I am having trouble configuring my SDK to use the meta-clang compiler-rt
component properly.
How do I configure my build so meta-clang brings in compiler-rt and generates
the libclang_rt.binutils-x86_64.a library I require?
When I attempt to build in "compiler-rt" component I get the CMAKE Error shown
below.
No matter how I try, for example:
TOOLCHAIN_TARGET_TASK_append = "compiler-rt-static-dev compiler-rt-dev"
Or:
SDK_EXTRA_TOOLS = " \
nativesdk-cmake \
nativesdk-clang \
nativesdk-compiler-rt \
"
I get the "cmake" error described below.
(1) What Is this the correct method to add this components to my SDK ?
(2) I do not understand how to resolve this , all are yocto based components,
the only llvm components are pulled in by meta-clang, what am I expected to
edit to resolve ?, and how ? Can someone explain to me what this error is
attempting to convey, and what I am doing wrong ?
(3) Is it correct to expect the cmake and clang components to work together
under yocto?
(4) I do not want the tools built into my kernel just the SDK for development,
Is there better way to do what I want to do here ?
Note: My target and host systems are both x86-64...
And, yes, the "-rtlib-libgcc" works for my basic test code and bypasses
requiring compiler-rt, but I would like to understand what is going on below
and be able to build correctly...
Synopsis of issue:
-----------------------
When I build my SDK, I setup the following:
SDKMACHINE = "x86_64"
SDKIMAGE_FEATURES_append = " staticdev-pkgs"
TOOLCHAIN_HOST_TASK_append = "${SDK_EXTRA_TOOLS}"
SDK_EXTRA_TOOLS = " \
nativesdk-cmake \
nativesdk-clang \
"
require conf/distro/include/yocto-uninative.inc
INHERIT += "uninative"
My SDK builds and installs without issue...
Running a very basic example produces the following issue:
09:22 smonsees@yix490016 ~/yocto/test>make hello x86_64-poky-linux-clang -m64

The file in question does not exist on my system.
If I add "nativesdk-compiler-rt" like so:
SDK_EXTRA_TOOLS = " \
nativesdk-cmake \
nativesdk-clang \
nativesdk-compiler-rt \
"
I get the following error:
