我有一个应用程序，该应用程序使用libcurl库与NGHTTP2-library结合使用，我想静态链接。
我用来构建的构建命令：
i686-w64-mingw32-g++ -Wall Programm.cpp -o Programm.exe -I/opt/mingw64/Win32/include -L/opt/mingw64/Win32/lib -I/Software -I/Software/Deps -std=c++11 -lgcc -lstdc++ -lnghttp2 -lcurl -lssl -lcrypto -DCURL_STATICLIB -lpthread -lws2_32 -static
它产生的建筑物：

我已使用以下命令构建了NGHTTP2：
wget https://github.com/nghttp2/nghttp2/releases/download/v1.27.0/nghttp2-1.27.0.tar.gz
tar xf nghttp2-1.27.0.tar.gz
cd nghttp2-1.27.0/
./configure --host=i686-w64-mingw32 --prefix=/opt/mingw64/Win32
make
make install
那么，使用nghttp2库来查看静态链接libcurl的构建命令有什么问题？
github上的问题的解决方案：
./buildconf
CPPFLAGS="-DNGHTTP2_STATICLIB" LDFLAGS="-static" PKG_CONFIG="pkg-config --
static" ./configure --enable-static ......
make curl_LDFLAGS=-all-static V=1
make curl_LDFLAGS=-all-static install V=1
谢谢杰伊。
