Code signing error in macOS Sierra

[eugenesvk]

In macOS Sierra 10.12 Beta (16A312a) when I encounter an error in a console which used to be just colored wonderfully in red by your library, I instead get the following error:

dyld: warning: could not load inserted library '/usr/local/lib/stderred/libstderred.dylib' into library validated process because no suitable image found.  Did find:
        /usr/local/lib/stderred/libstderred.dylib: code signing blocked mmap() of '/usr/local/lib/stderred/libstderred.dylib'

Any idea how to fix this and make the library work again? Thank you

I'm currently running on Sierra and have not changed my install using DYLD_INSERT_LIBRARIES. You can check the way I set it up in my shell configuration files

I've tried this again hoping for a magical auto-fix :), but the issue is still there. After some googling I've downloaded that 9G abomination that is XCode to create a developer code signing certificate to sign the three created libraries (libpolyfill.dylib, libstderred.dylib, and libtest_stderred.dylib) with sudo codesign --force --deep --sign "Mac Developer" -o library /path/to/dylib (I've tried different options, with/without --force, with/without -o or --deep etc), but all I'm just getting is a slightly modified error
(by the way, the library IS working for regular output, but for some commands like git status it gives out these errors, so it's really unusable)

dyld: warning: could not load inserted library '/usr/local/lib/stderred/libstderred.dylib' into library validated process because no suitable image found. Did find:
/usr/local/lib/stderred/libstderred.dylib: code signature in >
(/usr/local/lib/stderred/libstderred.dylib) not valid for use in process using Library Validation: mapping process is a platform binary, but mapped file is not

Any idea on how to fix this code signing issue?

Hi @eugenesvk , i'm currently running in the same kind of trouble. Did you finally find a solution ?

@jmcollin78 no :(
