[fpc-devel] Error building FPC main in Fedora 44 ("read-only segment has dynamic relocations", in linking pas2js)

[Flávio Etrusco]

Hi all,

Is this a known bug? Any directions to investigate this?

Free Pascal Compiler version 3.2.2 [2021/05/16] for x86_64 (downloaded
from SourceForge, IIRC)
Output:
(...)

Should pas2js not be compiled with -Cg? Is my system.o not compiled
with -Cg/$PIC? Is some code writing to "writable consts" and
shouldn't?
Thanks in advance.
