Re: qt-gui problems with GNU 3.8

[CEL]

Ah, it's the same old blues; need to have qt(4)-devel packaged for qwt.

(What I've tried is: Run Fedora as host, and have a podman (or docker,
as if I care, replace "podman" by "docker" below) container

marcus@workstation> podman run -it --rm centos:8)

This is a very rough rundown of what I just did in a fresh CentOS 8
container:

[root@hash /]# dnf check-update; dnf install -y epel-release
[root@hash /]# dnf update -y
[root@hash /]# dnf install -y make rpm-build qt5-qt*-devel rpmdevtools
ccache
[root@hash /]# adduser mockbuild
[root@hash /]# cd
[root@hash ~]# curl -o qwt-6.1.3-11.fc31.src.rpm 
https://ftp-stud.hs-esslingen.de/pub/fedora/linux/releases/31/Everything/source/tree/Packages/q/qwt-6.1.3-11.fc31.src.rpm
[root@hash ~]# rpm -i qwt-6.1.3-11.fc31.src.rpm

I had to hunt down a lot of qt4 lines in the qwt.spec and remove them
before this builds on CentOS 8. I have just attached a diff for a
successfully building Qwt6 on the Bug that Vasil mentioned [2], so we
can try that one; continue with

[root@hash ~]# cd rpmbuild/SPECS
[root@hash SPECS]# rm qwt.spec
[root@hash SPECS]# curl -o qwt.spec 
https://bugzilla.redhat.com/attachment.cgi?id=1636615
[root@hash SPECS]# rpmbuild -bs qwt.spec
[root@hash SPECS]# cd ../SRPMS
[root@hash SRPMS]# rpmbuild -rb *.src.rpm
… waaaait …

This should, if the build succeeds (mine is still running), give you
qwt6-qt5 packages. Install these! 

[root@hash SRPMS]# cd ../RPMS/
[root@hash RPMS]# ls */*
noarch/qwt-doc-6.1.3-11.el8.noarch.rpm
x86_64/qwt-qt5-6.1.3-11.el8.x86_64.rpm
x86_64/qwt-qt5-devel-6.1.3-11.el8.x86_64.rpm
x86_64/qwt-debugsource-6.1.3-11.el8.x86_64.rpm
x86_64/qwt-qt5-debuginfo-6.1.3-11.el8.x86_64.rpm
[root@hash RPMS]# cd x86_64
[root@hash x86_64]# dnf install -y *

Try to build GNU Radio now!


Best regards,
