Hello,

I hope someone can help me getting the freepascal ide compile.
I wrote a simple example hello world to test the ide.
When I try to run the program I get Fatal: Can't find unit System used
by helloworld.

I have also installed Lazarus IDE. Programs in Lazarus compile and run
fine.

I noticed fp putting the fp.cfg, fp.dsk, fp.ini and fp____.err in my
home directory.

Regards,

Marcel

Seems you didn't installed it correctly.  What system are you using?

I use fp 3.0.4 on AntiX linux 19.2.
What files are missing?

Just reinstalled fp, still the same error.
Maybe something is broken in one of the AntiX repository packages.

Did your program explicitly refer to unit system? That is wrong.
Remove any references to system and try again.
System is always included automatically.
If that does not work install with fpcupdeluxe which is the best
option for starters with install troubles.

Just the example from the freepascal wiki:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
Hello;begin  writeln ('Hello, world.');  readln;end.

If that gives you that error your install is really screwed... Try
uninstall (purge) and after that, fpcupdeluxe.

I had the same problem.

I ran "fp" on a machine which has Lazarus installed. Then looked at
Options > Directories. So I added following entries to the fp which
was giving me error.

Units
/usr/lib/fpc/$fpcversion\units\$fpctarget
/usr/lib/fpc/$fpcversion\units\$fpctarget\*
/usr/lib/fpc/$fpcversion\units\$fpctarget\rtl

Libraries
/usr/lib/gcc/x86_64-linux-gnu/9

Attention: Some slashes are forward some are back. Also "build-
essentials" is installed.

I encountered this kind of problem in the past. IIRC, it was because I
installed using fpcupdeluxe and somehow FPC searched /etc/fpc.cfg and
can not found it. I solved it by creating symlink /etc/fpc.cfg and
point it to fpc.cfg from fpcupdeluxe.
