Error when connect to Firebird in Lazarus with Ubuntu lazarus / 16-Databases ---------------------------------------------------------------------- AEslabon4 · 2013-10-30 00:50 Hi fellow Programmers!  I have installed Firebird SuperClasic 2.5 in a computer that have Ubuntu 13.04 64-bit; Lazarus 1.0.12 with FPC 2.6.2 and FlameRobin 0.9.3.2220  When I open my database in FlameRobin there's no problem. I can open the database and make Querys, etc. But when I try to open the same database in Lazarus the program shows me the error:  IBConnection1: DoInternalConnect: -Can't access lock files' directory /tmp/firebird Could this be an error of permissions or owners of the database?  I thank You for the help. ---------------------------------------------------------------------- kpeters58 · 2013-11-14 05:31 You didn't try Google - this was the top result for your error string: https://bugs.launchpad.net/ubuntu/+source/firebird2.5/+bug/678318 ---------------------------------------------------------------------- freeman35 · 2013-11-19 07:31 When install firebird, adding "firebird" grup and user. your user joined "firebird"group too. And check database's permissions too ---------------------------------------------------------------------- exdatis · 2013-11-19 08:46 This is my post on openSuSe forum, I hope will be useful. https://forums.opensuse.org/english/get-technical-help- here/applications/484981-access-denied-firebird.html#post2540698 ---------------------------------------------------------------------- exdatis · 2013-11-19 08:58 Sorry, bad link: https://forums.opensuse.org/english/get-technical-help- here/applications/484981-access-denied-firebird.html Best regards.
