linux编译ruby1.8.7 出现OPENSSL错误

安装ruby-1.8.7出现编译错误.如下:
ossl_pkey_ec.c:815: error: ‘EC_GROUP_new_curve_GF2m’ undeclared (first use in this function)
ossl_pkey_ec.c:815: error: (Each undeclared identifier is reported only once
ossl_pkey_ec.c:815: error: for each function it appears in.)
make[1]: *** [ossl_pkey_ec.o] Error 1
make[1]: Leaving directory `/home/vagrant/ruby-1.8.7-p357/ext/openssl'
make: *** [all] Error 1

解决方法如下:
vi ~/install/ruby-1.8.7-p357/ext/openssl/ossl_pkey_ec.c
改下面4个地方,+号是添加的:

method = EC_GFp_mont_method();
} else if (id == s_GFp_nist) {
method = EC_GFp_nist_method();
+
#if !defined(OPENSSL_NO_EC2M)
} else if (id == s_GF2m_simple) {
method = EC_GF2m_simple_method();
+
#endif
}
if (method) {
if (id == s_GFp) {
new_curve = EC_GROUP_new_curve_GFp;
+
#if !defined(OPENSSL_NO_EC2M)
} else if (id == s_GF2m) {
new_curve = EC_GROUP_new_curve_GF2m;
+
#endif
} else {
rb_raise(rb_eArgError, "unknown symbol, must be :GFp or :GF2m");
}

改好了之后,再重新编译,如下:
./configure --prefix=/usr/local/ruby
make
make install
然后再查看ruby版本号:
/usr/local/ruby/bin/ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [x86_64-linux]

好了,问题解决.
