Building on Linux

[Neil Woodhouse]

Hey,

   I am one of those weird guys that does not use Windows at all and I wanted to build LASTools on Linux to be specific Ubuntu. I downloaded LAStools.zip and built it. I will say at the start it did get to the end, but there were lots of warnings and the final results mixed in the bin file with all of the windows executables. So my question why is this such a mess? With all of the warnings can I have confidence that the code will work? It would be nice if a test suite could be run after a build for validation.

  Here is a snippet at the end of the make process:

../LASlib/inc/lasdefinitions.hpp: In member function ‘void LASvlr_wave_packet_descr::setDigitizerOffset(F64)’:

../LASlib/inc/lasdefinitions.hpp:1152:68: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]

   inline void setDigitizerOffset(F64 offset) {((F64*)&(data[18]))[0] = offset;};

                                                                    ^

lasindex.cpp: In function ‘int main(int, char**)’:

lasindex.cpp:114:10: warning: variable ‘start_time’ set but not used [-Wunused-but-set-variable]

   double start_time = 0;

          ^

lasindex.cpp:125:71: warning: ignoring return value of ‘char* fgets(char*, int, FILE*)’, declared with attribute warn_unused_result [-Wunused-result]

     fprintf(stderr,"enter input file: "); fgets(file_name, 256, stdin);

Compiling is full of "warnings". A majority of the time, they are safe to ignore.

Errors are what you got to look out for =) That's when the compilation actually fails.

So if you're compilation from source actually finished without errors, you should be good to go.

You can always test out the resulting lastool binaries (on Windows they're called executables) to see if they work when the compilation finishes too.

They can be tested from the source directory before you even run `make install` or whatever you're using to compile and install your packages.

Hello Neil,

I always do a quick test compile on the one linux box that I have access to before I upload a new version. I agree that some simple testing of lasinfo, las2las, lasmerge, lasprecision, txt2las, las2txt, and laszip on the data in the lastools/data example folders would be a nice option to have. Maybe you can add a small patch to the Makefiles to do this that can be started via 'make unit' and contribute it back ... ?

See my compile below ...

Hello,

as I am using Ubuntu as my main OS during work, I am highly interested in running LAStools natively on it. At the moment I have it running in a virtual win7 box. 

I have no real compiling experience, so if anybody could provide a short tutorial/hints (if it could be even described in a "short" tutorial ;) ) how that would work, I would be very thankful.

Andreas
