我正在与cmake android交叉编译gdcm,它一直到编译结束,但最后我得到了以下错误。在编译库时,你们如何在cmakegui或cmake中设置-soname,这样我们就可以避免下面的错误。

正如Romanski所指出的,CMake版本3.2和3.0由于UseSWIG.cmake
文件的不同而具有不同的行为。在3.2中,默认启用的NO_SONAME
属性看起来会在android构建中引发冲突,从而产生无效的链接选项-Wl,-soname,
和空的TARGET_SONAME。
有两种方法可以修复3.2版本的构建
string(REPLACE "<CMAKE_SHARED_LIBRARY_SONAME_CXX_FLAG><TARGET_SONAME>" "" CMAKE_CXX_CREATE_SHARED_MODULE "${CMAKE_CXX_CREATE_SHARED_MODULE}")
完全消除了断开的链接选项set_target_properties(${MY_TARGET} PROPERTIES NO_SONAME OFF)
用正确的so名称修复断开的链接选项
