--- Comment #15 from sujay1844 at protonmail dot com --- I did some digging and found this:- I checked my timeshift snapshot (which I took just after installation). The etc/makepkg.conf is that goes like so:- #-- Compiler and Linker Flags CPPFLAGS="-D_FORTIFY_SOURCE=2" CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fno-plt" CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fno-plt" LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now" #RUSTFLAGS="-C opt-level=2" #-- Make Flags: change this for DistCC/SMP systems #MAKEFLAGS="-j2" #-- Debugging flags DEBUG_CFLAGS="-g -fvar-tracking-assignments" DEBUG_CXXFLAGS="-g -fvar-tracking-assignments" #DEBUG_RUSTFLAGS="-C debuginfo=2" To be sure that this is safe, I installed Manjaro in a virtual machine. (Clearly, the guys at Manjaro know more about security than me) The /etc/makepkg.conf had the same thing as in my timeshift snapshot. So I conclude that removing those unwanted flags are safe. I also checked the ArchWiki article on makepkg and made some tweaks to improve performance and this is my current /etc/makepkg.conf looks like:- #-- Compiler and Linker Flags CPPFLAGS="-D_FORTIFY_SOURCE=2" CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fno-plt" CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fno-plt" LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now" #RUSTFLAGS="-C opt-level=2" #-- Make Flags: change this for DistCC/SMP systems #MAKEFLAGS="-j2" #-- Debugging flags DEBUG_CFLAGS="-g -fvar-tracking-assignments" DEBUG_CXXFLAGS="-g -fvar-tracking-assignments" #DEBUG_RUSTFLAGS="-C debuginfo=2" Thank you for your valuable time!! Please give any suggestions if any. And you can close this bug.
