I’m trying to install Unikey (a program for typing Vietnamese) on Ubuntu 22.04 by following the instructions on the Unikey Linux page. While running ./configure was successful, I encountered an error during the make step.
The output of ./configure is extensive, but it completed without any errors. However, running make resulted in the following errors. It appears that there are issues related to “narrowing conversion” in data.cpp:

From what I understand, it seems I have to modify the source code to resolve these issues. However, I would prefer not to do this if possible. I suspect the problem might be related to the GCC or G++ version. Here is the output from gcc --version and g++ --version:

I followed the instructions on the Unikey Linux page and ran ./configure, which completed without errors. During the make step, I encountered “narrowing conversion” errors. I then tried using the command make CXXFLAGS="-Wno-narrowing", but it resulted in additional errors. I expected the compilation to complete successfully without modifying the source code, but the process failed due to conversion and compatibility issues.
