Hi all,

Just upgraded to the AMD 64 versions of FPC 3.02 and Lazarus 1.6.4 as downloaded from SourceForge, I upgraded an instance of 1.6.2 (from the same source) which was working just fine. I'm running 64-bit Linux Mint 'Betsy', i.e. the Debian-based version of Mint, on a AMD Phenom x2. The problem is that rebuilding the IDE doesn't seem to work.

The error is shown as 'Generic error while linking'. I don't think the source line is relevant, as it tags the 'end.' in lazarus.pp. The exit code returned is 512.

Any ideas, please?

Thanks,

Brian.

P.S. Same error when trying to build a 'Hello, World' simple program.

I built on amd64 using pukka Debian a couple of days ago with no problems. GNU ld (GNU Binutils for Debian) 2.25

The version of binutils in the LMDE repositories is 2.25-5. I did do an apt-get update, upgrade and -f install before posting. Everything was up to date.

Right click on the messages window, copy -> copy all/original messages to clipboard
Then open a text editor and paste what you just copied, so you can see the exact linker error.

Bye

Thank you, that found more details of the problem, but I'm still at a loss how to fix it. I think this is the relevant section of the messages...

I don't know how to fix it either, but try searching google for the message "unrecognized relocation (0x2a)": there are a couple of bug reports against ubuntu and debian and maybe they apply to your distribution.

The bug reports are against the version of libc6 (2.21) found in Debian testing. Mint Debian uses Jessie, aka stable, and my libc6 is definitely not the version which is supposed to exhibit the bug.

Mark, could you please check your version of libc6?

Thanks.

Like this?

$ sudo ldconfig -v |grep libc
..
libc.so.6 -> libc-2.19.so

ar, as and ld .

$ uname -a
Linux pye-dev-04 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1 (2016-12-30) x86_64 GNU/Linux

That should be an ablutions-standard Debian "Jessie". In the interest of full disclosure it's had deb-multimedia enabled to install something like Flash at some point, but apart from that I'd expect no surprises.

Thanks. The bug reports I read (pointed to by Luca) suggested that it was the version of libc6 on the system which indicated the problem would occur, but the suggestion was that it has to be the version in testing (2.21, I think). You have exactly the same version as I do, which is what I would expect, LMDE is explicitly said to be based on Jessie. I think it's time to put a vanilla Jessie in a VM and set up Lazarus and FPC in that (takes a day or so thanks to this @#$%^*& satellite internet!) - unless someone else surprises me and comes up with a fix. I recall it being some kind of problem with a much earlier version of LMDE and Lazarus/FPC which drove me from Mint to Debian in the first place. I don't know how they do it... :(

Brian.

Well, the problem appears to be with FPC 3.0.2. Writing just a simple 'Hello World' using the FP IDE exhibits the same problem. Downgrading to FP 3.0.0 and Lazarus 1.6.2-1 means everything is back to normal. I guess I'd better head over to the Pascal group and post details there, unless somebody has beaten me to it.

Brian.
