What system are you using (that does not have pkgconfig) ?

Are you using microsoft development tools, minsys, or cygwin ?

I have been trying to get a msys system to build using github workflows (as a demonstration of how to do this). But have run into difficulities because the generated...

@guestieng I have been able to link eigen on a msys2 machine. Perhaps I can walk you through the steps. Start by following the instructions on msys2 on https://coin-or.github.io/CppAD/doc/cmake.htm#CMake%20Command.msys2 and...

@guestieng do not understand. Do you have a google or other id that we could chat over. My google id is bradley.m.bell. If you send a chat id to that...

I think I have solved the problem of building the tests, including the eigen tests, on windows using the Visual C++ compiler. See the following workflow file: https://github.com/coin-or/CppAD/blob/master/.github/workflows/conda-windows-eigen.yml Here is...

If you would like more support for installing without pkg-config, I suggest that we start with the use-case of eigen on windows. I think the best way to do this...

I think that working on a faster than CppAD::ipopt::solve interface to ipopt, along the lines suggested above, is worth while but not a simple effort. If someone is interested in...

I suggest you start by programming up the simple ipopt example https://github.com/bradbell/cppad_mixed/blob/master/example/ipopt_run.cpp And modifying it so that the derivative functions are calculated using CppADCodeGen. Once you have done that, you...
