Gstreamer编译篇_libmount

/usr/lib/x86_64-linux-gnu/libmount.so: file not recognized: File format not…

在交叉编译的时候出现libmount.so文件格式不正确

因为现在是在交叉编译环境下啊。

仔细对比了glib的meson.build

# libmount is only used by gio, but we need to fetch the libs to generate the
# pkg-config file below
libmount_dep = []
if host_system == 'linux'
  libmount_dep = dependency('mount', version : '>=2.23', required : get_option('libmount'))
  glib_conf.set('HAVE_LIBMOUNT', libmount_dep.found())
endif

与

# libmount is only used by gio, but we need to fetch the libs to generate the
# pkg-config file below
libmount_dep = []
if host_system == 'linux' and get_option('libmount')
  libmount_dep = [dependency('mount', version : '>=2.23', required : true)]
  glib_conf.set('HAVE_LIBMOUNT', 1)
endif

你会发现，还是有些不同的。

第一种写法，其实是直接disable libmount了。第二种是强制要求libmount的。

option('libmount',
       type : 'feature',
       value : 'auto',
       description : 'build with libmount support')## auto，默认就是disable的
 

其实编译glib直接加上**-Dlibmount=false**就行了。
