If it says "command not found", you don't. Otherwise, you do. Technically, that is testing to see if gcc is in his PATH. Typing gcc could fail even if it is installed. Ernest: It gave me 'no input files'. Does this mean its installed. I'm assuming yes? Also try gcc -v to get the installed version number. You could just try to see if a gcc executable is present.
Better with whereis gcc or which gcc. If someone messed up the. I, for one, have gcc You can use "locate gcc" to find all filenames with gcc in them. Xenoactive Xenoactive 4 4 silver badges 6 6 bronze badges. Gaff On Terminal type gcc -v You will get something like below Using built-in specs.

On personal computers, any subdirectory of your HOME directory should do. Note that once you have built Sage by running make , as described below , you will not be able to move or rename its directory without likely breaking Sage. This creates a directory sage-x. Optional: Set various other environment variables that influence the build process; see Environment variables. Those variables defining your compilers can be set at configuration time and their values will be recorded for further use at runtime. Those initial values are over-ridden if Sage builds its own compiler or they are set to a different value again before calling Sage.
Note that some packages will ignore the compiler settings and use values deemed safe for that package on a particular OS. Optional: Run the configure script to set some options that influence the build process.
Therefore the installation hierarchy must be writable by the user. This compiles Sage and all its dependencies. Beware of this convenience when compiling for macOS. Note that you do not need to be logged in as root, since no files are changed outside of the sage-x. In fact, it is inadvisable to build Sage as root , as the root account should only be used when absolutely necessary and mistyped commands can have serious consequences if you are logged in as root. There has been a bug reported see trac ticket in Sage which would have overwritten a system file had the user been logged in as root.
Depending on the age and the architecture of your system, it can take from a few tens of minutes to several hours to build Sage from source. On really slow hardware, it can even take a few days to build Sage. If the build of Sage fails, you will see a message mentioning which package s failed to build and the location of the log file for each failed package. It would also be helpful to include the type of operating system Linux, macOS, Solaris, OpenSolaris, Cygwin, or any other system , the version and release date of that operating system and the version of the copy of Sage you are using.
There are no formal requirements for bug reports — just send them; we appreciate everything. See Make targets for some targets for the make command, Environment variables for additional information on useful environment variables used by Sage, and Building the notebook with SSL support for additional instruction on how to build the notebook with SSL support.

Note that Sage should take well under a minute when it starts for the first time, but can take several minutes if the file system is slow or busy. Since Sage opens a lot of files, it is preferable to install Sage on a fast filesystem if possible. Just starting successfully tests that many of the components built correctly. Note that this should have been already automatically tested during the build process. If the above is not displayed e. Optional, but highly recommended: Test the install by typing.
This runs most examples in the source code and makes sure that they run exactly as claimed. To test all examples, use. Some optional examples will therefore likely fail. Testing the Sage library can take from half an hour to several hours, depending on your hardware.

On slow hardware building and testing Sage can even take several days! Optional: Check the interfaces to any other software that you have available. Note that each interface calls its corresponding program by a particular name: Mathematica is invoked by calling math , Maple by calling maple , etc. Sage inserts this directory at the front of your PATH , so your script may need to use an absolute path to avoid calling itself; also, your script should pass along all of its arguments.
How does one install GCC on a Mac? - Apple Community
For example, a maple script might look like:. Now simply typing sage from any directory should be sufficient to run Sage. If you do this, make sure you edit the line:. It is best to edit only the copy, not the original. You can also make a KDE desktop icon with this line as the command under the Application tab of the Properties of the icon, which you get my right clicking the mouse on the icon.
For example, put something similar to the following line in your. Having done so, quit your terminal emulator and restart it. Now typing sage within your terminal emulator should start Sage. Optional: Install optional Sage packages and databases. You also may want to use OpenID for user authentication. Note that these commands require Internet access. The procedure is as follows again, with a computer connected to the Internet.
Starting from a fresh Sage tarball:.
Some systems may encounter this problem frequently enough to make building or testing difficult. If executing the above scripts or directly calling rebaseall does not solve rebasing issues, deleting the system-wide database and then regenerating it from scratch, e. The make command is pretty smart, so if your build of Sage is interrupted, then running make again should cause it to pick up where it left off.
The make command can also be given options, which control what is built and how it is built:. Sage uses several environment variables to control its build process. Note though that setting MAKE , as described below, can significantly speed up the process. Building Sage involves building about packages, each of which has its own compilation instructions. The Sage source tarball already includes the sources for all standard packages, that is, it allows you to build Sage without internet connection. The git repository, however, does not contain the source code for third-party packages.
Instead, it will be downloaded as needed Note: you can run make download to force downloading packages before building. Package downloads use the Sage mirror network, the nearest mirror will be determined automatically for you. This is influenced by the following environment variable:. Note that Sage will search the directory. Note that not all Sage packages e.
