Type: Bug

Using VS code rev 1.87.2 on ubuntu 6.5.0-25-generic
Code fail to compile the program with bellow Error: Starting build... /usr/bin/gcc -fdiagnostics-color=always -g program.c -o program -lX11 'imlib2-config --cflags'
/usr/bin/ld: cannot find imlib2-config --cflags: No such file or directory collect2: error: ld returned 1 exit status

This is in contrust to a succsfull comilation on a terminal command line as in:
$ gcc -g program.c -o program -lX11 imlib2-config --cflags

My tasks.json args list :
"args": [
"-fdiagnostics-color=always",
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}",
"-lX11",
"imlib2-config --cflags"
]

Can you try

"imlib2-config",
"--cflags"

in tasks.json?

[pugibela]

that is what it looks like now and it works even added another flag...
"-lX11","imlib2-config","--cflags","imlib2-config","--libs"

THANKS
I wish to documentation about these things was a little more detailed and include some examples for these type of uses cases
