I posted this question to StackOverflow a little while ago, but just now found this community, and felt like this is at least an equally appropriate site for this question:I've been led to understand that if abrt-ccpp.service is installed on a Linux PC, it supersedes/overwrites (I've read both, not sure which is true) the file /proc/sys/kernel/core_pattern, which otherwise specifies the location and filename pattern of core files.Question:When I execute systemctl, why does abrt-ccpp.service report exited under the SUB column? I don't understand the combination of active and exited: is the service alive/active/running or not?> systemctlUNIT                 LOAD   ACTIVE SUBabrt-ccpp.service    loaded active exited ...Question:Where are core files generated? I wrote this program to generate a SIGSEGV:#include <iostream>int main(int argc, char* argv[], char* envz[]){  int* pInt = NULL;  std::cout << *pInt << std::endl;  return 0;}Compilation and execution as follows:> g++ main.cpp> ./a.outSegmentation fault (core dumped)But I cannot locate where the core file is generated.What I have tried:Looked in the same directory as my main.cpp. Core file is not there.Looked in /var/tmp/abrt/ because of the following comment in /etc/abrt/abrt.conf. Core file is not there....# Specify where you want to store coredumps and all files which are needed for# reporting. (default:/var/tmp/abrt)## Changing dump location could cause problems with SELinux. See man_abrt_selinux(8).##DumpLocation = /var/tmp/abrt...Looked in /var/spool/abrt/ because of a comment at this link. Core file is not there.Edited /etc/abrt/abrt.conf and uncommented and set DumpLocation = ~/foo which is an existing directory. Followed this by restarting abrt-hook-ccpp (sudo service abrt-ccpp restart) and rerunning a.out. Core file was not generated in ~/foo/Verified that ulimit -c reports unlimited.I am out of ideas of what else to try and where else to look.In case helpful, this is the content of my /proc/sys/kernel/core_pattern: > cat /proc/sys/kernel/core_pattern|/usr/libexec/abrt-hook-ccpp %s %c %p %u %g %t eCan someone help explain how the abrt-hook-ccpp service works and where it generates core files? Thank you.
Where is core file with abrt-hook-cpp installed?
linux;core dump;abrt
One possibility is the need to change the line in the config file /etc/abrt/abrt-action-save-package-data.confProcessUnpackaged = noto yes, otherwise abrtd will only capture corefiles from programsinstalled by the package manager (dnf, apt, or whatever). Use abrt-gui or abrt-cli to look for core dumps.
