I am trying to get the Yocto Eclipse plug-in setup so that I can build my
application from Eclipse. I am *almost* there, but the final build is not
working. I'm assuming there are some path/rights issues somewhere in the chain
because I can build from the command line. I'm looking for some help in
figuring out where the difference is.
I am using Fedora 21 64-bit for a host system. I am using Eclipse Kepler; I
also have Eclipse Luna installed, but I had to install Eclipse Kepler since
another plugin I am using does not yet have support for Eclipse Luna. I am on
poky/daisy HEAD and have been able successfully build my image (image based on
core-image-minimal with a few extra applications). Under Eclipse Kepler, I
installed the pre-build plug-in from the Yocto Eclipse Update Site as
instructed in the Yocto Project Development Manual for Poky 1.6.2. I am using
my existing toolchain in the build directory, so I issued "bitbake
meta-ide-support" to generate the cross-toolchain support. I then followed the
instructions under "Extracting the Root Filesystem" in the ADT Manual to
extract the root filesystem. Specifically, I sourced the newly created
environment script and then called "runqemu-extract-sdk <my_built_image.tar.gz>
<sysroot_destination_directory>". Then, from Eclipse I setup the Yocto Project
AD
T for a "Build System Derived Toolchain", I set the Toolchain Root Directory
to my Poky build directory, and I set the Sysroot location to my extracted
sysroot directory.
After the initial environment setup, from Eclipse I selected File->New->C
Project, and selected a "Hello World ANSI C Autotools Project" under the "Yocto
Project ADT Autotools Project" options. For the new project, if I select
"Reconfigure Project" the configuration fails with the following error:
checking whether the C compiler works... no

Note that <home_path> included the actual path to my home directory in
config.log but I changed it to <home_path> for the purposes of this e-mail
(yes, I'm paranoid).
However, if I instead open a terminal, go to my project directory and do the
following:
source
<path_to_Poky_build_directory>/environment-setup-arm926ejste-poky-linux-gnueabi
./configure ${CONFIGURE_FLAGS}
The project configures without a problem. I can then either build from the
command line or I can build from Eclipse. It seems very odd to me that the
configure doesn't work from Eclipse, but once it is configured I can build
without issue. Anyone have any ideas as to what I have wrong in my setup?
Thanks,
Bryan
