toolchain issue with with-libtool-sysroot unrecognized

toolchain issue with with-libtool-sysroot unrecognized

Hi,

I tried to follow the steps from the official Yocto toolchain 
documentation as in :
http://www.yoctoproject.org/docs/1.4.2/adt-manual/adt-manual.html#creating-and-running-a-project-based-on-gnu-autotools

When I run the configure step, I get a warning :
configure: WARNING: unrecognized options: --with-libtool-sysroot

This shouldn't be so bad, but unfortunately, because of this warning, I 
get the following issue: when I try to run the generated binary, I get :

/lib/ld-linux.so.3: No such file or directory


So it's clear that because configure doesn't understand the libtool 
sysroot parameter, it won't link my executable to the appropriate 
library path. ld-linux.so.3 is indeed present under sysroots/lib. So if 
the --with-libtool-sysroot were understood, that would work perfectly.

Has anyone any clue on this? I google the error but couldn't find any 
valuable information


Regards
Jay

It seems to be an issue with your autotools-based project as it works
fine in all recipes which use autotools in Yocto.

not so sure. I see the same configure warning in many other recipes. It 
doesn't prevent the binary from working, it just prevents it to be 
launched from within the SDK.

You must be careful how to call configure and like; so it most
probably an error in configure.ac/Makefile.am or how you are calling
the configure script.

I use autotools based projects in toolchain daily at our projects and
customer projects and it works fine. Without further research in logs
and code access it is hard to do a better bet.

You are right. It's impossible to tell more, so here are more details:

Makefile.am:
SUBDIRS =
bin_PROGRAMS = hello


configure.ac:
AC_INIT([hello], 0.1.0, trevor.woerner@linaro.org, hello)
AC_CONFIG_SRCDIR(hello.c)
AC_CONFIG_AUX_DIR(.)
AM_INIT_AUTOMAKE([foreign no-dist-gzip dist-bzip2 1.9])


SUBDIRS=""

AC_PROG_CC
AC_PROG_INSTALL
AC_PROG_LN_S

AC_OUTPUT(Makefile)

hello.c:
#include <stdio.h>
main()
         {
            printf("Hello World!\n");
         }


I don't know what kind of logs I should post to help investigate the issue?
