[linux编译c程序]linux编译ruby1.8.7错误问题解决办法

【www.bbyears.com--ruby】

今天同事要求在测试机上安装ruby和rails的时候,居然安装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:

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]
