Colmap does not find libceres at runtime????

[christo...@gmail.com]

I sucessfully built Colmap on my system but when I want to start Colmat the following error message comes up.

What to do ?

christoph@celsus:~/software/colmap/build$ /usr/local/bin/colmap

/usr/local/bin/colmap: error while loading shared libraries: libceres.so.1: cannot open shared object file: No such file or directory

code here...

But it compiled sucessfully before with the following seetings

-- Boost version: 1.62.0

--   program_options

Has anyone an idea why this can happen? ceres of course is installed and libceres.so.1 can be found in /usr/local/lib !

Thanks in advance christoph

Hi,

Is /usr/local/lib in your LD_LIBRARY_PATH? Otherwise, I suggest to link the static version of Ceres Solver into COLMAP.

Best,
Johannes

Thank you for your reply I solved the issue by making a symbolic link to  /usr/lib/libceres.so.1 and colmap starts jipee... that was hard ... but  finally got it to work. I needed to update to cuda 9 cause apparently I compiled cuda 8 with gcc 4.9 and colmap didn't like it to much as debian 9 uses gcc 6.  But now finally all good! Thank you a lot for your effort. 

That seems to be a bug cause /usr/local/lib is in already in LD_LIBRARY_PATH. All my other compiled sofware workes nice and smooth. No complains :-).
