Cannot install KORTEX API

[TomSAVU]

Description

I'm receiving errors when trying to build in CLion

Version

KortexAPI : 2.5.0

Kortex Device : Windows 10 64 bit

Steps to reproduce

Performed all the steps in https://www.youtube.com/watch?v=JparQ69LMzY&list=PLz1XwEYRuku5rZjJWBr6SDi93jgWZ4FHL&index=3

Any other information

The error I receive when trying to build is

Hi @TomSAVU,

This is not an error with our API, it seems like you are not using the C++ std library correctly. Maybe you are using an older or a more recent compilator?

We provide instructions on how to build and setup your environment : https://github.com/Kinovarobotics/kortex/tree/master/api_cpp/examples

If you follow these instructions and tell me where you get stuck, I could maybe help you more.

There is very little I can do to help you if you are using Clion, that I do not use, and it doesn't work.

Best,
Felix

Thanks Felix,
I'm using a version of CLion installed today, because this is what I saw in
https://www.youtube.com/watch?v=JparQ69LMzY&list=PLz1XwEYRuku5rZjJWBr6SDi93jgWZ4FHL&index=3
and I thought it's recommended.
I will try with the instructions you recommended and using Visual Studio and I will come back.

Hi @felixmaisonneuve

In Visual Studio 2022 it shows me 25 similar errors, first one in hash.h line 241, which is
struct hash : public GOOGLE_PROTOBUF_HASH_COMPARE {

There is a Key before {, but can't write it here

The first error is
C2143 syntax error: missing a ',' before '<'

Next error is
C2039 'hash compare': is not a member of 'std'

[felixmaisonneuve]

For you error in CLion, it looks like this issue : https://stackoverflow.com/questions/4798936/numeric-limits-was-not-declared-in-this-scope-no-matching-function-for-call-t

Try adding #include <memory> in cxxopts.hpp in thirdParty folder

For your VisualStudio errors, I do not understand what you are talking about. hash.h is not a file in our repository and GOOGLE_PROTOBUF_HASH_COMPARE is not present in any file.

What version of cmake, make, gcc and g++ are you using?
What commit are you using?

[TomSAVU]

I'm using Microsoft Visual Studio Community 2022 (64-bit) - Version 17.6.2.
Stopped following the install guide from YouTube and I used the native CMake.
Although I disabled Conan in the CMake settings, I was still receiving error messages.
I've commented all the references to Conan in conan.cmake and CMake generation finishes without errors.
When trying to build, there are errors like "Cannot open include file: 'SessionManager.h': No such file or directory" in 01-api_creation.cpp or "Cannot open include file: 'BaseClientRpc.h': No such file or directory" in 01-gripper_command.cpp

[felixmaisonneuve]

Did you download the C++ API zip archive msvc 2019 mingw (make sure to take the one for your architecture).

If you disabled conan and you are trying to build manually, the API must be located at the correct path in the kortex_api folder
https://github.com/Kinovarobotics/kortex/tree/master/api_cpp/examples#not-using-conan

This is where it will look for the library by default
https://github.com/Kinovarobotics/kortex/blob/6f557a8c65d5b5d8e83bf4966604788a05713658/api_cpp/examples/CMakeLists.txt#L171

Hi, @felixmaisonneuve I am also getting the same issue as @TomSAVU when I build any of the examples. The following errors coming from the hash.h file found in the Kortex_Api in "./kortex_api/include/google/stubs/hash.h":

C2143: syntax error: missing ',' before '<' Line 241
C2039 'hash_compare': is not a member of 'std'
...

And a few more. I have downloaded the msvc 2019 API archive mentioned in your comment above and followed all the steps in the C++ guide. The CMake generation completes without error and it shows it is using the right folder for the kortex_api but building any example fails.

Would you have any ideas? Let me know if you need more information.
