If you want to compile with -fsanitize=address, you have to install gcc-toolset-9-libasan-devel first. Does installing that package fix the problem? That would make sense, however it's not available: $ yum install gcc-toolset-9-libasan-devel Updating Subscription Management repositories.

Hmm, that's strange, that package is shipped and available in AppStream. Can you make sure you are using a newer compose than the current one? I agree it's strange, in fact, it don't make sense at all. I don't know what a compose is this context, can you explain? BTW: exactly the same problem in CentOS 8: http://www.mirrorservice.org/sites/mirror.centos.org/8.1.1911/AppStream/x86_64/os/Packages/ There lots of gcc-toolset-9 packages, however no gcc-toolset-9*asan* packages. I am a bit confused by this. (In reply to Terje Røsten from comment #4) > I agree it's strange, in fact, it don't make sense at all. > > I don't know what a compose is this context, can you explain? I mean the "version" of the AppStream repo. Newer (RHEL 8.2) have gcc-toolset-9-libasan-devel. So if you can subscribe to a newer repo, you'll problem will be fixed. I think this is usually done using the subscription manager. > BTW: exactly the same problem in CentOS 8: > > http://www.mirrorservice.org/sites/mirror.centos.org/8.1.1911/AppStream/ > x86_64/os/Packages/ > > There lots of gcc-toolset-9 packages, however no gcc-toolset-9*asan* > packages. > > I am a bit confused by this. Ah, not sure about that. I think it just needs time to be updated. Hmm, looking at the CentOS build I see that gcc-toolset-lib*san* packages are built: https://koji.mbox.centos.org/koji/buildinfo?buildID=6289 however, they are not in repos. http://www.mirrorservice.org/sites/mirror.centos.org/8.1.1911/AppStream/x86_64/os/Packages/ This might be due to: https://bugzilla.redhat.com/show_bug.cgi?id=1722892 libasan5/libubsan1 clash with system libasan/libubsan https://bugzilla.redhat.com/show_bug.cgi?id=1729402 libTsan coming from gcc-toolset-9 leaked through the compose process to RHEL-8.1 BaseOS compose To me is seems like gcc-toolset-*san packages have been filtered from repos due to the two bugs reports above, however that seems like a mistake to me. The value of gcc-toolset-98 is very limited if the toolset is not complete, ASAN is a required tool these days.

Sorry. I deal with developing & building the actual bits, but my insight into how the bits are shipped on CentOS is very limited. > http://www.mirrorservice.org/sites/mirror.centos.org/8.1.1911/AppStream/ > x86_64/os/Packages/ > > This might be due to: > > https://bugzilla.redhat.com/show_bug.cgi?id=1722892 > libasan5/libubsan1 clash with system libasan/libubsan > > https://bugzilla.redhat.com/show_bug.cgi?id=1729402 > libTsan coming from gcc-toolset-9 leaked through the compose process to > RHEL-8.1 BaseOS compose > > > To me is seems like gcc-toolset-*san packages have been filtered from repos > due to the two > bugs reports above, however that seems like a mistake to me. > > The value of gcc-toolset-98 is very limited if the toolset is not complete, > ASAN is > a required tool these days. This was just about the shared *san libraries though, they don't have to be shipped in GTS because the system versions are sufficient. Inviting Jim to comment on the CentOS compose update aspect (see Comment 6). Closing the BZ as it's not a RHEL/DTS problem. The needinfo request[s] on this closed bug have been removed as they have been unresolved for 120 days |
