On RH5.1 libpng-1.0.2 is nbecker> called libpng-2.1.0 (I think that was actually my doing when nbecker> I put it into libgr, IIRC). 1.0.2 is binary compatible with what little testing I gave it. There are a couple of new functions/features, but the rest is bugfixes. nbecker> So I'm calling libpng-1.0.2 libpng-3.0.0. What do you think? I don't quite understand where your question comes from... The libpng-1.0.2 makefile should create for you a shared library with the soname of 2.1.0.2. If you look at the top of png.h, you will see the following: * Note about libpng version numbers: * * Due to various miscommunications, unforeseen code incompatibilities * and occasional factors outside the authors' control, version numbering * on the library has not always been consistent and straightforward. * The following table summarizes matters since version 0.89c, which was * the first widely used release: * * source png.h png.h shared-lib * version string int version * ------- ------ ----- ---------- * 0.89c ("1.0 beta 3") 0.89 89 1.0.89 * 0.90 ("1.0 beta 4") 0.90 90 0.90 [should have been 2.0.90] * 0.95 ("1.0 beta 5") 0.95 95 0.95 [should have been 2.0.95] * 0.96 ("1.0 beta 6") 0.96 96 0.96 [should have been 2.0.96] * 0.97b ("1.00.97 beta 7") 1.00.97 97 1.0.1 [should have been 2.0.97] * 0.97c 0.97 97 2.0.97 * 0.98 0.98 98 2.0.98 * 0.99 0.99 98 2.0.99 * 0.99a-m 0.99 99 2.0.99 * 1.00 1.00 100 2.1.0 [int should be 10000] * 1.0.0 1.0.0 100 2.1.0 [int should be 10000] * 1.0.1 1.0.1 10001 2.1.0 * 1.0.1a-e 1.0.1a-e 10002 2.1.0.1a-e * * Henceforth the source version will match the shared-library minor * and patch numbers; the shared-library major version number will be * used for changes in backward compatibility, as it is intended. The * PNG_PNGLIB_VER macro, which is not used within libpng but is available * for applications, is an unsigned integer of the form xyyzz corresponding * to the source version x.y.z (leading zeros in y and z).
