Downgrade buildroot-built GCC toolchain from 12.x to 11.x #753

Closed jforissier closed 6 months ago

jforissier commented 6 months ago

GCC 12.x does not work with OP-TEE C++ TAs, causing a link error (excerpt from the build log on an arm64 host):

 The command '/bin/sh -c make V=1 RUST_ENABLE=n' returned a non-zero code: 2

While this may be mitigated with "make WITH_CXX_TESTS=n", we'd better select GCC 11.x which is know to work well and is consistent with what "make toolchains" would download on an x86_64 host (11.3.1).

After rebuilding toolchains I get the following:

So this patch seems to help, but it looks like there is still a reference to a 12.3.0 path in the build somewhere?

Update: I ran make clean and am trying a new build. 🤞

jforissier commented 6 months ago

@msgilligan make clean should fix the issue indeed. In fact rm -rf optee_os/out would suffice. I had the same error myself ;)

After a make clean, I'm getting:

Hmmm it worked for me (make check passed) but I must admit I started with 12.x then did not make clean but only rm -rf optee_os/out.

Could you try adding this:
