New installed FPC on Linux, I got this:-(

Something wrong with the configuration file (/etc/fpc.cfg or
~/fpc.cfg), most notably the -Fu line that points to precompiled
units.

What actually gave that message? I assumed a commandline compiler, but
did you by any chance tried the textmode IDE ?

----------------------------------------------------------------------

I use the texmode FPC

And Free Pascal Deluxe do(this seems to work, but not the TEXT FPC)

The textmode IDE needs to configured separately. Normally a distro
package would prepare that, but just go to options->directories and
then in the "units' tab put something like


 -Fu/usr/lib/fpc/$fpcversion\units\$fpctarget
 -Fu/usr/lib/fpc/$fpcversion\units\$fpctarget\*
 -Fu/usr/lib/fpc/$fpcversion\units\$fpctarget\rtl

coradi · 2024-09-21 19:12

?? What is differend tom the existed Version from top?
It seems the same

----------------------------------------------------------------------
marcov · 2024-09-21 19:16

The textmode IDE has its own configuration and doesn't read fpc.cfg

The *.cfg generator also has a textmode IDE part, but apparently it
isn't called for your distro's package.

----------------------------------------------------------------------
coradi · 2024-09-21 19:18

ahh,  I have different FPC on my system.
The FPC in FPC Deluxe works well, now only the lazarus in FPC Deluxe
have the same error

----------------------------------------------------------------------

From what I have seen, this problem [sometimes|usually] relates to an
unexpected fpc.cfg somewhere. Or an unreadable one on Windows (because
of inappropriate coding, I spent a few hours there yesterday!).

Given the frequency of this problem, displaying the path to fpc.cfg on
a fpc -h page would be cool as would showing it in the Options page
for Lazarus.
