Various binaries (/usr/bin/genwqe_cksum, /usr/bin/genwqe_csv2vpd etc.) were not linked with the Fedora linker flags (LDFLAGS) from redhat-rpm-config. I tried to fix this in genwqe-tools-4.0.20, but the LDFLAGS value is not passed down to the actual linker invocation, hence this bug report. Example linker invocation with missing Fedora build flags (-Wl,-z,relro -Wl,-z,now etc): gcc -m64 genwqe_gunzip.o ../lib/libzADC.a -ldl ../lib/libDDCB.a ../lib/libzHW.a ../lib/libcard.a -lpthread -lrt -o genwqe_gunzip
it's fixed in genwqe-tools-4.0.20-3.fc28
