Linux Set up

[2Guz]

I'm following the steps provided on this page, but I have reached a part that I'm stuck on. https://github.com/ROBOTIS-Leon/test2/wiki/3.2.2-Linux I navigated to the linux64 directory and typed the command "make" and received an error. I then typed "make clean" to try and fix the issue, but when I typed "make" again, the same error appeared.

Here is the error I have:

Hi!
I'm so sorry for the inconvenience.
The main reason of what you said is that intN_t data types are already predefined in the linux platform, so the error was occurred by double definition on robotis_def.h. Hence, you can solve it by putting #if defined(_WIN32) || defined(_WIN64) and #endif near the type definition of intN_ts (just wrap three of them), like:

#if defined(_WIN32) || defined(_WIN64)
typedef char                int8_t;
typedef short int           int16_t;
typedef int                 int32_t;
#endif

I thought that this had been updated in the DynamixelSDK-master but it wasn't. It was absolutely my fault. Besides, after solving that problem, you will face different kind of errors so do your work on different way.

I recommend you to use the source of DynamixelSDK-develop rather than DynamixelSDK-master for now. Kinds of problems in the code are solved (as I know), and I will merge the DynamixelSDK-master when my work is finished, so don't waste your time.

Any other questions, don't hesitate to ask me.

Thank you
