Subject: How to Compile Static Executables w/ PIE + SSP + BIND_NOW?
Arch Linux. Example app: mksh.
CC=musl-gcc
CFLAGS+=' -static'
export CC CFLAGS
sh Build.sh -r -c lto
Using typical build flags:
CFLAGS="-march=amdfam15 -O2 -pipe -fstack-protector-all -fPIE"
LDFLAGS="-Wl,-z,now -Wl,-z,relro"
Does produce a static executable but without PIE or SSP. Have tried various options to no avail:
CFLAGS+=' -static -pie'
..with..
CFLAGS="-O2 -fstack-protector-strong"
LDFLAGS="-Wl,-z,now -Wl,-z,relro"
...and...
CFLAGS+=' -shared -pie -static'
..with..
CFLAGS="-O2 -fstack-protector-all"
LDFLAGS="-Wl,-z,now -Wl,-z,relro"
...and many other combos without success. How to create a static exe built against musl with PIE + SSP + BIND_NOW?
