C++11 and boost::any

Post by ian.rees »

With the -std=c++11 enabled in master, we found a bug in the Boost 1.54 version of boost::any (detail), which is used in the FreeCAD Property system. Boost 1.54 is the default Boost installed in Ubuntu 14.04 (forum thread).

I can see three viable options going forward:

1) Bump minimum Boost version to 1.55 . Shouldn't be much headache for Ubuntu 14.04 users as it's a simple "apt-get install" to upgrade to 1.55, but Ubuntu 12.04 doesn't seem to offer that new of a Boost. We could make the Boost minimum version conditional on the version of gcc used; the older version of gcc in Ubuntu 12.04 doesn't seem to support the part of C++11 that triggers the bug.

2) Use something other than boost::any (which could be a newer version of boost::any packaged with FreeCAD).

3) Forget about this C++11 thing.

Any thoughts? -Ian-

we cannot forget about c++11 anymore, the whole new part design branch uses it extensivly!

I guess one alternative to explore could be adding it to PPA (Ubuntu 12.04) or use this PPA:

I vote for 1). IMHO we'll need to go C++11 one day or another, so we'd better start adapting to it, but we cannot abandon ubuntu 12.04 (it will be supported until april 2017)... For now maybe add some conditions in cmake, so it compiles without C++11 flag on 12.04 and similar (not sure how to detect that, maybe indeed the gcc version). And well... 12.04 users won't be able to use PartDesignNext... Not much we can do about that...

As far as 12.04 goes, I have found a PPA for libboost1.55 and another for GCC4.8 (it also has more recent 4.9 and 5) I did find one site that claimed that the is a incompatibility in the format for GDB version in 12.04 but since it was only one reference and it was a while ago it may or may not be a problem and if it is they had a work around. But I will just try to get FreeCAD to compile with C++11 on 12.04 even if GDB does turn out not to work easily, it would still be progress.

I am doing this now and will come back when done.....

How did you do that? With a PPA or the official 1.55 packages? I tried install the libboost1.55-all-dev package as this is a convenient way to get all boost packages but it came up with an error saying it could not find a dependency which was the equivalent none dev package.

I would also go for option 1). Btw, the PartDesignNexi is this the adjusted PartDesign module or is this a complete new implementation offered as a separate module?

Yep, it was not very easy, in synaptic I show only libboost package, then I select all package with 1.54 and dev and mark it to uninstall.
Then I select all package with 1.55-dev and mark it to install. It automatically add 1.55 non dev package to install.
There is only one 1.54 non dev package that will be uninstalled : libboost-mpi-python1.54.0

this is the PPA to add Boost 1.55 to 12.04,

https://launchpad.net/~boost-latest/+archive/ubuntu/ppa


this is a link to instructions on how to add the PPA for GCC4.8 and importantly how to then configure the system to use 4.8 rather than the default previously installed GCC.

http://ubuntuhandbook.org/index.php/201 ... -04-13-04/

I have not yet looked into how to update Cmake ...if that is also needed...I don't know if it needs to be updated or not yet...does anyone else know?

I have nearly finished the above, I will pull master shortly and do an incremental build .... but I would think I may need to do a full build...anyway back in a bit...
