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.
