javascript - "FF FF" is getting dumped as "FD" on some of the computers with Java Scripting API -


i facing issues java scripting api javascript on of pcs. after analyzing dumped file, noticed "ff ff" geeting printed "fd" on of pcs. below code snippet:

var outputfile = new randomaccessfile(f, "rw"); var byte_data_array = getmybytearraydata(somebytearray);  var data_string = new java.lang.string(byte_data_array); outputfile.writebytes(data_string);

you're converting data bytes string without specifying encoding (which uses local-dependant platform default encoding), write file using writebytes() method documented in api doc discarding higher-order byte of each character.

what did expect? i'm surprised result has resemblance @ original data.

what should replace last 2 lines this:

outputfile.write(byte_data_array);

and remember: bytes data, strings text, , if convert between them, need pay attention encoding used.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
