Hello.
I have troubles to codesign a binary compiled with gcc-mp-48
Previously I was using XCode's gcc (4.2.1) and everything was ok.
a.cpp:
int main() { return 1; }
Compiled with gcc 4.2.1:
> /usr/bin/gcc a.cpp
> security unlock-keychain ~/my.keychain
password to unlock /Users/me/my.keychain: ********
> codesign -f -s "identity" --keychain ~/my.keychain a.out
> codesign -v -v a.out
a.out: valid on disk
a.out: satisfies its Designated Requirement
(success)
Compiled with gcc 4.8 (macports)
> /opt/local/bin/gcc-mp-4.8 a.cpp
> security unlock-keychain ~/my.keychain
password to unlock /Users/me/my.keychain: ********
> codesign -f -s "identity" --keychain ~/my.keychain a.out
codesign_allocate: object: /Users/me/a.out malformed object (unknown
load command 9)
a.out: object file format invalid or unsuitable
(failure)
I then found out there was a codesign_allocate in macports bin, so I tried:
> export CODESIGN_ALLOCATE=/opt/local/bin/codesign_allocate
> security unlock-keychain ~/my.keychain
password to unlock /Users/me/my.keychain: ********
> codesign -f -s "identity" --keychain ~/my.keychain a.out
a.out: code object is not signed
Uh? When I specify macports codesign_allocate, codesign doesn't even try
to sign, it just verifies the (unavailable) signature of my binary.
However, detached signature works, with or without macports
codesign_allocate:
> codesign -f -s "identity" --keychain ~/my.keychain a.out
--detached a.out.signature
> codesign -v -v a.out --detached a.out.signature
a.out: valid on disk
a.out: satisfies its Designated Requirement
So codesign and codesign_allocate works with gcc48-compiled binaries,
but for some reason fails to understand that it should embed the
signature in the binary.
Anybody have a clue about that? Or maybe a way to embed the signature
after it has been created detached?
Note: My personal Mac/OSX knowledge is basic to medium, and I need to
use only command-line tools to create working, ideally signed, binaries.
The build process is highly automated on several platforms.

NH
