我尝试在Amazon Lightsail示例（Amazon Linux 2017.09.1）上运行的R中安装rJava包。我一直收到gcc找不到libgomp.spec的错误
我在**/usr/lib/gcc/x86_64-amazon-linux/6.4.1/libgomp.spec**中找到了这个文件，并且尝试设置一个指向它的符号链接，但是我还没有能够找到符号链接的位置，这样gcc就可以找到它。例如，这似乎不起作用：

ln -s /usr/lib/gcc/x86_64-amazon-linux/6.4.1/libgomp.spec /usr/local/lib64/libgomp.spec

有没有人知道把符号链接放在哪里，以便gcc可以找到它？在这个输出中可能有一个我不明白的提示：
