问题
I am trying to get some older third-party software to compile on OS X 10.9. I've managed to get rid of most compilation problems by adjusting settings in the Makefiles, which were originally written for gcc probably around 2005. However, I currently don't know how to overcome this error for a C++ source file:
/utility.h:42:10: fatal error: 'ext/slist' file not found
I understand that ext/slist belongs to some version of STL. Has that version been superseded or does it have to be activated in any special way for Apple's version of Clang/LLVM (5.0 for OS X 10.9)?
If at all possible, I would prefer to compile this software with the pre-installed tools and not go through such steps as installing gcc via MacPorts.
BTW, these warnings also persist:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/ext/hash_set:202:2: warning: Use of the header is deprecated. Migrate to [-W#warnings] /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/ext/hash_map:209:2: warning: Use of the header is deprecated. Migrate to [-W#warnings]
回答1:
Slist is a singly linked list and was an extention included in libstdc++. Mac OS X has been moving away from libstdc++ toward libc++, which provides a C++11 standard library. C++11 provides a singly linked list under the name std::forward_list in the header <forward_list>.
I believe libstdc++ is still included in the developer tools, so you may also be able to switch your project back to that. If you're using an Xcode project you can select the library in the build settings, or ensure that the program is getting built with -stdlib=libstdc++
