| # Notes | |
| # | |
| # --enable-shared --enable-threads=posix --enable-__cxa_atexit: | |
| # These parameters are required to build the C++ libraries to published standards. | |
| # | |
| # --enable-clocale=gnu: | |
| # This parameter is a failsafe for incomplete locale data. | |
| # | |
| # --disable-multilib: | |
| # This parameter ensures that files are created for the specific | |
| # architecture of your computer. | |
| # This will disable building 32-bit support on 64-bit systems where the | |
| # 32 bit version of libc is not installed and you do not want to go | |
| # through the trouble of building it. Diagnosis: "Compiler build fails | |
| # with fatal error: gnu/stubs-32.h: No such file or directory" | |
| # | |
| # --with-system-zlib: | |
| # Uses the system zlib instead of the bundled one. zlib is used for | |
| # compressing and uncompressing GCC's intermediate language in LTO (Link | |
| # Time Optimization) object files. | |
| # | |
| # --enable-languages=all | |
| # --enable-languages=c,c++,fortran,go,objc,obj-c++: | |
| # This command identifies which languages to build. You may modify this | |
| # command to remove undesired language | |

N.B. On some versions of Debian, the lines added to .bashrc at the end of the script are not written exactly correctly and may need manual correction.

This also borrows a little bit of clean up code from "ryans" here: https://community.webfaction.com/questions/20158/installing-gcc-54
