I'm building a golang project by using Go1.12 + msys2/mingw-w64(9.2.0), it shows errors:

After some research I'm sure it's a msvcrt compatibility issue of mingw64.
I know there are workarounds like this: unresolved external symbol __imp__fprintf and __imp____iob_func, SDL2
But it doesn't solve all of my issues.
I try to link the library: LDFLAGS: -L%filepath% -llegacy_stdio_definitions, nothing changes.
Is there a patch to fix it, or do I have to build my custom version of mingw64?
So I answer my question by myself, the case is closed.
Yes, Mingw64 uses msvcrt.
Here are some tips that could help to solve dependency problems between Mingw64 & msvcrt.
The major goal is to let compiler load the correct version of MSVCRT library family.
1.Update Mingw64.
2.Check out MSVCRT_VERSION in Mingw64\include_mingw.h(or x86_64-w64-mingw32\include), make sure the version number matches your windows version, or modify it.
3.Take a look at linker option like "#cgo LDFLAGS: -Lxxx", don't mess the library path. Remove any unnecessary library path setting, let linker finds libraries itself.
Make sure everything is built with same libraries.

I'm trying to take advantage of some of OpenSSL's EC cryptography and ECDSA functionality to make a rudimentary blockchain simulation, but I've run into a major roadblock. I'm using the Code::Blocks IDE, and I've installed OpenSSL using the 64-bit binary found here: https://slproweb.com/products/Win32OpenSSL.html.
In Linker Settings, I added OpenSSL-Win64\lib\openssl.lib
In Search Directories > Compiler, I added OpenSSL-Win64\include
In Search Directories > Linker, I added OpenSSL-Win64\lib
However, when I compile, I get the "undefined reference to (function name)" error for every OpenSSL function I try to use. However, the compiler seems to be successfully including the header files, since it recognizes the new data types like EC_KEY. I suspect a linking error, but I'm not sure what could be wrong, since I have the link paths and static library linked as above.
Here is my build log:

I'm hoping I'm just missing something simple here since I'm new to linking static libraries. A lot of similar issues seem to be solved by adding options to compile commands, but since I'm using Code::Blocks and linking OpenSSL as a static library, I'm not sure if those apply here. Any help is greatly appreciated.
Figured it out. The issue was that I had no C:/MinGW folder (as Code::Blocks installed MinGW within its own directory). I'm guessing the binary I used tries to detect existing compilers and compiles the library differently depending on what it finds.
I fixed it by installing default MinGW (with MSYS, in case that matters) with the default path (C:/MinGW) and then reinstalling the 32-bit binary OpenSSL linked in the original question, also in the default path (C:/OpenSSL-Win32). This made it so that within the C:/OpenSSL-Win32/lib folder, there was a new MinGW folder which I then included in the linker search directories.
Encountering "boost::filesystem3" undefined reference errors while trying to link:
RawStreamReader.cpp:(.text._ZNK5boost11filesystem34path4leafEv[_ZNK5boost11filesystem34path4leafEv]+0x1f): undefined reference to `boost::filesystem3::path::filename() const'
This is on Linux 64.
I rebuilt the boost 1.55 with same c++11 options that I am using for my build.
The output from this symbol dump seems to indicate that none of the symbols contain "filesystem3" in the name (the 3 part is missing).
Note, that I have read these questions / answers (to no avail):
Failed at linking C++ [undefined reference boost::filesystem3 ... ]
c++ boost::filesystem undefined reference to `boost::filesystem3::path::root_name() const'
The code is compiling on other systems against same boost version. This is a fresh install with a new cmake build setup that I am trying to debug. All other boost libraries seem to be linking fine.
as a project of my own, I'm writing a refactoring library (so it can by used by other applications) using libclang for code analysis.
The problem is when i try to compile my program to a static library everything is okey, but when i try to link my library (using some clang code) with some demo application (just main function calling my code) the linker is reporting:
./librefactor.a(renamer.o):(.data.rel.ro+0x60): undefined reference to 'clang::ASTConsumer::HandleInterestingDecl(clang::DeclGroupRef)'

Here is a makefile I build my library with: library makefile
Here is a makefile I build an example with: library example
I commented out some parts of the code to make the error as short as possible but they are some similiar errors (undefined reference) from other part of clang i use in my project.
Problem is I don't understand why linker can't find definitions of these functions/methods. They are not pure virtual in base class so I don't need to defined them. As I see it the linker is trying to find the definition of these in my part of the code istead in clang binaries. Could somebody please explain me where I'm wrong here and explain/repair it?

I am using mingw 4.5 and g++ 4.5.2 on windows. Boost version v1.4.8.
I hope someone can help me solve this problem.
Thanks.
It looks like you aren't linking to the boost libraries.
Boost doesn't come with windows since it isn't a standard library. You've got to download the headers and libraries, then include the headers in your project and link to the libraries at compile time. Since you're using g++, this means adding a -l line to your compile command. The -l line must be used with each specific library you want to use also, you can't just specify the boost directory.
This page will help you get started on Windows and this page will help you get started on *nix platforms.
Once you've compiled boost, then in your example, you should compile your program with
g++ -o tester.exe -Lpath/to/boost/libraries/ -lboost_thread tester.c
Make sure you've got all your libraries linked properly.
Try putting this line first if your thread library is statically defined
#define BOOST_THREAD_USE_LIB

I'm trying to set up libusb API on my OS. I downloaded libusb api on libusb.org. I followed the standard installation procedure:
cd into directory
./configure
make
make check //without errors
make install
Then I launched Eclipse C/C++ and copied some code from the tutorial found on the internet. But when trying to build it I got following output:

I have libusb.so in /lib and also I have usb.h in /usr/local/include and the link for the .so and libusb.a in /usr/local/lib.
Also the #include inside the code is correct.
I know that problem is in linker but I, kind of, cannot make it work :)
I'm using Fedora 15 operating system and gcc 4.6.0 20110603 (Red Hat 4.6.0-10) version compiler.
So what could I do to resolve these undefined references? Thanks very much for help :)
I did face the same problem. But I was able to solve it by adding '-lusb-1.0' to the linker.
e.g : g++ myfile.cpp -lusb-1.0
you have to set the library linker flag for compilation in the linker,
you can get a full list in the console by executing
pkg-config --list-all
These are the libraries which you have installed on your system and you have to link against the ones you want to use.
so in your example it is libusb so you do
pkg-config --libs libusb
there should be the output
-lusb
or
-lusb-1.0
This gives you the flag you have to pass to the linker. e.g.
g++ myfile.cpp -lusb[-1.0]
Then you edit the configuration of the project and search for the linkerflags, there should be a textfield for that somewhere in the buildoptions. i'm not quite shure where to find it but googling for it suggested:
Project -> Properties -> C/C++
Build -> Miscellaneous -> flags
After you found it, just add the linker flag in the textfield and you should be fine.
EDIT
since my answer is the accepted one, I also added the other flag that seems to work for a lot of people.
What is your linker command line? You need to have -lusb in the linking command; just having the header included won't work.
I don't use Eclipse C/C++ but I am pretty sure the reason is the same that I faced some while ago when setting up a C project in Netbeans.
It's not enough to have the #include in your code and the library at the right location - you also have to tell Eclipse where to look for them and how to use them. This turorial shows you how to set it up in Eclipse.
