I can not install OMNET++ to my m1 Mac because configure
script can't install qt libraries.
I get this classic error:
configure: error: Cannot build Qt apps, probably due to missing or too old Qt packages. Make sure Qt development packages are installed and newer than Qt 5.4. You can disable Qtenv by setting the WITH_QTENV variable to "no" in configure.user.
Normally OMNET++ comes with its own QT5 libs bundled with it but for some reason it can not detect these libraries.
So I tried:
brew install qt
and adding it to pathsource setenv
from zsh then ./configure
. setenv
from bash then ./configure
These didn't work so, I inspected config.log
for further details. Which showed
ld: library not found for -lQt5Gui
Then I changed the line with code in configure
script, which in at line 4721
QT_LIBS=${QT_LIBS:-"-lQt5Gui -lQt5Core -lQt5Widgets -lQt5PrintSupport -lQt5OpenGL $LDFLAG_LIBPATH$QT_INSTALL_LIBS -Wl,-rpath=$QT_INSTALL_LIBS"}
To this, by only changing the first lib.
QT_LIBS=${QT_LIBS:-"-L/opt/homebrew/Cellar/qt/5.15.2/lib -lQt5Core -lQt5Widgets -lQt5PrintSupport -lQt5OpenGL $LDFLAG_LIBPATH$QT_INSTALL_LIBS -Wl,-rpath=$QT_INSTALL_LIBS"}
Then it gave similar errors for Qt5Core
Qt5Widgets
Qt5PrintSupport
Qt5OpenGL
so I removed them and added frameworks folder. Finally I achieved this:
QT_LIBS=${QT_LIBS:-"-L/opt/homebrew/Cellar/qt/5.15.2/lib -L/opt/homebrew/Cellar/qt/5.15.2/Frameworks $LDFLAG_LIBPATH$QT_INSTALL_LIBS -Wl, -rpath=$QT_INSTALL_LIBS"}
Still gives me the same error. I am stuck.
For the moment, you should run omnet in x86 emulation mode. Start a shell window with:
arch -x86_64 /bin/zsh --login
And then configure and build OMNeT++ from there. You must run EVERYTHING from that shell.
