missing binary operator before token "("

sharky · 07-10-2015, 02:33 PM

Seeing this and similar errors when compiling.

Quote:

./iupgtk_webbrowser.c:254:22: error: missing binary operator before token "("

The line in that file is a preprocessor statement.

Code:

#if GTK_CHECK_VERSION(2, 10, 0)

I can modify that statement to clear the error.

Code:

#if GTK_CHECK_VERSION == (2, 10, 0)

However, I do not know if this is the intended functionality.

Hope the issue is stated clearly. Am open to any advice as I am not familiar with gcc and c programming.

#1
What is the name of this unknown program ?
-- a link would help

#2
what version of gcc is being used ?
as in are you trying to build VERY old code with a VERY new compiler

a guess
this is a 3 year old and 3year out of date lua iup
and your version of gcc it way too new for 3 year old unsupported code

smallpond · 07-11-2015, 07:18 AM

Did you do

Code:

#include <gtk/gtk.h>

Yes this is iup (http://www.kiatoa.com/fossils/iuplib) but it's complicated.

I actually started with a project called 'megatest'.

Code:

fossil clone http://www.kiatoa.com/cgi-bin/fossils/megatest megatest.fossil
mkdir megatest ; cd megatest
fossil open ../megatest.fossil

This downloads the megatest project and within that project is a utils subdirectory that has a Makefile. It is that makefile that I am attempting to run.

The make file has a step that uses fossil to clone and open iuplib, then another step that runs a script. The script runs three more makefiles and it is these makefiles that run gcc and generate the aforementioned errors.

It's like peeling an onion.

I do not know much about the code (or c in general) so yes it could be old. I am using gcc 4.8.4.

I appreciate your reply and welcome any other questions or suggestions you might have.

Yes. That line is in the code.

This GTK_CHECK_VERSION macro may not exist before version 3

The compiler returns and error on any GTK_CHECK_VERSION statement regardless of major, minor, or micro numbers.

Well, this works for me:

Code:

$ tail Makefile
gtktest: CPPFLAGS += $(shell pkg-config --cflags gtk+-2.0)
gtktest: LIBS     += $(shell pkg-config --libs   gtk+-2.0)

Code:

$ cat gtktest.c
/* gtktest.c */

#include <stdio.h>
#include <gtk/gtk.h>

int main (void)
{
    printf (
	"compile: ver=%d.%d.%d\n"
	"runtime: ver=%d.%d.%d\n"
	, GTK_MAJOR_VERSION
	, GTK_MINOR_VERSION
	, GTK_MICRO_VERSION
	, gtk_major_version
	, gtk_minor_version
	, gtk_micro_version
	);

#if GTK_CHECK_VERSION(2,20,1)
    printf ("New enough\n");
#else
    printf ("Too old\n");
#endif

    return 0;
}

Conclusion: you didn't quote the very first compilation error message (which was about missing headers) instead picked one at random.

There are no errors about missing headers. I had nine errors and they were all regarding 'missing binary operator'.

What does the rest of your makefile look like?

Here is a complete Makefile that worked for me with the previous example-program:

Code:

gtktest: CPPFLAGS += $(shell pkg-config --cflags gtk+-2.0)
gtktest: LIBS     += $(shell pkg-config --libs   gtk+-2.0)

%: %.c
	${CC} ${CFLAGS} ${CPPFLAGS} ${LDFLAGS} -o $@ $^ ${LIBS}

That returned numerous errors on this end.

Partial return;

I do not have these errors trying to compile the iup code. However the return from make has several -I</some/include/path> options with gcc.

example:

Code:

gcc -c  -Wall -O2 -m64 -fPIC -I../include -I../src -I../src/gtk \
-I/usr/include/webkit-1.0 -I/usr/include/libsoup-2.4 -I/usr/include/webkitgtk-1.0 \

-DNDEBUG -o ../obj/iupweb/Linux30_64/iup_webbrowser.o iup_webbrowser.c

I tested that at work which forces me to use Suse Enterprise Server 11 version of linux. I will try again this evening on my Mint 17.1 home pc.

Thanks,

You should have a libgtk+-2.0.pc file somewhere -- if not, your install might be incomplete

Code:

$ dpkg -S /usr/lib/pkgconfig/gtk+-2.0.pc 
libgtk2.0-dev: /usr/lib/pkgconfig/gtk+-2.0.pc

$ dpkg -l libgtk2.0-dev
+++-==============-==============-============================================
ii  libgtk2.0-dev  2.20.1-2       Development files for the GTK+ library

Reran your test at home on my personal PC and it compiled and ran with no issue.

Still have not solved this.

This is the first error I get.

This is line 586 - 588 from gtk/iupgtk_dialog.c.

Code:

#include <gtk/gtk.h> is the first uncommented line in the file and 'dpkg -s libgtk2.0-dev' indicates that the package is installed.

NevemTeve · 07-31-2015, 05:52 AM

How about doing some research? You could find out where (in which header) is GtkStatusIcon is declared.
