Portable Object Compiler builds on Debian 13 tested with gcc 14.2 (+deb13) byacc 2.0 20241231 and flex 2.6.4 as in the Debian repository. ncurses 6.5 20250216 can be used for building cursel on Debian (stty -a shows 128 x 48 linux terminal for me on linux kernel 6.12.48+deb13-amd64).
Portable Object Compiler builds on Debian 13 tested with gcc 14.2 (debian 19) byacc 2.0 20241231 and flex 2.6.4 as in the Debian repository. ncurses 6.5 20250216 can be used for building cursel on Debian (stty -a shows 128 x 48 linux terminal for me on linux kernel 6.12.48+deb13-amd64).
Curses (or "ncurses") version was 6.5-7 and Linux kernel 6.18.3-200.fc43. This required an additional "dnf install ncurses-devel" to get the ncurses include header files.
Portable Object Compiler builds on Fedora 43 with gcc 15.2.1 (byacc 2.0 from Fedora and flex 2.6.4). The "cursel" package builds with objc 3.4.12 on Fedora (tested with the Fedora "Server Edition" (console graphics) and after installing "dnf group install development-tools").
Add Fedora 43 (gcc 15.2.1) to Platform.txt
