Do we have a C++11 compatible compiler for OS4?

Postby softwarefailure » Sat Mar 17, 2018 1:40 pm

AFAICS the latest SDK comes with gcc 4.2.4 which doesn't support C++11. Is there anything newer available? I think we'd need at least gcc 4.8 for proper C++11 support.

The adtools repository contains the latest GCC 5.4

https://github.com/sba1/adtools

There is a semi official set of builds here:

https://dl.bintray.com/sba1/adtools-native/

be careful about installing the coreutils in those packages, as of 2017 they were incorrectly built against newlib and so broken.

I notice there is a now 2018 archive, not investigated that yet.

C++ 11 is generarlly supported but some parts such as threads may not be. Also dynamic linking can be problematic due to libstdc++ name clashes with the existing OS version. Static is fine though.

Thanks. I don't need threads or dynamic linking so it should be fine.

Unfortunately, it doesn't work. I tried both the oldest (18/02/17) and latest (29/01/18) of the packages from your link but they both don't work.

Here is what I get:

This doesn't look like it is anything that I could fix. It looks like something in the compiler setup is broken, doesn't it?

I compile like this:

Code: Select all
gcc -c -std=c++11 -o test.o test.cpp

I'm not a C++ expert but I think it's to do with strict interpretations of standards. Using --std=gnu++11 instead gets you what you need.

No, it's a wide char issue. Seems like the OS4 gcc doesn't support wide chars at all. Let's hope they can fix it.
