I've been having a few other issues with Eclipse (Install New Software menu item disappearing, other plugins disappearing after restarting, etc.), so I uninstalled eclipse, deleted my ~/.eclipse and workspace directories and re-installed Eclipse. I need to run Eclipse Kepler (another plugin I'm using isn't ready for Eclipse Luna), so I followed these instructions for installing Eclipse by hand: http://www.92wiki.com/en/blog/detail/install-eclipse-kepler-on-fedora-17-18-19-centos-red-hat-rhel-5-6. I also edited my environment setup script as suggested. I then reinstalled all necessary plugins as described in the ADT manual. I pointed the toolchain to my build directory and the sysroot location to my extracted sysroot. I then followed the steps in the ADT manual to create a new Hello World Yocto ADT project. I verified the SDKTARGETSYSROOT environment variable in the new project points to my extracted sysroot. When I attempted to build, I get the following output: Invoking autogen.sh in build directory: /<home_path>/workspace/adt_test/ Command-line environment variables: CFLAGS=" -g -O0 --sysroot=/<home_path>/extracted_sysroot_1.6.2" CXXFLAGS=" -g -O0 --sysroot=/<home_path>/extracted_sysroot_1.6.2" LDFLAGS=" --sysroot=/<home_path>/extracted_sysroot_1.6.2" CPPFLAGS=" --sysroot=/<home_path>/extracted_sysroot_1.6.2" sh -c "/<home_path>/workspace/adt_test/autogen.sh --with-libtool-sysroot=/<home_path>/extracted_sysroot_1.6.2 --target=arm-poky-linux-gnueabi --host=arm-poky-linux-gnueabi --build=x86_64-linux --with-libtool-sysroot=/<home_path>/extracted_sysroot_1.6.2" aclocal: warning: couldn't open directory '/<home_path>/extracted_sysroot_1.6.2/usr/share/aclocal': No such file or directory configure.ac:16: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated.

First, the system couldn't find aclocal in my extracted sysroot. I took a look in the directory listed, and aclocal is not in there. I think the configure script also found the build system's install and mkdir (/usr/bin/install and /usr/bin/mkdir). I don't know if there is supposed to be one of these in the extracted sysroot or not, but I thought it was worth noting. On a possibly related topic, I noticed that the Eclipse Indexer is using the build system's header files. For example, if I open the main source file from the Hellow World application, place my cursor on the line "#include <stdlib.h>" and hit F3, /usr/include/stdlib.h opens up instead of stdlib.h from my toolchain. Under the Eclipse project, for the listed Includes directories it has the following: /usr/include /usr/lib/gcc/x86_64-redhat-linux/4.9.2/include /usr/local/include Any thoughts on how to fix these issues? Thanks, Bryan
