Error on geotiff coordinate transformation - c++

Question

Have error and crash in an application using GDAL for extracting latitude & longitude from GeoTiff image running it in openSUSE, while it works fine in Ubuntu for my colleagues. Errors are different for gdal-v3 and gdal-v2 versions, however seems problem is in OGRCreateCoordinateTransformation object creation: returns NULL in both cases. See details below:
Code:
QGeoCoordinate toGeoCoordinate(double* adGeotransform, OGRSpatialReference& srcRef, int x, int y)
{
double worldX = adGeotransform[0] + x * adGeotransform[1] + y * adGeotransform[2];
double worldY = adGeotransform[3] + x * adGeotransform[4] + y * adGeotransform[5];
OGRSpatialReference dstRef;
dstRef.importFromEPSG(4326);
QScopedPointer<OGRCoordinateTransformation> coordinateTransform(
OGRCreateCoordinateTransformation(&srcRef, &dstRef));
coordinateTransform->Transform(1, &worldX, &worldY);
return QGeoCoordinate(worldY, // lat
worldX); // lon
}
QGeoRectangle extractCoordinate(const QString& path)
{
GDALAllRegister();
GDALDataset *poDataset = (GDALDataset *) GDALOpen( path.toStdString().c_str(), GA_ReadOnly );
_height = GDALGetRasterYSize(poDataset);
_width = GDALGetRasterXSize(poDataset);
double adGeotransform[6];
poDataset->GetGeoTransform(adGeotransform);
OGRSpatialReference srcRef(poDataset->GetProjectionRef());
QGeoCoordinate _topLeft = toGeoCoordinate(adGeotransform, srcRef, 0, 0);
QGeoCoordinate _bottomRight = toGeoCoordinate(adGeotransform, srcRef, _width, _height);
return QGeoRectangle(_topLeft, _bottomRight);
}

ERROR 6: Unable to load PROJ.4 library (libproj.so.15), creation of OGRCoordinateTransformation failed.
Ubuntu 18.03 LTS (works fine):
libgdal - 2.2.3
libgeotiff - 1.4.2
libproj12 - 4.9.3
So asking for possible solutions:
What the errors cause could be:
wrong libraries versions;
wrong build flags on openSUSE?
GeoTiff could be extracted other way?

Answer 1

Problem is in PROJ library version used. For GDAL v2 need to use libproj v6. However required libgeotiff5 and libspatialite built against libproj19 (proj v7) in openSUSE Tumbleweed. So need to
Uninstall all recent versions of: libspatialite, geotiff, libproj19, gdal.
Install libproj15 for example from this repo home:rogeroberholtzer
Rebuild libspatialite & geotiff libraries from src.rpm against this installed libproj15 ourselves:
rpmbuild --rebuild --clean libspatialite-4.3.0a-15.19.src.rpm
rpmbuild --rebuild --clean geotiff-1.5.1-31.13.src.rpm
These packages could be taken from science repo for example.
Install built packages: rpm -Uvh *
Install gdal2-2.4.2 rpm from science repo.
And all works! Enjoy! :)
