I had no problem compiling and installing libtiff 3.7.1, but I find it odd that I now have:

 -rw-r--r--   1 root sys   375670 Jan 14 13:12 /usr/local/lib/libtiff.a
 -rwxr-xr-x   1 root sys      847 Jan 14 13:12 /usr/local/lib/libtiff.la
 -rwxr-xr-x   1 root sys   443852 Jan 14 13:12 /usr/local/lib/libtiff.so@
 -rwxr-xr-x   1 root sys   443852 Jan 14 13:12 /usr/local/lib/libtiff.so.10.7.1
 -rwxr-xr-x   1 root sys   443852 Jan 14 13:12 /usr/local/lib/libtiff.so.3@

Whence that "10.7.1"? I do see that all the Makefiles contain:

 LIBTIFF_MAJOR_VERSION = 3
 LIBTIFF_MICRO_VERSION = 1
 LIBTIFF_MINOR_VERSION = 7

Jean-Pierre,

There are two sets of version information for libtiff. The public release numbers (like 3.7.1) and the internal libtool/so release numbers derived by a different mechanism which now appears to be set at 10.7.1.

If you read up on libtool you can find some info, but basically accept that the internal numbers are not very directly meaningful.

Best regards,
