Implicit declaration of "mvaddwstr" function despite ncursesw (wide variation of ncurses) being explicitly linked. Compiling src/example. The utilities are wrappers around ncurses library functions, which means that some special ncurses is a programming library providing an API, allowing the programmer to write text user interfaces in a terminal-independent manner. `Ada95' directory, you'll find code and documentation for an Ada95 binding of the curses API, to be used with the This makes Ncurses build and install shared C++ bindings. Edit Makefile. It looks like you need to add -I c:/MinGW/include to your compile command line (or however you specify a path on MinGW). If a package doesn't compile with the compiler present in iuc-tools, we know this upfront and the tool won't get into the toolshed until it's solved (preferably upstream). Clang 10 fails to link C++ application with CMake on macOS 10. I am compiling for maximum performance but it fails due to dependency errors. Use of this feature is not recommended, as it essentially includes an entire termcap compiler in the ncurses startup code, at significant cost in core and startup cycles. But we can work around it: copy the new ncurses header files into our Sources/Cncurses directory; replace __NCURSES_H through something different, e. m4. h> . See the file TO-DO for things that still need doing, including known bugs. I use this code to compile a example file. x+. – jww Arch Linux does not provide cross-compiler packages for ncurses (actually I'm unaware of any cross-compiler packages for ncurses, so this is not a special misfeature of Arch). /progs directory which was build using the cross-compiler.
