Bug ID: 52106
Summary: Cross Compiling Clang Build is broken in Clang 13
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Tooling
Assignee: unassignedclangb...@nondot.org
Reporter: lancethepa...@gmail.com
CC: llvm-bugs@lists.llvm.org
I'm cross-compiling clang, lld and ldb for an arm32 cpu. I previously
cross-compiled clang 12.0.1, and am now trying to now compile clang 13.
With llvm 13 I'm now getting the error "clang-ast-dump: Exec format error". It
is attempting to run the cross-compiled 'clang-ast-dump' which of course won't
run on the build system. I built the host version of 'clang-ast-dump' but I
can't see any cmake variable to tell it the location of the build system's
'clang-ast-dump' like with the various TABLEGEN. I attempted putting it ahead
in the PATH but it doesn't automatically pick it up that way.
The issue was also brought up in this thread.
https://reviews.llvm.org/D93164/new/
Am I looking over a variable to pass this to cmake, or is there something I can
disable so it does not require 'clang-ast-dump'? I just want the c/c++
compiler, lld and ldb.
thanks,
Lance Fredrickson
