Problem compiling laz_fpspreadsheet_visual.lpk lazarus / 49-FPSpreadsheet ---------------------------------------------------------------------- straetch · 2016-06-17 10:29 I upgraded to Lazarus 1.6.0 with FPC3.0.0. (32 bit version). This went smoothly. Then I wanted to upgrade to the latest fpspeadsheet (version 1.6.2 on sourceforge), to overwrite the existing version. With lazarus package -> open package file, I selected laz_spreadsheet_visual.lpk. When I compile the package I got a fatal error: Compile package laz_fpspreadsheet 1.7: Aborted Compile package TAChartLazarusPkg 1.0: Exit code 1, Errors: 1 tagraph.pas(25,3) Fatal: Cannot find Graphics used by TAGraph, incompatible ppu=C:\Software\lazarus\lcl\units\i386-win32\graphics.ppu, package LCLBase My first idea was to ask for advice from the LCL group, but then I saw the difference in version numbers of fpspreadsheet (1.6.2 on sourceforge vs. 1.7 in the error report). Could that explain the "incompatible ppu" message? What can I do? Windows 7,  Lazarus 1.6.0 with FPC3.0.0. (32 bit version). ---------------------------------------------------------------------- wp · 2016-06-17 11:10 There are many possibilities of what may go wrong. Since recompilation of Lazarus for the installation of the visual fpspreadsheet package does not find TAChart, and since you seem to have a mixup of fprspeadsheet versions I think it would be easiest to do a radical cut. Rename or delete your Lazarus folder and the fpspreadsheet folder, as well as your user profile folder (normally c:\users\\appdata\local\lazarus) (I'd prefer renaming in order to be able to revert). Then make a new installation of Lazarus and fpspreadsheet. I don't see a reason why this should go wrong. Regarding fpspreadsheet, please note the version 1.6.2 is the latest released version and 1.7 is the current development version. I'd recommend to install 1.7 because it fixes some bugs of 1.6.2, has some new features, and the wiki documentation refers to it. If you don't use svn you could download the snapshot from https://sourceforge.net/p/lazarus-ccr/svn/HEAD/tree/ and extract from the zip file only the fpspreadsheet folder in components. If you'd prefer fps1.6.2 you find the download at https://sourceforge.net/projects/lazarus- ccr/files/FPSpreadsheet/fpspreadsheet-1.6.2.zip/download. ---------------------------------------------------------------------- straetch · 2016-06-17 16:49 A good cleanup did the job. Works like a charm. Thanks for your advice and detailed directives.
