无法使用 minGw64 构建 assimp

Question

我使用了 cmake，并且能够构建一个 C::B 项目。 但是编译 Assimp.cbp 文件引发了一堆错误。 是否有人尝试在 w10 下使用 mingw64 编译 assimp 以便 C::B 向我发送线索？ 提前Thks。 以下是日志错误：

Answer 1

这是我在 MSYS2 下使用 MinGW-w64 构建它的方法：

tar xfz v5.0.0.tar.gz
cd assimp-5.0.0
# fix missing strcasecmp/strncasecmp in code/StringComparison.h (version >= 4.0.0)
mv code/StringComparison.h code/StringComparison.h.bak &&
sed -e "s/strcasecmp/stricmp/g; s/strncasecmp/strnicmp/g" code/StringComparison.h.bak > code/StringComparison.h
mkdir -p build_static build_shared &&
 cd build_static &&
 cmake.exe -G"MSYS Makefiles" -DCMAKE_INSTALL_PREFIX:PATH=/usr/local -DCMAKE_BUILD_TYPE:STRING=Release -DBUILD_SHARED_LIBS:BOOL=OFF -DASSIMP_BUILD_TESTS:BOOL=OFF -DASSIMP_BUILD_ASSIMP_TOOLS:BOOL=OFF -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 .. &&
 cd .. &&
 cd build_shared &&

 cd .. &&
 # fix missing ../../revision.h
 cp -f build_shared/revision.h . &&
 make -Cbuild_static install/strip &&
 make -Cbuild_shared install/strip &&
 echo Success

将/usr/local 替换为您需要的目标文件夹。

虽然我没有成功使用-DASSIMP_BUILD_ASSIMP_TOOLS:BOOL=ON 构建它。

Answer 2

我不知道assimp库，但是如果你使用msys2，你可以使用命令安装完整的包（动态和静态库以及所有头文件）： pacman -S mingw-w64-x86_64-assimp.

Answer 3

据我所知，这些工具目前不适用于此编译器。我需要检查一下。
