BCC(1) - General Commands Manual


bcc - binary to C/C++ arrays converter


bcc [-0cs] [-I num] [-i num] filename variable


The bcc utility converts the input file into a C or C++ array named variable that can be embedded as-is in the source code. A special - value can be passed as input which will read standard input instead.

The variable can contain any character but only ones that are allowed in the C standard will be kept, other will be replaced with a “_”. Also, the extension (by finding the first .) is removed as well. This can be handy when generating a lots of file based on their names during a build process.

Note: you must still not start a variable name with digits.

The following options are available:


Terminate the generated array with a trailing NUL.


Generates a const array.


Generates a static array.

-I num

Use num count as leading tab indents.

-i num

Use num count as leading space indents.


Create a static, const array from an image.

bcc -sc image.png image > image.h

Create a modifiable array from a text file as a NUL terminated string.

bcc -0 text.txt text > text.h


The bcc tool is inspired by xxd utility but offers more flexibility over the the generated code.
