CPROC(1)

NAME
cproc - C11 compiler

SYNOPSIS
cproc [options] sources...

DESCRIPTION
cproc is a C11 compiler using QBE as backend. It supports ISO C11, some features from the upcoming C23, and some GNU C extensions.

When invoked without any options, cproc will preprocess, compile, and link sources... and generate an executable a.out file.

The following options are available:

-c  Compile sources to object files rather than linking them.

-D macro[=value]
    Define macro to value as if by a preprocessor #define. If value is not given, macro is defined to 1.

-E  Preprocess the input files and print the output rather than compiling.

-I path
    Append path to the list of directories to be searched for headers.

-L path
    Append path to the list of directories to be searched for libraries.

-l library
    Link library to the executable. If library is a relative path, it will be searched through the compiler search paths.

-o output
    Write the output to output. By default, output is written to a.out. Or, if -c is used, the output file is determined by replacing the source file extension with .o. Or, if -E or -emit-qbe is used, the output is written to standard output.

-s  Strip the symbol table from the generated executable.

-U macro
    Undefine a pre-defined macro.

-v  Print the commands run as part of the compile pipeline.

-x format
    Force cproc to interpret subsequent source files as format. By default, cproc will determine source code language from the known file extensions. This option forces a different format which can be one of “none”, “c”, “c-header”, “cpp-output”, “qbe”, “assembler”, “assembler-with-cpp”.

-Wa,args..., -Wl,args..., -Wp,args...
    For each of these options, pass additional args... to the assembler, linker, or preprocessor respectively. The list of arguments is delimited by commas.

    For example, -Wl,--gc-sections will forward the option --gc-sections to the linker.

-static
    Link the executable statically.

-nostdlib
    Do not use standard library and startup files when linking.

-nostdinc
    Do not search default compiler include paths when compiling.

-pthread
    This is a short hand of -lpthread.

-g, -O, -pipe, -pedantic, -pedantic-errors
    These options are available for compatibility with most common compilers but are currently ineffective.
