From 11dee1bb8fbe6efd85280ca58f3bd2f90baef31a Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Mon, 6 Apr 2020 11:06:53 +0200 Subject: build-self: Avoid call to 'show-what-to-build*' on modern Guix. This avoids repeated "will be downloaded" messages for 'compute-guix-derivation' and its dependencies. * build-aux/build-self.scm (build): Don't call 'show-what-to-build*' when 'with-build-handler' is defined. --- build-aux/build-self.scm | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'build-aux') diff --git a/build-aux/build-self.scm b/build-aux/build-self.scm index 2782a4da72..f86c79f0d0 100644 --- a/build-aux/build-self.scm +++ b/build-aux/build-self.scm @@ -408,7 +408,11 @@ files."
