celforyon/compiler-explorer repository overview

⁠Compiler Explorer

Self-hosted version of https://godbolt.org/⁠

⁠Usage

⁠Relevant directories

• /opt: typically add compilers here
• /usr/local/bin: (in the user PATH)
• /ce/config: configuration files for Compiler Explorer compilers
• /ce/examples: default and examples files for languages
• /ce/docs: documentations from Compiler Explorer git repository
• /compiler-explorer/lib: languages.js contain the list of supported languages

⁠ENV

• PUID: user UID (1000)
• PGID: user GID (1000)
• GCC_MIRROR: URL for GCC releases mirror ("ftp://ftp.uvsq.fr/pub/gcc/")

⁠/ce/compiler-adapter

Compiler Explorer use a default commandline looking like:

-g -o <output> -S <additional flags added by user> <input>

which could be impractical for interpreter-like compilers. This binary currently does this:

• isolates <src>
• isolates <out>
• removes extra flags -g, -o and -S
• writes a file (<input>) containing all data after --- if encountered in commandline
• detect if required output must be executable (<exe>)

You can use it by creating a symbolic link named compiler.name, where name is an executable in the PATH.

It then calls ./name if file exists and is executable, else name with these arguments:

• <exe> (boolean, 1 if <out> must be executable)
• <out>
• <src>
• <input> (file containing data after ---)
• <args> (user arguments before ---)

It will also call this with the only argument:

• --version

to give Compiler Explorer information about it. If this call fails, it will answer Compiler Explorer with name.

⁠/ce/install_gcc

Arguments:

• version (complete, e.g. 8.1.0)
• extension (optional, default: tar.xz)

Will install GCC in /opt/gcc-${gcc_version}.
