Question

我正在尝试创建一个具有SSL支持的Android 64位libcurl静态库。

我首先在脚本https://github.com/cocochpie/android-openssl/blob/master/build-all-arch.sh的帮助下编译OpenSSL。我已经对其进行了修改，以便仅针对Android 64位版本构建，并且看到以下输出：

由于/openssl-1.1.0g目录以libssl.a和libcrypto.a结尾，这似乎已成功完成。

然后我下载curl并运行以下配置：

./configure \
       --host=$CHOST \
       --target=aarch64-linux-android \
       --with-ssl=/openssl-1.1.0g \
       --with-zlib \
       --enable-ftp \
       --enable-http \
       --enable-ipv6 \
       --enable-static \
       --disable-dict \
       --disable-file \
       --disable-gopher \
       --disable-imap \
       --disable-ldap \
       --disable-ldaps \
       --disable-manual \
       --disable-pop3 \
       --disable-proxy \
       --disable-rtsp \
       --disable-shared \
       --disable-smb \
       --disable-smtp \
       --disable-sspi \

       --disable-tftp \
       --without-gnutls \
       --without-libidn \
       --without-librtmp

此命令的输出为：

  PSL support:      no      (libpsl not found)
  HTTP2 support:    disabled (--with-nghttp2)
  Protocols:        FTP HTTP

如果我正确地解释了这一点，则libcurl配置未找到SSL库并且在没有SSL支持的情况下进行构建。

对吗？如果是这样，我猜想如果a）找不到所需的文件或b）确实找到了所需的文件，但它们针对不同的体系结构进行了编译，则会发生这种情况。

有人可以指出我在哪里出问题了吗？

根据建议，我浏览了config.log文件。这部分看起来可疑：

我设法找到了用于构建所需内容的出色脚本：。

对我来说，这里最大的收获是，如果您看到“ SSL支持：否”，而您希望看到“是”，则这是两件事之一：1）它找不到SSL的路径或2）路径可能存在，但已编译的SSL用于错误的体系结构。

正如Daniel Stenberg所说，config.log是您的朋友。
