I am trying to compile a gtk program using the tutorial here. When I issue the command
gcc -o tut tut.c $(pkg-config --cflags --libs gtk+-2.0 gmodule-2.0)
I get the following error:
gcc: error: unrecognized command line option ‘-pthread -I/usr/include/gtk-2.0

gcc is version 4.8.2. pkg-config is version 0.26. i have libgtk2.0-dev installed.
I can compile simple c programs fine.
How do I resolve the "unrecognized command" problem?
[update from comment]
I am using zsh.
This looks like a shell issue.
What shell are you using?
In case it's not bash, give bash a try.

im trying to compile a basic code with GTK3+ on Debian11 and i got the following error:
fatal error: gtk/gtk.h: No such file or directory
im using vs code and the autocomplete find the path to the file gtk.h but showme a include errors.
I compile with this command: gcc main.c -o main 'pkg-config --cflags --libs gtk+-3.0'
The output of pgk-config --cflags --libs gtk+-3.0:
:~/Code/GTK/gtkTutorial$ pkg-config --cflags --libs gtk+-3.0

I try to put the complete path in the #include </usr/include/gtk-3-0/gtk/gtk.h> and it give me the next include error for gdk.h file on the gtk.h file.
Both files (gtk.h and gtk.h) exist on my /usr/include/gtk-3.0/gtk/ and /usr/include/gtk-3.0/gdk/ directories.
The code i'm trying to compile is:
#include <gtk/gtk.h>
int main(int argc, char *argv[]) {
gtk_init(&argc, &argv);
// gtk code comes here
gtk_main();
return 0;
}
I don't understand what I'm doing wrong.
any idea, or someone with the same problem?
thanks.
I'm building a program which uses GTK+3 and pango. Most of it compiles fine apart from the last bit which builds the executable. The final command is:
gcc -o z80sim main.c -Wall -Iz80 -Igui obj/disas.o obj/iosim.o obj/sim0.o obj/sim1.o obj/sim2.o obj/sim3.o obj/sim4.o obj/sim5.o obj/sim6.o obj/sim7.o obj/simctl.o obj/simfun.o obj/simglb.o obj/simint.o obj/callbacks.o obj/code.o obj/guiglb.o obj/memory.o obj/flags.o obj/log.o obj/ports.o obj/registers.o `pkg-config --cflags --libs gtk+-3.0`
But I get this error message:
obj/sim1.o: In function `cpu':
sim1.c:(.text+0x2cb): undefined reference to `check_gui_break'
obj/callbacks.o: In function `on_open1_activate':
callbacks.c:(.text+0x20): undefined reference to `Get_File'
:
:
Where check_gui_break is defined and called in sim1.c etc.
This has to be something to do with the ordering of object files and libraries on the ld call, but I have tried putting the pkg-config part before and after the individual .o files and it still gives the same errors.
I've read the very informative https://eli.thegreenplace.net/2013/07/09/library-order-in-static-linking but, although I know a lot more now, I still can't crack this one.
BTW.
pkg-config --cflags --libs gtk+-3.0
gives
-pthread -I/usr/include/gtk-3.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/at-spi-2.0 -I/usr/include/dbus-1.0 -I/usr/lib/x86_64-linux-gnu/dbus-1.0/include -I/usr/include/gtk-3.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng16 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -lgtk-3 -lgdk-3 -lpangocairo-1.0 -lpango-1.0 -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0
Please will some kind soul take pity on me and enlighten me?
It appears that most of the errors I've encountered have been a result of the transition from Glade2 to Glade3. In 2, Glade generates some C code which is what's missing from my code. Back to the reference manual to see how to modernise the code.
I'm new at C and started to learn how to create GUI.
For some reason the only way program run is
gcc simple.c -o simple -lgtk-3 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0 -pthread -I/usr/include/gtk-3.0 -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/pixman-1 -I/usr/include/libpng12
If i just run gcc simple.cit gives me

If I do other 'traditional' ways to include lib:
gcc `pkg-config gtk+-2.0 --cflags` example.c -o example `pkg-config gtk+-2.0 --libs`
It gives me:
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
graphical.c:1:21: fatal error: gtk/gtk.h: No such file or catalog
What is the right way to include GTK?
I just figured out what was the problem.
I had linuxbrew installed and for some reason pkg-config took path from one of it's repos even if I force it to export.
I completely removed linuxbrew and now it's finally working!
Here is the command I use:
gcc -w -g -export-dynamic -o "%e" prog.c `pkg-config --cflags --libs gtk+-3.0 ` `pkg-config --cflags --libs eog`
My program compiles but I get errors from the linker:
undefined reference to `eog_image_new'
Here is the output of pkg-config --cflags --libs eog
pthread -I/usr/include/gtk-3.0 -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/pixman-1 -I/usr/include/libpng12 -I/usr/include/eog-3.0 -lgtk-3 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0
I thought everything was ok since I installed
MinGW
gtk3
gtkmm
cygWin
And I have no problem to compile ordinary simple files. Neither do I have problem with commands such as
$ pkg-config --cflags --libs gtk+-2.0
it outputs

But when I try to compile a simple gtk-app from a tutorial with
$ gcc c_gui.c -o c_gui `pkg-config --cflags --libs gtk+-2.0`
I get an error from the cygwin terminalwindow:
:gcc.exe: error: -LC:/gtkmm/lib: Invalid argument
What could possibly be wrong?
Something seems to be wrong with your pkgconfig. It shouldn't be returning DOS style paths. If I run your exact command above, I get:
-D_REENTRANT -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/freetype2 -I/usr/include/libpng15 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/harfbuzz -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lpangocairo-1.0 -lXinerama -lXi -lXrandr -lXcursor -lXcomposite -lgdk_pixbuf-2.0 -lpangoft2-1.0 -lgio-2.0 -lcairo -lpixman-1 -lGL -lpthread -lxcb-shm -lxcb-render -lXrender -lXext -lXdamage -lX11-xcb -lxcb-glx -lXfixes -lX11 -lxcb -lXau -lXdmcp -lharfbuzz -lpango-1.0 -lfontconfig -lgmodule-2.0 -lgobject-2.0 -lffi -lglib-2.0 -lintl -liconv -lpcre -lexpat -lfreetype -lbz2 -lpng15 -lm -lz
I suspect it's because you're trying to mix MinGW and Cygwin. They don't always work well together.
My /usr/lib/pkgconfig/gtk+-2.0.pc looks like this:
prefix=/usr
exec_prefix=/usr
libdir=/usr/lib
includedir=${prefix}/include
target=x11
gtk_binary_version=2.10.0
gtk_host=x86_64-unknown-cygwin
Name: GTK+
Description: GTK+ Graphical UI Library (${target} target)
Version: 2.24.23
Requires: gdk-${target}-2.0 atk cairo gdk-pixbuf-2.0 gio-2.0 pangoft2
Libs: -L${libdir} -lgtk-${target}-2.0
Cflags: -I${includedir}/gtk-2.0
which looks reasonable to me.
