8638 :: Nim stopped working on my Mac M1 : string.h missing (problem with homebrew or Xtools)?

  Hi,

  I am using a Mac M1 (silicon), I have Xtools installed.

  It runs Mac OSX Monterey

  I had installed Nim with brew

  "arch -arm64 brew install nim"

  And it worked OK until now.

  Nim does not work any more today, however: I get error messages of the kind:

  
  Error: execution of an external compiler program 'clang -c  -w -ferror-limit=3   -I/opt/homebrew/Cellar/nim/1.6.0/nim/lib -I/Users/sergehulne/Documents/code/Nim/tst_1 -o /Users/sergehulne/.cache/nim/main_d/stdlib_io.nim.c.o /Users/sergehulne/.cache/nim/main_d/stdlib_io.nim.c' failed with exit code: 1
  
  
  1 error generated.

  and similar, if I try to reinstall Nim from source: when attempting to run build.h, I get

  
  sergehulne@Serges-Mac-mini csources % sh build.sh
  # OS: macosx
  # CPU: amd64
  clang -w -O3 -fno-strict-aliasing -Ic_code -c c_code/1_2/stdlib_assertions.nim.c -o c_code/1_2/stdlib_assertions.nim.o
  clang -w -O3 -fno-strict-aliasing -Ic_code -c c_code/1_2/stdlib_dollars.nim.c -o c_code/1_2/stdlib_dollars.nim.o
  c_code/1_2/stdlib_dollars.nim.c:7:10: fatal error: 'string.h' file not found
  #include <string.h>
  Run

  Does anybody have a similar issue with Nim / Xcode tools? Has the location of of Xcode tools changed?

  I'm on OSX too and have not experienced this problem.

  Thanks for your answer. I must have done something wrong inadvertently, then.

  No issues on OSX M1 for me. I would reinstall x-code.

  I’m reinstalling it from backup (time machine). I’ll see if it does the trick. I’m not sure if it is the actual content of Xcode which has been modified or if a configuration file (containing environment variables in Xcode or elsewhere) which merely points to said locations is at fault.

  Are you using Monterey?

  I'm on Monterey, yes.

  I reinstalled "Brew" and reinstalled Nim on top of it.

  I guess, I typed a wrong command in brew and messed it up.

  Everything is back to normal. Apologies for the false alarm. Thanks for the hep !
