gfortran doesn't work on Mac OS X 10.9

问题

I updated my Mac to OS X 10.9 GM, then I found that gfortran does not work. When building any program, it shows:

ld: library not found for -lcrt1.10.5.o
collect2: ld return 1

Does anyone know how I might solve this?

回答1:

This problem is because OS X 10.9 has removed the /Developer directory completely where the library crt1.10.5.o used to locate. The libraries have been moved to the new Xcode directory (make sure that Xcode is also updated to the latest version 5.0.1+). I found that crt1.10.5.o is actually hidden deep in here /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/S‌​DKs/MacOSX10.9.sdk/usr/lib. I believe there should be a way to redirect ld automatically, but I do not know how. So for now I am using the -L flag to compile.

gfortran ... -L /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/S‌​DKs/MacOSX10.9.sdk/usr/lib/

This works for me as a temperary solution. I am also waiting for better solutions to come up.

Gfortran has already been compiled for Mac OS X Mavericks 10.9 by http://hpc.sourceforge.net/

First, cd to the root of your Mavericks installation so the files extract recursively into the proper folders

cd /
sudo wget http://prdownloads.sourceforge.net/hpc/gcc-4.9-bin.tar.gz
tar -xvf gcc-4.9-bin.tar.gz

gfortran --help

I had similar problems (ld: library not found for -lcrt0.o) but I discovered that they went away when I stopped using the -static flag with the gfortran command. The -static-libgcc flag seems to be OK.
