#10172: Cross-platform sed -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Build | Version: 7.11 System | Operating System: Solaris Keywords: | Type of failure: None/Unknown Architecture: | Blocked By: Unknown/Multiple | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- It's quite easy to accidentally use GNU extensions in sed expressions, which means Solaris builds start failing. See https://phabricator.haskell.org/D740 for an example. What should we do? Here are a few possibilities: * Force use of POSIX sed with `--posix` flag. I haven't tested, but maybe this won't work if Solaris sed chokes on the `--posix`. Alternately, use `$(SED)` and add `--posix` only if it's supported * Detect GNU sed in autoconfigure and use `$(SED)` in all Makefile scripts * Stop using sed in the scripts for something else I don't know if this admonition applies to other random POSIX tools we use. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10172 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
