Unable to compile Go language on Mac OS X 10.6.7

When following the instructions Getting started - Go programming language , I get the code and try to run the all.bash script.

But I get this error after many other successful results:

Has anyone else seen this and recorded it?

I am running Snow Leopard (10.6.7) build 10J869 .

This is an open-ended question regarding the new version of Xcode for OS X 10.7 and 10.6.7.

Issue 1881 : Constant Error OCP on OS X 10.7

Note: The 142f0bc0d6e7 revision was made to close the 1881 release . To upgrade Go for all changes up to this version, enable this version:

 $ cd $GOROOT/src $ hg pull $ hg update 142f0bc0d6e7 $ ./all.bash

You do not indicate which version of Go you are building. Please note that this is a dynamic project in which versions change frequently.

I just ran hg pull and hg update in the directory where I previously compiled Go successfully (on MacOS X 10.6.7). Then I ran sh all.bash , and I did not see any problems at the build or test stages (although it takes longer to build now than with the first Go declaration).

FWIW, hg tags gives me:

And the end of the build cycle gives:

 --- cd ../test 0 known bugs; 0 unexpected bugs ALL TESTS PASSED --- Installed Go for darwin/amd64 in /Users/jleffler/go. Installed commands in /Users/jleffler/bin. The compiler is 6g.

Therefore...

It is likely that if you change the version of Go (possibly a newer one), then it will work for you too.

And, another FWIW or FYI, I redid the assembly on another machine that also uses MacOS X 10.6.7 this afternoon, and the version of the tooltip is slightly different, and there are apparently 2 known errors.
