我已经下载了 GNSDK ver.3.2.0.422。

我试图构建一些示例应用程序。但是我遇到了类似以下的错误...

我检查了 makefile 并发现 platform_vars_macos.mk 可能不正确。他们是...

# check cross-compiling setting
ifeq ($(ARCH),)
    IMPLDIR = mac
    IMPLARCH = x86-64
    ARCHFLAGS = -arch i386 -m64 $(MIN_VERSION_OSX_FLAG)

else ifneq ($(filter x86_64 x86-64 x64,$(ARCH)),)
    IMPLDIR = mac
    IMPLARCH = x86-64
    ARCHFLAGS = -arch i386 -m64 $(MIN_VERSION_OSX_FLAG)

我觉得他们应该...

# check cross-compiling setting
ifeq ($(ARCH),)
    IMPLDIR = mac
    IMPLARCH = x86-64
    ARCHFLAGS = -arch x86_64 -m64 $(MIN_VERSION_OSX_FLAG)

else ifneq ($(filter x86_64 x86-64 x64,$(ARCH)),)
    IMPLDIR = mac
    IMPLARCH = x86-64
    ARCHFLAGS = -arch x86_64 -m64 $(MIN_VERSION_OSX_FLAG)

如果我的想法是正确的，请在下一个版本中修复它们。
