我在这里尝试在1.0.1g之前的openssl版本上重新创建Heartbleed错误，因此我选择了openssl 1.0.1f。我安装了AFL-FUZZ，然后安装了openssl。我想借助this和this链接，我已经安装了openssl，但最终却给了我一个奇怪的错误

我运行了openssl version命令，它成功地给了我输出OpenSSL 1.0.1f 6 Jan 2014，因此我认为它已正确安装（不确定如何处理错误）。
现在，下一步就是简单地找到一个使用openssl的代码，我发现了here handshake.c文件。但是，编译失败。 afl-gcc handshake.c libssl.a libcrypto.a -o handshake -I ssl/include -ldl，错误是

请提出如何解决这些错误的建议。
谢谢。
编辑：
所以到目前为止，我所做的是使用root特权安装openssl。我工作了，但给了我很多手动安装错误，即大部分错误看起来像item= expecting something other than a integer。我手动将这些行更改为字符=item 1 -> =item '1'。在更改应用程序和根目录的ssl文件夹后，我终于使它工作了。最终安装看起来像在make and make install之后

The program 'openssl' is currently not installed. You can install it by typing:
apt-get install openssl
现在，我认为安装没有错误，但是我还没有安装openssl，因为它说还没有安装这样的软件包。
请帮助。
答案 0 :(得分：0)
正如我在“编辑帖子”中所添加的，当我以root身份运行安装时，openssl安装中的错误消失了。我使用了以下命令序列；
make clean
./config no-shared no-idea no-mdc2 no-rc5 zlib enable-tlsext
make depend
make && make install
如上面在问题的编辑版本中所讨论的，它给了我.pod文件错误，该错误我一个接一个地解决了（想知道是否有人有更聪明的方法）。
编译后，现在错误仍然与编辑部分相同，将openssl安装路径添加到$ PATH环境变量后，该错误立即得到解决。我在下面的行中添加了.basrc和.profile文件。
export PATH="$PATH:/usr/local/ssl/bin"
现在openssl可以正常工作。
然而，使用openssl编译handshake.c与此命令一起使用
AFL_USE_ASAN=1 afl-gcc handshake.c -lcrypto -lz libssl.a -o handshake -ldl
最后
afl-fuzz -i testcases -o findings -m none -- ./handshake
希望这对将来的Google员工有帮助。
谢谢。
