The following problem occurs when installing the distribution v3.0rc1. What else needs to be added relative to the installation process in install.md?

Looks like I forgot to include the PDFio submodule sources in the tarball. I will be issuing a new 3.0rc2 later today to fix this.

This seems to be a problem. When making

This is a bogus GCC warning. Would be useful to know what OS/Linux distro you are using along with the version of compiler.

[fushengss]

My system is Ubuntu Desktop 22.04.3

Do you need any other relevant information?

[michaelrsweet]

No that’s enough - the version of GCC provided with Ubuntu 22.04 produces these warnings, but the can be safely ignored.

[fushengss]

Could you please provide me a copy of install.md for ubuntu22.04? Thanks a lot
