These problems in the configure script seem to stem from misuse of autoconf
|
||
|
|
features. Something about the way the checks for libusb are written prevents
|
||
|
|
autoconf from being able to determine later that the headers and functions
|
||
|
|
exist so move the checks for headers and functions before the libusb check.

Fix:

|
|
|
||
|
|
error: implicitly declaring library function 'malloc' with type 'void *(unsigned long)' [-Werror,-Wimplicit-function-declaration]
|
||
|
|
|
||
|
|
Upstream has already fixed this problem by moving the code that uses malloc
|
||
|
|
from atmel.c to intel_hex.c which already includes <stdlib.h>.
