Bug ID: 24144
Summary: libcxx_tsan and libcxx_msan-with-call get installed
with bad prefixes
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: compiler-rt
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
To reproduce:
In /tmp/foo:
$ svn export http://llvm.org/svn/llvm-project/llvm/trunk llvm
$ svn export http://llvm.org/svn/llvm-project/compiler-rt/trunk
llvm/projects/compiler-rt
$ svn export http://llvm.org/svn/llvm-project/libcxx/trunk llvm/projects/libcxx
$ svn export http://llvm.org/svn/llvm-project/libcxxabi/trunk
llvm/projects/libcxxabi
$ svn export http://llvm.org/svn/llvm-project/cfe/trunk llvm/tools/clang
$ mkdir build && cd build
$ CC=clang CXX=clang++ cmake -GNinja ../llvm
$ DESTDIR=/tmp/install ninja install
Now look in /tmp/install, it will contain files such as:
/tmp/install/tmp/foo/build/projects/compiler-rt/lib/tsan/libcxx_tsan/include/c++/v1/limits
That's not good, because the installed files are what becomes part of release
tarballs.
>From what I understand, these two special libcxx builds are only used for
testing, so not intended to be part of the overall install target. That's why
they get a prefix inside the object dir. But then DESTDIR ruins it by getting
them installed somewhere else.
I wonder if we can suppress DESTDIR somehow when installinb libcxx_tsan.
