Hi there,
I've just encountered a problem when using python3-lxml on PTXdist
master branch:
$ python3
Python 3.7.10 (default, Aug 1 2021, 00:00:00)
[GCC 10.2.1 20200822] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from lxml import etree
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError:
/usr/lib/python3.7/site-packages/lxml/etree.cpython-37m-x86_64-linux-gnu.so:
undefined symbol: xsltGetProfileInformation
The problem arises through libxslt which is configured using
"--without-profiler" since commit 1940c3 .
Removing this option again allows to at least import etree from lxml. I
haven't done any investigation whether lxml may crash again elsewhere.
Are there any concerns about removing that configuration option again?
Best regards,
Felix

You should probably change it to --with-profiler instead unless that's
broken. Otherwise, I have no objections.
Please add a comment about breaking python3-lxml at runtime, so we know in
the future why this was changed.

Maybe Alexander had reasons to add "--without-profiler" without any
configuration option. He added three more options within the same patch
but left only this one fixed to "without".
So the compromise could be to add a new configuration option with
default value of "n" and add this configuration option as a dependency
to python3-lxml?
But as long as we don't know Alexander's reasons to do so, compiling
with the profiler option could break something else.

So lets ask him: Alex, can you comment on this? Did you have a reason other
than just disabling it because it seemed unnecessary?

I just checked diff between ./configure output of libxslt 1.1.29 and
1.1.34 and this is part of it:
+ --with-profiler Add the profiling support (on)
This means the option was new and I probably just set it to some
default. So yes, my reasoning was most probably it just seemed
unnecessary to me. If you need it set to --with-profiler or made
optional, go ahead the way Michael suggested.

Hi there,
I've just encountered a problem when using python3-lxml on PTXdist
master branch:
$ python3
Python 3.7.10 (default, Aug 1 2021, 00:00:00)
[GCC 10.2.1 20200822] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from lxml import etree
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError:
/usr/lib/python3.7/site-packages/lxml/etree.cpython-37m-x86_64-linux-gnu.so:

The problem arises through libxslt which is configured using
"--without-profiler" since commit 1940c3 .
Removing this option again allows to at least import etree from lxml. I
haven't done any investigation whether lxml may crash again elsewhere.
Are there any concerns about removing that configuration option again?
Best regards,
