The Lazarus team is glad to announce the third release candidate of Lazarus 4.0.

The title doesn't say "third release".   Is it really the "third release candidate" or is this the final release ?

the 64-bit x86 ELF binaries for linux appear to be broken due to bad symbol versioning:

this should be fixable by running sudo make bigide from within the 4.0.0 directory, preferably directly after installation.


cheers,

What linux distro is this?

[dbannon]

What linux distro is this?

Any distro running libc 2.34 or earlier. Sadly lots of still 'supported' ones.

Davo

[440bx]

Fixed

Thank you.  that was confusing.

and a big thank you to every member of the Lazarus team who made v4.0 possible.

[mattias]

Where is libc 2.34 still supported?

[zeljko]

That binaries are built on distro with 2.34, that's all. Lazarus binaries (not distro ones) should be built on older distro, with compatibile glibc, eg on Ubuntu 20.
