Hi,
I'm trying to get the SDK to be able to run the kernel's "make
menuconfig" target
using nativesdk-ncurses from the SDK. Looking at
http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-4.4/commit/scripts/kconfig/lxdialog/check-lxdialog.sh?h=standard/beaglebone&id=badf6fedf455958fe0ff3c060c8e3965ef6d80dc
I figured out I could pass CROSS_CURSES_[INC,LIB], but the second chunk
in that patch looks weird:
elif pkg-config --cflags ncurses 2>/dev/null; then
echo '-DCURSES_LOC="<ncurses.h>"'
+ if [ x"$CROSS_CURSES_INC" != x ]; then
+ echo "$CROSS_CURSES_INC"
+ exit
+ fi
elif [ -f /usr/include/ncursesw/curses.h ]; then
echo '-I/usr/include/ncursesw -DCURSES_LOC="<curses.h>"'
(I had to do manual indentation with spaces in gmail)
Is the indentation or the logic incorrect ?
In the commit itself, the indentation is fine.
That block of code is just dumping flags that are used in the
build. So in this case, it is correct. If the variable is
non empty, it is echoed and then processing exits.
The check if CROSS_CURSES_INC is non-empty is only done if the preceeding
"elif"-check is true, and not unconditionally as one would expect
judging by the indentation.
Yep, that's the point. It goes to pkgconfig first, and then falls
back to that.
The indention is fine in the actual repository.
