11 years agouse assert(0) instead of exit(1)
Loic Dachary [Mon, 15 Dec 2014 11:08:37 +0000 (12:08 +0100)]
use assert(0) instead of exit(1)

When a fatal error (unaligned memory etc.) is detected, jerasure
should assert(3) instead of exit(3) to give a chance to the calling
program to catch the exception and display a stack trace. Although it is
possible for gdb to display the stack trace and break on exit, libraries
are not usually expected to terminate the calling program in this way.

add galois_init_default_field error code

galois_init_default_field returns an errno(3) code in case of error
instead of exiting. This is handy when the caller needs to perform
cleanup or error reporting when an error occurs instead of exit(2).

The exit(2) based error handling is preserved in the static
galois_init() function which is used in galois.c instead and is based on
galois_init_default_field to avoid code duplication.

Remove pre-autotools makefiles.

Ignore *.a. (Missed earlier.)

Quiet more warnings.
