Hello rojer, or anyone else affected, Accepted golang-1.13 into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/golang-1.13/1.13.8-1ubuntu1~16.04.3 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-xenial. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: golang-1.13 (Ubuntu Xenial) Status: New => Fix Committed ** Tags added: verification-needed verification-needed-xenial ** Changed in: golang-1.13 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913852 Title: zLib link failures on Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/golang-1.13/+bug/1913852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1913852] Re: zLib link failures on Xenial
** Also affects: golang-1.13 (Ubuntu Xenial)
Importance: Undecided
Status: New
** Description changed:
+ [impact]
+ Applications that use the "compress/zlib" package fail to build.
+
+ [test case]
+ $ cat > go.mod
+ module github.com/foo/baz
+
+ go 1.13
+ $ cat > main.go
+ package main
+
+ import (
+ "bytes"
+ "compress/zlib"
+ )
+
+ func main() {
+ var b bytes.Buffer
+ w := zlib.NewWriter()
+ w.Write([]byte("hello, world\n"))
+ w.Close()
+ }
+ $ go build -v
+
+ The final command will fail before this is fixed and pass after.
+
+ [regression potential]
+ The fix is just preventing debhelper from stripping the zlib.a file in
golang-1.13-go. Rebuilding the go toolchain one more time should not introduce
any changes (the go project is pretty good about bootstrap hygiene).
+
+ [original description]
Backported go-1.13 came with issues with zlib.
In some projects i see link errors:

[Bug 1913852] Re: zLib link failures on Xenial
Oh I have dealt with this before: the problem is that debhelper (in xenial) thinks that "zlib.a" is a static library (it's trying to find files with names of the form "libXXX.a" but uses a bad regex) and feeds it to strip as part of the package build, which mangles the file. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913852 Title: zLib link failures on Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/golang-1.13/+bug/1913852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
