回复: LLVM完整版（编译QDoc需要）

fsu0413:我就是想知道这个特殊的方法是啥。。。。
既然没有说明，我如果想编译出和这个一摸一样的就得自己调查。。。。。。。。。 (2020-10-20 20:38)
2楼提到的静态编译的llvm6.0应该是用脚本https://code.qt.io/cgit/qtsdk/qtsdk.git/tree/packaging-tools/build_clang_qdoc.py的某个历史版本编译的（比如https://code.qt.io/cgit/qtsdk/qtsdk.git/tree/packaging-tools/build_clang_qdoc.py?id=e71c621f5a06166bec5eafde3efb89c3ac949ae2）
关键是这几行：
pack_command = ['lib.exe', '/OUT:' + os.path.join(install_path, 'lib', 'libclang_static.lib')]
for file in os.listdir(os.path.join(build_path_static, 'lib')):
if file.endswith('.lib') and file != 'libclang.lib':
pack_command.append(file)
bld_utils.runCommand(pack_command, os.path.join(build_path_static, 'lib'), None, environment)
而build_clang_qdoc.py目前的版本没有了相关操作，静态编译出来的clang 10.0和11.0（应该就是https://download.qt.io/development_releases/prebuilt/libclang/qt/目录下的）也没有libclang_static.lib，但是也可以用于qdoc.exe的编译，只需要参照https://codereview.qt-project.org/c/qt/qttools/+/313377来修改Qt源码下的qttools\src\qdoc\configure.pri，或者等Qt 5.15.2发布
https://code.qt.io/cgit/qtsdk/qtsdk.git/tree/packaging-tools目录下还有很多用于编译、打包的脚本

好 我看看，非常感谢

还要请教大佬们一个问题，我想静态连接openssl，使用参数：configure.bat -debug-and-release -static -opensource -confirm-license -platform win32-msvc -prefix "C:\Qt\6.2.2\msvc2019_x64" -I "E:\Develop\2019\x64\OpenSSL\include" -L "E:\Develop\2019\x64\OpenSSL\lib" -- -D OPENSSL_USE_STATIC_LIBS=ON
一直报：Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY) (found version "1.1.1i")
就算找到了，也是libcrypto64MDd.lib连接的动态lib，我想连接MT的lib，何解？

.......
configure.bat -debug-and-release -static -static-runtime -prefix "C:\Qt\6.2.2\msvc2019_x64" -- -DOPENSSL_ROOT_DIR="E:\Develop\2019\x64\OpenSSL" -DOPENSSL_USE_STATIC_LIBS=ON -DOPENSSL_MSVC_STATIC_RT=ON
Qt 6 不再需要 -opensource -confirm-license
如果要链接MT的lib，Qt 也应该要编译为MT，不要混用MD(d)和MT(d)，所以必须加上 -static-runtime
把CMake变量OPENSSL_ROOT_DIR设置为"E:\Develop\2019\x64\OpenSSL"，应该就能找到openssl，不建议使用 -I 和 -L
把CMake变量OPENSSL_MSVC_STATIC_RT设置为ON或TRUE，就会优先找到MT的lib

感谢大佬指点，我用你发的这个选项找到mt了，但是到这里就挂了
