[fpc-pascal]No line numbers shown when Format raises an exception, compiled with -gl
Recently, I have been caught a couple of times by mistakes in my
programs using Format (from SysUtils). When the format string and
the supplied arguments do not match, Format raises an exception.
This is nice, but unfortunately, only a hexadecimal address is printed
when the exception is not caught (my programs do not catch this
exception). All the pieces of these programs have been compiled with
-gl under Linux on i386 with 1.0.10 (actually with ppc386 -vwn -gl -O2
-Sd -Ci -Cr -Co -Ct).
It is a small disaster to find out which Format call is in error, if
you have many of them. How can one get line numbers on the uncaught
exception? Shouldn't a normal backtrace be generated, including line
numbers?
Here is a small program and its response:
[EMAIL PROTECTED](228) cat formatexception.pp
program FormatException;
uses SysUtils; { for Format }
begin
writeln ( Format ( '%S', [ 1 ] ) ) { 1 is not a string --> ECONVERTERROR }
end.

I did make where the source and makefile was; in the /usr/local/src/packages/base/sqlite . Is there a way to invoke it elsewhere? I added -Fi/usr/local/src/fpc-1.9.2/rtl/* to the searchpath in fpc.cfg so it wouldnt complain about finding sysunixh.inc > The missing opcodes are powerpc opcodes.

Simples maybe is to temporarily rename /usr/local/src/fpc-1.9.2/rtl/ to .../rtl2 The FPC makefiles actively search for the RTL root directory when compiling in the tree, and some change in defines or dates might cause them to recompile. You can guard against this by compiling your snapshot with RELEASE=1, which adds a parameter to the buildprocess that signals "never rebuild this" (parameter -Ur) ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

If I change the name to rtl2 won't it err out on not finding sysunixh.inc? I installed fpc 1.9.2 from the beta2 install... this seems to be the problem.. i didnt actually compile fpc. maybe i should pull it from cvs and do a make cycle.
