Foonathan Memory error when compiling Fast-DDS：The following configuration files were considered but not accepted

[Vermounthlly]

I have installed Fast-CDR ，ASIO， foonathan_memory_vendor，but can't install Fast-DDS

This is the Terminal error：
`- Setting build type to 'Release' as none was specified.

Can anyone suggest what mistake I'm doing in these steps. Thanks！！！！

Hi @Vermounthlly,

Could you please provide us more information about your environment? Reading the traces, it seems that you are building for an ARM architecture... Are you crosscompiling?

[Vermounthlly]

Thank you for your reply!!
Yes,I'm trying to cross compile Fast-DDS using x86_64_arm-linux-gnueabihf-gcc-4.9.0 ,and got that error.

This is System information:
Ubuntu 18.04
Fast-DDS Version 2.7.0
Asio Version 1.22.1

By the way, I got this error, and then I changed the cross-compiler------ aarch64-linux-gnu-gcc version 8.4.0
also has another error:

I don't know how to solve these problems......

[Vermounthlly]

I have fixed the problem. I used the wrong compiler version
