Is libgd.so.3 backward compatible with libgd.so.2

[caldodge]

We are installing an older application on a Red Hat 8.3 system, which comes with libgd.so.3. The application wants libgd.so.2.

Will this work if we symlink libgd.so.2 to libgd.so.3? Or do we have to find a libgd.so.2 library that's compatible with Red Hat 8.3?

if it were compatible, we'd use the same name. you should not symlink.

Vapier, thanks for your quick response. It appears I will need to build it from source. What is the latest version of GD which provides libgd.so.2?

The soname was bumped from 2 to 3 in 0199503 so you'd probably want a libgd prior to 2.1.0. e.g. https://github.com/libgd/libgd/releases/tag/GD_2_0_33 This is very very old, so it may not build on a modern system, any definitely has security problems you might need to be aware of.

Bathterror,

Thanks for your reply. The cluster is relatively isolated, so security isn't a major concren. We ended up grabbing the file from a Centos 6.10 rpm.
