rebuild IDE not work with modified TDBF lazarus / 31-LCL ---------------------------------------------------------------------- powerpcer · 2023-01-03 01:12 i had add one function to TDBF in public section, rebuild IDE  goes well. when i use those new function, IDE shows correctly. but when i build project, IDE shows Error: identifier idents no member am i missing something? ---------------------------------------------------------------------- wp · 2023-01-12 17:28 What did you change? Note that the TDbf code belongs to FCL, which means that you must rebuild FPC so that your changes are effective. This is different from purely-Lazarus based packages where it is sufficient to rebuild the Lazarus IDE.
