Summary: Regression - Warning: Couldn't find

Initial Comment:
Whenever I try to compile something (even just an empty file) for z80 or gbz80 I get a

Warning: Couldn't find

message. It does not say what it is that could not be found. If I remember correctly the message appeared with the recent linker/assembler updates.

Message:
Philipp, can you help me to find out what is going wrong?

Add the line in SDCCmain.c:
printf("%s\n", dbuf_c_str (&crtpath));
at lines 1812 and 1840, immediately after lines:
dbuf_printf (&crtpath, "%s%s%s", s, DIR_SEPARATOR_STRING, *p);

This will print all paths where cdr0.rel is searched.

Borut

and go step by step

Hmmm...

What does "sdcc --print-search-dirs" say?

Message:
It wasn't the latest snapshot. Now I get a much nicer

Warning: couldn't find crt0.rel

I still don't know why I get this warning at all though:

> ls /usr/local/share/sdcc/lib/z80/
crt0.rel  z80.lib

Message:
I think I already fixed this one:

2010-02-18 Borut Razem <borut.razem AT siol.net>

	* src/SDCCmain.c: search C runtime initialization object files
	  crt0.rel in system library directories, then in user defined
	  library directories

"Couldn't find" meant that sdcc couldn't find the crt0.rel file, but the
file name was not written by mistake.

Philipp, can you please verify if you are using the latest svn snapshot?
