<p style="margin: 0px 0px 1.2em !important;">Dear toolkit users
and developers,</p>
<p style="margin: 0px 0px 1.2em !important;"><br>
</p>
<p style="margin: 0px 0px 1.2em !important;">With the latest
update of GCC to version 14, there is a known error that
prevents the compilation from taking place, preventing me from
compiling the toolkit.</p>
<p style="margin: 0px 0px 1.2em !important;">I’ve been trying to
do something which I probably should have some time ago to avoid
this kind of issues, while also granting some portability
between machines, which is to setup a virtual environment using
Conda to compile the toolkit.</p>
<p style="margin: 0px 0px 1.2em !important;"><br>
</p>
<p style="margin: 0px 0px 1.2em !important;">I am sending you this
e-mail because I’ve failed to compile the toolkit in a virtual
environment, where I am currently stuck with an error during the
linking phase. Before the update to GCC 14, and without the
virtual environment, I was able of compiling the toolkit without
any issue.<br>
</p>
<p style="margin: 0px 0px 1.2em !important;">Here are the steps
that I have performed:</p>
<ol style="margin: 1.2em 0px;padding-left: 2em;">
<li style="margin: 0.5em 0px;">
<p style="margin: 0px 0px 1.2em !important;margin: 0.5em 0px !important;">Activate
an empty virtual environment managed by a conda (or a
drop-in replacement) with the conda-forge repository
configured</p>

</li>
<li style="margin: 0.5em 0px;">

the following error from <code style="font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; font-weight: 550; background-color: rgba(119, 119, 119, 0.3); border-radius: 3px; display: inline;">ld</code>

<p style="margin: 0px 0px 1.2em !important;">To me, the previous

give the error <code style="font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; font-weight: 550; background-color: rgba(119, 119, 119, 0.3); border-radius: 3px; display: inline;">ld: unrecognised emulation mode: <something></code>

<p style="margin: 0px 0px 1.2em !important;">Removing the flag <code style="font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; font-weight: 550; background-color: rgba(119, 119, 119, 0.3); border-radius: 3px; display: inline;">-march=native</code>

<p style="margin: 0px 0px 1.2em !important;">and if I were to

will complain about something else.</p>
<p style="margin: 0px 0px 1.2em !important;">It really seems like
something is passing the flags onto <code style="font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; font-weight: 550; background-color: rgba(119, 119, 119, 0.3); border-radius: 3px; display: inline;">ld</code>
where it shouldn’t, but I cannot tell who and where.<br>
</p>
<p style="margin: 0px 0px 1.2em !important;"><br>
</p>
<p style="margin: 0px 0px 1.2em !important;">I should note that
compiling very basic programs in C in the virtual environment
doesn’t raise any issues, although I haven’t tested it very
thoroughly.</p>
<p style="margin: 0px 0px 1.2em !important;">Please do let me know
if you have any issues in rendering this e-mail!</p>
