Compiling on aarch64?

[Ramel]

Hello,

I'm trying to compile on an aarch64 debian 10 machine, but it hangs with :

$ ./build.sh

I've seen this error on another issue with Osx :

https://github.com/CGRU/cgru/issues/317#issuecomment-274172453

But I don't known if it's possible to compile on aarch64 in fact! As I see that all debian packages are in amd64.

Hi! I have not heard that someone managed to compile the project on aarch64. You can also try to ask some special programming on aarch64 forums. It is a very tiny file that produced the error: https://github.com/CGRU/cgru/blob/master/afanasy/src/libafanasy/common/dlCompileAssert.h What's wrong with it for aarch64?

It seem's that if I remove "::" line 15 in cgru/afanasy/src/libafanasy/common/dlCompileAssert.h. It compiles. But don't known why!

 #define compile_assert(expr) DlCompileAssert<(expr)>::assertion_failed();

I don't think that's the solution and as I don't code in C, don't undersand why it's compling! What are the purpose of "::"?

dlCompileAssert.h:15:55: error: ‘assertion_failed’ is not a member of ‘DlCompileAssert<false>

Seems to tell that DlCompileAssert return False but this case is not taken into account in "dlCompileAssert.h". Perhaps an error with compile_assert method. Don't known if it's arm64 or aarch64 related!
