You can use -o /dev/null to discard the output altogether, or you could send it to a temporary file which you then delete. If you're concerned with compile times, you can add -E in order to only run the preprocessor, which is the minimum in order for -H to work. That works because if you tell gcc to stop after preprocessing (-H), it doesn't matter if you also tell it to stop after creating an object file (-c). (That's an exception to the general rule that gcc uses the last of a set of conflicting options, which is designed to let you override options by adding to the end of a command-line.)

However, I can't help thinking that this is not really the best solution to your problem. It seems like you've hand-crafted a compiler invocation with a number of options, and then put it somewhere where it's difficult to modify. A better solution would be to use a makefile and set the value of the various standard makefile variables -- such as CFLAGS, CPPFLAGS, LDFLAGS, LDLIBS -- which are documented in the Gnu make manual. In simple cases, your Makefile might consist only of lines which set these variables, since Gnu make has built-in rules for common targets.

You need to add -DGWEATHER_I_KNOW_THIS_IS_UNSTABLE to your C compilation arguments. If you're using Meson, GNOME Clocks has a good example.

Be sure you understand why the library authors make you do this. The library API/ABI might still change in the future, and you may have to update your code accordingly if that happens. (For example, there's an open merge request to remove all the GTK widgets so the rest of the library can link with GTK4 apps).

When you run the command lxc config device add rosfoxy video0 unix-char path=/dev/video0, a device is created in the container with default owner and group. These are root/root. On the host, the group of this device is video but in the container there is no setup to add the non-root user to this group.

Hence, modify the command to the following. The non-root account in the ubuntu:* container image has group ID 1000.

You are asking pkg-config for glib, you must ask pkg-config for the GTK+ library:

There is a particular section in the inkskape documentation about your question

The major steps:

You must update Vim to v8.1 or later.

The wxGtk 2.8.11 cross-build is finally working with the following setup:

I believe the attributes should be a pango font descriptor. You can set the size, family, etc. and then add this to the attribute list. See the following code:

You are missing helloworld.cpp in your Makefile. It should be next to main.cpp
