#1619 Regression - Warning: Couldn't find

[Philipp Klaus Krause]

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.

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?

Borut

[Philipp Klaus Krause]

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

Hmmm...

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

> sdcc -mz80 --print-search-dirs
programs:
/usr/local/bin
datadir:
/usr/local/bin/../share
/usr/local/share
includedir:
/usr/local/bin/../share/sdcc/include/z80
/usr/local/share/sdcc/include/z80
/usr/local/bin/../share/sdcc/include
/usr/local/share/sdcc/include
libdir:
/usr/local/bin/../share/sdcc/lib
/usr/local/share/sdcc/lib

[Borut Ražem]

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

[Philipp Klaus Krause]

With the two lines added:

> sdcc -mz80 test.c
test.c:1: warning 190: ISO C forbids an empty source file
/usr/local/bin/../share/sdcc/lib/crt0.rel
/usr/local/share/sdcc/lib/crt0.rel
Warning: couldn't find crt0.rel

[Borut Ražem]

Fixed in svn revision #5703.

Philipp, thanks for helping me. Can you please try it?

Borut

[Philipp Klaus Krause]

Now I have

> sdcc -mz80 --print-search-dirs test.c
programs:
/usr/local/bin
datadir:
/usr/local/bin/../share
/usr/local/share
includedir:
/usr/local/bin/../share/sdcc/include/z80
/usr/local/share/sdcc/include/z80
/usr/local/bin/../share/sdcc/include
/usr/local/share/sdcc/include
libdir:
/usr/local/bin/../share/sdcc/lib/z80
/usr/local/share/sdcc/lib/z80
test.c:1: warning 190: ISO C forbids an empty source file
Warning: couldn't find crt0.rel

The libdir search path has changed, but I still get the warning.
I have compiled and installed from a fresh checkout of #5703.

[Borut Ražem]

Philipp,

the library search pathe now seems OK.
Can you please retry it with added lines:
dbuf_printf (&crtpath, "%s%s%s", s, DIR_SEPARATOR_STRING, *p);
as before?

Borut

[Borut Ražem]

... you are right, I'm an idiot!

Philipp, if you still have nerves, you can try it once more.

Thanks for your patience,
Borut

[Philipp Klaus Krause]

Thanks, It does find crt0.rel now.
