Rebuild Lazarus with qt and "can't call the resource compiler"
« on: December 02, 2020, 02:50:32 pm »
Hi
I'm trying to rebuild lazarus with qt (I need it for FastReport) and get the following error:
lazarus.pp(165,1) Error: Can't call the resource compiler "/root/fpcupdeluxe/fpc/bin/x86_64-linux/fpcres", switching to external mode.

Lazarus 2.0.1, FPC 3.2.0 (build from fpcupdeluxe)
Centos 7 on VirtualBox, qt package installed, memory:

[root@localhost ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:     1838         493        1042           7         301        1150
Swap:     1283         305         978

Any ideas?
Regards

Permissions, apparmor etc.

And also running out of RAM memory can cause this error. You need much RAM to compile Lazarus. Most often, this error occurs on RPI's.

@marcov
It's vanilla Centos 7 VM - for lazarus only. No apparmor. Build/rebuild with root acount, fpcres owned by root:root 755 (just like any other bin's).

@DonAlfredo
I saw posts related with memory issues, that's why I've pasted free -m output. Do you think it may be not enough?

To be honest: that should be enough. Building as root is something I have never done, but that should not be a problem I guess.

Not a problem that I've seen on Debian. The one thing that I'd add though is that while I move most FPC utilities off the path, the three that /do/ have to be on the path are fpc, ppcXXX and fpcres.

I got into deep water a couple of weeks ago when it turned out that my fpc binary was accidentally 32-bit with everything else 64-bit, and one of the things that that affected was Qt. However that was Lazarus trunk + 3.2.0, and I had to back off that combination for some other reason that escapes me.

Plz report back when you remember: I have no issues at all with 3.2.0+

I've added to path whole /root/fpcupdeluxe/fpc/bin/x86_64-linux - not helped.

Hi,

you don't mention a qt version. Because there is CentOS 7, it's should be qt 4.

I have worked Lazarus installation qt4 rebuilded. Lazarus was downloaded from official web site. I installed libqt4pas, I think from Fedora repository and some addition qt4 package from repository. Rebuilded Lazarus for qt4 widget set under root.
Lazarus 2.0.6 - CentOS 7.x, Mageia 7.1

@mig-31 Good point. In my case I'm on Debian "Buster" but had to get libqt4pas from the preceding release.

Just for the record - after many tries of rebuilding IDE with different configurations lazarus died - stopped launch at all.
In the meantime it turned out, that new FastReport uses gtk2, so I don't need qt.
I've built brand new VM, Centos 8 with 4GB RAM, new Lazarus+FPC from fpcupdeluxe and FastReport was successfully installed.

It's good to hear that you've had some level of success, but this whole business is still unfortunate.
