[Bug 1489379] Re: LTE: ISST:leeklp4 no mpath choices for install ubuntu 15.10
This bug was fixed in the package multipath-tools - 0.5.0-7ubuntu4 --- multipath-tools (0.5.0-7ubuntu4) wily; urgency=medium * Disable -fexceptions on multipath-udeb (LP: #1489379): the flag causes libchecktur.so to link with libgcc_s.so.1 (even with -static-libgcc), which is not available in the installer environment. - debian/patches/disable-fexceptions-udeb.patch: conditionally disable -fexceptions with CFLAGS_DISABLE_FEXCEPTIONS. - debian/rules: set CFLAGS_DISABLE_FEXCEPTIONS to build multipath-udeb. -- Mauricio Faria de Oliveira Thu, 03 Sep 2015 07:29:59 -0400 ** Changed in: multipath-tools (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1489379 Title: LTE: ISST:leeklp4 no mpath choices for install ubuntu 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1489379/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The attachment "Disable -fexceptions when building multipath-udeb" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.

[Bug 1489379] Re: LTE: ISST:leeklp4 no mpath choices for install ubuntu 15.10
I'm attaching a patch that solves the issue; verification steps below. It disables -fexceptions when building multipath-udeb. (I had in mind something more elegant, like only adding -fno-exceptions from debian/rules into DEB_CFLAGS_MAINT_APPEND as done w/ -static- libgcc, but that way it doesn't override the post-added -fexceptions in Makefile.inc).. and found no other variable that would override it w/ less changes. So it's adding a patch to Makefile.inc and it does the job.) Some comments with more details/explanation of the issue were not mirrored yet; should be on their way. Build verification: -- Checking the build log, the 2 tur.o objects are built correctly: 1) multipath-udeb: with -static-libgcc and without -fexceptions 2) multipath deb: without -static-libgcc and with -fexceptions (default) $ dpkg-buildpackage 2>&1 | tee ../dpkg-buildpackage.log $ grep -- '-o tur.o' ../dpkg-buildpackage.log cc -g -O3 -fPIE -fstack-protector-strong -Wformat -Werror=format-security -static-libgcc -D_FORTIFY_SOURCE=2 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 -Wunused -Wstrict-prototypes -fPIC -DLIB_STRING=\"lib\" -I.. -c -o tur.o tur.c cc -g -O3 -fPIE -fstack-protector-strong -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -Wunused -Wstrict-prototypes -fPIC -DLIB_STRING=\"lib\" -I.. -c -o tur.o tur.c Checking the build output, the ELF objects (don't) dyn-link to libgcc_s as appropriate: 1) multipath-udeb: ELF objects don't dyn-link with libgcc_s 2) multipath deb: ELF objects dyn-link with libgcc_s $ find debian/tmp-multipath-udeb/ | while read file; do file $file | grep -q ELF && objdump -x $file | grep -q 'NEEDED.*libgcc_s' && echo $file needs libgcc_s; done $ $ find debian/tmp/ | while read file; do file $file | grep -q ELF && objdump -x $file | grep -q 'NEEDED.*libgcc_s' && echo $file needs libgcc_s; done debian/tmp/lib/libmultipath.so.0 needs libgcc_s debian/tmp/lib/multipath/libchecktur.so needs libgcc_s debian/tmp/sbin/multipathd needs libgcc_s $ Installer verification: --- Configure multipath.conf for using tur with QEMU/KVM SCSI disks: ~ # cat | A dynamic linking error occurred: (libgcc_s.so.1: cannot open shared object file: No such file or directory) uuid hcildev dev_t pri dm_st chk_st vend/prod/rev dev_st 0:0:1:0 sda 8:0 -1 undef faulty QEMU,QEMU HARDDISK running 0:0:2:0 sdb 8:16 -1 undef faulty QEMU,QEMU HARDDISK running ...

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode. To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1489379/+editstatus and add the package name in the text box next to the word Package.
