为什么 websockets.c libonion 的例子给出错误 "Cant calculate SHA1 if gnutls is not compiled in!"
Why websockets.c example of libonion gives error "Cant calculate SHA1 if gnutls is not compiled in!"
我正在尝试 运行 libonion (https://github.com/davidmoreno/onion/tree/master/examples/websockets) 的 websockets.c 示例。但是,当我 运行 它时,它给出了这个错误。
"[错误 codecs.c:389] 如果没有编译 gnutls,则无法计算 SHA1!现在中止"
其他例子运行宁没问题。
我正在编译:
$ gcc -o muz websockets.c -I$ONION_DIR/src/ -L$ONION_DIR/src/onion/ -lonion_static -Lpam -Lgnutls -Lgcrypt -lpthread
终端输出如下。

应该不需要单独编译示例,它应该会随着整个项目自动编译。例如,如果您在主包目录中,请创建一个干净的目录并从中 运行 cmake:
mkdir build && cd build
cmake ..
然后查看 cmake 的输出并确保找到所有第 3 方库和其他依赖项。对于 gnutls,它应该如下所示:
-- Found GnuTLS: /usr/lib/libgnutls.so (found version "3.5.13")
-- Found GCrypt: /usr/include (found version "1.7.7")
-- SSL support is compiled in.
如果您收到如下错误消息:
Gnutls or gcrypt not found. SSL support is not compiled in.
,您必须确保 libgnutls.so 已安装并且可以在默认搜索路径中找到(例如 /usr/lib/
)。
修复 cmake 错误和 运行 make
后,您应该可以在 examples/websockets/websockets
.
