Nightly builds for Linux broken second day in a row

[Rüdiger Franke]

The apts are frozen since March 23.

Fixing this, could you please also add include/omc/cpp/FMU2 to the distribution?

[Martin Sjölund]

It's very easy to fix the nightly builds: by disabling the cppruntime entirely:

[Martin Sjölund]

As for the cpp things, they should be added to:

[Rüdiger Franke]

Better not disable, but fix the cpp things.

I agree that C is more portable. On the other hand side C++ can help to simplify model translation, like keeping track of scoping and object destruction -- hopefully making a garbage collector obsolete. Also note all the array indexing errors in the C runtime (quite a fraction of the tickets deal with this).

It's good to have options.

Should be fixed with r25242. I've used features that are only part of CMake 2.8.11 (17 May 2013) and above, but I think the nightly build server is running with Ubuntu 12.04 LTS or something like that. So there is only an older CMake version installed. Maybe Martin can confirm that.

[Martin Sjölund]

Precise has 2.8.7. Wheezy has 2.8.9. The build server has 2.8.10 everywhere it seems:

$ schroot -a -- cmake --version
cmake version 2.8.10.1
cmake version 2.8.10.1
cmake version 2.8.10.1
cmake version 2.8.10.1
cmake version 2.8.10.1
cmake version 2.8.10.1
cmake version 2.8.10.1
cmake version 2.8.10.1
build@build:~$ schroot --list
chroot:precise-amd64
chroot:precise-i386
chroot:trusty-amd64
chroot:trusty-i386
chroot:utopic-amd64
chroot:utopic-i386
chroot:wheezy-amd64
chroot:wheezy-i386

[Martin Sjölund]

precise-amd64: CMake 2.8.11 or higher is required. You are running version 2.8.10.1

[Rüdiger Franke]

Debian 6 (squeeze) comes with 2.8.2. Debian 7 (wheezy) 2.8.9. The upcoming Debian 8 (jessie) 3.0.2.

Whould be good if not more than 2.8.9 was required.

[Rüdiger Franke]

Just to complete the picture: the current Ubuntu LTS 14.04 Trusty uses 2.8.12. Backports for LTS 12.04 Precise seem to go to 2.8.11 -- meaning that it should be justified to require 2.8.11 if it offers important features.

[Marcus Walther]

Thank you for the information. At the moment we do not really need features of CMake >= 2.8.11 . Instead we are using a feature that is deprecated in CMake >= 2.8.11, but that's not really problematic and it's the price we have to pay, if we want to support a large set of different systems.

However, the nightly build seems to work again, so you can close the ticket now.

[Rüdiger Franke]

Thanks!

Today's nightly is r25243. This is a yesterday's highnoonly. Why isn't the nightly r25263?

GCC 4.6 32-bit issues? Memory issues? Race condition? Who knows...
