Can't configure on ubuntu 18.04 LTS

[Phoveran]

checking dynamic linker characteristics... (cached) GNU/Linux ld.so checking how to hardcode library paths into programs... immediate checking for X... libraries , headers checking for gethostbyname... yes checking for connect... yes checking for remove... yes checking for shmat... yes checking for IceConnectionNumber in -lICE... no configure: error: Qt >= 4.6.0 is required. configure: error: ./configure failed for qucs

Keeps telling me this..... However I checked that I have Qt 5.9.5 installed. How to solve this?

[guitorri]

Qt5 is not yet supported.

[Phoveran]

Qt5 is not yet supported.

Well...I tried Qt 4.8.7, not good as well~~

What is the problem exactly? I am using it on 18.04 lts as well, no problems here...

I downloaded qucs from Sourceforge, unzipped it and did ./configure , Then it tells me I have to install Qt >= 4.6.0. However I have Qt 4.8.7 installed.

Is there any known fix for that? i cannot install it on my Ubuntu 18.04.2 LTS as well.

I just now pulled the "develop" branch on git, and on my system (18.04 up-to-date) it configures ok. Compiling now.

Could you please report the exact error you have?

Actually I can't figure out what your 'exact error' means... I just ran the configure file and it threw an error telling me that It needs Qt >= 4.6.0.

[in3otd]

can you post the content of the file qucs/config.log (not the top-level config.log) and the output of pkg-config --list-all | grep -i qt

here is the file: config.log

and there is no output of that command

[in3otd]

but it's strange that pkg-config did not return anything about which Qt stuff is installed. configure uses pkg-config to know where the Qt stuff is located so if that does not work it will not be able to find any Qt.

So I used sudo apt install qt4-default to install qt4.8.7. Is the problem coming from here?

[Rmano]

I did use the commands as in the main README of the project:

sudo apt-get install build-essential
sudo apt-get install libqt4-dev libqt4-qt3support
sudo apt-get install automake libtool libtool-bin gperf flex bison

...and it worked.

[rjordans]

I just did a successful build on 18.04 here as well. Is this still a problem?
