Hi,
|
|
<BR>
|
|
<P><EM>> I believe this patch should fix both problems.
|
|
</EM><BR>
|
|
<P>That doesn't seem to be sufficient (at least for me). When I compile with
|
|
<BR>
|
|
NDEBUG I get:
|
|
<BR>
|
|
<P>[...]
|
|
<BR>
|
|
microtek.c: In function id_microtek':
|
|
<BR>
|
|
microtek.c:1966: invalid lvalue in assignment
|
|
<BR>
|
|
[...]
|
|
<BR>
|
|
<P>This line is:
|
|
<BR>
|
|
<P> DBG_LEVEL = 1;
|
|
<BR>
|
|
<P>I think this will resolve to (0) = 1;
|
|
<BR>
|
|
<P>Maybe we should do the same as in the case of NDEBUG not set:
|
|
<BR>
|
|
<P>#define DBG_LEVEL PASTE(sanei_debug_,BACKEND_NAME)
|
|
<BR>
|
|
<P>#if defined(BACKEND_NAME) && !defined(STUBS)
|
|
<BR>
|
|
int PASTE(sanei_debug_,BACKEND_NAME);
|
|
<BR>
|
|
#endif
|
|
<BR>
|
|
<P>and set the variable to 0 instead of DBG_LEVEL? I have to confine that I
|
|
<BR>
|
|
don't understand this fully, e.g. the #if defined(BACKEND_NAME) but
|
|
<BR>
|
|
BACKEND_NAME is already used 2 lines before.
|
|
<BR>
|
|
<P><P><P>Further more I get a lot of warnings about empty bodies in if and else
|
|
<BR>
|
|
statements like this one:
|
|
<BR>
|
|
<P>microtek.c:344: warning: empty body in an if-statement
|
|
<BR>
|
|
<P>The corresponding line:
|
|
<BR>
|
|
if (sense[2] & 0x10) DBG(10, "sense: ERR_ILLBPP\n");
|
|
<BR>
|
|
<P>The problem is that DBG is defined to be empty (if HAVE_VARARG_MACROS is
|
|
<BR>
|
|
defined) so the statement resolves to:
|
|
<BR>
|
|
<P> if (sense[2] & 0x10) ;
|
|
<BR>
|
|
<P>
|
|
<BR>
|
|
If it matters, my system is:
|
|
<BR>
|
|
Linux 2.2.14, i386, glibc2.0.7, egcs-1.1.2 and gcc 2.7.2.3
|
|
<BR>
|
|
<P>Bye, Henning
|
|
<BR>
|
|
<P><PRE>
