How to build?

[hacker-DOM]

Hi there, I'm not very proficient with C, just trying to typeset some nice math :)

I clone the repo on a Mac and ran cmake, then make and got the following output:

[  1%] Building CXX object CMakeFiles/diagon_base.dir/src/translator/Translator.cpp.o

I googled the errors and got here and then here, which together seemed to provide an answer.

Based on that, I tried running make CXXFLAGS='-std=c++11'. However, I got the same output. Any help, thanks!

Thanks for reporting this. This means there are some target where I missed executing:

  set_property(target PROPERTY CXX_STANDARD 17)

and you compiler default is less than C++11.

I will submit a fix.

BTW, you can use Diagon directly on: https://arthursonzogni.com/Diagon/

[ArthurSonzogni]

Could you check the fix worked for you?

Hello, I'm trying to build the project on a mac so that I can try to use the vim plugin, but I have barely no experience building c++ projects.

I executed cmake CMakeLists.txt and then make and it failed at 87%.

Does anyone know what I could've missed?

macOS user here – I ran into the error that @execb5 ran into as well.

[ArthurSonzogni]

@execb5, @nchase,

To build it, you have to:

mkdir build;
cd build;
cmake ..;
make

The dependencies 'uuid-dev' and 'libboost-graph-dev" might be required.

I think I will add some github workflow for you to be able to download binaries directly.

@ArthurSonzogni

I tried to find those libs for mac so I ended up installing boost and ossp-uuid, they're supposed to be the same but in brew. (I could be wrong though)

Still had the same result :'(

I think I'll have to wait for a binary.

Indeed. I get the same error on Mac: https://github.com/ArthurSonzogni/Diagon/runs/4609385209?check_suite_focus=true

I will take a look.
