Hello,

I have updated to Lazarus 1.6 and fpc 3.0 and I get the same error
messages:
- Configure Lazarus IDE window: fpc compiler: /usr/bin/fpc, Error:
fpc.cfg is missing
- Error: Compiler /usr/bin/fpc does not support target i386-linux

I do not cross-compile. Simly from Linux gtk2 32 to the same.
All works fine, but this two error messages occur. I have checked the
Tools-Options directory entries. I know there are a lot of threads
about this subject, some of them were my own questions. But they do no
help... I remember I had this problem already with former updates.

Can you type fpc -i in a terminal and report back what targets the
compiler says it supports? You probably have a wrong compiler.. 64bit?
In that case you need to build a crosscompiler for i386 or have a
double installation for 32 bit and 64bit, which is possible, provided
some additional measures. (multiarch)
Multiarch may or may not be already installed, but just in case :
http://askubuntu.com/questions/454253/how-to-run-32-bit-app-in-
ubuntu-64-bit the answer specifies how to do that for Ubuntu, bu that
also works for debian jessie..

Additional info: I have got an Ubuntu 32 bit version 12 installed.

fpc -i   says:
Free Pascal Compiler version 3.0.0

Compiler date      : 2015/12/05
Compiler CPU target: i386

Supported targets (targets marked with '{*}' are under development):
  Go32v2: GO32 V2 DOS extender
  Linux: Linux for i386
  OS2: OS/2
  Win32: Win32 for i386
  FreeBSD: FreeBSD/ELF for i386
and so on.

Seems all OK.

fpc.cfg files are here:
/home/martin/fpc.cfg
/etc/fpc.cfg
/usr/bin/fpc.cfg

Then I have also set the PPC_CONFIG_PATH variable.

My own apps work fine (besides the two error messages), but I cannot
compile a lpk file: The target is WINCE is set (the last target in the
target list). I can see this because it tries to compile these OS
specific units.

I have tried to set the target in the project options, no effect.

Even in my own apps which I can compile, the compiler directives ar
wrong in the editor: {$ifdef unix} is grayed. It seems that the editor
also shows WINCE target.

I am not sure WINCE for intel32 is supported. If that is what you are
trying to do.
AFAIK it is still WINCE for ARM only, for which you need a cross-
compiler.

If that is NOT the case, the fpc.cfg is corrupted or from a wince/arm.
You can remedy that by creating a new one: delete the old one and use
fpcmkcfg >fpc.cfg to create a new default one.
It will set the correct values for your platform. Maybe you have to
add some -Fu's and -Fi's  for Lazarus.

I could fix the problem now. Even a sudo apt-get remove fpc, fpc-src,
lazarus and a reinstal via deb packages had no effect.

It seems that the ~/.lazarus/environmentioptions.xml file was
corrupted and forced the wrong target and the missing fpc.cfg file.
The ./lazarus directory is not overwritten or deleted when
reinstalling or uninstalling Lazarus.
