2018-02-17 04:44:48 +00:00
|
|
|
##### Method 1 - Compile yourself.
|
2018-02-13 18:29:45 +00:00
|
|
|
Just follow the instructions here: https://wiki.osdev.org/GCC_Cross-Compiler

|
|
|

|
|
|
Remember to set the "TARGET" to x86_64-elf instead of i686-elf and build libgcc without redzone https://wiki.osdev.org/Libgcc_without_red_zone.

### Compiling
|
2018-02-13 18:29:45 +00:00
|
|
|
Run "make all" in the root directory
|
2018-02-13 18:33:24 +00:00
|
|
|
|
2018-02-13 18:29:45 +00:00
|
|
|
The makefile generates secxkrnl.iso (kernel image), secxkrnl.elf(kernel executable), secxkrnl.dmp(kernel disassembly) at the end.
|
|
|
|
|
|
|
|
|
|
To clean all generated files, run "make clean"
|
