Question

使用以下命令在Windows上的MSys 1.0中配置相当简单的OpenSSL 1.0.2l。

./Configure no-zlib no-shared no-dso no-krb5 no-camellia no-capieng no-cast no-cms no-dtls1 no-gost no-gmp no-heartbe
ats no-idea no-jpake no-md2 no-mdc2 no-rc5 no-rdrand no-rfc3779 no-rsax no-sctp no-seed no-sha0 no-static_engine no-whi
rlpool no-rc2 no-rc4 no-ssl2 no-ssl3 mingw

运行configure后，运行make depend会出现以下错误。

In file included from dh_kdf.c:58:0:
../../include/openssl/cms.h:61:4: error: #error CMS is disabled.
 #  error CMS is disabled.

这似乎很愚蠢，当然我告诉它没有cms。任何想法除了删除no-cms之外还要做什么？

看来OPENSSL_NO_CMS是一个有效的预处理器宏。它用于大多数地方，但不是所有地方。使用OPENSSL_NO_CMS表示no-cms是有效选项。（我似乎记得它一直是，但最好确保）。

现在打开OpenSSL问题跟踪器：Issue 3867, Configuring with no-cms and "undefined reference to CMS_SharedInfo_encode"。

与此同时：

$ git diff crypto/dh/dh_kdf.c
diff --git a/crypto/dh/dh_kdf.c b/crypto/dh/dh_kdf.c

 /* Key derivation from X9.42/RFC2631 */

但是，由于使用了dh_sharedinfo_encode（见crypto/dh/dh_kdf.c），CMS_SharedInfo_encode中出现了更大的问题：

gcc -I.. -I../.. -I../modes -I../asn1 -I../evp -I../../include  -DOPENSSL_THREADS -D_REENTRANT -m64 -DL_ENDIAN -O3 -Wall -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_MONT5 -DOPENSSL_BN_ASM_GF2m -DRC4_ASM -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DMD5_ASM -DAES_ASM -DVPAES_ASM -DBSAES_ASM -DGHASH_ASM -DECP_NISTZ256_ASM   -c -o dh_kdf.o dh_kdf.c

     derlen = CMS_SharedInfo_encode(pder, &atmp, pukm_oct, outlen);
              ^~~~~~~~~~~~~~~~~~~~~

导致：

../libcrypto.a(dh_kdf.o): In function `DH_KDF_X9_42':
dh_kdf.c:(.text+0x180): undefined reference to `CMS_SharedInfo_encode'
collect2: error: ld returned 1 exit status

看起来OpenSSL团队需要关注这个问题。

带有no-cms选项的OpenSSL抱怨没有使用make依赖的CMS
