compiler complains about messed up CFLAGS in build log: <command-line>: warning: "_FORTIFY_SOURCE" redefined <command-line>: note: this is the location of the previous definition and then linker fails: mips-openwrt-linux-musl-gcc [...] -o dropbearmulti [...] collect2: fatal error: ld terminated with signal 11 [Segmentation fault] compilation terminated. /staging_dir/toolchain-mips_24kc_gcc-8.2.0_musl/mips-openwrt-linux-musl/bin/ld: /tmp/cc27zORz.ltrans0.ltrans.o: relocation R_MIPS_HI16 against `cipher_descriptor' can not be used when making a shared object; recompile with -fPIC /staging_dir/toolchain-mips_24kc_gcc-8.2.0_musl/mips-openwrt-linux-musl/bin/ld: /tmp/cc27zORz.ltrans1.ltrans.o: relocation R_MIPS_HI16 against `ses' can not be used when making a shared object; recompile with -fPIC /staging_dir/toolchain-mips_24kc_gcc-8.2.0_musl/mips-openwrt-linux-musl/bin/ld: /tmp/cc27zORz.ltrans2.ltrans.o: relocation R_MIPS_HI16 against `cipher_descriptor' can not be used when making a shared object; recompile with -fPIC /staging_dir/toolchain-mips_24kc_gcc-8.2.0_musl/mips-openwrt-linux-musl/bin/ld: BFD (GNU Binutils) 2.31.1 assertion fail elfxx-mips.c:6550 [...] /staging_dir/toolchain-mips_24kc_gcc-8.2.0_musl/mips-openwrt-linux-musl/bin/ld: BFD (GNU Binutils) 2.31.1 assertion fail elfxx-mips.c:6550 make[3]: *** [Makefile:198: dropbearmulti] Error 1 make[3]: *** Deleting file 'dropbearmulti' make[3]: Leaving directory '/build_dir/target-mips_24kc_musl/dropbear-2018.76' make[2]: *** [Makefile:158: /build_dir/target-mips_24kc_musl/dropbear-2018.76/.built] Error 2 make[2]: Leaving directory '/package/network/services/dropbear' This FTBFS issue was caused by hardening flags set up by dropbear's configure script. By default, Dropbear offers hardening via CFLAGS and LDFLAGS, but this may break or confuse OpenWrt settings. Remove most Dropbear's hardening settings in favour of precise build, but preserve Spectre v2 mitigations: * -mfunction-return=thunk * -mindirect-branch=thunk Signed-off-by: Konstantin Demin <rockdrilla@gmail.com>

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
