I want to have one recipe build with clang instead of gcc (gcc is
being used for the rest of the image). I thought this was as simple as
adding the following line to the recipe:
TOOLCHAIN = "clang"
Adding that line, and adding meta-clang to bblayers.conf, did get the
llvm/clang compiler built and installed to recipe-sysroot-native. But
the moment it starts to build the package, it fails immediately with:
| fatal error: 'string' file not found
| #include <string>
| ^~~~~~~~
Did I miss a step? That seems like a pretty basic thing that would be
needed for using a toolchain. If feels like I'm missing something;
like I need to add something else to my local.conf. Thoughts?
Suggestions?
I went looking for examples of recipes using clang and found
meta-openembedded/meta-oe/recipes-support/tbb.bb which includes:
COMPILER ?= "gcc"
COMPILER_toolchain-clang = "clang"
Odd. Why "COMPILER" and not "TOOLCHAIN" like meta-clang's README mentions?
Best regards,
Trevor
