[GRASS-dev] libLAS on Ubuntu 14.04

[Yann Chemin]

I can confirm the issue,

also by trying these configure options it is not helping:
--with-liblas --with-liblas-config
--with-liblas --with-liblas-config=/usr/bin/liblas-config
--with-liblas=yes --with-liblas-config
--with-liblas=yes --with-liblas-config=/usr/bin/liblas-config

Also two targets are found, both valid (v1.7.0) and identical:
whereis liblas-config
liblas-config: /usr/bin/liblas-config /usr/bin/X11/liblas-config
/usr/share/man/man1/liblas-config.1.gz

$ ls -aslh /usr/bin/X11/liblas-config
4.0K -rwxr-xr-x 1 root root 2.5K Feb 26 14:43 /usr/bin/X11/liblas-config
$ ls -aslh /usr/bin/liblas-config
4.0K -rwxr-xr-x 1 root root 2.5K Feb 26 14:43 /usr/bin/liblas-config
