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?
- You can compile with ifort? Because as I see here you shouldn't be able to compile with ifort neither, but at least with it you have an answer.Alfonso Santiago– Alfonso Santiago2013-10-09 00:42:55 +00:00Commented Oct 9, 2013 at 0:42

- ifort is free for non-commerical & non-academic use.Kyle Kanos– Kyle Kanos2013-10-09 01:12:58 +00:00Commented Oct 9, 2013 at 1:12
- Did you update from 10.5 to 10.9?Kyle Kanos– Kyle Kanos2013-10-09 01:13:27 +00:00Commented Oct 9, 2013 at 1:13
- no, from 10.8.5. Ifort for linux is free, but there's no free version for mac.sigmali– sigmali2013-10-09 01:18:49 +00:00Commented Oct 9, 2013 at 1:18

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/SDKs/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/SDKs/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.

I don't see where in the original question he stated he is using the -static flag?
