Hi, Would someone be able to provide an example on how to : 1/ pass a vector of strings to ccall 2/ sort the vector of strings using c++ std::sort 3/ get the sorted string vector back in Julia Thank you

[image] gitboy16: @Ronis_BR , I do for sure understand that Julia is not R and I would be happy to believe you when you say that CxxWrap.jl is amazing, unfortunely my experience tells me otherwise. I don’t know maybe I am too dumb to understand how to use it, maybe you can educate me? First y…

I should have been more careful with my last comment about C++ being weird. I was thinking of the linkage, which is how different languages must communicate with each other. If you have a C or Fortran header file you can determine how to call a function. To do the same with a C++ header file you …

[image] Ronis_BR: Of course this example is the simplest way I found to perform what you described. There is probably 100 other alternatives much better and faster. I think it’s pretty much optimal. Note that it is also possible to just continue using the (C++) StdVector and convert to (Julia…

I have tried on a windows machine and I get the following error. Any idea how to solve that? D:\Code\test>clang++ --std=c++17 -shared -undefined dynamic_lookup -o libsort.dll -I C:\Users\gitboy\.julia\artifacts\ddaec29ab3e1def8127a1757203ee4a75c1bbead\include\ -ID:\julia-1.7.1-win64\julia-1.7.1\i…

Calling C++ to sort a vector of strings is more complicated than it seems. The issue is that C++ vectors and Julia vectors are different types, and so are C++ strings and Julia strings. You first need to decide whether you want to use C++ vectors or Julia vectors, C++ strings or Julia strings, or wh…

[image] gitboy16: I have tried on a windows machine and I get the following error. Any idea how to solve that? I haven’t tried using clang on Windows yet, but it looks to me like you are not linking to libjulia and libcxxwrap-julia. Even if you link in those, you probably need to compile lib…

Hi @barche , thank you , i have tried to use your cxxwrap-template. Here are the steps I did: download portable version of VS Code -install the cmake extension -downloaded cmake 3.22 portable and added it to PATH -I cloned your cxxwrap-template repo with git on my local drive -I have opened the…

In the workspace settings of cxxwrap-template you should add something like this: { "cmake.configureSettings": { "JlCxx_DIR": "C:/Users/user/source/repos/libcxxwrap-julia/build", "Julia_EXECUTABLE": "C:/Users/user/AppData/Local/Programs/Julia-1.7.1/bin/julia.exe" } } Here, C…

Thank you @barche for the details. I’ll continue posting here until they move your post to the other thread so people who are looking for help can follow the discussion. I did what you said and it seemed to have work as I got the following messages: [cmake] -- Configuration done [cmake] -- Generat…

Does your CMakeLists.txt have an install target? By default, those binaries should be located in $CMAKE_INSTALL_PREFIX/bin.

[image] gitboy16: But I don’t see any .dll or library being created that I can use with @wrapmodule . This just completed the build file generation phase, you still need to compile by hitting the “Build” button at the bottom or executing the VScode command CMake: Build. The compiled files sho…
