When Lazarus reads the config file, what is the current directory (i.e. . in unix and Windows)? Could this be used to specify the same location as the binary? Yes, you can start it with ./lazarus --pcp=config Or under Windows: startlazarus --pcp=config I don't know whether Lazarus does a SetCurrentDir, but in Unix it will be the directory you started it from (if from the shell) or some other directory if started through the desktop manager (I don't know which methods are used there, I'd even need to check what wmii - which is the WM I use - does there ^^). It depends. Desktop shortcuts under Linux have an entry for the working directory. Similar as under Windows. On Windows it will be the directory specified in the shortcut (if started from a shortcut) or the current directory (if started through cmd or by clicking the exe). My opinion: don't rely on the current directory if you want to locate configuration. In theory the approach ExtractFilePath(ParamStr(0)) could be used, but there can be problems on Unix systems with that. Yes, because of bundles, symlinks and shell extensions. The ParamStr(0) is what the user input (e.g. ~/dir/lazarus), not what file was executed.

Re: [Lazarus] Multiple installations
I've always installed Lazarus in the root of the drive, but my projects definitely have spaces in the paths... I have some in C:\user\matt\my docs\some awesome project name\ for example, and it compiles fine. Believe that compiled fine even at 9.22/24 too.
