I encountered a very similar issue with a project I help maintain, where I fixed some issue in a unit but that unit was not automatically recompiled after being changed. I had to clean and rebuild the project. As you say, this is not extremely expedient. My apologies for not keeping more details, but I was quite happy to have gotten it working at the time.

The 'Other unit files (-Fu)' paths are usually empty. It is not empty if a package has multiple source directories. You should add all source files to the package.

[Lazarus] Compiling/linking/debugging package with generics
Hi All! I have been having a problem for a long, long time when developing/debugging code which is included in a *package* and which contains *generics*. It took me years :'(, but I finally figured out what I was doing so that I could cause the issue to appear consistently. :-[ My usual debugging process is: 1. Edit the library code 2. Compile/Run 3. Debug. My current insight is: What would happen was that changes made to the library code would compile, but not be included in the code which specializes the generic item. When I entered the debugger, I could see the newly changed code, but single-stepping *ignored* my changes. If I let the program run without debugging, the resulting behavior was the *same as it was before the edit*. I have a work around for this (when I remember to use it): 1. Edit the library code 2. Compile the package 3. Use *Run | **Cleanup and build ...* 4. Debug TL;DR Library packages which declare generics do compile, but do not get included in the code that specializes them unless I "Cleanup and build" the whole program. (Workable, but much *slower* than programs without generics). I searched the bug tracker, but did not see anything resembling this problem. I would submit a bug report but I'm not sure whether this is an IDE problem, a package problem or a compiler/linker problem. Would someone more familiar with this part of the architecture give me pointers?
