I know the OS is a bit old, but thought I?d better upgrade OpenSSL on it in now. To configure I used: ./Configure --prefix=/usr/local shared darwin64-x86_64-cc Running make gives lots of errors like this: cc -I.. -I../.. -I../modes -I../asn1 -I../evp -I../../include -fPIC -fno-common -DOPENSSL_PIC -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -arch x86_64 -O3 -DL_ENDIAN -Wall -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_MONT5 -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DMD5_ASM -DAES_ASM -DVPAES_ASM -DBSAES_ASM -DWHIRLPOOL_ASM -DGHASH_ASM -DECP_NISTZ256_ASM -c -o md5-x86_64.o md5-x86_64.s ar r ../../libcrypto.a md5_dgst.o md5_one.o md5-x86_64.o /usr/bin/ranlib: file: ../../libcrypto.a(ebcdic.o) has no symbols /usr/bin/ranlib: file: ../../libcrypto.a(fips_ers.o) has no symbols /usr/bin/ranlib ../../libcrypto.a || echo Never mind. /usr/bin/ranlib: file: ../../libcrypto.a(ebcdic.o) has no symbols /usr/bin/ranlib: file: ../../libcrypto.a(fips_ers.o) has no symbols making all in crypto/sha? before ending: x86_64-mont.s:957:2: error: invalid instruction mnemonic 'adoxq' adoxq %r15,%r10 ^~~~~ x86_64-mont.s:959:2: error: invalid instruction mnemonic 'adcxq' adcxq %rax,%r10 ^~~~~ x86_64-mont.s:960:2: error: invalid instruction mnemonic 'adoxq' adoxq %r15,%r11 ^~~~~ x86_64-mont.s:962:2: error: invalid instruction mnemonic 'adcxq' adcxq %rax,%r11 ^~~~~ x86_64-mont.s:963:2: error: invalid instruction mnemonic 'adoxq' adoxq %r15,%r12 ^~~~~ x86_64-mont.s:966:2: error: invalid instruction mnemonic 'adcxq' adcxq %rax,%r12 ^~~~~ x86_64-mont.s:967:2: error: invalid instruction mnemonic 'adoxq' adoxq %r15,%r13 ^~~~~ x86_64-mont.s:972:2: error: invalid instruction mnemonic 'adcxq' adcxq %rax,%r13 ^~~~~ x86_64-mont.s:973:2: error: invalid instruction mnemonic 'adoxq' adoxq %rbp,%r15 ^~~~~ make[2]: *** [x86_64-mont.o] Error 1 make[1]: *** [subdirs] Error 1 make: *** [build_crypto] Error 1 This worked with 1.0.1 versions. Any suggestions? Thanks, James. -------------- next part -------------- A non-text attachment was scrubbed...
