GCC cross compiler (see the next section)
GCC cross compiler
Method 1 - Compile from GCC source.
Follow the instructions from wiki.osdev.org/GCC_Cross-Compiler
Set the "TARGET" to "x86_64-elf" instead of "i686-elf" and build libgcc without redzone wiki.osdev.org/Libgcc_without_red_zone.
Method 2 - Precompiled binaries
VERSION: GCC 7.3 + Binutils 2.30
HOST: x86_64-pc-linux-gnu
CONFIGURED WITH: --target=x86_64-elf --disable-nls --enable-languages=c,c++ --without-headers
-
Download "cross.tar.gz" from the Github release page.
-
Run "tar -xvf cross.tar.gz -C $HOME/opt/cross"
Compiling
Run "make" in the root directory.
This will generate secxkrnl.elf (kernel executable) and secxkrnl.dmp (kernel dump).
Run "make clean" to clean a build.
Running
secX requires bootloader secboot (github.com/secXsQuared/secboot).
See secboot repository for more information.
