Question

我正在尝试在Red Hat上安装单独版本的Openssl 1.0.1k。我首先尝试使用Centos，没有任何实际问题。

在发生此错误之前，我执行了以下操作：

yum install -y libxml2 libxml2-devel libxslt libxslt-devel    #not sure if this actually helped with my errors. 
./config --prefix=/data/home/jboss/openssl_1.0.1/usr         \
         --openssldir=/data/home/jboss/openssl_1.0.1/etc/ssl
# missing include files. 
vi ~/.bash_profile
C_INCLUDE_PATH=/usr/lib/bcc/include/
CPLUS_INCLUDE_PATH=/usr/lib/bcc/include/
export C_INCLUDE_PATH
export CPLUS_INCLUDE_PATH
LANG=en_US           # make was giving accented a special characters. This fixed. I would set it back once I fixed to en_US.UTF-8. 
vi /usr/lib/bcc/include/asm/limits.h
define INT_MAX              2147483647

毕竟，我得到以下内容：

任何见解都会有所帮助。

{p> offsetof定义在<stddef.h>中，由ec_asn1.c和rand_egd.c使用。

但是，ec_asn1.c和rand_egd.c不包括<stddef.h>：

$ cd openssl-1.0.1
$ find . -iname ec_asn1.c
./crypto/ec/ec_asn1.c
$ cat crypto/ec/ec_asn1.c | grep stddef

您应该打开ec_asn1.c和rand_egd.c，然后添加#include <stddef.h>。

针对此问题针对OpenSSL提交了一个错误：Bug 3684: Missing <stddef.h> for source files using offsetof。您可以在RT Tracker中查看状态。用username = guest，password = guest登录。

以下是我正在处理的机器的定义，以备不时之需：

#if defined(__GNUC__) && (__GNUC__ == 3 && __GNUC_MINOR__ >= 5 || __GNUC__ > 3)
#ifndef __offsetof      /* Deprecated: for source compatibility only */
#define __offsetof(type, field) __builtin_offsetof(type, field)
#endif
#define offsetof(type, field) __builtin_offsetof(type, field)
#else /* ! (gcc >= 3.5) */
#ifndef __offsetof      /* Deprecated: for source compatibility only */
#define __offsetof(type, field) ((size_t)(&((type *)0)->field))
#endif
#define offsetof(type, field) ((size_t)(&((type *)0)->field))
#endif /* (gcc >= 3.5) */

犯错误 - ec_asn1.o - ec_asn1.c：201：错误：在＆＃39; X9_62_PENTANOMIAL＆＃39;之前的预期表达式
