Robert Griesemer, Rob Pike and Ken Thompson started sketching the goals for a new language on the white board on September 21, 2007. Within a few days the goals had settled into a plan to do something and a fair idea of what it would be. Design continued part-time in parallel with un...
87 88 When the cgo directives are parsed, any occurrence of the string ${SRCDIR} 89 will be replaced by the absolute path to the directory containing the source 90 file. This allows pre-compiled static libraries to be included in the package 91 directory and linked properly. 92 For examp...
