Compilation issues

[el-damiano]

Hello.
I love your software and was using it previously on my Ubuntu 20.04 LTS installation from the Win10 Store.
However recently I had to reinstall Ubuntu and I'm encountering issues when doing cmake.

This is what I get after typing cmake .

  the cmake_policy command to set the policy and suppress this warning.

This warning is for project developers.  Use -Wno-dev to suppress it.

-- Could NOT find Qt3 (missing: QT_QT_LIBRARY QT_INCLUDE_DIR QT_MOC_EXECUTABLE)

I wanted to see if I can just ignore those errors and went ahead and wrote

make -j

and I got this

But in the end I was unable to invoke it. Tried with "mcmap" ".mcmap" and how I used to do it "./mcmap"

I tried installing GTest and QT, but I ended up with more issues than before and it felt quite time consuming. On top of that I didn't have to do that the last time I used your software so I decided to ask you for help.

Hello,

I am glad you are liking the program ! You must have had an ancient version if you used ./mcmap. I changed a bunch of things, and to clean things up, I moved the binary to the bin directory.

I take it you are from the Windows ecosystem. On the command line, you can run custom commands by writing their 'path': the list of directories/sub-directory/sub-subdirectory.. to arrive to the binary. What you did when writing ./mcmap was telling the computer "I want the mcmap binary to run from here (which is . in OS language)".

Now as I moved all binaries to ./bin, you just have to run ./bin/mcmap instead. I am sorry for the trouble it created, but I switched to a more reliable build system and this was the cleanest thing to do.

Thank you kindly for the quick reply!

And yeah you were right my version was ancient lol the current one runs so much faster.
Well with this I'll close this thread thanks a lot again.

Have a good one!
