使用 Code::Blocks 和 MinGW 构建 Assimp

Question

I am trying to build Assimp with Code::Blocks and MinGW as a static library. I have downloaded the latest available version (5.0.1) and created a makefile for Code::Blocks using cmake-gui. I am able to open that file with Code::Blocks, but when I am trying to build it fails. Here is the complete log:

I am not really familiar with all that build stuff, but it looks like there is some problem with zlib. How can I fix that problem and build the library with the compiler I have?

I don't want to switch to msys2.

Answer 1

Latest assimp version at this time is 5.1.6 , so it looks like you're a bit behind.

That version builds with MinGW-w64. I build it using CMake and Ninja. I use the following CMake flags: -DASSIMP_BUILD_ASSIMP_TOOLS:BOOL=ON -DASSIMP_HEADERCHECK:BOOL=OFF -DASSIMP_OPT_BUILD_PACKAGES:BOOL=OFF -DSYSTEM_IRRXML:BOOL=OFF -DASSIMP_BUILD_SAMPLES:BOOL=OFF -DBUILD_DOCS:BOOL=OFF -DASSIMP_BUILD_TESTS:BOOL=OFF -DCMAKE_CXX_FLAGS:STRING="-Wno-array-bounds -Wno-alloc-size-larger-than -Wno-error=array-compare"
