C Compiler error #4

paulocoghi · 2021-12-02T13:32:57Z

Environment
Ubuntu 20.04 64bit
Crystal 1.2.2 [6529d725a] (2021-11-10)

Installed pre-requisites
sudo apt install pkg-config build-essential libgtk-3-dev libwebkit2gtk-4.0-dev

To execute the first example on readme, on a void directory, I created both shard.yml and a crystal file url.cr with:

shard.yml

name: webview-test
version: 0.1.0
dependencies:
  webview:
    github: naqvis/webview

url.cr

require "webview"

wv = Webview.window(640, 480, Webview::SizeHints::NONE, "Hello WebView", "http://crystal-lang.org")
wv.run
wv.destroy

And shards install goes well:

Resolving dependencies
Fetching https://github.com/naqvis/webview.git
Installing webview (0.1.4)
Postinstall of webview: make
Writing shard.lock

The C compiler error

But when trying to run the example with crystal run url.cr, I get:

Final error

Error: execution of command failed with code: 1: `cc "${@}" -o /home/coghi/.cache/crystal/crystal-run-url.tmp  -rdynamic -L/usr/bin/../lib/crystal `command -v pkg-config > /dev/null && pkg-config --cflags --libs gtk+-3.0 webkit2gtk-4.0` /home/coghi/Projetos/webview-tests/lib/webview/src/../ext/libwebview.a -lstdc++ -lpcre -lm -lgc -lpthread -levent -lrt -ldl`

Please make sure you have required libraries installed. Error indicates that its missing required libraries. Ensure you have libgtk-3-dev installed.

It is installed :(

When using pkg-config to find the gtk+-3.0 library, it finds it:

$ pkg-config gtk+-3.0 --cflags-only-I | sed s/-I//g

/usr/include/gtk-3.0 /usr/include/at-spi2-atk/2.0 /usr/include/at-spi-2.0 /usr/include/dbus-1.0 /usr/lib/x86_64-linux-gnu/dbus-1.0/include /usr/include/gtk-3.0 /usr/include/gio-unix-2.0 /usr/include/cairo /usr/include/pango-1.0 /usr/include/fribidi /usr/include/harfbuzz /usr/include/atk-1.0 /usr/include/cairo /usr/include/pixman-1 /usr/include/uuid /usr/include/freetype2 /usr/include/libpng16 /usr/include/gdk-pixbuf-2.0 /usr/include/libmount /usr/include/blkid /usr/include/glib-2.0 /usr/lib/x86_64-linux-gnu/glib-2.0/include

paulocoghi · 2021-12-03T12:20:10Z

But, I don't know if pkg-config find must also find libgtk-3-dev or gtk+-3.0-dev, because it doesn't:

$ pkg-config --cflags libgtk-3-dev

Package libgtk-3-dev was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgtk-3-dev.pc' to the PKG_CONFIG_PATH environment variable
No package 'libgtk-3-dev' found

$ pkg-config --cflags gtk+-3.0-dev

Package gtk+-3.0-dev was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0-dev.pc' to the PKG_CONFIG_PATH environment variable
No package 'gtk+-3.0-dev' found

paulocoghi · 2021-12-03T12:41:35Z

Important update

I successfully compiled the original examples from github.com/webview/webview, with both Go, C++ and C examples.

Every example compiled and executed perfectly, which helps to conclude that my system is fine.

My only suspicion is that the Makefile may be wrong. I will try to recreate the bindings from the C library, to understand better how the things must be made.

naqvis · 2021-12-04T10:23:55Z

What is the output of command pkg-config --cflags --libs gtk+-3.0 webkit2gtk-4.0 on your system? Also you can download the source code of this shard and just try to perform make on the root folder and see if it get raises any error. This shard has been tested on Mac, Linux and Windows.

No errors when cloning your repo and running make on it:

$ make

I'm unable to reproduce error on Linux (Fedora). Maybe you can try changing the link annotation settings in lib.cr file and do some testing on your box.

Ragmaanir · 2022-03-23T22:20:08Z

FYI: I'm getting the same errors on Linux Mint 20.3 and 19.2 (64bit, crystal 1.3.2, libgtk-3-dev is installed)

FYI: I'm getting the same errors on Linux Mint 20.3 and 19.2 (64bit, crystal 1.3.2, libgtk-3-dev is installed)

Are you getting same error when you separately run make on repo? I don't have access to Linux Mint, so unable to reproduce.

Ragmaanir · 2022-03-24T13:22:09Z

make in crystal webview runs without errors and prints:

g++ -c -o ext/webview.o -DWEBVIEW_GTK=1 `pkg-config --cflags --libs gtk+-3.0 webkit2gtk-4.0` -std=c++11 ext/webview.cc

pedromsilvapt · 2022-07-28T23:02:22Z

I encountered the same issue, but the fix was quite stunning: I just switched the order of the @[Link] attributes for linux (don't know about other platforms) and it worked!

@[Link(ldflags: "`command -v pkg-config > /dev/null && pkg-config --cflags --libs gtk+-3.0 webkit2gtk-4.0`")]
@[Link(ldflags: "#{__DIR__}/../ext/libwebview.a -lstdc++")]

If someone else could validate this change doesn't break anything, it would be great. 😁

paulocoghi · 2022-07-29T08:15:45Z

Thanks, @pedromsilvapt Pedro! I will try to validade this as soon as possible!
