<div dir="ltr">Hi Antonio,<div><br></div><div>Thanks for the report, I will fix the issues you highlighted.

That's completely right, my mistake. I stopped when I saw that, but in fact the error was<br>
<br>
ld: library not found for -lSystem<br>
collect2: error: ld returned 1 exit status<br>

<br>
I learnt this was an Homebrew issue, and by<br>
<br>
brew reinstall gcc<br>
<br>
I was able to configure, and then make, the whole FlopC++ thing (hence, OSI) using gcc-8.<br>
<br>
Well, almost: one has to use OSI 0.107.9 and Cbc 2.9.9, which is not what is fetched by FlopC++. Also, I was still getting an error from FlopC++:<br>
<br>
../.././../src/Coin-OR/coin-FlopCpp/FlopCpp/src/MP_set.hpp:212:9: error: no matching conversion for functional-style cast from<br>
'const flopc::SUBSETREF' to 'flopc::MP_domain'<br>
return MP_domain(s);<br>
<br>
Thanks to Enrico Gorgone, I now know that this can be solved by changing line 211 of ../FlopCpp/src/MP_set.hpp from<br>
<br>
MP_domain& operator()(const SUBSETREF& s) {<br>
return MP_domain(s);<br>
}<br>
<br>
in<br>
<br>
const MP_domain& operator()(const SUBSETREF& s) {<br>
return MP_domain(s);<br>
}<br>
<br>
Sorry for not spotting my own Homebrew issue. Hope this will still be useful to somebody.<br>
<br>
Best<br>
<br>
