Composer is a popular dependency management tool for PHP, created mainly to facilitate installation and updates for project dependencies.
It will check which other packages a specific project depends on and install them for you, using the appropriate versions according to the project requirements. Everything can be installed with the following command:. Composer provides an installerwritten in PHP. Copy the hash from that page and store it as a shell variable:. Then run the command to verify the installer again. Once you have a verified installer, you can continue. Note: If you prefer to have separate Composer executables for each project you host on this server, you can install it locally, on a per-project basis.
Users of NPM will be familiar with this approach. To do this, use the command php composer-setup. This will generate a composer. PHP projects often depend on external libraries, and managing those dependencies and their versions can be tricky. Composer solves that by tracking your dependencies and making it easy for others to install them. The composer.
This is extremely important to keep your project consistent and avoid installing unstable versions that could potentially cause backwards compatibility issues. Composer auto-generates the composer. You can add additional dependencies in the same way, without the need to manually edit this file. The process of using Composer to install a package as dependency in a project involves the following steps:.
The goal of this application is to transform a given sentence into a URL-friendly string - a slug. The number on the top represents how many times the package was installed, and the number on the bottom shows how many times a package was starred on GitHub. You can reorder the search results based on these numbers look for the two icons on the right side of the search bar. Generally speaking, packages with more installations and more stars tend to be more stable, since so many people are using them.
We need a simple string-to-slug converter. The package is a bit further down the page than the screenshot shows. Packages on Packagist have a vendor name and a package name.
You need the namespace in order to require the package in your project.

Now that you know exactly which package you want to install, run composer require to include it as a dependency and also generate the composer. As you can see from the output, Composer automatically decided which version of the package to use. The vendor directory is where the project dependencies are located. When installing a project that already contains a composer.
If you check the contents of your composer. Composer supports several different constraints and formats for defining the required package version, in order to provide flexibility while also keeping your project stable. In this case, it defines 3. Here are some examples to give you a better understanding of how Composer version constraints work:. For a more in-depth view of Composer version constraints, see the official documentation.For Fortran programming, you can use latest Fortran compilers but compilation of some old packages and softwares may still need g Since, g77 is not easily found in current repositories, you need to install it using source code for Linux.
There may appear some errors during installation due to the incompatiblities of present systems with g In this article, we will install g77 fortran compiler and solve all those issues for Ubuntu Now, you need to extract the content of this file and run install. You need to change the permission of install.
Now, we need to check whether Fortran 77 compiler is installed properly or not. Make a simple Fortran program and save as file named hello. You should see a new file named a. We need to edit the. Please add any one of the above to. While editing.
Installing the GNU C compiler and GNU C++ compiler
Now reload your. Now again try to compile g77 and you will see that the first two errors are removed and only one is left. You can help it, by finding the library yourself:.
It may return various version for library, we can select the latest one. Now we need to check where the ld is expecting the library.
Now, we will make a symbolic link from where the actual file is to one of these locations then ld can find it and error will be removed. Although you are able to run g77 compiler successfully but you may see an error while upgrading your ubuntu.
Although, the above installation of Fortran 77 compiler is shown for Ubuntu Hi, I can't help with your specific issue. But just in case: In the past I'd problems too after upgrading Ubuntu to a newer release. From Since then I prefer to install a new Ubuntu release from scratch, and not to just upgrade an older Ubuntu release.
Best Regards. I actually tried either with the new Ubuntu after formatting the original one, but I still encounter the same problem. I remember that the Ubuntu releases prior to It usually ends up to be the result of some issue in the configure scripts. It's possible that the new versions of autotools or whatever build tools used does not like something in HDF5 configuration scripts. Quote: Eugene Epshteyn Intel wrote:.

If you are sure that you added a repository that contains gfortran Keep in mind that many PPAs don't provide packages for bionic yet. This seems like a Mathworks support question more than an Ubuntu question. No, I am not sure I added the good repositories; the problem is this, I can not find references to these repositories, if they exist.

To install the GNU Java bytecode interpreter, you need the gij package. To have gcj compile to executables, install libgcj6-dev otherwise an error during compilation occurs: libgcj. Use synaptic to install libgcj6-dev. To install the GNU Fortran 95 compiler - gfortranthe package is: gfortran.
Installing the GNU autotools To install autoconf and automakeyou need the autoconf and automake packages. Apt-get will tell you to explicitly choose a version of automake. If, for example, you decide to use automake1. The critical options are -m32 to build bit and -m64 to build bit. These options will be present when you install the compiler of your choice. However, they won't actually work unless you install several additional packages. The first thing you will need is the multilib package for the compiler you are using.
For 4. The multilib packages are compiler runtime packages. Now, you need bit or bit versions of whatever libraries you need to link your application program. Install these on bit systems to support bit builds. Get the License Number and Extract to a path without spaces Ensure that you have obtained the license number for your installation and extracted the downloaded installation archive into a path that does not contain any spaces.
This last statement is utterly important. The installer script that comes with the package has a bug that does not allow you to install the compiler suite if you have any spaces in the installer script path.Not everything old is bad.
This is how it is. Well, while it is true that there are many programming languages today, there are some that have been a little forgotten as Fortran. However, many companies still need development in this language and not only that but there are tools that have evolved in favor of this language. This compiler created by GNU is an open source alternative to other compilers that are not. If we speak mythical programming languages, we will have to talk about Fortran.
It is a language focused on numerical calculation, designed in its beginnings for IBM computers and used in scientific and engineering applications and is the oldest of the high-level languages. Therefore, Fortran was very important in computer science in the last century. You might think that nobody uses it anymore or something does. But the banking sector, in the scientific sector and in other companies that still use this language, pay good amounts of money for experts in the language.
It is because of this that many programmers have turned their eyes to Fortran. It is also known on the Internet as GFortran. It is open source, released under the GPL license. With the aim of creating a modern compiler capable of running on multiple systems and multiple environments.
The latest version available is version 9. It has many improvements in every Fortran version it supports. You can check the improvements here. Fortran is a very old programming language. However, there are sectors where it is very important and that is why there are still tools for the language. If you are a developer, you can get more post about programming.
