<b​4n6_b4n6:matrix.org> monero-project/monero-gui #4346

any idea why it builds with `CMAKE_PREFIX_PATH=$HOME/Qt/5.15.2/gcc_64 make` just fine but in QtCreator it fails on: [315/511]: FAILED: monero/contrib/epee/src/libepee_readline.so

. /usr/bin/ld: monero/contrib/epee/src/CMakeFiles/obj_epee_readline.dir/readline_buffer.cpp.o: in function `handle_line(char*)':/projects/monero-gui/monero/contrib/epee/src/readline_buffer.cpp:177:(.text+0x8d2): undefined reference to`epee::string_tools::trim_right(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&)' collect2: error: ld returned 1 exit status

<r​brunner7:monero.social> vthor: I think the cause is the problem solved in this PR. It's already merged on master, but maybe the code that you use does not yet have it? monero-project/monero #9342

vthor: Hi! I'm going to upgrade to Qt6 this weekend and send a pull request maybe next week. We can try to do that together if you like.

rbunner7: thank you, will double check now, I did simply `git pull && git submodules update` and assumed with that all is up to date in master.

aperechnev: '_tobtoht: "I imagine it will not much tu upgrade to 6.8.x " <- The build system work alone is probably a few weeks of works.' I appreciate the offer very much and if I could afford I would love to do (although I think I would not be of great help) to learn more about the build system. But unfortunately I can't go any additional rabbit holes at the moment, and need to pass on this one for this time.

rbunner7: git status: HEAD detached at b089f9ee6, and in git log I can see the last commit b089f9ee69924882c5d14dd1a6991deb05d9d1cd was from Aug 14, where #9342 was merged Jul 16, was about to write to days berfore but actually was one month before. In git logs I can't fing the merge #9342, so I looked into the changes and then into the file contrib/epee/src/readline_buffer.cpp and there it doesn't seem that the changes are applied.

<r​brunner7:monero.social> vthor: That's the Monero code within the GUI repo, right? I never really got to the bottom of that, "detached HEAD" and all, my git fu is not strong enough. Not sure, maybe you have to cherry-pick that PR yourself into that Monero code for the time being?

I will check first going on head of master, but I wonder how the build works without issues in the terminal, but not in the IDE. Hehe, I think my git fu is very probable worse, I never used it to colaborate with anybody, and still every week I have and 'aha'(so easy :S ) - effect with it, but I will figure it out. Thank you for your time! :)
