Need to disable codesign

[Trcx528]

try adding after sys.argv in the if statement.  IE:

Code: [Select]

if sys.argv[i] == "-o":

OK, now that's solved, but I still get this:

  File "/usr/bin/gcc", line 9, in <module>
    if not output:
NameError: name 'output' is not defined

My gcc:
#!/usr/bin/env python

import os, sys
os.system("realgcc " + " ".join(sys.argv[1:]))
for i in range(0,len(sys.argv)-1):
    if sys.argv == "-o":
        output = sys.argv[i+1]
        break
if not output:
    output = "a.out"

os.system("ldid -S %s" % output)

Thanks for the support

Dude, old post. Anyways, you should use something more like this:

Code: [Select]

#!/usr/bin/env python

import sys, os

output = "a.out"

for i in range(1, len(sys.argv)):
    if sys.argv[i] == "-o":
        output = sys.argv[i+1]
        break

if os.system("realgcc " + " ".join(sys.argv[1:]) + " >err.log 2>&1"):
    os.system("ldid -S '%s'" % (output,))

else:
    print("Compile error(s):\n" + open("err.log").read())

Just so you know, this script could be easily improved by using the subprocess module instead of os.system. I just wrote this as a quick example.

Thanks C0deH4cker. Unfortunately, this still does not fix all, as the program is still killed:
./configure: line 4756: 15120 Killed: 9               ./conftest$ac_cv_exeext
configure:4758: $? = 137
configure:4767: error: cannot run C compiled programs.

I think I can read what python is doing, but I don't have the knowledge to (re)write any piece of code in this language.

There have been alternative solutions?

[C0deH4cker]

Did you save this script as /usr/bin/gcc and move gcc to /usr/bin/realgcc? Also, you might want to run CC=/usr/bin/pygcc ./configure, assuming that the script is saved as /usr/bin/pygcc.

[LeoTh3o]

I did save the script as gcc after moving the real gcc aside. I have set chmod +x to the new gcc and still it doesn't seem to work. has anyone this problem? I'm using an iPad2 iOS 5.1.1

Did you sign it with ldid?

[C0deH4cker]

ldid -S /usr/bin/realgcc

[Trcx528]

I manged to get the configure script to run by telling the system that it was cross compiling. 

Code: [Select]

./configure --host=arm-apple-darwin
additionally I added a working bash script to codesign....not sure if it's doing me any good though. 

Code: [Select]


#!/bin/bash

output='a.out'
next=false
for arg in "$@" ; do
        if [ "$next" == "true" ]; then
                output=$arg
                break
        elif [ "$arg" == "-o" ]; then
                next="true"
        fi
done

realgcc $*

if [ -f "$output" ]; then
        ldid -S "$output"
        ldid -s "$output"
        ldid -S "$output"
        ldid -s "$output"
        echo "Signed with ldid"
fi

Redundant much?

[Trcx528]

Haha, I guess that might be a little over kill, but hey it works. 

[C0deH4cker]

Lol

[LeoTh3o]

Finally it worked! Thanks trcx528

[Trcx528]

Hey, no worries.  Glad to help.  The only catch is you might need some additional arguments to configure in order to give it information about the target system (since it thinks it is cross compiling), but generally speaking that shouldn't be too big of a deal.
