[SOLVED] Why does $fpctarget not work in fpc.cfg?

[Gustavo 'Gus' Carreno]

Hey Davo,

Gus, like I said, in verbose mode, you should see (a whole lot of stuff including) the compiler parsing the config file and then searching, in what it thinks is the right place for eg units. If you have replaceable parameters in the cfg file you will see it looking in the place it derived by putting that parameter into the config line in question.  Here is an example (64bit linux of course) 

Code: [Select]

dbannon@dell:~/Pascal/CLI$ fpc -va tsetdemo.pas > dump.txt
dbannon@dell:~/Pascal/CLI$ ls -l dump.txt
-rw-r--r-- 1 dbannon dbannon 462519 Jul 16 10:30 dump.txt
dbannon@dell:~/Pascal/CLI$
Some interesting lines from dump.txt , note number on left is a line number added by my view utility, you may not see that -

Code: [Select]

OH CRAP!!!

I was doing:

Code: Bash  [Select][+][-]

1. fpc -va dummy.pas | grep -i 'fpctarget'

It never occurred to me, to look for the resolved paths DOH !!!!!!!!!! :hard-facepalm: :hard-table-headbut:

Now I have to redo all my effing tests!!!

Many thanks for the hint, will test and come back to apologise for wasting so many people's time due to my own very high stoooooooopidity !!!!!!!!!

Jesus Gus!!! Get a bloody grip !!!

Cheers,
Gus

The documentation for the fpc.cfg configuration file lists a "#WRITE" directive that can be used to get the value:

Code: [Select]

#WRITE TARGET=$fpctarget

You will see this in the output (or in the Lazarus "Messages" window) during compilation.

Hey n7800,

Code: [Select]

#WRITE TARGET=$fpctarget


Thank you soooo, soooo much for this tip !!!
This is exactly the debugging nifty trick that I needed for my niche case!!!
Cannot thank you enough, seriously!!

Cheers,
Gus

Code: [Select]

#WRITE TARGET=$fpctarget


wow, n7800, that is so useful !  Thanks !

Nice, PascalDragon has filled in the missing information (my guess was pretty bad). PD, how do you know those parameters ?  Is it doc'ed somewhere or you looked (or wrote) in the code ?

I looked at the code. Was quicker considering I have Lazarus with the compiler open anyway.
