We should document this, if we don't already. And even better would > be if the build failed with a clear error mentioning the need for POSIX sed > (or whichever command it was). I'm happy to fix the POSIX sed requirement if we can find out where it comes in. I can't seem to access any Solaris systems at the moment so I can't recreate it myself. It's true that the Go build requires objcopy. It's interesting that the error message refers to context.o. At that point in the build there should be context.gox in the libgo build directory, and the compiler should find that one first. And even if content.gox doesn't exist for some reason, the context.o file should contain export data in the ".go_export" section. So I'm puzzled. Ian
