Two steps i would try: A) File/Clean Directory
B) Run/Clean and rebuild I have a german Lazarus IDE, so the commands perhaps called different! .. never had these sort of issue, never uesed Raspbian Buster good luck John Am 02.02.20 um 23:50 schrieb Bo Berglund via lazarus:
I have encountered a strange problem that was discovered when I moved sources between Windows 10 and Raspbian Buster. It appears that my directory structure does not behave like when I used Delphi... I am using Lazarus 2.0.6 and FPC 3.0.2 in both Windows 10 and Raspbian Buster (on an RPi4B with 4GB RAM). I am working on a webapp (command line program supplying webpages on demand from Apache) as part of a larger system of programs to control hardware through the RPi4. I have used a directory structure where the main control app resides in a top directory with subdirectories for various utilities (like the webapp for configuration purposes). It was started on Raspbian, but I had problems with the Lazarus IDE (it crashes regularly several times a day and then I lose all edits since the last save). So I moved over to Windows and got the sources via Subversion. On Windows Lazarus never crashes. Then I could develop here and use the IDE to check that it builds. I could not use the exe file with Apache because I don't have apache on Windows, but I could work around it and check the output of the webapp anyway using environment variables when I run the executable. So far so good, but to do the tests properly through Apache I moved back to RPi4 (via SVN) and it worked just fine there too. I could make adjustments etc and test via apache that the webapp worked. Then I did a new cycle back to Windows and now something has happened that is a showstopper. If I now open the project in Lazarus and command Compile, build or Quick compile an error is triggered telling me that a file not used by my project cannot find its Linux-only units in the uses clause.... Here the show stops! It complains that it cannot find some unix-only units inside the sourcefile PiGpio.pas, which is used by another project residing one level up in the tree from the working dir of the current project. I have had to add a path to the parent dir (../) in the project options because I need a few common units which define some used classes and these units reside one level up. But these are only 3 units and definitely NOT the units that use PiGpio.pas!!! The unit where PiGpio is in the uses clause is a completely separate source file for another project. Questions: 1) Is it not allowed to use source files *above* the current project dir? 2) If I add a path .. via project properties does this really mean that Lazarus will try to compile ALL source files found there even if only a couple are part of the current project? 3) What can I do to remedy this problem?
