Clib4 now has a working ncurses library support. But to use the library you need to configure AmigaOS4 so the library can find the correct terminal.
In the package there is a directory called terminfo that contains clib4 terminal specifications.
This directory needs to be copied into OS4 ENVARC: folder. Final tree must be this one:
Once files are copied you can use setenv command in your shell to choose the right file you want to use.
The default one is amiga-clib4. This version supports 16 colors and it is working very well even if it has some flaws occasionally.
amiga-clib4-mono is the mono version but it has some problems when you scroll a line horizontally and exceed the last column.
So for example to set amiga-clib4 terminal, use:
setenv TERM amiga-clib4
Both files are created via termcap.os4 file using tic command present into ncurses package.
To use ncurses library, install or compile ncurses package and add -I{SDK_PATH}/local/clib4/ncurses to your makefile
To compile ncurses use this configure command line:
./configure --host=ppc-amigaos --prefix={SDK_PATH}/local/clib4 CFLAGS="-O3 -mcrt=clib4 -gstabs" CXXFLAGS="-O3 -mcrt=clib42 -gstabs" LDFLAGS="-mcrt=clib4 -athread=native" --without-dlsym --without-ada --with-termpath=ENVARC:termcap.os4 --disable-db-install --without-manpages -disable-rpath-hack --enable-getcap --disable-stripping --enable-termcap --enable-wgetch-events --enable-sigwinch --enable-ext-colors --with-terminfo-dirs=ENVARC:terminfo --with-default-terminfo-dir=ENVARC:terminfoReplace {SDK_PATH} with your SDK installation path.
It is also possible to enable wide char support but since AmigaOS4 shell doesn't support unicode it is useless and charaters are rendered wrong.
