Hello, after I managed to build cctag (by insertion of "cd" commands into PKGBUILD), now I have problems building alice-vision-git. The problem: Minor versions of OpenEXR (3.0.x) and Imath (3.1.x) differ. To fix the problem, I added "-DOPENEXR_IMATH_LIBRARY=/usr/lib/libImath-3_1.so" to PKGBUILD. This worked in one (or some) case(s), but it does not work for libAlembic: /usr/bin/ld: warning: libImath-3_0.so.28, needed by /usr/lib/libAlembic.so.1.8, not found (try using -rpath or -rpath-link) /usr/bin/ld: /usr/lib/libAlembic.so.1.8: undefined reference to `Imath_3_0::half::convert(int)' /usr/bin/ld: /usr/lib/libAlembic.so.1.8: undefined reference to `Imath_3_0::half::_eLut' /usr/bin/ld: /usr/lib/libAlembic.so.1.8: undefined reference to `Imath_3_0::half::_toFloat' /usr/bin/ld: Linux-x86_64/libaliceVision_sfmDataIO.so.2.4: undefined reference to `Alembic::AbcGeom::v12::XformSample::setMatrix(Imath_3_1::Matrix44<double> const&)' It seems, QmlAlembic does not honour the config option "OPENEXR_IMATH_LIBRARY". Kind regards, Peter
