gcc--7.3

[Andrew Bell]

PDAL requires a compiler that supports C++17 completely, including std::filesystem. gcc 7.3 does not support std::filesystem.

这也跟gcc有关系吗？

[Andrew Bell]

I believe you have an old version of libgeotiff. This usually comes with GDAL and the version is checked, so I'm not sure what's going on. Perhaps a version of geotiff is being found that we're not expecting or we haven't properly specified the geotiff version in the build process.

(The value of LIBGEOTIFF_WARNING is 0, so you can just use that instead of you want.)

我换了1.7.1的版本OK了
