Another test, without my PR 12876.
Python compiled without RPATH:
$ ./configure --prefix=/opt/py38
$ make
$ make install
$ /opt/py38/bin/python3.8 -m sysconfig|grep LIBDIR
LIBDIR = "/opt/py38/lib"
Build lxml manually using "setup.py build_ext --rpath /opt/py38/lib" (which is
equal to the Python sysconfig LIBDIR variable):
$ /opt/py38/bin/python3.8 -m venv ~/opt_env
$ wget

$ tar -xf lxml-4.3.3.tar.gz
$ cd lxml-4.3.3/
$ LD_LIBRARY_PATH=/opt/py38/lib ~/opt_env/bin/python setup.py build_ext --rpath
/opt/py38/lib
$ objdump -a -x
build/lib.linux-x86_64-3.8/lxml/etree.cpython-38m-x86_64-linux-gnu.so|grep -i
rpath
^^ no output, no RPATH
Hum, distutils removed the RPATH because it's equal to Python sysconfig LIBDIR?
Without my PR? Strange.
New try with a different RPATH:
$ rm -rf build
$ ~/opt_env/bin/python setup.py build_ext --rpath /custom/rpath
$ objdump -a -x
build/lib.linux-x86_64-3.8/lxml/etree.cpython-38m-x86_64-linux-gnu.so|grep -i
rpath
RUNPATH /custom/rpath
The RPATH is correctly written in the .so file.
... Now, I'm confused. Is PR 12876 useless? Was distutils already fixed?
