Package: dpkg-cross Version: 2.5.3 Severity: normal Tags: patch User: [email protected] Usertags: origin-ubuntu ubuntu-patch lucid
dpkg-cross mishandles the dependency_libs lines in many .la files. Attached are two examples. libusb: in: dependency_libs=' -L/usr/arm-linux-gnueabi/lib' out: dependency_libs=' want: dependency_libs='' libanthy: in: dependency_libs=' -lm /usr/lib/libanthydic.la' out: dependency_libs=' -lm /usr/lib/libanthydic.la' want: dependency_libs=' -lm /usr/arm-linux-gnueabi/lib/libanthydic.la' This is no doubt another cause of a number of problems such as http://lists.debian.org/debian-devel/2007/12/msg00416.html. I spent quite a bit of time scratching my head over this before realising that dpkg-cross wasn't behaving as it's clearly intended to behave ... Here's a patch to correct this. === modified file 'dpkg-cross' --- dpkg-cross 2010-01-07 23:47:08 +0000 +++ dpkg-cross 2010-01-14 16:20:48 +0000 @@ -664,10 +664,11 @@ sub sub_build { while (<FROM>) { if (/^libdir=/) { print TO "libdir=\'$crosslib\'\n"; - } elsif (/^dependency_libs=/) { - s/( )?-L\S+//g; - s:\S+/([\w\.\-]+\.la)$:$crosslib/$1:g; - print TO; + } elsif (/^dependency_libs='(.*)'$/ or /^dependency_libs=(.*)/) { + my $deplibs = $1; + $deplibs =~ s/( )?-L\S+//g; + $deplibs =~ s:\S+/([\w\.\-]+\.la)$:$crosslib/$1:g; + print TO "dependency_libs='$deplibs'\n"; } else { print TO; } Thanks, -- Colin Watson [[email protected]]
