Getting this error-

[ 97%] Linking CXX executable openttd
/usr/bin/ld: CMakeFiles/openttd_lib.dir/src/survey.cpp.o: undefined reference to symbol 'u_versionToString_76'
/usr/bin/ld: /usr/lib64/libicuuc.so.76: error adding symbols: DSO missing from command line

make[1]: *** [CMakeFiles/Makefile2:2476: CMakeFiles/openttd.dir/all] Error 2

I have no idea what it means or how to fix.

Try to add LDFLAGS with cmake, e.g., LDFLAGS="-L/usr/lib -licuuc -licudata". Change the libdir to where the icu-uc library is installed.

OpenTTD 14.1 won't build with ICU >= 76, as ICU decided to split one of its components off into a separate library.

You could try to cherry-pick https://github.com/OpenTTD/OpenTTD/comm ... f6f1c7b96e, but then it won't be entirely 14.1 any more.

Or if possible drop to an earlier ICU version.
