内容:
编译环境是MSYS2 64 bits，编译器使用MinGW64 4.9.2-5
Qt5.4.1的配置为：
./configure -top-level -platform win32-g++ -release -static -strip -qt-freetype -openssl-linked -dbus-linked -qt-sql-sqlite -qt-sql-odbc -no-reduce-exports -opensource -confirm-license -c++11 -qt-harfbuzz -largefile -optimized-qmake -accessibility -gui -widgets -icu -opengl desktop -egl -no-eglfs -iconv -qt-zlib -qt-libpng -qt-libjpeg -mtdev -alsa -no-gtkstyle -force-pkg-config -make libs -make tools -nomake examples -no-compile-examples -prefix /D/Qt/Qt5.4.1/5.4/mingw492_64sll -silent在编译到工具xmlpatterns.exe时报告错误：

collect2.exe: error: ld returned 1 exit status看那意思好像是未定义的引用。但我打开MinGW的lib目录下的libcrypto.a查看发现是能找到这些函数符号的。
有高手能帮忙参考一下吗？谢谢了先！

libcrypto.a 是openssl的静态库,这个错误说明libcrypto.a依赖gdi32.
当你的程序连接libcrypto.a的时候,应该还要连接它的依赖库.
你可以修改xmlpatterns目录下的工程文件,为cfalgs加上-lgdi32

谢谢，现在已经通过修改configure脚本使用pkg-config --libs --static openssl解决了
