尝试在 Solaris 10 SPARC 64 上编译 Protobuf-2.6.1 时,我得到:
./google/protobuf/stubs/once.h: In function `void google::protobuf::GoogleOnceInit(google::protobuf::ProtobufOnceType*, void (*)())':
./google/protobuf/stubs/once.h:125: error: cannot convert `google::protobuf::ProtobufOnceType*' to `const volatile google::protobuf::internal::Atomic32*' for argument `1' to `google::protobuf::internal::Atomic32 google::protobuf::internal::Acquire_Load(const volatile google::protobuf::internal::Atomic32*)'
./google/protobuf/stubs/once.h: In function `void google::protobuf::GoogleOnceInit(google::protobuf::ProtobufOnceType*, void (*)(Arg*), Arg*)':
./google/protobuf/stubs/once.h:134: error: cannot convert `google::protobuf::ProtobufOnceType*' to `const volatile google::protobuf::internal::Atomic32*' for argument `1' to `google::protobuf::internal::Atomic32 google::protobuf::internal::Acquire_Load(const volatile google::protobuf::internal::Atomic32*)'
我遵循了官方自述文件,./configure
并且make
.
编译器版本(GCC):
$ gcc -v

gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)
我还阅读了问题protobuf generated files does not compile on Solaris SPARC 64并尝试过,但没有成功。那篇文章适用于 Protobuf-2.4.1,但 Protobuf-2.6.1 发生了变化:
2014-10-20 version 2.6.1:
C++
* Added atomicops support for Solaris.
有什么办法可以让 GCC 强制指针转换?
