A Problem About Cross Compiling

[Bora Sahin]

Hi,

Yes, this is what I want to learn. In fact, I told it in my first mail:

...
it is trying to use the host toolchain and libs, not the crosscompiled ones. (My host
system doesnt contain libxkbfile). After seeing that err msg I looked at Imakefile of it.

XCOMM Assumes local libraries installed in /usr/X11R6/lib
LOCAL_LIBRARIES = -L/usr/X11R6/lib $(XKBFILELIB) $(XONLYLIB)

ROOT_DEFINES = -DDFLT_XKB_CONFIG_ROOT=\"$(LIBDIR)/xkb\"

INCLUDES = -I.. -I$(EXTINCSRC)

This clearly states that it will use "-L/usr/X11R6/lib $(XKBFILELIB) $(XONLYLIB)". I am wondering is
this part of compiling to be done on the host system?
...

But I think I didnt express it clearly, sory!

Alexander> No. You need all X11 libraries on the host system for creating some tools

Alexander> Strange

As far as I understood, "UseInstalledOnCrossCompile" option should provide using some host tools,
but instead my build process tries to compile it, this is only xkbcomp. My host system is Debian.
May the problem stem from the build process not finding the xkbcomp in the host system, perhaps it
is not in the expected place?

Thanks...
