| 4 | Subject: [PATCH] menuconfig,check-lxdiaglog.sh: Allow specification of ncurses |
| 5 | location |
| 6 | |
| 7 | In some cross build environments such as the Yocto Project build |
| 8 | environment it provides an ncurses library that is compiled |
| 9 | differently than the host's version. This causes display corruption |
| 10 | problems when the host's curses includes are used instead of the |
| 11 | includes from the provided compiler are overridden. There is a second |
| 12 | case where there is no curses libraries at all on the host system and |
| 13 | menuconfig will just fail entirely. |
| 14 | |
| 15 | The solution is simply to allow an override variable in |
| 16 | check-lxdialog.sh for environments such as the Yocto Project. Adding |
| 17 | a CROSS_CURSES_LIB and CROSS_CURSES_INC solves the issue and allowing |
| 18 | compiling and linking against the right headers and libraries. |
