Could not install Ipopt using install_ipopt.sh

I tried to install Ipopt using install_ipopt.sh on Ubuntu 18.04 64bit.
But, the error occurs in make install process. The error message is as follows.

/usr/bin/install -c .libs/libcoinasl.so.1.3.6 /usr/local/lib/libcoinasl.so.1.3.6
/usr/bin/install: cannot create regular file '/usr/local/lib/libcoinasl.so.1.3.6': Permission denied
Makefile:740: recipe for target 'install-exec-local' failed

I checked install_ipopt.sh. And, I enumerate my opinion.

  • Install path is defined by prefix=/usr/local
  • But, this script call make install
  • I think that this script should call sudo make install

There's actually fairly good reasons to use make install instead of sudo make install - you can check this out in this Stack Overflow post. As they mention in the post, it's preferred to use usr/local, which you can otherwise give yourself permission for (I believe chmod u+w /usr/local should work).
