How to compile on Linux ARM64?

[hippie68]

The program won't compile nor link on Linux ARM64.

Here's what I did:

cd src
cmake ../
make

But then an error shows up:

cc: error: unrecognized command line option ‘-masm=intel’
make[2]: *** [CMakeFiles/pkg_pfs_tool.dir/build.make:63: CMakeFiles/pkg_pfs_tool.dir/compression.c.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:73: CMakeFiles/pkg_pfs_tool.dir/all] Error 2
make: *** [Makefile:84: all] Error 2

To "fix" it, I changed this line in CMakeLists.txt

12 #add_compile_options(-masm=intel -march=native)                                  

And then "make" compiles, but can't link because the architecture is recognized as "linux64":

[...]

make: *** [Makefile:84: all] Error 2

If I force "../thirdparty/lib/darwin-arm64" via CMakeLists.txt, it won't link either:

67 set(THIRDPARTY_LIB_DIR "${THIRDPARTY_ROOT_DIR}/lib/darwin-arm64")                

"make" output:

Do you know how to fix this and add Linux ARM support?

[bucanero]

you need to build your own mbedTLS library for linux arm64, you can't use macOS arm64 libraries.

You need to download and compile mbedtls release 2.27 and in options enable CMAC_C in config.h and also add option -fPIE to CMakeLists.txt in project.
