Hi Martin, nothing worked. I tried to upload the error list, but the moderator blocked the mail: too heavy. I tried to send a smaller mail, than a much smaller one...but it seems that the moderator put me into a black list using the mail subject. I installed version 3.2.2 and it works ok. Definitely something is wrong in version 4.4.

If you want to check, I uploaded the error list you asked for in this google document: https://docs.google.com/document/d/1oyGXtnA0l_NyDj-_yH-oREQliW9s3sAdjSiuio1bWFQ/edit?usp=sharing In the while, version 3.2.2 is just fine for me.

I noticed that the following path is not listed as being searched. C:\lazarus\fpc\3.2.2\units\i386-win32\fcl-db The config is there (listed in the messages) Handling option "-FuC:\lazarus\fpc\3.2.2/units/i386-win32/*" So my guess is that this folder is missing in your install. I just deleted my 32 bit 4.4 install, and installed it again. Using the installer: lazarus-4.4-fpc-3.2.2-win32.exe It does create the above path, and the file "db.ppu" is in that path. You can test it, without having to remove your existing install, by clicking "Create a new secondary installation" when the installer asks for the path. And then install into C:\lazarus2nd And set the config to C:\lazarus2nd\conf So it will not interfere with you other install. If the file is missing - compare the checksum of your download exe https://www.lazarus-ide.org/index.php?page=checksums#4_4 Either with a local checksum tool, or uploading to e.g. virustotal It should also be code signed "Stichting Programming Free Pascal & Lazarus Foundation" - Ensure your local anti-virus has not deleted the files (albeit, I never saw Window defender taking a whole folder, that would be absolutely new) -- _______________________________________________ lazarus mailing list https://lists.lazarus-ide.org/listinfo/lazarus

4. I tried to compile a simple console program that uses IBConnection and I get this error: sqldb.pp(8,46) Error: Can't find unit SQLDB used by IBConnection and unit sqldb.pas is opened :) the error list is: Hint: (11030) Start of reading config file C:\lazarus4.4\fpc\3.2.2\bin\i386-win32\fpc.cfg Hint: (11031) End of reading config file C:\lazarus4.4\fpc\3.2.2\bin\i386-win32\fpc.cfg Free Pascal Compiler version 3.2.2 [2025/11/08] for i386 Copyright (c) 1993-2021 by Florian Klaempfl and others (1002) Target OS: Win32 for i386 (3104) Compiling greenapiworker.lpr (3104) Compiling greenworker_210187.pas (3104) Compiling greenworker_210193.pas (10001) PPU Loading C:\lazarus4.4\fpc\3.2.2\units\i386-win32\fcl-db\sqldb.ppu (10011) PPU Source: sqldb.pp not available (10028) Recompiling SQLDB, checksum changed for c:\lespommesdor\lib\i386-win32\db.ppu C:\lazarus4.4\fpc\3.2.2\units\i386-win32\fcl-db\sqldb.ppu:sqldb.pp(8,46)

ha scritto: OK, first of all "SomeUnit.pas not found" is a sometimes misleading error. in many cases FPC does indeed not see (and should not see) the pascal files. => It should use the precompiled ppu only. E.g. if you use "forms" from the LCL => that is already compiled => only forms.ppu is needed. - FPC is called only with the path of forms.ppu BUT NOT of forms.pas - if forms.ppu is damaged, then you get the error that the pas is not found. Because fpc doesn't stop with "forms.ppu is wrong" it tries to recompile it, it can't and the final error is forms.pas not found. If forms.pas was changed, because its a Lazarus package, the IDE will build the LCL package, - for that FPC will be made to see the pas files - once build the IDE will build the rest, using forms.ppu only ------------------------- fcl-db is FPC => the IDE never rebuilds it. It works only with the db.ppu (and its other ppu). Fpc will never see those sources (the IDE does, but FPC never). But that is not the problem here.

What is it? Why is it there? If you tried to build the file with debug info, then there is a mistake somewhere, and it fails to use it. If you did put "fcl-db" (the sources) manually into some path settings of the project => that also can screw it up. It gets you a 2nd ppu, and that means trouble. Yes, it is possible to selectively rebuild some fpc files (e.g. for debugging)... But, it needs to be done very careful, and the exact steps can vary on which file it is.... And if anything goes just 1% off plan => boom. - sqldb depends on db.ppu - if you rebuild db.pas to a new db.ppu then 99.99% you must also rebuild sqldb (and all other files that depend on it) In theory you can make it so that you rebuild a single ppu only... In theory. -- _______________________________________________ lazarus mailing list https://lists.lazarus-ide.org/listinfo/lazarus

First of all, I tested the above steps (32 bits, on Win10 too) => compiled here. But anyway, please try the following steps - Make a backup of your lazarus.exe ? C:\lazarus\lazarus.exe - Start the IDE - Menu Tools > Configure Build lazarus - Check "Clean all" - Build - Restart the IDE Then try your project again. The above steps will do 2 things. 1) Rebuild the lazarus.exe => you don't need that ? (and in case something goes wrong you can put the backup back) 2) Remove all (most) incorrect ppu, and rebuild most others. ? If you have for whatever reason an incorrect ppu, then that should help. Alternatively: you can check if you have a db.ppu OUTSIDE the c:\lazarus\fpc\........ folder This can happen either, if you had an old install, or if you did change settings on the "path" page of the options. ----- If the above steps do not help: - Open Tools > Configure build Lazarus (again) - Custom option => add:? -va ? (remove that when you finished all the below) - Save (no need to build) - build your project - When the error happens, right click the messages windows, and from the "copy" sub-menu select "copy all and original messages" ? Either zip them, or send the last (bottom most) about 200 of them. -------------- next part -------------- An HTML attachment was scrubbed...

Hi everyone, I am sure this must have been done before. I distinctly remember that at one stage there was a Desktop Environment written for Linux in Pascal (I assumed using Lazarus), but I cannot remember what it was called.

the old version 3.2 works without problems. I love it. I will update when also the new version will work with no problems. I am very grateful to the development team of Lazarus.

Hi Martin, I want to apologize. The problem was due to a very silly reason. A few units of the 3.2 version were copied into a subdir of the work directory. Once I deleted these unwelcome guests, v. 4.2 compiled flawlessly.
