+Subject: libscrypt: FTBFS on big endian architecture
+Date: Wed, 30 Oct 2013 00:09:08 +0100
+
+Version: 1-2
+Severity: important
+Tags: upstream patch
+Justification: fails to build from source
+
+libscrypt fails to build from source on big endian architectures, due
+to testsuite errors:
+
+| TEST EIGHT: Create an MCF format output
+| TEST EIGHT: SUCCESSFUL, calculated mcf
+| $s1$0e0801$U29kaXVtQ2hsb3JpZGU=$cCO9yzr9c0hGHAbNgf046/2o+7qQT44+qbVD9lRdofLVQylVYT8Pz2LUlwUkKpr55h6F3A1lHkDfzwF7RVdYhw==
+| TEST NINE: Password verify on given MCF
+| TEST NINE: FAILED, hash failed to calculate
+| make[1]: *** [check] Error 1
+
+This is due to code in modp_b64.c which is endianness dependent. A big
+and a little endian version of the code are provided, but the selection
+mechanism is supposed to be done by modifying the source code, which is
+not really compatible with a Debian source package. This leads to the
+little endian code to be always used.
+
+The patch below fixes the problem by getting the endianness from
+<endian.h>.
+
+It has been tested on mips, powerpc and s390x.
