restbed static lib with examples - c++

Hi i wanted to compile restbed as a static lib with examples but I have a linker error.
using : ubuntu 16.04 gcc-5.4
What i did:
cd dependency/openssl
./config
*long text*
Configured for linux-x86_64.
*** Because of configuration changes, you MUST do the following before
*** building:
make depend
so i did make depend and make. It made libcrypto.a and libssl.a
So i think this part is ok??
Next
cd build
cmake -DBUILD_TESTS=YES -DBUILD_EXAMPLES=YES -DBUILD_SSL=YES -DBUILD_SHARED=NO -DCMAKE_INSTALL_PREFIX=static ..

It finds the libs so I dont know how to fix the problem.
Update : i installed ssl and crypto libs with
sudo apt-get install libssl-dev
cmake -DBUILD_TESTS=YES -DBUILD_EXAMPLES=YES -DBUILD_SSL=YES -DCMAKE_INSTALL_PREFIX=static ..
Now it works, but when i want to compile an example with https support i still need to link it with -lssl and -lcrypto but that is probably because the ssl and crypto are shared libs.
g++ -std=c++11 -I/home/jova/git/restbed/build/static/include https_service.cpp -L/home/jova/git/restbed/build/static/library -lrestbed -lssl -lcrypto -pthread
How can i get ssl support into the restbed.a static library? Or will i always have to link with ssl and crypto?
I'm confused what does this option -DBUILD_SSL=YES/NO do?

Your issue looks to be a linking problem. Try adding -ldl.
dlopen and friends

How can I successfully Build gRPC in C++?

I am trying to build gRPC in C++ by following c++ gRPC installation. My OS is Ubuntu20.4 LTS installed on Raspberry Pi 4.
When I typed this command "make -j"
$ cd grpc
$ mkdir -p cmake/build
$ pushd cmake/build
$ cmake -DgRPC_INSTALL=ON \
-DgRPC_BUILD_TESTS=OFF \
-DCMAKE_INSTALL_PREFIX=$MY_INSTALL_DIR \
../..
$ make -j
this error occurs.

Please help me to fix this problem.
Can you show what value the gRPC_SSL_PROVIDER variable has? If has module than you just init submodules and build with BoringSSL (see and see). Another option, you can build with OpenSSL, just set -DgRPC_SSL_PROVIDER=package.

QT GStreamer Windows linker problems

I'm trying to compile and run the qml-sink example which is provided inside the gstreamer-good-plugin (QT Example). But currently I get a lot of undefined reference errors during the compile time. It seems that the linker does not link the libraries correctly.
I have checked the list of linked libraries and from my point of view all needed libs are listed.
E.g. gst_object_ref, gst_init, ... are undefined.
My setup:
Windows 10
Qt 5.11
Gstreamer 1.0
Gstremer devel 1.0
Gstreamer plugin good
Installed GStreamer version from here: GStreamer Download => gstreamer-1.0-devel-x86_64-1.14.3.msi and gstreamer-1.0-x86_64-1.14.3.msi
Can anyone please help me, how I can solve this problem?

It looks like you're building for windows. The only way I've compiled the qml plugin on windows is using qmake using the provided .pro file. My experiments with compiling using the mingw toolchain provided by Qt were unsuccessful due to mismatching C++ ABI's between GStreamer and Qt. I ended up using MSVC/Visual Studio for compiling instead.
The undefined references to g_/gst_ probably means you don't have pkg-config setup correctly on your system. pkg-config.exe --modversion gstreamer-1.0 Should output the version of GStreamer you installed.
Where did you download GStreamer from? What GStreamer version exactly? Did you download binaries or did you compile it yourself?

MinGW/CMake Undefined Reference to ZLib

I have a project I want to build with CMake and compile with MinGW. The project uses Zlib. When I build with CMake I get no errors but then when I run MinGW Make it gives the following output:

Anyone have a clue what I can do to fix this? I read that the code can't find the ZLib library, how do I link it?
EDIT here is my CMakeLists.txt. I got this from the Git project.
I just tried to generate a small example to reproduce your errors. I took my test file from the home page of zlib http://zlib.net/zpipe.c
My initial CMakeLists.txt was
cmake_minimum_required(VERSION 3.4)
project(zlib_test)
set(ZLIB_TEST_SOURCES zpipe.c)
add_executable(${PROJECT_NAME} ${ZLIB_TEST_SOURCES})
And I got the same errors

After changing CMakeLists.txt to this form
cmake_minimum_required(VERSION 3.4)
project(zlib_test)
find_package(ZLIB REQUIRED)
if (ZLIB_FOUND)
include_directories(${ZLIB_INCLUDE_DIRS})
endif()
set(ZLIB_TEST_SOURCES zpipe.c)
add_executable(${PROJECT_NAME} ${ZLIB_TEST_SOURCES})
target_link_libraries(${PROJECT_NAME} ${ZLIB_LIBRARIES})
I could compile the program.
So your problem is: Where is ZLIB added in your CMakeLists.txt? At least, you need the line find_package(ZLIB REQUIRED).

