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.
gcc version is
mindgood#minds-MacBook-Pro lib % gcc --version
Apple clang version 14.0.0 (clang-1400.0.29.102)

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 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!
first,I installed google protobuf-3.3 (protobuf-cpp-3.3.0.tar.gz), use xcode to create a crossplatform game project, the target is ios, add libprotobuf-lite.tbd and libprotobuf.tbd, then create a test.proto file like this:
syntax = "proto3";
message Person {
string name = 1;
}
use protoc to compile it to cpp file: test.pb.h,test.pb.cc
when run the project, I got 13 errors:

how to resolve it.. or any other library that supports in iOS8...?
I'm trying to compile the Litecoin source (https://github.com/litecoin-project/litecoin.git). Doing this in windows with VmWare OSX 10.9.1(64bit).
I cloned it and in terminal ran:
make -f makefile.osx USE_UPNP=-
It spits out this error:

make: *** [litecoind] Error 1
I've been googling like crazy but can't seem to find a proper solution.
I am doing a pet project and am using clang++ (specifically MacPorts clang 3.1). So I decided to switch over to libc++ (to use std::array and such) but I was using boost (specifically asio and regex), so I had to recompile boost using libc++. I removed boost which was installed in macports and build boost from source and now is installed in /usr/local/include and /usr/local/lib. Ever since then, I cannot compile. Here are the oddities I am encountering:
When executing:
clang++ -g -std=c++11 -stdlib=libc++ -c main.cpp
I get a weird compile error having to do with the move constructor (there's more to this error, but as you can see it is coming from boost):
/usr/include/c++/v1/string:1952:10: error: overload resolution selected implicitly-deleted copy assignment operator
__r_ = _STD::move(__str.__r_);
^

s1 = traits_inst.transform(a, a + 1);
However, when I execute (please note the "-I", and it must be in that exact position):
clang++ -I -std=c++11 -stdlib=libc++ -g -c main.cpp
This compiles (but linking fails later on). Why is this? What does -I do without a path? Must -stdlib= be preceded with -I?
Now the fun part:
Even though, everything compiles now, it won't link. When executing:
clang++ main.o FTPClient.o FTPConnection.o -lboost_system -lboost_regex -std=c++11 -stdlib=libc++ -g -o cli
I get the message:

Now I am thinking maybe I a missing some -lboost flag but I am not sure what it is. What could be the reason for this?
Thanks very much!
EDIT: When looking through the logs of installing boost, I noticed this:

Does this mean boost regex maybe incompatible with -libc++?
EDIT 2: I tried using std::regex, but I get this:

A helpful, but unsatisfactory answer: libc++ contains std::regex, which you can use instead of boost::regex.
