docker mpc-merge-all failed, PotreeConverter: undefined symbol: laszip_create

[aleksandrmelnyk]

hi all,
tried tocker version of the utility, untill merge all steps ran ok, but tile merging failed with following exception:

READING:  tile_0_2/e2075n70670_1.laz
PotreeConverter: symbol lookup error: PotreeConverter: undefined symbol: laszip_create

Seems like broken (absent laszip dependencies) docker container?

thanks,

Alex.

Edit the Dockerfile like this:

...
RUN wget https://github.com/LASzip/LASzip/releases/download/3.4.1/laszip-src-3.4.1.tar.gz
RUN tar xvfz laszip-src-3.4.1.tar.gz
WORKDIR /opt/laszip-src-3.4.1
RUN mkdir makefiles
WORKDIR /opt/laszip-src-3.4.1/makefiles/
...

instead of:

...
RUN wget http://download.osgeo.org/laszip/laszip-2.1.0.tar.gz
RUN tar xvfz laszip-2.1.0.tar.gz
WORKDIR /opt/laszip-2.1.0
RUN mkdir makefiles
WORKDIR /opt/laszip-2.1.0/makefiles/
...

It worked for me.
