Multiple lazarus found error... lazarus / 1-Linux ---------------------------------------------------------------------- Mark- · 2018-09-23 01:35 Hello, Thought I removed everything fpc/lazarus related before installing 1.8.4. The attached error appears when starting Lazarus. Searching for the custom executable, no joy. Where could it be? Thanks, Mark ---------------------------------------------------------------------- Handoko · 2018-09-23 02:01 You need to do a total removal before reinstall the Lazarus/FPC: 01. Uninstall lazarus, fpc, fpc-src 02. Delete ~/.lazarus, except: editoroptions, environmentoptions 03. Delete /etc/fppkg (folder) 04. Delete /etc/fp.* 05. Delete /usr/share/fpcsrc (folder) 06. Delete /usr/lib/fpc (folder) 07. Delete /usr/bin/ppc* Note: I keep those 2 files in step #2 because I want to keep some setttings I configured for Lazarus. You can delete them if you want. ---------------------------------------------------------------------- Mark- · 2018-09-23 02:13 Thanks for the response. I just did a complete reinstall and want to avoid it for now. Do you know where Lazarus is getting that path from? It is an actual file, a line in a configuration file, etc? ---------------------------------------------------------------------- lucamar · 2018-09-23 02:24 Just to be certain: ~/.lazarus is a hidden directory (note the starting dot); are you sure you looked there? That second (rather first) Lazarus is a rebuilt IDE, probably because you (un)installed some packages in the old installation.

It is an actual file, a line in a configuration file, etc? startlazarus looks in that path precisely because it knows that a "extended" Lazarus  is built there. The problem arises because its date is actually older than the supposed "original", so it thinks (quite logically) that you have two different Lazarus versions. ---------------------------------------------------------------------- Mark- · 2018-09-23 02:56 Thanks lucamar, that solved it. When I read your signature I had a nice chuckle. Recalled sitting at a desk working on Z80 with CP/M on 8 inch floppy disk.
