<div dir="ltr"><div dir="ltr">I made the library changes. I still get similar errors, so I guess it is a compiler compatibility issue.

<br>
you might want to check whether you indeed compiled Ipopt with the same <br>
C/C++/Fortran compilers that R is using.<br>
<br>
Further, this line shouldn't be in the linker flags that you posted:<br>
-LC:\CoinIpopt\build\x64\Ipopt\src\Common\.libs -lcommon<br>
libcommon.a is part of libipopt.<br>
<br>
Also libcoinmumps, lapack, blas, metis should be picked up from the same <br>
directory where the Ipopt library was installed, probably <br>
C:/CoinIpopt/build/x64/lib, not C:/CoinIpopt/build/x64/ThirdParty/*/.libs<br>
