[Qemu-devel] [Bug 1347555] Re: qemu build failure, hxtool is a bash script, not a /bin/sh script

[Thomas Huth]

Closing this ticket, as it was rather a problem with the non-posix-
compliant shell and not the QEMU build system.

Title:
  qemu build failure, hxtool is a bash script, not a /bin/sh script

Status in QEMU:
  Won't Fix

Bug description:
  hxtool (part of the early build process) is a bash script.  Running it
  with /bin/sh yields a syntax error on line 10:

   10             STEXI*|ETEXI*|SQMP*|EQMP*) flag=$(($flag^1))

  $(( expr )) is a bash extension, not part of /bin/sh.

  Note that replacing the sh in the first line in hxtool with /bin/bash
  does not help, because the script is run manually from the Makefile
  with sh:

  154         $(call quiet-command,sh $(SRC_PATH)/scripts/hxtool -h < $<
  > $@,"  GEN   $@")

  The fix is to change those lines to

  154         $(call quiet-command,bash $(SRC_PATH)/scripts/hxtool -h <
  $< > $@,"  GEN   $@")

  (there are five or so).
