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?

QuoteDo 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.

@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.
