我正在尝试在我的Mac OSX 10.6上编译“Loch”而没有任何成功。我总是得到一些“编译时未找到的符号”错误。任何人都知道可能是什么问题？

非常感谢

您似乎正在编译64位软件，但编译器找到的库是针对32位软件的。

您需要以32位模式重新编译代码，以便可以使用现有库，或者需要安装（或定位）并指定64位版本库的位置。

对于32位版本，您可以使用：

BITTINESS = -m32
CC = cc ${BITTINESS}
CXX = c++ ${BITTINESS}

如果您以后想要，可以使用“make BITTINESS=-m64”覆盖命令行。

可能还有其他方法可以指定您需要某种通用二进制文件 - 但是如果要为该体系结构构建，您仍需要找到支持x86_64的WX（和QuickTime）库的版本。 / p>

如何识别MacOS X上的文件类型

对于dylib，请使用file：

$ file /usr/lib/libffi.dylib
/usr/lib/libffi.dylib: Mach-O universal binary with 3 architectures
/usr/lib/libffi.dylib (for architecture x86_64):    Mach-O 64-bit dynamically linked shared library x86_64
/usr/lib/libffi.dylib (for architecture i386):  Mach-O dynamically linked shared library i386
/usr/lib/libffi.dylib (for architecture ppc7400):   Mach-O dynamically linked shared library ppc
$

对于存档，提取目标文件：

$ file libjlss-350.a
libjlss-350.a: current ar archive random library
$ ar x libjlss-350.a stuint8.o
$ file stuint8.o
stuint8.o: Mach-O 64-bit object x86_64
$
