title: PVM library (Parallel virtual machine) installation problems when use make
body: <p>I'm trying to install PVM library (<a href="https://netlib.org/pvm3/pvm3.4.6.tgz" rel="nofollow noreferrer">https://netlib.org/pvm3/pvm3.4.6.tgz</a>) <br />
  I successfully extracted the package in my $HOME <br />
  Following the Readme instructions I have set my env variable PVM_ROOT=$HOME/pvm3 at the end of my $HOME/.bashrc file and I have append the content of the file $HOME/pvm/lib/bashrc.stub to the .bashrc and uncommented the lines 'export PATH=$PATH:$PVM_ROOT/lib/PVM_ARCH' and 'export PATH=$PATH:$PVM_ROOT/bin/PVM_ARCH'<br />
  After reopening the bash all my env variables are there so I guess it's all good until there.</p>
  <p>But THEN I go in ~/pvm3 an when I type 'make' I get a list of warning the first time:</p>
  <p>Here is a sample of the warnings I get when running make the first time</p>

  <p>I don't know if it worked but anyway I tried calling pvm and it kind of worked:</p>
  <pre><code>~/pvm$ pvm
  pvm&gt; halt
  halt
  completed
  </code></pre>
  <p>xpvm command is unfound though and
  I thought that it was alright so tried one of the code examples given in pvm3/examples</p>
  <pre><code>$ cc -o hello hello.c
  hello.c:37:10: fatal error: pvm3.h no such file or directory of this type
      37 | #include &quot;pvm3.h&quot;

  compilation terminated.

  <p>fine, the documentation at <a href="http://www.netlib.org/pvm3/faq_html/node62.html" rel="nofollow noreferrer">http://www.netlib.org/pvm3/faq_html/node62.html</a> gives an answer for this kind of problems</p>

  <p>I tried with gcc and cc, I tried on different distributions: kali-rolling 2020.3 on a 64bits computer and ubuntu-20.04.1 on a 32 and 64bits computer.<br />
  I plan to try with cshell instead of bash but I think it's the makefile that makes it difficult or maybe I did not specify the architecture well enough. I'm also not a regular C coder so I might have done some obvious mistake.<br />
  I would also install it on windows 10 but let's not rush things ahah<br />
  Thanks for your time</p>
