Platformio can't see correct working directory

[vatrat]

This is related to #10. I am also using spacemacs. No matter what I try, I can't get platformio-mode to use the correct directory when building. It always uses ~/code, not ~/code/embedded/esp32/test/ (~/code/embedded/esp32/test/src/ is the current directory). I tried using cd to correct the directory of the main.cpp buffer but it had no effect. I then went to the PIO buffer and changed the directory, but it had no effect. I tried the line (add-to-list 'projectile-project-root-files "platformio.ini") in my .spacemacs, but it tells me Error in dotspacemacs/user-config: Symbol’s value as variable is void: projectile-project-root-files. I used describe-variable to look at default-directory and it told me this:

default-directory is a variable defined in ‘C source code’.
Its value is "/home/vatrat/code/embedded/esp32/test/src/"
Local in buffer main.cpp; global value is nil

  Automatically becomes permanently buffer-local when set.
  This variable is safe as a file local variable if its value
  satisfies the predicate ‘stringp’.

However, when I run C-c i b or C-c i u from the same file PIO shows

-*- mode: platformio-compilation; default-directory: "~/code/" -*-
PIOCompilation started at Mon Dec  4 19:16:17

platformio -f -c emacs run 
Error: Please setup environments in `platformio.ini` file

PIOCompilation exited abnormally with code 1 at Mon Dec  4 19:16:18

This is coming quite a while later, but one workaround I've found is to create an empty .projectile file in the root directory. By using customize-group to look at the projectile variable, it seems that putting the add-to-list line in my .spacemacs file isn't working to change the variable. I'm not currently familiar enough with emacs to see why, probably something to do with loading order.

Hi @vatrat

I apologize for the complete silence on this. I will have to go look into getting email notifications turned on for issues.

I will try to have a look at this in the next few days; In the meantime perhaps have a look at my Emacs config to see if you may have something set up different.

Some sections of interest:

• Projectile
• C++ and PlatformIO-Mode

same problem for me: emacs-26.3 Fedora 31 PlatformIO, version 4.3.2a1 create an empty .projectile file in the root directory solve the problem

I think this might be caused by projectile looking for a git repository. I've had a similar problem before where projectile wouldn't recognize my project until I ran git init in the root

For me also working with git init

Better late than never, but seems like git init is the key here.
