arm-linux-androideabi/bin/ld:致命错误:-soname:必须采用非空参数

Question

我正在用cmake android交叉编译gdcm它直到编译结束但最后我得到以下错误.你们如何在编译库时在cmake-gui或cmake中设置-soname,以便我们可以避免出现以下错误.

Answer 1

正如Romanski所指出的,CMake版本3.2和3.0因UseSWIG.cmake文件不同而有不同的行为.在3.2 默认情况下启用的NO_SONAME属性看起来像是在android构建中引发冲突,产生无效的链接选项与空TARGET_SONAME.-Wl,-soname,

使用3.2版本修复构建有两种方法

1. string(REPLACE "<CMAKE_SHARED_LIBRARY_SONAME_CXX_FLAG><TARGET_SONAME>" "" CMAKE_CXX_CREATE_SHARED_MODULE "${CMAKE_CXX_CREATE_SHARED_MODULE}") 完全消除了断开的链接选项
2. set_target_properties(${MY_TARGET} PROPERTIES NO_SONAME OFF) 使用正确的so-name修复损坏的链接选项.
