[SOLVED] gcc doesnt detect header files in /usr/include

Red_S2 · 2023-08-09 10:06:42

gcc `pkg-config --cflags gtk4` main.c `pkg-config --libs gtk4`

returns gtk/gtk.h: No such file or directory

The files exists, the directories listed by pkg-config contain those headers, yet gcc, cc and clang cant find them.
If #include "/usr/include/gtk-4.0/gtk/gtk.h" is utilized it fails to detect the files required by gtk.h

What does

pkg-config --cflags gtk4

return?

mpan · 2023-08-09 11:31:29

I can’t reproduce this. In addition to what solskogen asked for, please provide the output of:

pacman -Q gtk4 gcc

and the simplest possible, minimal, valid⁽¹⁾ source code depicting the issue.

Note⁽²⁾ that “/usr/include” is special only to the includes, which are specified directly relative to it. Otherwise it is unimportant if the file is in some directory under “/usr/include” or elsewhere.
____
⁽¹⁾ That is: not your current source code.
⁽²⁾ The note included due to how the thread title is formed, suggesting a possible misconception about “/usr/include”.

Why would you use that line? That makes pkg-conf irrelevant and makes the code not portable. While this is not the cause of your current issue, the include line should be "#include <gtk/gtk.h>"

$ pkg-config --cflags gtk4

current source code:

#include <gtk/gtk.h>

int
main (int argc, char **argv) {
  GtkApplication *app;
  int stat;

  app = gtk_application_new ("test", G_APPLICATION_DEFAULT_FLAGS);
  stat =g_application_run (G_APPLICATION (app), argc, argv);
  g_object_unref (app);
  return stat;
}

I'd add the following:

pacman -Qkk gtk4

Trilby: I believe they used the complete path include for testing purposes only.

Red_S2: There is a reason I was very precise with the source code request and even urged you to not post your current code. Please do not do this again, if you receive such a request. It serves a specific purpose.

In either case, I still can’t reproduce the issue. The code compiles and links just fine.

You did not post the output of `pacman -Q gtk4 gcc`. But, since you did not post it yet, please include Trilby’s request, and the output of one more command:

pacman -Q gtk4 gcc
pacman -Qkk gtk4
which gcc

What's your interactive shell?
What if you manually substitute the backtick-ridden `pkg-config --cflags gtk4`with the literal "-I/usr/include/gtk-4.0 -I/usr/include/pango-1.0 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/cairo -I/usr/include/graphene-1.0 -I/usr/lib64/graphene-1.0/include -mfpmath=sse -msse -msse2 -I/usr/include/harfbuzz -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/gio-unix-2.0 -I/usr/include/blkid -I/usr/include/pixman-1 -I/usr/include/libmount -I/usr/include/fribidi -I/usr/include/libxml2 -I/usr/include/sysprof-4 -pthread -I/usr/include/libpng16" (w/o the quotes)?

loqs · 2023-08-09 15:08:12

If it is not the process substitution please post the output of the compile command with -v option added.

Red_S2 · 2023-08-09 15:19:50

I am using the fish shell, for doing so i have to replace ` with brakets, I check that the out put is right before posting.

It runs in bash, it was the shell

Scimmia · 2023-08-09 15:24:24

It seems to be passing the output as a single entity instead of splitting in on whitespace. This is a fish problem, I'd bet it works fine in bash.
