From 939beb11a5ccf58d7fe79a809a1b592c5c9143c0 Mon Sep 17 00:00:00 2001 From: Boris Kolpackov Date: Thu, 11 Nov 2021 13:20:30 +0200 Subject: Add support for dynamic dependencies in ad hoc Buildscript recipes Specifically, add the new `depdb dyndep` builtin that can be used to extract dynamic dependencies from a program run or a file. For example: obje{hello.o}: cxx{hello} {{ s = $path($<[0]) depdb dyndep $cxx.poptions $cc.poptions --what=header --default-prereq-type=h -- $cxx.path $cxx.poptions $cc.poptions $cxx.mode -M -MG $s diag c++ ($<[0]) o = $path($>) $cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -c $s }} Currently only the `make` dependency format is supported. --- libbuild2/build/script/builtin.cli | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 libbuild2/build/script/builtin.cli (limited to 'libbuild2/build/script/builtin.cli') diff --git a/libbuild2/build/script/builtin.cli b/libbuild2/build/script/builtin.cli new file mode 100644 index 0000000..3ed3659 --- /dev/null +++ b/libbuild2/build/script/builtin.cli @@ -0,0 +1,32 @@ +// file : libbuild2/build/script/builtin.cli +// license : MIT; see accompanying LICENSE file + +include ; + +// Note that options in this file are undocumented because we generate neither +// the usage printing code nor man pages.
