Integrating Crashpad with MacOS Qt application - c++

Our Qt application is built using qmake. We've built Crashpad from this commit which is currently the tip of master. We've linked our Qt application with libclient.a, libbase.a, libhandler.a, libutil.a, Security.Framework and AppKit.Framework and have added the relevant include directories. When we build our application we get the following errors from the linker:

When we investigated child_port_server.o (using nm) we found that the symbol ___MIG_check__Request__child_port_check_in_t was undefined. This lead us back to out/Default/gen/util/mach/child_port_server.c where we found the following:

With limited knowledge of the gen and ninja we attempted to pass the -DTypeCheck flag by modifying util.ninja but this broke compilation. We're stuck and we would appreciate any help the community is willing to provide!
How do we fix the remainder of our linker errors?

We were able to solve this thanks to a response to our post in Crashpad-dev

gtkmm-4.0 will not link on macOS Monterey

I'm having issues getting gtkmm-4.0 to link on macOS Monterey.
I'm trying to compile this example program.
#include <gtkmm.h>
class MyWindow : public Gtk::Window {
public:
MyWindow();
};
MyWindow::MyWindow() {
set_title("Basic application");
set_default_size(200, 200);
}
int main(int argc, char* argv[]) {
auto app = Gtk::Application::create("org.gtkmm.examples.base");
return app->make_window_and_run<MyWindow>(argc, argv);
}
After trying to compile with g++-11 base.cc -o base `pkg-config gtkmm-4.0 --cflags --libs`
I get the following error:

leveled::DB::Open() undefined after I installed leveldb and snappy, macOS

I want to verify the leveldb installation. I have a main function only containing levelDB::DB::Open() function. I installed both snappy and leveldb by using brew install. I have boost 1.67 installed too. I have GCC 8.1. I am running macOS 10.13.5.
my source file looks like this:
int main(void) {
leveldb::DB *db;
leveldb::Options options;
options.create_if_missing = true;
auto err = leveldb::DB::Open(options, "../tmpDB", &db);
if (err.ok()) {
std::cout << "success" << std::endl;
}else {
std::cout << "failed" << std::endl;
}
delete db;
return 0;
}
I compile my code I use g++ main.cpp -lleveldb -lsnappy -o test. The compiler generate the error like:
Undefined symbols for architecture x86_64:
"leveldb::DB::Open(leveldb::Options const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, leveldb::DB**)", referenced from:

ld: symbol(s) not found for architecture x86_64

How can I solve this link error?
You can install leveldb with compiler version.
brew reinstall leveldb --cc=gcc-4.8
Can't link against leveldb on OSX

MacOS ld: symbols not found (x86_64)

I have the following error:
Undefined symbols for architecture x86_64:

I have checked all the similar questions and their solutions but nothing worked for me.
I am trying to test uWebSockets (https://github.com/uNetworking/uWebSockets) and have the following file structure:
my_app (which has main.cpp)
ext/uWebSockets (which is a clone of the repository above)
So, I am doing the following:
~/ext/uWebSockets$ make
make `(uname -s)`
c++ -std=c++11 -O3 -I src -shared -fPIC src/Extensions.cpp src/Group.cpp src/Networking.cpp src/Hub.cpp src/Node.cpp src/WebSocket.cpp src/HTTPSocket.cpp src/Socket.cpp src/Epoll.cpp -stdlib=libc++ -mmacosx-version-min=10.7 -undefined dynamic_lookup -L/usr/local/opt/openssl/lib -I/usr/local/opt/openssl/include -o libuWS.dylib
and obtain libuWS.dylib in /ext/uWebSockets
Then, I do the following:
~/my_app$ g++ -c main.cpp -o main.o -I../ext/uWebSockets/src -I/usr/local/opt/openssl/include -std=c++11
So now I have main.o in /my_app. But when I'm trying to:
~/my_app$ g++ -o start main.o -L../ext/uWebSockets -luWS
I receive the aforementioned error:
Undefined symbols for architecture x86_64:

Here is the same command with -v:

How can I link them correctly?
main.cpp:
#include <iostream>
#include "uWS.h"
int main() {
uWS::Hub h;
h.onError([](void *user) {
std::cout << "WebSocket: Error has occured" << std::endl;
});
h.onConnection([](uWS::WebSocket<uWS::CLIENT> *ws, uWS::HttpRequest req) {
std::cout << "Client established a remote connection over non-SSL" << std::endl;
});
h.onDisconnection([](uWS::WebSocket<uWS::CLIENT> *ws, int code, char *message, size_t length) {
std::cout << "Client got disconnected with data: " << ws->getUserData() << ", code: " << code << ", message: <" << std::string(message, length) << ">" << std::endl;
});
// url, user, headers, timeout, group client
h.connect("wss://www.test.com/", (void *) 0, {}, 5000);
h.run();
std::cout << "Falling through testConnections" << std::endl;
return 0;
}
Finally, I was able to fix it. The problem was in zlib, which I didn't include.
So the correct way of running this is g++ -o start main.o -luWS -lz

You need to link the GLUT framework. In Project Properties > Linker > Command Line > Aditional Options, specify
-framework GLUT
Slight correction in your code:
j = rand() % 3;
and not rand() * 3;. That gives seg fault for obvious reasons.
To complement #user55721's GLUT framework answer, in the context of installing JasPer.
The INSTALL doc mentions an arch specific cmake option to use native GLUT on Mac OS:
When building the JasPer software under Mac OSX, only the use of the
native framework for OpenGL is officially supported. If the Freeglut
library is installed on your system, you will need to ensure that the
native GLUT library (as opposed to the Freeglut library) is used by
the build process. This can be accomplished by adding an extra option
to the cmake command line that resembles the following:
-DGLUT_glut_LIBRARY=/System/Library/Frameworks/GLUT.framework

Those are zlib functions. It seems like it is loading the zlib.h ok, but the symbols aren't being linked in? Just to make sure I downloaded the latest zlib and did a make install, no help. I have no clue what's going on here, it seems like it should be pretty basic, that library is nothing special. Help would be appreciated. Thanks.

I dug into scons to find my answer.
I added this to the SConstruct file (in one of the non-win32 sections):
env['LIBS'] = ['z']
Think this would be worth mentioning to the FCE team or is this something that typically isn't a problem on linux machines?
