I imported Veins5.2 into Omnet++ 6.0 on Windows and when building it shows the following build Error :

Cleaned local , cleane build, still has the same issue
I had build errors also when trying to get Veins running with OMNet++ 6.0 on Windows. See the changelog here: http://veins.car2x.org/download/. Veins lists recommended versions and recommends OMNet++ 5.6.2 instead of 6.0. I had no build errors when using the recommended versions. Good luck!

I want to build grpc to static link library on macOS,my macOS system is macOS Monterey version 12.6(Intel chip).
I found https://chromium.googlesource.com/external/github.com/grpc/grpc/+/HEAD/BUILDING.md#building-with-cmake build shared libraries that is Dynamic-link library，but I want to get static-link library.

How to solve this error? Please help me. Or how to compile grpc to static link library on macOS?
Thanks in advance.
This problem solved by myself,the answer is at https://github.com/android/ndk/issues/1789
I have been struggling with Google protobufs lately. I have written a proto file called Button.proto.
Here are its contents:
syntax = "proto3";
package robotjoystick;
message Button {
string name = 1;
int32 id = 2;
uint32 state = 3;
}
I successfully compiled it with this command (with the $USER replaced with the acctual computer user):
protoc -I=/home/$USER/robotjoystickserver --cpp_out=/home/$USER/robotjoystickserver/proto_classes Button.proto
I am using protobuf version 3.7.1.
My *.cpp file is calleddumbprrotos.cpp and it is not compiling for some reason.
Here is my *.cpp file:

}
The 2 sections of code I have labeled are 2 versions of the same thing that I am trying to accomplish, but both are throwing the same type of error and I have no idea how to interpret it. What do I need to do to make this code compile?
I should also mention that I installed protobuf 3.7.1 right off of my home directory (meaning that the zip file for protobuf was extracted there and then installed there).
The error I get when I currently run the code, the exact way it is, I get this error:

This is the script I am using to compile the code:

echo "Compiling dumbprotos.cpp"
echo ""

I think that is everything I need to show you guys. Did I miss anything? What do I need to do to make my *.cpp code compile?
I am on Ubuntu 16.04.
After thinking about the comment provided by #goduk, I thought I should look further into the linking library issue and find the files I need to source. It turns out that I was not linking to any specific location.
I decided to look through the docs under protobuf-3.7.1/src/README.md to explore further to find the .../lib/ directory. After re-reading those docs, a specific section caught my eye.
To compile a package that uses Protocol Buffers, you need to pass
various flags to your compiler and linker. As of version 2.2.0,
Protocol Buffers integrates with pkg-config to manage this. If you
have pkg-config installed, then you can invoke it to get a list of
flags like so:
pkg-config --cflags protobuf # print compiler flags
pkg-config --libs protobuf # print linker flags
pkg-config --cflags --libs protobuf # print both
For example:
c++ my_program.cc my_proto.pb.cc `pkg-config --cflags --libs protobuf`
On my laptop, the command pkg-config --cflags --libs protobuf returns -pthread -I/usr/local/include -L/usr/local/lib -lprotobuf -pthread.
Instead of trying to determine the correct compiling flags, I simply needed to call the required flags using pkg-config --cflags --libs protobuf at the end.
I had never heard of pkg-config before, but this solved all of my problems.
The final bash script line is now this:
g++ dumbprotos.cpp proto_classes/Button.pb.cc -o ./pleasework -std=c++11 -lSDL2 `pkg-config --cflags --libs protobuf`
Thanks for the help.
(This is a linker type issue.)
I should also mention that, if the protobuf object contains other protobuf objects, you have to include those in the command line call:
g++ my_program.cc my_proto_imported.pb.cc my_proto_containing.pb.cc `pkg-config --cflags --libs protobuf`
Meaning that my_proto_imported.pb.cc is a protobuf imported and used in my_proto_contained.pb.cc.
My first attempt to build uhd was to use a script I had written that had worked in the past on two laptops running 14.04. After that, I went back here:
http://files.ettus.com/manual/page_build_guide.html#build_instructions_unix
After that, I went here:
https://kb.ettus.com/Building_and_Installing_the_USRP_Open-Source_Toolchain_(UHD_and_GNU_Radio)_on_Linux
I get the following compile errors. I'm at a loss, as I have install all of libboost, so I'm not sure what is missing. I'm building on the maint branch. I am on a new computer running 16.04.

I had a similar issue which turned out to be an older version of GCC still installed on my Ubuntu system being called. Look at /usr/bin/gcc and /usr/bin/g++ and see if they're linked to /usr/bin/gcc-5 and /usr/bin/g++-5 respectively.

I've been googling like crazy but can't seem to find a proper solution.
Does anyone know of a language engine (compiler or interpreter, AST, syntax, and basic semantics) but with NO standard library (hopefully not even integers or arithmetic). Is there such a thing? I'd want to be able to implement the standard library in C++. Does such a thing exist?
GCC (and I'm pretty sure a lot of other compilers) lets you build your code without the standard headers and/or libraries, with the -nostdinc (also -nostdinc++ for C++) and -nostdlib flags.
For example:
$ cat t.cpp
#include <iostream>
int main()
{
std::cout << "ouch" << std::endl;
}
$ g++ -nostdinc t.cpp # Failed compilation
t.cpp:1:20: error: no include path in which to search for iostream
t.cpp: In function ‘int main()’:
t.cpp:5:5: error: ‘cout’ is not a member of ‘std’

This is used for building things like kernel code that can't use the C library.
Good luck with implementing a standard library, that's an enormous task.
