How to make ALE to work with mixed Windows/Cygwin and tricore-gcc?

Question

EDITED: I am running on Windows 10, working with gvim but the overall project is built in Cygwin. The compiler that I am using is tricore-gcc. With lot of pain I managed to build a compile_commands.json file that apparently is working fine (if I use a linter that cannot parse compile_commands.json I immediately have an error on the first #include whereas if I use e.g. clangtidy such an error disappear).

Nevertheless, I tried to mess around with a .c file by removing some ; or } to check if the linter is working, but nothing happens.

I tried to debug a bit by running the commands displayed in ALEInfo from both the Powershell and Cygwin, but I got the following error:

C:\> clang-tidy C:\Project1\Root\software\ComponentONE\src\fileA.c -p C:\Project1\Root
Skipping C:\Project1\Root\software\ComponentONE\src\fileA.c. Compile command not found.

I also tried to adjust the compile_commands.json by changing / with \ (the same for the commands run from the Powershell), I tried to replace tricore-gcc with gcc, etc. but I always got the same error as above.

If I just run

C:\>clang-tidy.exe
clang-tidy.exe: Not enough positional command line arguments specified!
Must specify at least 1 positional arguments: See: C:\Program Files (x86)\LLVM\bin\clang-tidy.exe -help

which means that clang-tidy is recognized.

Finally, if I run the real compiler command:

C:\> tricore-gcc.exe (various flags) C:\Project1\Root\software\ComponentONE\src\fileA.c

from both Powershell or Cygwin I don't get any error.

It follows my ALEInfo

and one extract of my compile_commands.json file:

{
  "directory": ".",
  "command": "c:/Hightec/tricore/v4.6.6.1/bin/tricore-gcc.exe (number of flags) -c software/ComponentONE/src/fileA.c",
  "file": "software/ComponentONE/src/fileA.c"
},

If I run pwd from vim I have C:\Project1\Root

Answer 1

FIXED!

I had to change the compile_commands.json file in this way:

{
  "directory": "C:/Project1/Root",
  "command": "c:/Hightec/tricore/v4.6.6.1/bin/tricore-gcc.exe (number of flags) -c software/ComponentONE/src/fileA.c",
  "file": "software/ComponentONE/src/fileA.c"
},

or in this way

{
  "directory": ".",
  "command": "c:/Hightec/tricore/v4.6.6.1/bin/tricore-gcc.exe (number of flags) -c software/ComponentONE/src/fileA.c",
  "file": "C:/Project1/Root/software/ComponentONE/src/fileA.c"
},

to make it to work. Obviously now there are other issues such as

error: unknown argument: '-fstrict-volatile-bitfields' [clang-diagnostic-error]

but this because the option -fstrict-volatile-bitfields exists for gcc but for clang. I would say problem solved.
