I am a complete beginner to using Visual Studio Code and I have no clue what I am doing.
I've searched around (maybe not enough), but I can't find just a simple explanation for someone like me on how to configure the c_cpp_properties.json file that I am redirected to whenever I click on the yellow light bulb next to a line that is underlined with a green squiggle.
I just want to know what to put in the .json to make IntelliSense work properly.
VSCode is very adept at asking the compiler what include paths it is using if you set things up correctly. Part of my project uses a DSP compiler based on GCC, so by adding "-v" to the compiler's flags (I put it in CFLAGS in my Makefile) I was able to see the internal command lines which revealed the "secret" flags being passed to the lower compiler levels. This showed me what "-D" values I needed to add to the "defines" section of my config and, more importantly, that "-isystem" was being used to set the system include directory. I ended up with this in my c_cpp_properties.json:-
{
"configurations": [
{
"name": "CEVA-V15",
"includePath": [
"${workspaceFolder}/**"
],
"defines": [
"CEVAXC323",
"XC323_CEVA"
],
"compilerPath": "/devtools/CEVA-ToolBox/V15/CEVA-XC/cevaxccc",
"cStandard": "gnu11",
"cppStandard": "gnu++14",
"intelliSenseMode": "linux-gcc-arm",
"compilerArgs": [
"-isystem /devtools/CEVA-ToolBox/V15/CEVA-XC/include"
]
}
]
}
