Yes. There are two major reasons at the moment: 0. The gthread and c11 thread use global BSTs to translate thread IDs to HANDLEs upon *_join() or *_detach() calls, which would be problematic if mcfgthread is linked statically, since each dynamic library as well as the executable is going to have separated maps, and calls to such functions have to be done in the same module that has created the thread.
1. It is essential to use the DllMain() function to clean up TLS objects and invoke thread exit callbacks. Without a dynamic library (for example, in the mingw-64 case), a TLS callback is an option but It requires an IMAGE_TLS_DIRECTORY to work. The mingw-w64 CRT places it in one of the startup files (crt?.o). It is also possible to place it in a static library then reference it somewhere in the startup files (if it is not referenced the linker would ignore it or strip it). In both cases the startup code has to be modified which requires extra inter-project work that I am not very willing to bother myself to do. ------------------ Best regards, lh_mouse 2016-06-29 ------------------------------------------------------------- 发件人：Norbert Pfeiler <norbert.pfeiler+mingw-...@gmail.com> 发送日期：2016-06-29 04:53 收件人：mingw-w64-public 抄送： 主题：Re: [Mingw-w64-public] Proposal for a C11 header and announcement of mcfgthread, a library that implements efficient C11 and C++11 thread support without using winpthread Hi, sorry for being so late. I welcome a proper native thread implementation for windows gcc. I have one point to address: I like the fact that i can easily build static executables with mingw-w64. In a few statements it was suggested that this will not be possible for mcfgthread but i didn’t come across an explanation why. Could you elaborate on that? ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
