Source: dieharder Version: 3.31.1-8 Tags: patch upstream User: [email protected] Usertags: ftcbfs
dieharder fails to cross build from source, because its configure script uses AC_RUN_IFELSE to discover the endianess. The check included in autoconf, AC_C_BIGENDIAN, can be performed without running host code. Using it results in better portability and less code. Please consider applying the attached patch. Helmut
