How to build oatpp on arm64？

[weidqi]

Do I need any special parameters to compile oatpp on arm64? I compiled it as usual and only saw warnings but no static library was generated.
Would you do me a favor?
Thanks!

I build oatpp with aarch64-linux-gnu, arm-linux-gnueabihf;
build it with xilinx sdk 2018.3 arm32 and aarch64 ;
build it with zig build system arm32 and aarch64;

You must prepare openssl aarch64 , cmake 3.20+ and aarch64-linux-gnu first.
Ubuntu20.04 64
aarch64-linux-gnu-g++-10

oatpp src code in dir "oatpp-aarch64"

mkdir build-aarch64

make && make install
running...
...................................ok

but..... the executable I compiled on aarch64 did not run successfully.
On arm32 with xilinx 2018.3 is success.

with zig build system build oatpp success. build executable success. but run server program crash!
malloc(): corrupted top size
at this code
AppComponent components;

So, I don't know if oatpp really supports the aarch64 platform.

I hope it helps.

By the way, I think you've compiled it. You just can't find the compiled library file!

[weidqi]

Yes, the static library was not generated. Thank you for your help, I will try the method you suggested.

[wlfsky]

"Cmakelists.txt", find
option(BUILD_SHARED_LIBS "Build shared libraries" ON)
set to
option(BUILD_SHARED_LIBS "Build shared libraries" OFF)
build.....
it build static library.

[weidqi]

Yes, using your method, the compilation for arm64 was also not successful. It is possible that it is not supported after all.
