使用LAZperf构建PDAL

Question

我在Ubuntu 18:中以这种方式构建PDAL

cd /home/magno/install && 
git clone https://github.com/hobu/laz-perf.git  && 
cd laz-perf && 
mkdir build && 
cd build && 
cmake .. 
-DEMSCRIPTEN=1 
-DCMAKE_TOOLCHAIN_FILE=/home/magno/install/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake && 
VERBOSE=1 make && 
make install
cd /home/magno/install && 
git clone https://github.com/pgpointcloud/pointcloud && 
cd pointcloud && 
./autogen.sh && 
./configure --with-lazperf=/usr/local/ && 
make && 
make install
cd /home/magno/install && 
git clone https://github.com/PDAL/PDAL.git && 
cd PDAL && 
mkdir build && 
cd build && 
cmake -G Ninja .. && 
ninja && 
ninja install

运行PGUSER=postgres PGPASSWORD=*** PGHOST=localhost PGPORT=5432 ctest可以确认一切正常。

但当我尝试检查LAZ文件时，我会收到以下错误：

PDAL: readers.las: Can't read compressed file without LASzip or LAZperf decompression library.

这是我的管道文件：

{
"pipeline":[
{
"type":"readers.las",
"filename":"airport.laz",
"spatialreference":"EPSG:32616",
"compression":"lazperf"
},
{
"type":"writers.pgpointcloud",
"connection":"dbname=mydb host='localhost' user='postgres' password='****'",
"table":"patchs",
"compression":"lazperf",
"srid":"32616",
"overwrite":"false"
}
]
}

我认为lazperf是可以的，因为pgpointcloud没有抱怨PGUSER=postgres PGPASSWORD=**** PGHOST=localhost make installcheck，并且告诉我：

#  PointCloud is now configured for

#  C compiler:           gcc -g -O2

#  CUnit status:         enabled

PDAL测试告诉我关于压缩的任何信息。

我如何构建或告诉PDAL我的LAZPerf安装？

EDITpdal info install/PDAL/test/data/las/autzen_trim.las完全可以。

上帝保佑谷歌！

通过阅读这个、这个和这个找到了解决方案。

只需更改为cmake -G Ninja -DLazperf_DIR=/usr/local/ -DWITH_LAZPERF=ON ..

瞧：

* Lazperf
* ZSTD
