Description Fedora Release Engineering 2021-02-01 16:37:09 UTC 
thermald failed to build from source in Fedora rawhide/f34

https://koji.fedoraproject.org/koji/taskinfo?taskID=60906802


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_34_Mass_Rebuild
Please fix thermald at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
thermald will be orphaned. Before branching of Fedora 35,
thermald will be retired, if it still fails to build.

Comment 4 Benjamin Berg 2021-02-02 14:08:11 UTC 
As I see it, it is choking on a static c string assignment to an std:string. i.e. the code does:

modem_path.assign("/ril_0");

where modem_path is defined as "std::string modem_path;" inside "class cthd_cdev_modem".
Comment 5 Ben Cotton 2021-02-09 15:47:55 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.

Same as in bug 1909564, the warning below (copied from https://kojipkgs.fedoraproject.org//work/tasks/1800/60911800/build.log) is due to upstream GCC bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98465.
