laszip installation in Ubuntu

[Mohammad Asad Riaz]

can any one tell me the proper and easy way to install laszip in ubuntu?

[Jochen Rapidlasso]

Hi  Mohammad,

see at https://rapidlasso.de/lastoollinux-multicore/

there you find ready to use linux binaries. Please use las2las64 to zip LAS files to LAZ format.

Best,

The pre-build X64 binaries offered here have strong dependencies on your C++ and C runtime version:

./lasinfo64: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by ./lasinfo64)

This is difficult to fix, unless you use it in container environment where you can switch to any runtime you need. I’d rather just build the binaries from the sources. I have done that for several Unix/Linux platforms: RHEL7 an RHEL8 on X64, RHEL8 and RHEL9 on ARM64, macOS on X64 (I still need to test with macOS on ARM64). The process is simple and straightforward, like this (for linux)

# Fetch sources

wget https://downloads.rapidlasso.de/LAStools.zip

# Unzip archive

unzip -qf LAStools.zip

# Build: ignore the warnings. Results go into ./LAStools/bin64

cd LAStools

cmake -DCMAKE_BUILD_TYPE=Release .

cmake --build . --target=clean

# Install: link binaries in /usr/bin

for F in ./bin64/* ; do sudo ln -sf $(readlink -e $F) /usr/bin/$(basename ${F:0:-2}) ; done

# Check that everything works

lasinfo ./data/test.laz
