来自IPKG-ng的Ruby rbconfig.rb文件有问题

时间：2016-06-01 17:21:33

标签： ruby gcc rubygems

我有一个Synology NAS（DS214 +），我使用optware-ng（https://github.com/Optware/Optware-ng）来安装ruby。

Ruby附带'gem'来管理ruby gems并且我能够使用gem安装简单的gem，但是当尝试安装bcrypt或nokogiri或机械化时，我遇到错误，因为这些gem需要使用本机编译gcc等失败了。

我发现问题出在 rbconfig.rb 文件中，该文件应该引用正确的gcc二进制文件，as，dl等。

然而，它指的是不正确的硬编码路径，例如：

CONFIG["CC"] = "/home/jenkins/Optware-ng/buildroot-armeabihf/toolchain/buildroot-armhf-linux-3.2.66-glibc-5.3.0/bin/arm-buildroot-linux-gnueabihf-gcc"

虽然它应该是：

CONFIG["CC"] = "/opt/bin/gcc"

即使修改了这些路径，它仍然无法工作，尽管它现在至少可以编译某些部分。我仍然在查看这个配置文件中的一些内容。

以下是错误的配置文件。

# changes made to this file will be lost the next time ruby is built.

我知道的问题是尝试通过以下方式安装bcrypt：

gem install bcrypt

是二进制'ld'无法找到必要的库（可能再次出现路径问题）

linking shared-object bcrypt_ext.so
/volume1/@optware/bin/../lib/gcc/arm-buildroot-linux-gnueabihf/5.3.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: cannot find -lgcc_s

图书馆出现在

/opt/lib/libgcc_s.so.1

是否有人注意到配置文件中的任何其他问题，或者是否有人可以提供有效的配置文件，以便我可以将其与我的错误进行比较。

答案 0 :(得分：0)

如前所述，我不得不用正确的链接替换硬编码链接。

以下是默认安装ipkg：

之后仍然存在一个问题，即它没有找到-lgcc_s（显然是libgcc_s.so）的错误。但我确实找到了库/opt/lib/libgcc_s.so.1。所以我可以通过以下方式解决问题：

ln -s /opt/lib/libgcc_s.so /opt/lib/libgcc_s.so.1]

在此之后，安装正常使用：

gem install nokogiri
gem install mechanize
gem install bcrypt
