....so: cannot restore segment prot after reloc: Permission
Posted: Mon Jun 23, 2008 8:11 am
Hi!
The following error was just reported to me while attempting to run a TQ-coupled MICRESS binary under Linux:
'MICRESS_TQ: error while loading shared libraries: [LIBTQ_PATH]/libtq.so: cannot restore segment prot after reloc: Permission denied'
This is not directly related to MICRESS or even TQ, but rather an issue with SE-Linux (see the links mentioned at the end), and the file security layer called 'context' which it introduced: the solution is to reset this so-called context with the following command:
'chcon --verbose --type texrel_shlib_t [LIBTQ_PATH]/libtq.so'
(please note that you might need special priviledges for this command to succeed).
