Input: filename.bin

Output:

char file_filename_data[] = {
0x47, 0x45, 0x54, 0x20, 0x2f, 0x63, 0x61, 0x6d, 
0x2e, 0x68, 0x74, 0x6d, 0x6c, 0x20, 0x48, 0x54, 
0x54, 0x50, 0x2f, 0x31, 0x2e, 0x31, 0x0d, 0x0a, 
0x48, 0x6f, 0x73, 0x74, 0x3a, 0x20, 0x79, 0x6d, 
0x61, 0x70, 0x2e, 0x64, 0x79, 0x6e, 0x64, 0x6e, 
0x73, 0x2e, 0x6f, 0x72, 0x67, 0x0d, 0x0a, 0x55, 
0x73, 0x65, 0x72, 0x2d, 0x41, 0x67, 0x65, 0x6e, 
0x74, 0x3a, 0x20, 0x4d, 0x6f, 0x7a, 0x69, 0x6c, 
...
}; // This is the data from the file "filename.bin"

size_t file_filename_size = 1234;

I want to store some text files inside an executable file. I am using CMake and building C++ project both in linu开发者_如何学JAVAx and in windows.

Thank you!

xxd is what you're looking for. Example call could be:

xxd -i filename.bin data_output.h

data_output.h would have the contents of:

unsigned char in_file[] = {
  0x68, 0x65, 0x6c, 0x6c, 0x6f
};
unsigned int in_file_len = 5;

Most of the time you can append the information at the end of the file. It's a hack, but it's used by many apps - installers, python freeze (I think), lots of demo coders used it in the past.

Basically just do (CMD.EXE)

echo "Blah" >> myexefile.exe

How would you find this info? Well be inventive - maybe store a unique magic cookie, or just always put the last 4 or 8 bytes to tell you the size of the file, so you can find where it begins.
