Building claws-mail from git master fails currently on Ubuntu 16.04 (no problems on arch linux). [...] pgp_viewer.c: In function ‘pgpview_show_mime_part’: pgp_viewer.c:283:64: error: ‘struct _gpgme_key’ has no member named ‘fpr’ Makefile:697: recipe for target 'pgpcore_la-pgp_viewer.lo' failed Full build log is available at https://ptpb.pw/WuYC.log It seems to have broken after the most recent PGP related commits.
UPDATE: http://git.claws-mail.org/?p=claws.git;a=commitdiff;h=a631e269241b9cb7ff73c00a1980560bb8e7df1b has fixed this. All well again.
