Erlang安装和“ /usr/local/ssl/lib/libcrypto.a：无法读取符号：错误值”

Question

我正在尝试在Linux机器Red Hat Enterprise Linux Server 6.6版上安装RabbitMQ（3.6.1）。要安装rabbitMQ，首先我从源代码（otp_src_R16B03）安装了Erlang R16B03版本，然后执行以下命令

wget http://www.erlang.org/download/otp_src_R16B03.tar.gz
tar xvfz /usr/tmp/otp_src_R16B03.tar
cd otp_src_R16B03
LANG=C; export LANG
./configure --with-ssl=/usr/bin

我收到如下所示的消息：

*********************************************************************

虽然我继续进行make＆make install，但是在启动Rabbitmq服务器时出现以下错误

sbin/rabbitmq-server

取得讯息

探索了多种解决方案后，我了解到我需要安装最新的Openssl并提供新安装的openssl的路径。

我从源代码安装了Openssl并与-fPIC一起安装

wget https://www.openssl.org/source/openssl-1.0.2.tar.gz
tar xvfz /usr/tmp/openssl-1.0.2.tar.gz
cd /usr/tmp/openssl-1.0.2
./config -fPIC
make 
make install 

现在，新的openssl安装在bin / local / ssl位置，并且我使用以下配置重新安装了Erlang

export PATH="/usr/local/ssl/bin:$PATH”
export CFLAGS=-fPIC
cd /usr/tmp/otp_src_RB1603
LANG=C; export LANG
./configure --with-ssl=/usr/local/bin
make
make install

现在我得到了错误

export PATH="/usr/local/ssl/bin:$PATH”
export CFLAGS=-fPIC
cd /usr/tmp/otp_src_RB1603
LANG=C; export LANG
./configure --with-ssl=/usr/local/bin
make
make install

我无法解决此错误，没有任何建议。。请注意，我以root用户身份使用机器

/usr/bin/ld: /usr/local/ssl/lib/libcrypto.a(rsaz_exp.o): relocation R_X86_64_32 against `.rodata'
can not be used when making a shared object; recompile with -fPIC
/usr/local/ssl/lib/libcrypto.a: could not read symbols: Bad value**
collect2: ld returned 1 exit status

您需要使用该shared选项构建 OpenSSL。对于 64 位 Intel 机器，可能类似于以下内容。

/usr/bin/ld: /usr/local/ssl/lib/libcrypto.a(rsaz_exp.o): relocation R_X86_64_32 against `.rodata'
can not be used when making a shared object; recompile with -fPIC
/usr/local/ssl/lib/libcrypto.a: could not read symbols: Bad value**
collect2: ld returned 1 exit status

enable-ec_nistp_64_gcc_128使 EC Diffie-Hellman 速度提高 2 到 4 倍，但它有一些限制。您可以在 64 位 Intel 机器上使用它。另请参阅编译和安装 | 在 OpenSSL wiki 上配置选项。

另外，请确保make dcleanOpenSSL 1.0.2 及以下版本；或make distclean适用于 OpenSSL 1.1.0 及更高版本。否则，即使更改选项后，一些旧配置仍然存在。
