esignal.c:974: error: ‘ARCH’ undeclared (first use in this function)

Error: esignal.c:974: error: 'ARCH' undeclared (first use in this function)



Solution:

1. Open the HTKLib/esignal.c file in a code-friendly text editor. You can use Xcode, or my personal favorite TextMate 2.

2. Find and change the below lines:

   Change Line 974: if (strcmp(architecture, ARCH) == 0) /* native architecture */

   To: if (strcmp(architecture, "darwin") == 0) /* native architecture */

   Change Line 1184: ` architecture = ARCH;`

   To: ` architecture = "darwin";`

3. Now, let's build! Run make all in the terminal window
