error too:
In file included from common/Projection.h:12:0,
                 from common/MapView.h:4,
                 from Features/Feature.h:8,
                 from Features/Features.h:2,
                 from Backend/MemoryBackend.h:4,
                 from common/Global.h:19,
                 from common/Global.cpp:13:
/usr/include/proj_api.h:37:2: error: #error 'To use the proj_api.h you must define the macro ACCEPT_USE_OF_DEPRECATED_PROJ_API_H'
 #error 'To use the proj_api.h you must define the macro ACCEPT_USE_OF_DEPRECATED_PROJ_API_H'

I am uploading a proposed fix for the ebuild tested to be working OK ...

Comment 3 Andreas Sturmlechner gentoo-dev 2020-06-22 08:38:23 UTC
Re-opening as a workaround is no fix and it is running out of time.
Comment 4 Andrius Štikonas 2021-04-10 10:33:42 UTC
The following patch
seems to help with this, although, I couldn't build merkaartor successfully even with it due to unrelated problem:

GPS/qgpsdevice.cpp: In member function ‘virtual void QGPSDDevice::onDataAvailable()’:
GPS/qgpsdevice.cpp:1055:22: error: could not convert ‘((QGPSDDevice*)this)->QGPSDDevice::gpsdata->gps_data_t::fix.gps_fix_t::time’ from ‘timespec_t’ {aka ‘timespec’} to ‘bool’
 1055 |     if (gpsdata->fix.time)
      |         ~~~~~~~~~~~~~^~~~
      |                      |
      |                      timespec_t {aka timespec}
GPS/qgpsdevice.cpp:1056:63: error: no matching function for call to ‘QDateTime::fromTime_t(timespec_t&)’
 1056 |         cur_datetime = QDateTime::fromTime_t(gpsdata->fix.time);
      |                                                               ^

Presumably it is only a problem with USE=gps
