13468 :: Nimble task for build fails but "equivalent" command line works

• hmf (orginal) [2025-10-19T13:49:07+02:00] view original

  Hello,

  I am a Nim-lang newbie and have setup a project using Nimble. If I use the command line:

  
  nimble build -d:glfwStaticLib --verbose src/tutorial_glfw3/minimal.nim tutorial_glfw3/minimal
  Run

  Then compilation works fine:

  However, I have set up the following task:

  
  task buildAll, "Build all binaries":
    selfExec("build -d:glfwStaticLib src/tutorial_glfw3/minimal.nim tutorial_glfw3/minimal")
  Run

  and when I execute the command:

  
  $ nimble --verbose buildAll
  Run

  I get:

  I see that the --path is not added to the command line generated by the Nimble task (in fact none of the other nimble elements are added to the command line). I am using VScode with the Nim extension, and the IDE too complains it cannot load the file. How should one define such a build task? I had assumed the requires of the nimble script would handle this automatically. Note that I am on an Ubuntu OS.

  TIA

  /home/hmf/.choosenim/toolchains/nim-2.2.4/bin/nim build -d:glfwStaticLib src/tutorial_glfw3/minimal.nim tutorial_glfw3/minimal [OSError]

  selfExec() runs command with nim, but you need nimble, so instead use:

  
  task buildAll, "Build all binaries":
    exec("nimble build -d:glfwStaticLib src/tutorial_glfw3/minimal.nim tutorial_glfw3/minimal")
  Run

  Also, you can setup paths for nim compiler by running nimble setup in project directory.

  @janAkali Thank you. Solved my issue. Apologies, but I don't seem to able to flag your reply as the correct answer.

  As for the simble setup command I am re.reading the Nimble docs on this.

  Thanks again.
