I'm installing Gearman 1.1.12 on Windows 8.1 through Cygwin and getting the following error:
CXX libtest/libtest_libtest_la-formatter.lo
In file included from ./libtest/test.hpp:69:0,

from libtest/formatter.cc:39:
./libtest/exception.hpp:83:13: error: 'va_list' has not been declared
void init(va_list);
^
I've verified that the source code has the necessary includes and that the GCC/G++ compilers are the latest version, 4.8.2
Any ideas on how to fix this?
I had this problem today and it was "fixed" by including <cstdarg> on libtest/test.hpp.
Did you check that?
(Wanted to reply as a comment, but I don't have enough rep yet)

anyone know how to fix it ,I'm using the mingw to compile it.
Probably your MinGW is broken. Also, GCC 6.3.0 is very old.
Try a more recent MinGW or even better MinGW-w64.
A standalone build is available from http://winlibs.com/ with GCC 10.2.0 (both for Windows 32-bit and 64-bit).
I am trying to compile the Arduino Tensorflow lite Library example file for Arduino Due board, but at the time of compilation I got error of missing cmsis_compiler.h file error. I also tried to compile the code for STM32F103C8 board on Arduino version 1.8.12 with the Arduino_TensorFlowLite at version 2.1.0-ALPHA-precompiled library but still the same error.

I can understand that may be the Arduino Due is not officially supported but I think the STM32F103C8 board is supported. So is there anything which I am missing here?
I hope you have found an answer yourself since posting this question, but for anyone else fumbling their way in here; it seems like the current tensorflow-lite library (as I'm writing this it is: 2.1.0-APLHA-precompiled) only works with MbedOS-boards (Portenta H7 and Nano 33 BLE).
Hope you could use this answer :D
I'm trying to compile the EOS blockchain/smart contract project on GitHub on Ubuntu 14.04:
https://github.com/EOSIO/eos
After getting Clang 4.0 to install, installing build_essentials, and upgrading CMake to 3.5, I was able to run the build process without any missing dependencies. However, now I get the errors shown below when I build the EOS source. This seems to me like another general issue with the configuration of the tools on my system since many people are able to compile the EOS code, although usually on Ubuntu 14.04.
Can anyone tell by looking at the errors I'm getting what tool or library I need to install or upgrade?

The Missing _t alias names look like you’re having issues with C++14. The header paths in the error messages look like you’re using the standard library from GCC 4.8 (the default compiler on Ubuntu 14.04), which is simply too old.
I can see two solutions:
Switch from GCC’s libstdc++ to an up-to-date version of LLVM’s libc++. I’m not familiar enough with Ubuntu to tell you how to install it. For the compilation of EOSIO you must pass the -stdlib=libc++ option to Clang to switch to the different stdlib. EOSIO looks like it’s using CMake, so you have to include -DCMAKE_CXX_FLAGS=-stdlib=libc++ in your CMake command line.
Use the Toolchain test builds PPA to install a newer GCC and and libstdc++ in addition to your system’s default one. For Ubuntu 14.04 GCC 7.2.0 is the latest version available, which is perfectly C++14 capable. Add the PPA to your package sources and then do a:
sudo apt-get install gcc-7 g++-7
This installs both the GCC C compiler and C++ compiler along with the stdlib. Your default compiler is still going to be the old GCC 4.8, so you’ll have to tell CMake about the newer versions:
-DCMAKE_CXX_COMPILER=g++-7 -DCMAKE_C_COMPILER=gcc-7
Note that now you compile EOSIO with GCC (and the new stdlib) instead of Clang. Instructing Clang to use a specific version of libstdc++ should be possible, but I don’t know how.
Official support is for Ubuntu 16.10. Consider upgrading.
(EDITED: I mistakenly said 14.10)

I'm trying to build OpenCV 3.2.0 vc14 from its sources with MinGW 5.3.0 32 bit in order to use its functionality from Qt 5.8. My platform is Windows 7 64 bit.
The main instruction I follow is here, on Qt's wiki. On several steps, I encounter errors for which I haven't found solutions yet. As I am a newbie, I apologize for my helplessness and will appriciate any suggestions.
Error 1. On the stage of generating build files.
In cmake-gui (cmake-3.2.1-win32-x86), I precisely follow the steps specified in the Qt wiki article mentioned above. However, during the final generation, the following CMake error occurs at the end:
CMake Error in modules/highgui/CMakeLists.txt:
No known features for CXX compiler
"GNU"
version 5.3.0.
Generating done
I wonder how it affects the project files and if it causes the next errors.
Error 2. When trying to build OpenCV
The build process is interrupted midway, logging the following:

NOTE: I also had sprintf() family security error. So I followed Alex's suggestion to add add_definitions(-DSTRSAFE_NO_DEPRECATE) to the beginning of CMakeLists.txt to suppress the error.
Thank you for your time.
I'm working on my coin at the moment, following the guide posted here:

I've used the same libraries, installed them correctly -- everything! However, I get the following error during compilation.

mingw32-make: *** [build/bitcoin.o] Error 1
After reading on bitcoin forums, I found a post by shakezula that mentioned this was frequently a result of missing "__NO_SYSTEM_INCLUDES". However, that is included in my .pro file, which you can find here:
http://pastebin.com/4p4BMPAE
Thanks for your help.
I managed to fix this by downloading the CoinLab build environment; for those interested, the QT version was 4.8.4, with MinGW as the version bundled with GCC 4.6.2.
I'm right where you are when you posted this atm. Kinda stuck here as well... Are you using Qt 5.2? I think we may need to use 4.8.5 to get anything done.
