当尝试使用来自ports树的g ++(例如++)在OpenBSD上编译ansvif(一个fuzzer)时,一切都配置好并编译好,直到我在需要线程的地方实际运行程序。
我尝试像这样编译:
AUTOCONF_VERSION=2.69 AUTOMAKE_VERSION=1.15 aclocal
AUTOCONF_VERSION=2.69 AUTOMAKE_VERSION=1.15 autoconf
AUTOCONF_VERSION=2.69 AUTOMAKE_VERSION=1.15 automake -a
CXX=/usr/ports/pobj/gcc-4.9.3/bin/eg++ ./configure
make
然后我得到:
terminate called after throwing an instance of 'std::system_error'
what(): Enable multithreading to use std::thread: Operation not permitted
Abort trap (core dumped)
这似乎只能在 OpenBSD 6.0 上使用g ++ 4.9.3从 ports 重现。您无法使用内置的g ++编译代码,因为代码需要C ++ 11。
回溯看起来像这样:

在Linux和Windows下使用相同的编译和工作(使用MinGW)。
我已经阅读了一些类似的问题,说它是一个编译器错误,但是他们在SO上为它提供的hacky'修复'似乎没有帮助(在这种情况下使用-Wl,--no-as-needed
)。
答案 0 :(得分:1)
您将代码与MediaType.APPLICAITON_XML
相关联。您应该使用libstdc++
代替。
