Source: swig2.0 Version: 2.0.12-1 Severity: wishlist Tags: patch Hi,
First of all, thanks for taking care of SWIG in Debian! I came across it as part of my work on this year's "Bootstrappable Debian" Google Summer of Code project. The goal of the project is to figure out ways to modify packages, possibly using the new build profiles mechanism, in order to resolve circular build dependencies as described on the http://bootstrap.debian.net/amd64/ pages. SWIG came up because it's present in the "Feedback Arc Set" listed there, and because the version-specific pages linked to from http://bootstrap.debian.net/source/swig2.0.html suggested that it might be advisable to remove the build dependency on default-jdk, since that would solve several dependency loops in one fell swoop. To my great surprise, when I tried building the swig2.0 packages with B-D: default-jdk removed and "with_java" set to something else in the rules file, it turned out that SWIG builds just fine, and that there are absolutely no differences, none at all, in the generated binary packages. As it happens, the SWIG configure script checks for Java, but then nothing ever uses the values, nothing builds anything Java-related, nothing even writes the values to installed files. So what do you think about the attached trivial patch that, perhaps temporarily, drops the Java build dependency and disables the Java checks during the build? Of course, if in the future SWIG decides to actually use Java, we may have to revisit this - but for the present it would help bootstrapping Debian on new architectures by easily removing a build dependency loop without any adverse effects at all. Thanks again for your work on SWIG and Debian in general!

From 94ccf803abb3a299d1ca3181b388e65bd2b12f37 Mon Sep 17 00:00:00 2001 From: Peter Pentchev <[email protected]> Date: Sat, 28 Jun 2014 01:55:34 +0300 Subject: [PATCH] Remove the unused default-jdk build dependency. The SWIG build does not ever use the Java compiler that the configure script checks for. The checks are there, the various Makefile.in files set the variables to the values obtained by the configure script, but nothing ever uses them. This fixes a circular build dependency as noted in the version-specific pages linked to from http://bootstrap.debian.net/source/swig2.0.html --- debian/control | 1 - debian/rules | 2 +- 2 files changed, 1 insertion(+), 2 deletions(-) diff --git a/debian/control b/debian/control index 2e97484..3a96284 100644 --- a/debian/control +++ b/debian/control @@ -10,7 +10,6 @@ Build-Depends: dpkg-dev (>= 1.16.1~), bison, debhelper (>= 7.0), dh-autoreconf, - default-jdk [!hppa !mips !mipsel !alpha !arm !hurd-i386], guile-2.0-dev, libchicken-dev [!m68k !mips !mipsel], libperl-dev, diff --git a/debian/rules b/debian/rules index 02f0d21..5f53c97 100755 --- a/debian/rules +++ b/debian/rules @@ -29,7 +29,7 @@ CONFIGURE_ARGS := \ DEB_TARGET_ARCH := $(shell dpkg-architecture -qDEB_HOST_ARCH) -with_java := yes +with_java := not used during the build at all no_java_archs := hppa hurd-i386 mips mipsel netbsd-i386 ifneq ($(DEB_TARGET_ARCH),i386) ifeq ($(DEB_TARGET_ARCH), $(findstring $(DEB_TARGET_ARCH),$(no_java_archs))) -- 2.0.0
