it seems to be %__global_cflags -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 - fexceptions -fstack-protector --param=ssp-buffer-size=4 > In any case, Bacula should be compiled using the compiler flags that > are set when Bacula is built from source, rather than from rpmbuild. > Either build from the source tarball or else set the proper CFLAGS > in the global cflags used by rpmbuild, which is set by the > %__global_cflags macro in /usr/lib/rpm/redhat/macros, if you want/ > need an RPM.
