Question

我是OSG＆amp; CMake，我正在尝试按照README文件中的指定构建适用于iOS的OpenSceneGraph。以下是平台和工具规范。 MAC OSX 10.10.4 XCode 6.4 iOS 8.4 iOS模拟器8.4 OpenSceneGraph 3.4.0-rc9 CMake 3.3.0

重现错误的步骤： 1：修改并保存OSG文件夹中的CMakeLists.txt 选项（OSG_BUILD_PLATFORM_IPHONE＆＃34;启用IPhoneSDK设备支持＆＃34; ON）选项（OSG_BUILD_PLATFORM_IPHONE_SIMULATOR＆＃34;启用IPhoneSDK模拟器支持＆＃34;关闭）

2：在CMake GUI更新中＆＃39;源代码在哪里：＆＃39;和＆＃39;在哪里建立二进制文件：＆＃39;到OSG文件夹。设置以下选项。

OSG_BUILD_PLATFORM_IPHONE：BOOL = ON \
CMAKE_CXX_FLAGS：STRING =＆＃34; -ftree-vectorize -fvisibility-inlines-hidden -mno-thumb -arch armv6 -pipe -no-cpp-precomp -miphoneos-version-min = 3.1 -mno-thumb＆＃34 ; \
BUILD_OSG_APPLICATIONS：BOOL = OFF \
OSG_BUILD_FRAMEWORKS：BOOL = OFF \
OSG_WINDOWING_SYSTEM：STRING = IOS \
CMAKE_OSX_ARCHITECTURES：STRING =＆＃34;用于ARMv6; ARMv7的＆＃34; \
CMAKE_OSX_SYSROOT：STRING = / Applications / Xcode.app / Contents / Developer / Platforms / iPhoneOS.platform / Developer / SDKs / iPhoneOS8.4.sdk \
OSG_GL1_AVAILABLE：BOOL = OFF \
OSG_GL2_AVAILABLE：BOOL = OFF \
OSG_GLES1_AVAILABLE：BOOL = ON \
OSG_GL_DISPLAYLISTS_AVAILABLE：BOOL = OFF \
OSG_GL_FIXED_FUNCTION_AVAILABLE：BOOL = ON \
OSG_GL_LIBRARY_STATIC：BOOL = OFF \
OSG_GL_MATRICES_AVAILABLE：BOOL = ON \
OSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE：BOOL = ON \
OSG_GL_VERTEX_FUNCS_AVAILABLE：BOOL = OFF \
DYNAMIC_OPENSCENEGRAPH：BOOL = OFF \
DYNAMIC_OPENTHREADS：BOOL = OFF。

尝试使用这些配置进行配置，但收到以下错误。

我尝试了这些配置，对iPhone模拟器也进行了必要的更改，但是出现了类似的错误。你能告诉我哪里出错了吗？

您应该在cmake中指定IOS SDK版本和iPhone版本。

cmake ../ -G Xcode -DOSG_BUILD_PLATFORM_IPHONE:BOOL=ON \
-DIPHONE_SDKVER="10.3" \
-DIPHONE_VERSION_MIN="8.0" \
-DOPENGL_PROFILE:STRING=GLES2 \
-DBUILD_OSG_APPLICATIONS:BOOL=OFF \
-DBUILD_OSG_EXAMPLES:BOOL=ON \
-DOSG_WINDOWING_SYSTEM:STRING=IOS \
-DOSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX="imageio" \
-DDYNAMIC_OPENSCENEGRAPH:BOOL=OFF \
-DDYNAMIC_OPENTHREADS:BOOL=OFF \
-DCURL_INCLUDE_DIR:PATH="$THIRDPARTY_PATH/curl-ios-device/include" \
-DCURL_LIBRARY:PATH="$THIRDPARTY_PATH/curl-ios-device/lib/libcurl.a"     \
-DFREETYPE_INCLUDE_DIR_freetype2:PATH="$THIRDPARTY_PATH/freetype-ios-          universal/include/freetype" \
-DFREETYPE_INCLUDE_DIR_ft2build:PATH="$THIRDPARTY_PATH/freetype-ios-  universal/include" \
-DFREETYPE_LIBRARY:PATH="$THIRDPARTY_PATH/freetype-ios-universal/lib/libFreeType_iphone_universal.a" \
-DTIFF_INCLUDE_DIR:PATH="$THIRDPARTY_PATH/tiff-ios-device/include" \
-DTIFF_LIBRARY:PATH="$THIRDPARTY_PATH/tiff-ios-device/lib/libtiff.a" \
-DGDAL_INCLUDE_DIR:PATH="$THIRDPARTY_PATH/gdal-ios-device/include" \
-DGDAL_LIBRARY:PATH="$THIRDPARTY_PATH/gdal-ios-device/lib/libgdal.a"

$ THIRDPARTY_PATH是您下载的第三方的目录。
