geraup

Unix-like

To install Gera on a UNIX-like system, the following is required:

• curl is present.
• The JVM (version 17+) is present (java or the GERA_JAVA variable).
• A C compiler is present (clang, gcc, cc or the GERA_CC variable).
• Git is present (git or the GERA_GIT variable).
• ~/.gera does not exist (this is where it will be installed to).

To then install Gera, simply run the following command:

curl https://raw.githubusercontent.com/geralang/geraup/main/install.sh | sh

Windows

Installation

To install Gera on Windows, the following is required:

• curl is present.
• C:\Program Files\Gera does not exist (this is where it will be installed to).

To then install Gera, do the following:

1. Download geraup-win.exe from the latest release.
2. Run the downloaded executable as an administrator.

Further setup

To be able to build / run any Gera code, the following is also required:

• The JVM (version 17+) is present.
• A C compiler is present (if you want to build Gera code with the C target).
• Git is present.

By default, gerap will assume that the JVM is available as java, the C compiler is available as cc and Git is available as git. All of these assumptions can be overwritten:

• Specify the path to the JVM using the GERAP_JAVA_PATH environment variable
• Specify the path to the C compiler using the GERAP_CC_PATH environment variable
• Specify the path to Git using the GERAP_GIT_PATH environment variable.
