I promise, it is the last for tonight.
It would be wonderful if in /compiler/globals.pas, at line 906, you add this
line (or something like that):
{ Replace some macros }
Replace(s,'$FPCPATH',AnsiString(IncludeTrailingBackslash(ExtractFilePath(ParamStr(0);
So in fpc.cfg you may do:
-Fu$FPCPATH/units/$fpctarget
-Fu$FPCPATH/units/$fpctarget/*
-Fu$FPCPATH/units/$fpctarget/rtl
And it works like charm.
@Jonas, I apologize, really, you kindly answered but I feel alone against a

Re: [fpc-pascal] Search path order for fpc.cfg
Hello Alexander. Thanks for the tips, but all that is too much complicated for a totally newbie. I did not really understand the argument that is a absolutely wrong way to store the fpc.cfg in the same directory as the compiler, like it is allowed for Windows. But I accept the choice. With the patch, I agree, it is maybe to simple, unzip it, compile it, no script needed, no break of compatibility (even I would prefer change the search order), the fpc.cfg is in the directory of fpc and all the -Fu's are like -Fu./units/ to point to child directories.

Re: [fpc-pascal] Search path order for fpc.cfg
Are you always going to be running the compiler from a front-end (IDE, whatever else)? Just use code on the other end to find the binary directory and call something like "fpc @/home/whereis/fpc/fpc.cfg ..." You could also use a bash script to wrap the compiler and do something like: https://stackoverflow.com/questions/59895/how-to-get-the-source-directory-of-a-bash-script-from-within-the-script-itself#59916 To find out where the script is (and therefore where your binaries/config are) to use with @ again. I duno. If you really do this I'd suggest doing it once and writing a correct config to .fpc.cfg in their home directory... in that case they can at least upgrade fpc independently from the whole project.

Of course if you can show me a trick for configuring a script that will install fpc in the home directory (.fpc.cfg), with for example the hard-coded directory /home/user/instantfpc, I will use it. But the condition will be that the user has nothing write, only run a script. The default install.sh used by FPC calls samplecfg to create the config file for the compiler. samplecfg is located in compiler/utils. Line 40 and following contain: # Detect if we have write permission in sysdir. if [ -w "$sysdir" ] ; then echo Write permission in $sysdir. fpccfgfile="$sysdir"/fpc.cfg fppkgfile="$sysdir"/fppkg.cfg defaultfile="$sysdir"/fppkg/default compilerconfigdir="-d CompilerConfigDir=$sysdir/fppkg" fppkgconfdir=$sysdir/fppkg/conf.d else echo No write premission in $sysdir. fpccfgfile="$HOME"/.fpc.cfg fppkgfile="$HOME"/.config/fppkg.cfg defaultfile="$HOME"/.fppkg/config/default fppkgconfdir="$HOME"/.fppkg/config/conf.d fi So as you can see, when the user does not have write permissions in /etc or /local/etc, it will write a config file in the user home directory, exactly where the compiler will pick it up. So you see, we've covered the situation you are trying to solve. It has been so for ages, all you need to do is use what is there correctly. There is no need to change anything.

As I said, all programs that work like that ask you to execute some script (in your .bashrc or .cshrc) to set some environment variable. You can simply do the same, or as Alexander points out, use the provided installer script from fpc. You reason from a windows perspective. This is seldom a good idea on Unices.

> There's a prompt in the freepascal installer that asks for the prefix. Your users should be capable of that? As explained in previous post, the goal is to not touch the system. If you use the fpc installer, even if you install it in the user's home directory, the installer will create a fpc.cfg in /etc and that needs root access. Of course users can do that but the goal of that patch is to have a compiler totally out-of-the-box, that even dont need to configure or set anything. Sorry but not all users are gurus.

Even if you ignore the above cases and only care about the directory in which the binary was found when it was started, then there is still the issue that not all Unix systems provide you with that information. E.g. on Darwin/macOS, if you just type "ppcx64", then the "full path" to the binary that the program gets is "ppcx64" and you have no idea where it's located. You can use some heuristics like looking in the path, but this is fragile and might possibly even be used for attacks (it is probably possible to specify a different PATH environment variable to the child process than the one used to originally find it). This is also the reason why most Unix programs have there installation directory compiled into the binary, and why you often have to specify it already when building the program (rather than only when installing it). FPC does not do that due to its DOS and OS/2 heritage, but it's not something we should extend. In short: the installer should write a 'correct' config file, without tricks like relative paths. Many unix programs that can be installed 'anywhere' require you to set environment variables in order to find where you installed it.

So I propose to do this, dont hurt existing code, only gives happiness: That will not happen. -Fu./something Can *already* be specified and means relative to the CURRENT working directory, not the compiler binary directory. Your patch would change this behaviour, and that is not backwards compatible. You can do -Fu$PPC_CONFIG_PATH/../units/whatever (or any other environment variable) The compiler accepts this. We can add some extra macros there if you want, but we will not change the behaviour of ./ See also https://www.freepascal.org/docs-html/current/user/userse18.html#x52-590005.3 But based on this and your other questions, IMO your reasoning is fundamentally wrong, you should never rely on the compiler location. Instead maybe you should explain what the actual problem is you are tying to solve, then we can help you better instead of explaining what cannot or will not be done.

According: https://wiki.freepascal.org/Configuration_file Under a Unix or Unix-like operating systems (e.g. FreeBSD, Linux) 1)The current directory. 2)Your home directory, it looks for .fpc.cfg. 3)The directory specified in the environment variable PPC_CONFIG_PATH, and if it is not set, it will look in the etc directory above the compiler directory. (For instance, if the compiler is in /usr/local/bin, it will look in /usr/local/etc) The directory /etc. Would it be possible to have a 4th: the directory of the binary compiler and maybe change his order? No. That is not backward compatible. In the worst case we can add the compiler dir, but as the last. But even so: it is not done on unices to search in the binary directory for config files. That's a windows thing. Don't introduce this on unices: You should accept & follow the rules of the platform you're working on. If you really want that, create a wrapper which sets PPC_CONFIG_PATH to the compiler bin dir. But I strongly advance against this. Does fpc accept relative path for -Fu in the fpc.cfg config file, something like: -Fu../units/$fpctarget -Fu../units/$fpctarget/* -Fu../units/$fpctarget/rtl Yes.

My guess is you have a config file lying around that causes this to look

Try -var to see why.
