Help Installing Ifopt-Ipopt w/o catkin about ifopt HOT 13 CLOSED

I will submit a pr that you can look at in the next few days.

@shoshievass I have a similar need, so I'll have a crack at this tomorrow.

No worries. I actually thought that I had updated the PR with other work I had done, but I guess I was mistaken. For your reference, https://github.com/jwdinius/ifopt/tree/pure_cmake.

I followed the outline provided by kindr in most places, including setting up package exporting. Now, ifopt_ipopt(snopt) can use find_package() to find ifopt_core during the local superbuild or via an external cmake project. Please have a look if you are interested in exporting these projects, which might be handy when trying to install ifopt from within another project (like how kindr is built within https://bitbucket.org/adrlab/ct).

I was able to verify that the packages were able to found from an external cmake project built with unit tests. Hopefully something in my repo will be of use to you. Cheers!

Since catkin is not installed in you system, you will have to remove the "find_package(catkin REQUIRED)" line and all others involving "catkin". Then you will need to ensure that when building "ifopt_ipopt", this project finds "ifopt_core", possibly through cmake's "add_subdirectory()" command and others. This linking of projects is where catkin is most handy.

@jwdinius Awesome! Please let me know how it goes!

from ifopt.

I have submitted a PR for this: #15. Please review and provide feedback when you get the chance.

from ifopt.

Great, thanks @jwdinius !
I'll have a look at it in the next few days.

I'm changing the pr to work-in-progress so you all can have a look at it and make comments. I would like to clean up the implementation a little more before it's merged.

Hi @jwdinius, @shoshievass
Building with pure cmake works now (see #17), please let me know if you experience any problems.

Thanks for your help on this @jwdinius, sorry I couldn't merge your PR, I decided to do some beneficial structural code improvements as well while adding the cmake features.

Hi,
I am trying to build using CMake. I have made changes according to instructions in the CmakeLists.txt. But I am getting the following error.

~/MyProject$ ls
bin build CMakeLists.txt example.cpp libipopt2.so

$cmake --build build -- -j3

@sapan-ostic It looks like ipopt can't find blas. Are you sure that your libipopt.so works as expected? Did you follow the build stages at https://www.coin-or.org/Ipopt/documentation/node10.html? Are you working on linux? You could just apt install ipopt and it will handle the dependencies for you. If you run into other problems, you could look at my fork https://github.com/jwdinius/ifopt. I also wrote a blog post about the conversion process https://jwdinius.github.io/blog/2018/cmake/. Hopefully one of these references will help. Good luck!

I am having the same issue as @sapan-ostic.
I try to compile the ex_test_ipopt.cc using cmake.

find_package(IPOPT 3.11.10 REQUIRED)
find_package(ifopt 2.0.1 REQUIRED)
set(LIB_IPOPT ifopt_ipopt)
add_executable(${LIB_IPOPT}-example ex_test_ipopt.cc)
target_link_libraries(${LIB_IPOPT}-example
  PUBLIC 
    ifopt::ifopt_core
    ifopt::ifopt_ipopt
)

And it gives me:

I solved this by reinstall the ipopt with BLAS. Aka, remove the coinor-libipopt-dev, and compile ipopt from source after get the Thirdparty solver BLAS.
