KC-8.7.1 + vmime-0.9.2k1 compile error

[patrick]

Hi,

On an up-to-date CentOS 7.6 x86_64 box I tried to compile tag kc-8.7.1 against vmime-0.9.2k1 from github.com/kopano-dev/vmime with GCC 8 from the Red Hat developer toolset 8. Compilation fails with the following error (also available at https://paste.centos.org/view/49f2513d):

Anyone know how to fix this error or if it has already been fixed in the KC-8.7.x branch?

If you need more info, please let me know.
Thanks!

Hi @patrick,

to be able to build with this new vime version you also need https://stash.kopano.io/projects/KC/repos/kopanocore/commits/1bbadadf034e6c503788e999e88ef75a3a02f745.

@fbartels Thanks for the quick reply! Will cherry-pick the commit.

Hi @patrick,
is your 0.9.2k1 / 8.7.1 build reasonably stable?
I was experiencing big-issues with current master (8.7.80.1036) though building for CentOS 6 with non-standard php/python and toolchain 7.
At first glance, GDB points in direction of doublefree while cleaning up libvmime-kopano.so.2 (__cxa_finalize).

Resolved:
A version-conflict between libicu-headers and objects was the culprit.
