JUCE compilation error under Windows (Continuous Integration) about libopenshot-audio HOT 2 CLOSED

So, nobody knows? What I found is that in CMakeLists.txt next strings

#### Enable C++11 (for JUCE)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

explicitly adds the "-std=c++11" key into the g++ output command line and thus the -std=gnu++11 (required under MinGW Windows) when specified, was added as two keys: -std=gnu++11 -std=c++11 instead of replace the second one. And definitely, there is no atoll in stdlib when -DCMAKE_CXX_FLAGS="-std=c++11" is used. There is only atol. So, when I removed the mentioned strings from CMakeLists.txt the -std=gnu++11 was automatically added and compilation continues. Edit: it is just enough to comment out the - set(CMAKE_CXX_EXTENSIONS OFF)

Now, I have number of link errors (see below) to zlib.

...
undefined reference to `inflateInit2_'
...
collect2.exe: error: ld returned 1 exit status

Any clues?

I simply tried to follow the wiki instructions to build under the Windows (MinGW) https://github.com/OpenShot/libopenshot/wiki/Windows-Build-Instructions

from libopenshot-audio.

OK. I solved it by renaming static libs C:\msys64\mingw64\lib\libz.dll.a nofile.dll.a and C:\msys64\mingw64\lib\libz.a , thus cmake finds C:/MinGW/bin/zlib1.dll instead.

Edit: the log with all mentioned changes in code:
https://ci.appveyor.com/project/SuslikV/libopenshot-audio/builds/24157962

Edit2: I wrongly used old MinGW 32 from the CI environment, so messed up with the compile and "bitness". By adding C:\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\bin to path - the problem with the zlib linking was solved.

Edit3: even not by adding, just by removing the path to MinGW 32 that I mistakenly added earlier.
