Hello Chan,
I have been working to a similar goal, to include clang in the toolchain to be
used for compiling applications to run on the target. Using clang to compile
the OS and kernel are not required or desired by me.
You may get some insight from the thread I started in November on the subject.
I'm not sure that this contains all of the posts on the subject. You may want
to search the archive for November.
I have not been successful yet in getting clang actually packaged in the
toolchain, in the Yocto build, but at least it builds. I have a postbuild
script that takes the built clang compiler from the work directory and jams it
into the SDK tarball that is embedded in the sdk install script.
-Jim-

Hi guys,
Before I go to my errors let me outline the steps I took.
I started off with the LLVM recipe that I got from
http://cgit.openembedded.org/meta-openembedded/tree/meta-oe/recipes-core/llvm .
Then I added the following to llvm.inc's do_configure_prepend() because I
wanted to compile Clang, rt-compiler and Clang tools together with LLVM. I also
added the SRC_URI and Licensing for all of them but I don't think that's the
main issue here:
mv ${WORKDIR}/cfe-${PV}.src ${S}/tools/clang
mv ${WORKDIR}/compiler-rt-${PV}.src ${S}/projects/compiler-rt
mv ${WORKDIR}/clang-tools-extra-${PV}.src ${S}/tools/clang/extra
The three lines copies the extracted files to the source directory because
that's the way the LLVM does it according to
http://clang.llvm.org/get_started.html .
The compilation went well but I got "Files/directories were installed but not
shipped error". The log is at http://pastebin.com/e831Ex9E .
I then tried to add the install -d ${D}${libdir}/clang to do_install() function
but no good..hence my reason of posting here to have more eyes looking at this.
Let me know if you need more info.
Thanks,
Chan Kit

I'm pretty sure this is because anonymous functions don't get executed until
finalize() is called, which is towards the end of parsing; the "require"
statement must be handled immediately. Try this instead:
---------------- snip ----------------
def get_java_package(d):
TA = d.getVar('TARGET_ARCH', True)
if TA == "arm":
javaPkg = "oracle-jse-ejre-arm-vfp-hflt-client-headless"
elif TA == "i586":
javaPkg = "oracle-jse-jre-i586"
elif TA == "x86_64":
javaPkg = "oracle-jse-jre-x86-64"
else:
raise bb.parse.SkipPackage("Target architecture '%s' is not supported
by the meta-oracle-java layer" % TA)
return javaPkg
JAVA_PKG = "${@get_java_package(d)}"
require ${JAVA_PKG}.inc
---------------- snip ----------------
The question is though, do you really need a separate inc file for each
architecture? You can use overrides for this sort of thing e.g.:
---------------- snip ----------------
SOMEVAR = "default value"
SOMEVAR_arm = "value if arm"
SOMEVAR_x86-64 = "value if x86-64"
---------------- snip ----------------
Cheers,
Paul

I recommend you to file a bug here https://bugzilla.yoctoproject.org/ if
not done already. You may get a proper answer on armhf support there. From
what I see, (someone please correct me if I am wrong), there is no prelink
dynamic link armhf patch. You can also create and submit the patch for
review. AFAIK, you are gonna need to something like below,
.dynamic_linker = "/lib/ld-linux-armhf.so.3" in arch-arm.c.
This is not tested though. Please do a test yourselves.
