# sage installation error

I get the following error while installing Sage :

```
checking for gcc option to accept ISO C99... unsupported
checking for sqrt in -lm... no
configure: This system has no maths library installed.
configure: error: Exiting, since a maths library was not found.
```

Hello! Thanks for reporting this. We need a bit more detail to help. What is your operating system? (Ubuntu xx.yy? Mac OS X 10.x.y?) What version of Sage are you trying to install, where did you download it from and what command did you run?

I m using BOSS linux (5.1) -Debian based latest sage version binaries downloaded from sagemath make command gives that error

I have installed all prerequisites for sage but make command does not link maths library in gcc.

@jsamadhan0: you mean latest Sage source tarball, not binaries, right? If you download binaries, you don't have to run make, these should already be working. If you download source, then you compile it with 'make' to get a working Sage.

sorry for the mistake.I downloaded source tar.lmza and compiled it using make command
