<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">Hello and thanks to Silvio, z505, Giuliano.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">> Did you try the TProcess.Environment? :-)</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">Of course but, afaik, it is not what I want.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">I will try to explain with a concrete example (but I have much other in same case).</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">A project (uos) use c libraries.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">Mainly all that libraries are "run-alone" (only the called library is needed).</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">But there are some libraries that have dependencies.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;"><br>
</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">For example libopusfile.so needs libopus.so.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">If the main program load such library with loadlibrary(/my/directory/<span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">libopusfile.so</span>) ---> it will not work, even if libopus.so is in the
same directory that <span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
libopusfile.so.</span></span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;"><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">And even if doing
<span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
loadlibrary(/my/directory/</span><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">opusfile.so) before
<span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
loadlibrary(/my/directory/lib</span><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">opusfile.so</span> </span><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">) it will nor work because there
are no correspondance with the 2 <span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">loadlibrary()</span></span> </span>.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">And this is the challenge, how to load that dependeny if they are not in the lib-system directory.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">> Another way is passing before compiling: $ LD_LIBRARY_PATH=some-path make.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">Yes but for that the directory of dependencies must be known. In some case that dependencies come from elsewhere.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">> launch your application from a shell script, which does the work.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<span style="font-size: 12pt;">Ok, but it is much more complicate for end-user.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">

<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
