From: Matteo Croce <[email protected]>
Newest compilers complains if main() is declared without a return value,
this makes the test for ncurses-devel fail:
<stdin>:2:1: error: return type defaults to ‘int’ [-Wimplicit-int]
Which propagates as:
HOSTLD scripts/kconfig/lxdialog/lxdialog
*** Unable to find the ncurses libraries or the
*** required header files.
*** 'make menuconfig' requires the ncurses libraries.
***
*** Install ncurses (ncurses-devel) and try again.
***
Let main() return an int to fix the build.
