Re: [Lazarus] Question
Thank you for your help. I have found the cause. In version 2.0.12 one can not use TStream.GetSize.

Re: [Lazarus] Question
Thank you once more. It turned out that the problem was not solved. When I have installed new version of Lazarus (2.0.12 instead of 2.0.10), my program failed to work.

[Lazarus] lazarus (2.0.6) on ubuntu 19.10 fails
Hi anybody. I have installed lazarus (2.0.2) . My operating system is Ubuntu 19.10.Earlier lazarus (lazarus 1.8.x? on earlier ubuntu 18.04) was working well. After some progress in developing my program code I have installed a new version and began receiving some strange results. Lazarus writes that it compiles and builds with "sucess" but is 'unable to run "/home/eugen/aux/lmarka/project1"' Has anybody an answer for this problem? -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
