gcc - iPhone -mthumb-interlinking -

-

os figured out how use -mthumb , -mno-thumb compiler flag , more or less understand it's doing.

but -mthumb-interlinking flag doing? when needed, , set whole project if set 'compile thumb' in project settings?

thanks info!

open terminal , type man gcc

do mean -mthumb-interwork ?

   -mthumb-interwork        generate code supports calling between arm , thumb        instruction sets.  without option 2 instruction sets        cannot reliably used inside 1 program.  default        -mno-thumb-interwork, since larger code generated when        -mthumb-interwork specified.

if related build configuration, should able set separately each configuration "such release or debug".

why want change these settings? know using thumb instructions save memory save enough matter in case?

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
