No ipopt in the system

[adalseno (Andrea Dalseno)]

Hi, I installed ipopt via

sudo port install ipopt

The installation went fine

sudo port install ipopt

the port is active

  ipopt @3.14.12_1 (active)

but ipopt is not there:

❯ which ipopt
ipopt not found

I installed ipopt in a conda environment using conda, and, within that environment, it works fine, but I would prefer to have it system-wide. I am on Mac Os Catalina.

What went wrong? Isn't the port supposed to install ipopt? Thanks in advance

This port doesn't appear to install an executable, just a library.

You can tell by running port contents ipopt or by looking at the ​port web site (the Files part of the Port Health section) what files the port installed. The port's description, "COIN-OR Interior Point Optimizer IPOPT", doesn't tell me whether it is supposed to install an executable.

Yes, and if you check a build system you’ll see that it builds library: ​https://github.com/coin-or/Ipopt/blob/stable/3.14/src/Makefile.am

[catap (Kirill A. Korinsky)]

I've made some investigation. For example Debian also install only libraries: ​https://packages.debian.org/source/sid/coinor-ipopt

But, if somehow ask it to use system ASL it will build binary.

So, I've asked upstream ​https://github.com/coin-or/Ipopt/issues/690 because it uses it's own macroses for autotools to detects ASL, Mumps and so on which should be rebuild by their build scripts ​https://github.com/coin-or-tools

For example Mumps build is quite frigiele and rebuild it via ​https://github.com/coin-or-tools/ThirdParty-Mumps seems like a nigth mare.

The first PR ​https://github.com/macports/macports-ports/pull/20152 to bring ASL into MacPorts is ready. After it's merged I'll open the next one which builds ipopt.
