Error install Raudus 0.9.9 on Lazarus 1.4.2 lazarus / 38-Networking and Web Programming ---------------------------------------------------------------------- n3mo · 2015-08-14 16:08 Hi Masters,    I am a Delphi developer for years but I've been away from development, however, i'm going to develop!... seeking alternatives to "migrate" my desktop app got raudus web applications, but also to Lazarus (I did not know). I tried to install raudus but I can not finish installing the package lazarus: - My development environment is on windows 7 64bit. - I installed Lazarus 1.4.2 - I installed Raudus Raudus 0.9.9. - I ran welding.exe, which ended successfully. - I applied the patch to Lazarus in file sourcefilemanager.pas in procedure TryRegisteredClasses - I opened the "RaudusFPC.lpk" package from Lazarus - I started the compilation and this ended successfully. - Finally I started the installation, but this ends with errors do not know how to solve: Construir IDE: Código de salida 2, Errores: 4, Sugerencias: 1 lazarus.pp(41,3) Hint: Unit "redirect_stderr" not used in Lazarus lazarus.pp(142,1) Error: Undefined symbol: PROJECTINTF_TPROJECTFILEDESCRIPTOR_$__SETOWNER$TOBJECT lazarus.pp(142,1) Error: Undefined symbol: CONTROLS_TWINCONTROL_$__GETCHILDSRECT$BOOLEAN$$RECT lazarus.pp(142,1) Error: Undefined symbol: CONTROLS_TCONTROL_$__GETCHILDSRECT$BOOLEAN$$RECT lazarus.pp(142,1) Error: Undefined symbol: GRAPHICS_TCUSTOMBITMAP_$__GETRESOURCETYPE$$PCHAR I find it very interesting and worthwhile project raudus as I would love to use it and spread it, but I worry about its continuity, because it cost me a lot to find information, including wiki's official website is down. ---------------------------------------------------------------------- howardpc · 2015-08-14 17:35 I'm not a Raudus user, so others may offer better help. However, since it is a closed source application, to be able to install successfully in Lazarus both the FPC version and the Lazarus version you are running must match exactly the Raudus package you obtained. Later (or earlier) versions of the compiler or of Lazarus will not be compatible. Could that be the source of your difficulty?
