What exactly do you mean by that? Code is maintained and was observed to work correctly on either endian system. There are two possibilities: system is not believed endianness or compiler is buggy. If first was case, then even SHA1 test would fail too, so the failure sounds more like compiler bug. Try to drop optimization level: edit Makefile in text editor and replace -O3 with -O0, remove crypto/sha/sha256.o and 'make'. This, dropping optimization level, is suggested in README. > Platform is Renesas SH3E in BIG-endian mode > ( used compiler sh3eb-linux-gcc) ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List openssl-dev@openssl.org Automated List Manager majord...@openssl.org
