Displaying the message at the correct location would be more involved... you might want to open a bug report for that so that it's remembered somewhere, but it's definitely going to be a low priority one.

For me a dialog with the following text appeared: "A generic declared in the interface section of a unit must not reference symbols that belong solely to the implementation section of that unit."

The errormessage is probably technically correct, but for me it might be a little more informative (so that I can tell what I did wrong). -- Bart ___ fpc-devel maillist - fpc-devel@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel

Hi, While trying to solve https://bugs.freepascal.org/view.php?id=38306 I got this error I have never seen before. _gdeque.pp(249,4) Error: Global Generic template references static symtable _gdeque.pp(302) Fatal: There were 1 errors compiling module, stopping Fatal: Compilation aborted Line 249 is the "end;" of a method (IncreaseCapacity) of a generic class. If I remove this line the error goes away: Elems := Min(EmptyElems, FStart); Elems and EmptyElems are local vars to that method. FStart is a private variable of the class. function Min(const A,B: SizeUInt): SizeUInt; //no need to drag in the entire Math unit ;-) begin if (Ahttps://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
