On analyzing the issue, it was found that rustc_llvm crate was present
at required path. However, it was very huge due to the presence of
debugging information. Hence, it was somehow not recognized as a valid
crate.
So we need to know more about this. What tool is being used to identify
the crate and has there been any changes to fix is since 1.54?
Also, please check this problem still happens with Alex's 1.55 upgrade:
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=akanavin/package-version-updates
The following patch removes the debug information from
rust-llvm-native which is built prior to rust-native but retains debug
information as required in rust-native binaries.
This is a functional work-around but I suspect that we'll hold-off
for a while before giving in and accepting it in oe-core/master.
Some people might find it useful so thanks for posting it as I suggested.
Hopefully we can better understand and fix the root cause.
Thanks Naveen,
