Cannot build GEOS on Windows 10 under MinGW

[twrackers]

New issue: Under MinGW on Windows 10 host, ran following commands.

export PROJECTS=/c/minGW/projects

export GEOS_VER=3.8.1

export OS_BUILD=64

cmake -G "MSYS Makefiles" ../trunk -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX:PATH=${PROJECTS}/geos/rel-${GEOS_VER}w${OS_BUILD} \

-DHAVE_STD_ISNAN=1 -DHAVE_LONG_LONG_INT_64=1 -DDISABLE_GEOS_INLINE=ON \

-DGEOS_ENABLE_TESTS=ON

make

Build terminates with:

I am using the most current MinGW compiler, 9.2.0. How do I fix this?

Sorry, pasted text in original ticket formatted badly. I'm new to this site.

Sorry been distracted of late so just seeing this. I haven't tested with the latest mingw64. I've been using mingw64 gcc 8.1 and msys2.

Which CMake are you using? For some reason I could never get CMake to work with the ones I install in mingw as they seemed to be missing the msys makefiles.

So I always used the 32-bit cmake windows binaries from ​https://cmake.org/download/

I'm currently using the cmake-3.15.4-win32-x86 but the latest on the download site ​https://github.com/Kitware/CMake/releases/download/v3.19.1/cmake-3.19.1-win32-x86.zip should work fine.

I'm guessing the 64-bit would work as well. The main reason I use the 32-bit is so I can use it under my msys 32-bit /mingw64-w32 builders.

My build script looks like this very similar to yours.

export GCC_TYPE=81
  cmake -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=${PROJECTS}/geos/rel-${GEOS_VER}w${OS_BUILD}${GCC_TYPE} -DHAVE_STD_ISNAN=1 -DHAVE_LONG_LONG_INT_64=1 -DDISABLE_GEOS_INLINE=ON  -  ../${CMAKE_GEOS_VER}

I'm using GCC 8.1

Old version, quiet ticket.
