Hi. I'm on Arch Linux and import casadi in python is borked for me with the following output:

$ ipython

IPython 8.25.0 -- An enhanced Interactive Python. Type '?' for help.

Any idea what could be going wrong here? I build casadi via the AUR package: https://aur.archlinux.org/packages/casadi

[greyltc]

Instead of using the AUR package. I've rebuilt casadi following https://github.com/casadi/casadi/wiki/InstallationLinux
but the error is the same:

Might be related to the SWIG version. There was a recent fix (#3540) to get CasADi to work with SWIG 4.2.1. You might want to build the main branch or use an older SWIG version.

[greyltc]

@jaeandersson, my build two comments up does build from the main branch, and still shows the issue, right?

Did you try a older SWIG build? I think that the one used for the CasADi binary builds is https://github.com/jaeandersson/swig/tree/matlab-customdoc

[greyltc]

No, I haven't tried downgrading swig yet

[nim65s]

I adopted casadi on AUR, and now it build fine, both on my daily desktop and in a clean docker.

python -c "import casadi" seems fine too.

@greyltc : I think you might need to ensure everything is clean and up to date on your side, and then try again from AUR.

[greyltc]

@nim65s I'm glad it's working for you! That means this is probably something strange in my setups then. I've got this on 3 seperate machines that are all up to date. I've built in a clean chroot. I've done a minimal build outside of makepkg (as above). It's always the same. I saw you adopted the package and made a bunch of changes, I haven't tried your new package yet.

What does nm /usr/lib/python3.12/site-packages/casadi/_casadi.so | grep _ZN6casadi10differenceERKSt6vectorINS_2MXESaIS1_EES5_ print for you? For me it's:

$ nm /usr/lib/python3.12/site-packages/casadi/_casadi.so | grep _ZN6casadi10differenceERKSt6vectorINS_2MXESaIS1_EES5_
                 U _ZN6casadi10differenceERKSt6vectorINS_2MXESaIS1_EES5_

I can't figure out where this symbol is coming from. I'm thinking something needs to get rebuilt, but I can't figure out what it is.

[nim65s]

Hum, I have no idea what is going on with this one:

$ nm /usr/lib/python3.12/site-packages/casadi/_casadi.so
nm: /usr/lib/python3.12/site-packages/casadi/_casadi.so: no symbols
$ python -c "import casadi._casadi; print(dir(casadi._casadi))"

[tmmsartor]

Just to add something on this:

compiling with swig-4.2.1 (the version currently used in archlinux):

$ nm _casadi.so | c++filt | rg casadi::difference
U casadi::difference(std::vector<casadi::MX, std::allocator<casadi::MX> > const&, std::vector<casadi::MX, std::allocator<casadi::MX> > const&)

while compiling with swig-4.1.0 that symbol is not present in _casadi.so (python interface), same is true for pypi binaries, (both with branch main).

So I am guessing this is a swig-4.2.1 issue but different from #3540

I don't know why this happen, and why this is a problem given that the symbol is defined in libcasadi.so.

NB: the symbol is the same I just demangled it:

$ echo "_ZN6casadi10differenceERKSt6vectorINS_2MXESaIS1_EES5_" | c++filt
casadi::difference(std::vector<casadi::MX, std::allocator<casadi::MX> > const&, std::vector<casadi::MX,std::allocator<casadi::MX> > const&)

[tmmsartor]

It seem commits from #3723 fix also this issue, using basemodelica branch both version of swig (4.1 and 4.2.1) include the symbol : casadi::MX::difference(std::vector<casadi::MX, std::allocator<casadi::MX> > const&, std::vector<casadi::MX, std::allocator<casadi::MX> > const&) which get correctly resolved

[tmmsartor]

#3724 seems to fix this on main. To try this on archlinux there is another AUR package casadi-git which compiles branch main, (also has less optional dependencies than the other package).
Can be installed with $ paru -S casadi-git (where paru is one of available AUR helpers)
