I install OS X Yosemite and now i have a huge problem with gcc 4.9.1 compiler.
I hope some one can help me please.
I try to compile my program and i have the warning message:
gcc: warning: couldn’t understand kern.osversion ‘14.0.0'
I search on google and i find https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61407
I try to apply the patch doing:
sudo patch -p1 < /usr/local/bin/00-darwin-10.10.patch
in gcc folder: /usr/local/bin/gcc
and i received the message:
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff --git a/fixincludes/fixincl.x b/fixincludes/fixincl.x
|index dd45802..0db14d7 100644
|--- a/fixincludes/fixincl.x

Anyone can help me?
I had a similar issue when building things from source, and it was because I forgot to install the updated command line tools after upgrading to Yosemite and xcode 6.1. Try this in your command line:
xcode-select --install
That will download and install the command line tools and may fix your problem.
If you set MACOSX_DEPLOYMENT_TARGET=10.9 in your environment prior to compiling, the shared object linking should work properly.
if you're using Homebrew, simply:
brew upgrade gcc
This was enough for me, and it doesn't require any symlink:
export CC=/Applications/Xcode.app/Contents/Developer/usr/bin/gcc
After that, just run the command as usual.
This solve my problem: I link gcc with /Applications//Xcode.app/Contents/Developer/usr/bin/gcc
cd /usr/local/bin
ln -s /Applications//Xcode.app/Contents/Developer/usr/bin/gcc gcc
The patch you are trying to use is for patching the source code of GCC, and you are trying to use it to patch the compiled binary. That won't work.
In theory the process would be
- Download source tarball of GCC compiler
- apply the patch to it
- compile GCC
- Install the compiled GCC
However, you are unlikely to be able to do this since you cannot run the compiler in order to compile a newer copy of itself. Catch-22!
Searching google for 'gcc yosemite' I found a number of references to possible solutions, eg. enter link description here. I'm afraid I am no mac expert so I cannot judge the quality of these solutions.
I am also getting the warning "couldn't understand kern.osversion `14.0.0'" on GFORTRAN compilations while running Yosemite (10.10.1) with Xcode 6.1 and GCC 5.0. The compiler, however, generates functioning executable code and it seems to run correctly. Maybe you can just ignore the warning?
I solved an issue by linking
export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
It seems to want a current version of XCode command line tools. When I first typed "make" after installing Yosemite I got a warning and a dialog box saying that I did not have XCode command line tools and asked if I wanted to install them. I did so, and everything worked.
However one user did not get this dialog and instead got the error message as shown. The "xcode-select --install" did not work, so it seems like it may have kept the outdated command line tools and header files.
The MACOSX_DEPLOYMENT_TARGET=10.9 solution did work for him. However the compiles seemed to be a lot slower.
I had this issue, installed Xcode cli tools (xcode-select --install), and still had issues. I'd upgraded from Yosemite to Mojave, and uninstalling an older version of the compiler worked for me:
brew uninstall apple-gcc42
Hope this helps someone!
