"Bus error (core dumped)" when drag&dropping an image (Kubuntu 19.04, Konsole) #9

Closed MarshmelloSUCKS closed 5 years ago

I tried dragging a 200kb JPG file into TermColor and it crashed. Here's what it says:


Bus error (core dumped)```
What can I do? Running Kubuntu 19.04, Konsole terminal.

@MarshmelloSUCKS So yeah, I've managed to reproduce the issue. The issue is with the g++'s packages it depends on version mismatch -- to build TermColor, you need the g++ (the C++ compiler) to support the features of C++17. Directly installing g++ on Ubuntu 19.04 installs a meta-package g++-8, which is an older version, and you need g++-9.

So here's a workaround. Assuming you followed the instructions step by step, you probably have installed the g++ package. Running apt list --installed | grep g++ would yield the following:

g++-8/disco,now 8.3.0-6ubuntu1 amd64 [installed,automatic]
g++/disco,now 4:8.3.0-1ubuntu3 amd64 [installed]

So, remove g++ and its meta-packages:

sudo apt remove g++ g++-8
sudo apt autoremove # (to remove `libstdc++-8-dev`)

Obtain g++-9, and gcc-9 (the C compiler). Then update the compiler linking:

sudo apt install g++-9 gcc-9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 20 --slave /usr/bin/g++ g++ /usr/bin/g++-9

Now running g++ --version or gcc --version will tell you that both g++ and gcc are version 9.1.0. The project should build successfully now.

I should probably update the README with building instructions for different Linux distributions.
