9419 :: Info about gcc compiler options used by nim

  Hi,

  I would like to have more info about performing the compiling process step from C to binary manually.

  Starting from the ~/nimcache/ folders where I have the source C files created by nim, what options are given to C compiler? What folders should be included that contain other C sources?

  My goal is simply to manually reproduce the second compile step, so would be fine any hint or link to documentation or source code. Thanks!

  The command passed to the C compiler/linker is written in a comment at the top of the main C file in the nimcache dir and the .json file in the same directory has lists of all source and objects files.

  You could run a nim compile with the --listCmd option to see the command lines for the compiles and links that nim executes. You may need to remove cached compiles (check ~/.cache/nim/ for directories beginning with the relevant program name)

  Cool! Thanks. I see that also the .json file seems to contain all build and link instructions. This is really nice, gives a lot of insights.

  Also this is a nice way to understand what is inside... thanks!

  From https://nim-lang.org/docs/nimc.html

  You can pass --genScript:on and it will > generate a compile script (in the 'nimcache' subdirectory named 'compile_$$project$$scriptext'), and a '.deps' file containing the dependencies; implies --compileOnly it will create a shell script in the nimcache directory that contains all the
