can't compile with mingw64 #1150

Open Dharmesh946 opened 3 years ago

Dharmesh946 commented 3 years ago

Hi

I tried to compile MRPT on windows with mingw64: I have created a build directory next to the CMakeLists.txt file

cd build
cmake-gui ..
configure
generate
make

I have directly the following error: Building CXX object libs/core/CMakeFiles/core.dir/src/WorkerThreadsPool.cpp.obj In function 'void mySetThreadName(const string&, std::thread&)': error: 'SetThreadDescription' was not declared in this scope SetThreadDescription(theThread.native_handle(), wName);

I can't find any reference to that issue anywhere.

Help would be appreciated. Regards

I'm curious: did you provide opencv or any other dependency? Using any package manager or installer, or building from sources? It's been ages since I last tried mingw64 :-)

I'll look at the build error, I can imagine the reason of this one.

If in the meanwhile you or someone else finds a patch to fix it, feel free of opening a pull request !

Hi,

I compile OpenCV and wxWidgets from sources (with mingw64) and provided them to MRPT. For Eigen3 I'm currently using the embedded version though I've got another one installed. wxWidgets was compiled using instructions from MRPT web site.

Hi!

I fixed all mingw errors I could find. Could you give it a try now, please? (develop git branch)

Dharmesh946 commented 3 years ago

Hi,

Sorry for the delay. I've just tried, same error: In function 'void mySetThreadName(const string&, std::thread&)': error: 'SetThreadDescription' was not declared in this scope SetThreadDescription(theThread.native_handle(), wName); note: suggested alternative: 'SetThreadDesktop' SetThreadDescription(theThread.native_handle(), wName); Regards

Hmm... have you updated your git repository first? Did you check out the develop branch? 🤨 😄

Dharmesh946 commented 3 years ago

Sorry, but yes I did...

D.

FYI, cmake configuration: OpenCV: custom install wxwidgets: custom install following your directives Build type: release custom install directory don't use QT mingw generator

Perhaps an idea: I just happen to realize that my default mingw 64 installation (from https://sourceforge.net/projects/mingw-w64/) does not properly support std::thread. The standard headers are there so my test programs compiles but I've got a runtime error: missing entry point for thread_start. To make my tests works I had to use https://github.com/meganz/mingw-std-threads.git and to modify c++config.h in mingw by commenting the line #define _GLIBCXX_HAS_GTHREADS 1. Eventually, I had to do some magic in my CMakeList files to find mingw-std-threads implementation... It's far from being straightforward. It may be related to the the mrpt compile error (which is thread-related) but it's not clear why. On your side, how do you make std::thread work with mingw 64? huumm, thinking about it while writing... SetThreadDescription is a win32 API? my mingw 64 is posix. I installed also a win32 but don't use it because it does not implement std::thread (if I understand correctly the comparisons I found on the net). So Is it possible to build MRPT with mingw-64-posix, otherwise, do you know how to use mingw-64-win32 AND having std::thread?
