invalid use of non-lvalue array w/ GCC 3.3.5

[Papp Gyozo (VBuster)]

Hi,

I've encountered the following problem with GCC 3.3.5:

cmdline.c:2242: invalid use of non-lvalue array
cmdline.c:2242: invalid use of non-lvalue array
gmake: *** [cmdline.c.o] Error 1
gmake: Leaving directory 'vbscan/build'

the corresponding lines from cmdline.c:

2237:  if (args_info->daemon_mode_counter && args_info->standalone_mode_counter) {
2238:    error += check_modes(
2239:      (int []){args_info->daemon_given, args_info->attach_given,  -1},
2240:      (const char *[]){"--daemon", "--attach",  0},
2241:      (int []){args_info->engine_given, args_info->vdb_given, args_info->optional_given, args_info->quarantine_given, args_info->temp_gi
2242:      (const char *[]){"--engine", "--vdb", "--optional", "--quarantine", "--temp", "--scanning", "--heuristics", "--memory", "--archive
  }

I'm about to update GCC but there is no other way to solve this?

sorry, it is even worse for me, we still use 3.0.4 shame on me!
btw, my question is still open.

Hi

can you try to solve the problem manually, so that I can rewrite the
generation code accordingly?  Probably those arrays should be declared
explicitly, but you should try until you don't get errors anymore, since
I don't have that version of the compiler...

thanks
hope to hear from you soon
cheers

Is there actually no ending " after "--archive , or did my mail client
bugger it?

Yes, sure I'll give it a try as soon as I have time to play with it. I was wondering if there was any barrier to do it other way (explicit decl as you suggested) and beside this hoping someone pointed me out what this error message complaining about specifically, because first I couldn't see what left-value it was speaking about...

don't worry! It was me who forgot to copy the whole line from the stderr.
no closing " in the original message either.

yes I could generate explicit declaration but I'd want to be sure
whether this solves the problem, because this would require some work in
the code generation :-)

as for the error, I can't see the l-value either, so it looks like a bug
in the compiler... :-D

Yes, it solved the problem. I manually edited the generated source (see the diff for details) and reran GCC once more. Now it compiled the source even with no warning.

I still don't know. The first not affected GCC version I found is 3.1. 3.0.4 seems buggy or rather I don't know something...

glad to hear that :-)

so I think I'm ready for this bug-fix release, and then I can start
working on new features.
