Installs IDE expert which assists to insert JCL Debug information into executable files. This can be useful when use source location routines from JclDebug unit. These routines needs some kind of special information to be able to provide source location for given address in the process. Currently there are four options to get it work: 1. Generate and deploy MAP file with your executable file. The file is generated by the linker. It needs to be set in Project|Options dialog->Linker page, Detailed checkbox. 2. Generate and deploy JDBG file file with your executable file. This is binary file based on MAP file but its size is typically about 12% of original MAP file. You can generate it by MapToJdbg tool in jcl\examples\vcl\debugextension\tools folder. The advantage over MAP file is smaller size and better security of the file content because it is not a plain text file and it also contains a checksum. 3. Generate Borland TD32 debug symbols. These symbols are stored directly in the executable file but usually adds several megabytes so the file is very large. The advantage is you don't have to deploy any other file and it is easy to generate it by checking Include TD32 debug info in Linker option page. 4. Insert JCL Debug info into executable file by the IDE expert. The size of added data is similar to JDBG file but it will be inserted directly into the executable file. This is probably best option because it combines small size of included data and no requirement of deploying additional files. In case you use this option you need install the JclDebugIde expert. The IDE expert will add new item to IDE Project menu. It adds 'Insert JCL Debug data' check item at the end of the Project menu. When the item is checked, everytime the project is compiled by one of following commands: Compile, Build, Compile All Projects, Build All Projects or Run necessary JCL debug data are automatically inserted into the executable. Moreover, for Build and Build All commands dialog with detailed information of size of these data will be displayed. You can generate those debug data for packages and libraries as well using the expert. Each executable file in the project can use different option from those listed above. It is not necessary to generate any debug data for Borland runtime packages because the source location code can use names of exported functions to get procedure or method name. To get line number information for Borland RTL and VCL/CLX units you have to check Use Debug DCUs checkbox in Project|Options dialog -> Compiler tab. Unfortunately it is not possible to get line number information for Borland runtime packages because Borland does not provide detailed MAP files for them so you get procedure or method name only. In case you have more than one data source for an executable file by an accident the best one is chosen in following order: 1. JCL Debug data in the executable file 2. JDBG file 3. Borland TD32 symbols 4. MAP file 5. Library or Borland package exports It is also possible to insert JCL debug data programmatically to the executable file by using MakeJclDbg command line tool in jcl\examples\tools folder. You can study included makefiles which uses this tool for building DelphiTools examples. Short description of getting the JclDebug functionality in your project: 1. Close all running instances of Delphi 2. Install JCL and IDE experts by the JCL Installer 3. Run Delphi IDE and open your project 4. Remove any TApplication.OnException handlers from your project (if any). 5. Add new Exception Dialog by selecting File | New | Other ... | Dialogs tab, Select 'Exception Dialog' or 'Exception Dialog with Send' icon, Click OK button, Save the form (use ExceptionDialog.pas name, for example) 6. Check Project | Insert JCL Debug data menu item 7. Do Project | Build
