Error found by spectre.
    ERROR (SPECTRE-15): Unable to run circuit preprocessor (/lib/cpp).
        No such file or directory.

spectre terminated prematurely due to fatal error.

这列提示找不到/lib/cpp 但是不知道这个文件该在哪里找

已解决
方法：
According to http://support.cadence.com Article 1841055, this error means that Spectre couldn't find the c pre-processor file cpp at /lib/cpp. This can be resolved by reinstalling the operating system component which will install all the c language utilities, including the c pre-processor cpp that the Spectre simulator requires.

yum -y install gcc
yum -y install gcc-c++
