2 years ago first of all you are using Qt5 (qmake defaults now to qmake-qt5), lfhex was written for Qt4 and I am not sure it works without errors in Qt5
for the being use https://github.com/srtlg/archlinux-packages/tree/master/lfhex as I am not the maintainer of lfhex on AUR
for Qt5 use something like
cd src
qmake-qt5
sed -e '/expr\.tab\.h/ s:.(MOVE) :cp -p :g' -i 'Makefile'
make -j`nproc`and let me know, if it works as expected on Qt5

2 years ago Compiles and works perfectly fine with qt5. I think you could update the README.install to include build instructions for both Qt4 and Qt5:
# qt5 log
$ wget https://github.com/srtlg/lfhex/archive/refs/tags/v0.43.tar.gz
$ tar zxvf v0.43.tar.gz

for the being use https://github.com/srtlg/archlinux-packages/tree/master/lfhex as I am not the maintainer of lfhex on AUR
Also there isn't the lfhex deb package for latest Ubuntu 21.04.1. The latest version is lfhex (0.42-3.1build1) for bionic (18.04LTS) which is also dependant on Qt4 and requires to add third party repos to install such libraries. Anyway doesn't work they are broken.

2 years ago Also I would recommend creating 2 AUR pacakges, one for lfhex-qt4 and another for lfhex which would use qt5. So anybody can download lfhex v0.43 with either library. I don't think much people still uses Qt3.

2 years ago I've contacted the maintainer of lfhex, he will probably respond at some time. Qt4 is obsolete. Amazing that it even compiles with GCC 12
