A quick C program for embedding binary files into array in .c file.
This repo also has additional cmake function script for automatically embedding files
gcc -o Embed2C embed.c (Add .exe on Windows)
or
mkdir Build && cd Build && cmake .. && cmake --build . (Might need to add generator arguments on Windows)
Embed2C "<path/to/file/to/embed>" "EmbeddedFile" "<path/to/file2/to/embed>" "EmbeddedFile2" ...
which will output to console:
#include <stdint.h>
#include <stddef.h>
const uint8_t EmbeddedFile[] = {
//Contents...
};
const size_t EmbeddedFile_size;
const uint8_t EmbeddedFile2[] = {
//Contents...
};
const size_t EmbeddedFile2_size;You can save the output from console to a file with Embed2C ... > EmbeddedFiles.c
To use the variable in other files, just forward declarate like this
extern const uint8_t EmbeddedFile[];
extern const size_t EmbeddedFile_size;
extern const uint8_t EmbeddedFile2[];
extern const size_t EmbeddedFile2_size;or put them in a header file
# ...
add_subdirectory("${CMAKE_CURRENT_LIST_DIR}/Path/To/Embed2C" EXCLUDE_FROM_ALL)
include("${CMAKE_CURRENT_LIST_DIR}/Path/To/Embed2C/embedFile.cmake")
# First Get the embed executable path
set(EMBED_EXEC_PATH "")
GET_EXEC_PATH(EMBED_EXEC_PATH)
set(FILES_TO_EMBED "${CMAKE_CURRENT_LIST_DIR}/Path/To/File/To/Embed"
"EmbedVariableName"
"${CMAKE_CURRENT_LIST_DIR}/Path/To/File2/To/Embed"
"Embed2VariableName"
# etc...
)
EMBED_FILES("${EMBED_EXEC_PATH}"
"${CMAKE_CURRENT_LIST_DIR}/Path/To/Output/File.c"
"${FILES_TO_EMBED}")
#...You can check if the embedded C file is populated or not with
file(SIZE "${CMAKE_CURRENT_LIST_DIR}/Path/To/Output/File.c" EMBEDDED_FILE_SIZE)
if(EMBEDDED_FILE_SIZE LESS 1024)
# Pupulate it with EMBED_FILES function
