Can the required libstdc++ version be lowered? about openblok HOT 9 CLOSED

I've managed to make it work only with C++11, using Boost.Regex on 14.04. Unfortunately Boost also causes the generated AppImages to be more than twice as big, around 20 MB. It seems to depend on the ICU Unicode libraries, that are almost 30 MB uncompressed on their own.

Ok, patches merged, and I'll likely set up a continuous branch later as well. Will keep you updated.

Ok, there's now a continuous release, updated on every commit.

Thank you, added to AppImage/appimage.github.io@0cd5f42.

Even with update information, cool!

OpenBlok uses some C++11/14 features, which were first implemented in GCC 4.9.0 (libstdc++ 3.4.20), eg. std::regex and std::make_unique. Some functions work differently (eg simply return false in 4.8), or have a different syntax between the two versions. I'm not sure if it'd be possible making it work with earlier libstdc++, without rewriting some parts of the code or adding new dependencies.

On the other hand I wonder if creating a static build would work? That is, building on Ubuntu 14.04, but using GCC 4.9 from the Ubuntu dev PPA.

Hm no, static build probably won't work either...

Are these C++11/14 features really needed?

from openblok.

Yes, but with some workaround I think I can add 4.8 compatibility. The main problem is the regex library, but I can add a wrapper layer that'd use eg. Boost.Regex on 4.8. I use some minor C++14 features like std::make_unique, but likely those can be replaced as well.

I think that's an acceptable price to pay for now.
