Therefore, if you have defined any environment variables that override default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting or modifying them when building GCC. This is an older release of GCC which we are going to install for the purpose of compiling the Linux kernel in . This version is recommended by the kernel developers when you need absolute stability. Later versions of GCC have not received as much testing for Linux kernel compilation. Using a later version is likely to work, however, we recommend adhering to the kernel developer's advice and using the version here to compile your kernel. We don't install the C++ compiler or libraries here. However, there may be reasons why you would want to install them. More information can be found at . We'll install this older release of GCC into the non-standard prefix of /opt so as to avoid interfering with the system GCC already installed in /usr .
