Re: [Lazarus] Can't compile Lazarus on Linux Mint 15
The problem was introduced with revision 25766. You can fix the problem simply getting an earlier revision in a new folder and copy the older revision cairo units over the trunk copies. Assuming you are one directory above your fpc folder ... svn co -r 25764 http://svn.freepascal.org/svn/fpc/trunk/packages/cairo/srccairofix rm fpc/packages/cairo/src/*.pp cp cairofix/*.pp fpc/packages/cairo/src/ rm -rf cairofix cd fpc make clean make all On Sun, Oct 20, 2013 at 2:33 PM, silvioprog wrote: > 2013/10/20 Reinier Olislagers > [...] > >> You could check if any of the solutions here >> http://bugs.freepascal.org/view.php?id=25191 >> work for you and/or contribute a fix... > > > Unfortunately I don't know how to fix this problem. :( > > But if someone has the same problem, and lost your environment that was > working, here, I made a backup copy that Lazarus and Free Pascal works fine: > > https://www.dropbox.com/s/3z5r4rxeuws1hol/freepascal.tar.gz > > https://www.dropbox.com/s/6icvwp0qeilka9l/lazarus.tar.gz > > -- > Silvio Clécio > My public projects - github.com/silvioprog > > -- > ___ > Lazarus mailing list > Lazarus@lists.lazarus.freepascal.org > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > > -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Debug builds only work as root
I have been trying Ubuntu 13.10 this weekend and I'm hoping someone can advice on a Lazarus issue I'm experiencing. This version of Ubuntu come with gdb 7.6.1. When using Lazarus and debugging the compiled program frequently locks up. Launching Lazarus with sudo or gksudo (in a launcher) fixes the problem. All files modified by Lazarus with sudo are owned by root and I have to keep 'chown -R myusername .' whenever I want to using thse files outside of Lazarus. So the question is, how can I either downgrade gdb to a version which works nicely with Lazarus and not hose the rest of my system? Or how can I fix Lazarus to not lockup programs which are run with debugging? -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