OpenGL 4.3 development setup in Ubuntu 14.04

I've just started working my way through the OpenGL SuperBible 6th ed and am having a very hard time getting any of the samples to compile on Ubuntu 14.04. I installed the dev packages dependencies:
sudo apt-get install xorg-dev libglu1-mesa-dev libglfw-dev nvidia-331-dev cmake
I grabbed gl3w from skaslev's github, ran the python script and then sudo copied gl3w.h and glcorearb.h to /usr/include/GL/
I grabbed the samples from the SuperBible github and the media files, unzipped the media files into bin/media. Then I went back to the root of the sb6 files (the folder is called sb6code_2013_11_10 in my case) where and ran:
cmake .
make
cmake works fine, but make throws:

So I decided to try and write my own small program based on Listing 2.1 in the book:
#include "sb6.h"
class my_application : public sb6::application
{
void init()
{
static const char title[] = "OpenGL SuperBible - Listing 2.1";
sb6::application::init();
memcpy(info.title, title, sizeof(title));
}
void render(double currentTime)
{
static const GLfloat red[] = {1.0f, 0.0f, 0.0f, 1.0f};
glClearBufferfv(GL_COLOR, 0, red);
}
};
DECLARE_MAIN(my_application)
Then I try to compile it:
g++ listing2.1.cpp -o listing2.1 -lGL -lGLU -lX11 -lglfw -D_LINUX
But that gives me a different set of errors:

I checked in sb6.h that gl3w.h is included before any of the OpenGL dependencies and that's true so I'll really not sure what to try next. Seems to be a linking problem but it's been a long time since I've been developing in C++ and I'm not sure what to try next.
Update
I followed didierc's suggestion and found that there was a sb6code_2013_11_10/include/GL folder with gl3w.h and glcorearb.h. I temporarily moved the GL folder out of sb6code_2013_11_10/include and then ran cmake and make again and then received the following error:

Then I thought "Ok, then maybe I'll try using the gl3w.h and glcorearb.h that came with the sb6 package." So I restored the GL folder and then deleted the gl3w.h and glcorearb.h I previously generated with the python script and placed in /usr/include/GL. After a cmake and make I then get this error:

So I'm not sure if that's progress but at least is exposes some of the snakes. Any advice on what to do next would be appreciated!

Here's what I get from running make VERBOSE=1 with the GL folder intact (ie just as it was when I downloaded the sb6 files, but I also have glw3.h and glcorearb.h in /usr/include/GL):

Update 3
I was able to find a solution to the build problem with the sb6 sample code. It turns out there is a error in the CMakeLists.txt included with the sample code where on line 13 the 'elif (UNIX)' should be 'elseif (UNIX)'. See references:
trouble trying to build opengl superbible example code
https://github.com/openglsuperbible/sb6code/issues/12
https://github.com/openglsuperbible/sb6code/issues/8
With that fix the sb6 sample code now compiles for me. However, when I try to use sb6.h in my own sample code (listed in my_application above) I still get
In file included from sb6ext.h:29:0,
from sb6.h:71,

I was able to solve the sb6 sample code compilation problems by fixing a bug in CMakeLists.txt where on line 13 the 'elif (UNIX)' should be 'elseif (UNIX)'. See the following for references:
trouble trying to build opengl superbible example code
https://github.com/openglsuperbible/sb6code/issues/12
https://github.com/openglsuperbible/sb6code/issues/8
I have not solve my compilation problems when I use sb6.h in my own code yet but will update this answer when I do

What's the problem?
You are right, the errors are not from the compiler, they are from the linker. Since a lot of the undefined references are about glut functions, first verify that you can link glut properly. Have a look at this link - how to set up Glut.
Most likely you didn't include a header or the include directive in the makefile is wrong because the errors are pretty clear to me: the compiler can't find the core function of OpenGL which are included in the OpenGL headers.
