无法 dlopen 加载模块 '/usr/lib/pa20_64/libpthread.1'因为它包含线程特定的数据
我在使用 dlopen() 加载库时遇到此错误：
Cannot dlopen load module '/usr/lib/pa20_64/libpthread.1' because it contains thread specific data.
我在谷歌上查找了这个错误，以下导出修复了它。
export LD_PRELOAD=/usr/lib/hpux64/libpthread.so.1
谁能告诉我 LD_PRELOAD 到底做什么以及为什么我必须预加载这个库？为什么链接器不加载它？
使用 -lpthread 编译也没有帮助。

I get this error while loading a lib with dlopen():
Cannot dlopen load module '/usr/lib/pa20_64/libpthread.1' because it contains thread specific data.
I looked this up on google and the following export fixed it.
export LD_PRELOAD=/usr/lib/hpux64/libpthread.so.1
Can anybody tell me what exactly LD_PRELOAD does and why I have to preload this lib? Why does the linker not load it?
Compiling with -lpthread does not help either.

我无法告诉您有关 HPUX 的所有详细信息，但请尝试使用 -lpthread 链接您的程序 - 这可能会解决您的问题。
事实上，您正在 dlopen() 处理的库似乎在运行时挖掘以查找 libpthread 的版本。 LD_PRELOAD 只是加载指定的库，就像您已经 dlopened 它们一样，但它是在程序有机会开始运行之前执行的。
不确定细节，但有一个模糊的猜测：您正在使用的某些库在 dlopen 触发 libpthread 加载之前调用了 pthread 静态数据函数（但是如果第一个库将其作为依赖项，那么为什么它会尝试加载 pthread ？ - 不确定/也许这表明以前的库静态链接了一些 pthread 内容？）。
I can't tell you all the details on HPUX, but try linking your program with -lpthread - that may solve your problem.
As is, the library you're dlopen()ing seems to be digging around at run-time to find a version of libpthread. LD_PRELOAD just loads the specified library as if you'd dlopened them, but it does it before the program has a chance to start running.
Not sure of details, but a vague guess: some library you're using has called the pthread static data functions before your dlopen triggers a load of libpthread (but why would it try to load pthread then if the first library had it as a dependency? - not sure / maybe that indicates the former library statically linked some pthread content?).
