Cross compile libX11 source code error
 
Hi Guys,

When I cross compile libX11, and run the ./configure --prefix=/usr, I got the error as follow.

checking keysym definitions... configure: error: Cannot find keysymdef.h

However, I check the file keysymdef.h, it exists on my environment "~/sysroot/usr/include/X11/".

One more question is that there is no any output while I execute the "pkg-config --cflags xproto", but xproto is also installed on my environment.

Could anyone give me some suggestions?
Thanks so much!

Why not at least try a symlink to ~/sysroot/usr/include/X11/keysymdef.h in /usr/include/X11? If iy passes that, stop. It's searching your own system for files, so any libs it links in will be for the wrong OS. Do a 'make clean'

Where possible, it's better to do a chroot so that /usr seen by your compiling terminal is actually ~/sysroot/usr; then that sort of error doesn't occur. That may take some setting up. A look at the CLFS book on linuxfromscratch.org should help you.

Hi,

It doesn't work. I'm also confused why there is no any output for ""pkg-config --cflags xproto/xcb-proto/zlib"", but these xxx.pc files exist on my system.
I have no idea how to resolve this issue.

config.log is attached.
