[Solved] Autocomplete gtk3 in vim with YCM results in file not found

newbiehere · 2020-01-29 20:43:27

I am trying to learn gtk3 and I use vim as my daily programming IDE, with YCM. When I enter the following example code I get the error 'gtk/gtk.h' file not found

#include <gtk/gtk.h>
int main (int argc, char *argv[]) {
	gtk_init (&argc, &argv);
        GtkWidget *hello = gtk_message_dialog_new (NULL, GTK_DIALOG_MODAL, GTK_MESSAGE_INFO, GTK_BUTTONS_OK, "Hello world!");
	gtk_message_dialog_format_secondary_text (GTK_MESSAGE_DIALOG (hello), "This is an example dialog.");
        gtk_dialog_run(GTK_DIALOG (hello));
        return 0;
}

I can compile it perfectly well using

gcc main.c `pkg-config --cflags --libs gtk+-3.0`

I can autocomplete the '#include <gtk/gtk.h>' but it becomes '#include <gtk-3.0/gtk/gtk.h>' and results in '#include <gdk/gdk.h> fatal error gdk/gdk.h file not found' error

Including the libs and flags from the command "pkg-config --cflags --libs gtk+-3.0" into the .ycm_extra_conf.py does not seem to change the vim autocompletion at all.

This is the output of "pkg-config --cflags --libs gtk+-3.0"

-I/usr/include/gtk-3.0 -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/lib/libffi-3.2.1/include -I/usr/include/harfbuzz -I/usr/include/fribidi -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/gio-unix-2.0 -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/at-spi-2.0 -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include -pthread -lgtk-3 -lgdk-3 -lz -lpangocairo-1.0 -lpango-1.0 -lharfbuzz -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0

I would suggest you use a compilation database. https://github.com/ycm-core/YouComplete … n-database.

You can create a compilation database with meson build system. In fact, the tutorial page is a example on how to gtk window. https://mesonbuild.com/Tutorial.html#ad … pendencies

Run

meson build

and copy auto-generated compile_commands.json from build directory to source file directory.

Here is the auto-generated compilation database,

[
  {
    "directory": "/tmp/gtk/build",
    "command": "cc -Idemo@exe -I. -I.. -I/usr/include/gtk-3.0 -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/lib/libffi-3.2.1/include -I/usr/include/harfbuzz -I/usr/include/fribidi -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/gio-unix-2.0 -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/at-spi-2.0 -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include -fdiagnostics-color=always -pipe -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -g -pthread -MD -MQ 'demo@exe/main.c.o' -MF 'demo@exe/main.c.o.d' -o 'demo@exe/main.c.o' -c ../main.c",
    "file": "../main.c",
    "output": "demo@exe/main.c.o"
  }
]

    "file": "../main.c",
    "output": "demo@exe/main.c.o"
  }
]

I am able to generate a compilation database that creates a demo file which works perfectly. Now after running

meson build && cd build && ninja

in the project folder, vim no longer spits out errors. It seems to partially be autocompleting since it autocompletes some things I have not even written in the main.c file, or any file for that matter, before. Thanks!

I do however want to run files as usual, I press F6 like this:

map <F6> :w <CR> :!gcc % -o %< && ./%< <CR>

Any idea how to build, link and run the file in vim like this?

I don't have a short cut to run build. For me, I just leave another window open and run ninja there.

But I guess you can do something like this.

First, run `meson build` and copy `compile_commands.json` to your src directory.

With meson build system, you define the binary name in the `meson.build` text file. Give it a name like `app`. Map a key to

ninja -C build &&  ./build/app
