使用 OpenSSL 编译时的 qtum-core 构建问题

Question

我在尝试构建 qtum-core 时遇到错误。错误是：

这是什么问题，我该如何解决？

我的服务器环境

OS - Linux xxxxxxx-X10SLL-F 4.4.0-31-generic #50~14.04.1-Ubuntu SMP 7 月 13 日星期三 01:07:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux openssl 版本 - OpenSSL 1.0.2g
如何解决这个问题？

Answer 1

  CXX      libbitcoin_common_a-key.o
key.cpp: In function ‘bool EnsureLowS(std::vector<unsigned char>&)’:
key.cpp:149:19: error: invalid use of incomplete type ‘ECDSA_SIG {aka struct ECDSA_SIG_st}’
     if (BN_cmp(sig->s, halforder) > 0) {
                   ^

看起来您的机器本地有 OpenSSL 1.1.0，但是 qtum-core 是为 OpenSSL 1.0.2 编写的。那是因为 incomplete type ECDSA_SIG 错误。 OpenSSL 1.1.0 使 OpenSSL 1.1.0 中的一些东西变得私有，这些东西曾经是 public 并且在 OpenSSL 1.0.2 中可以访问。

你可以做两件事。首先，降级到 OpenSSL 1.0.2，以便 qtum-core 可以再次访问数据成员。

其次，您可以将 qtum-core 升级到支持 OpenSSL 1.1.0 的版本。如果 qtum-core 不支持 OpenSSL 1.1.0，请提交错误报告让作者了解该问题。

您问的问题可能是Qtum Issue 382。如果是这样，那么您唯一的选择似乎是选项 (1)，降级到 OpenSSL 1.0.2。

这里是如何配置不同的 OpenSSL（即，不同于发行版的）。

$ git clone https://github.com/qtumproject/qtum.git
$ cd qtum/
$ autoreconf -f -i
libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, 'build-aux'.
libtoolize: copying file 'build-aux/ltmain.sh'
libtoolize: putting macros in AC_CONFIG_MACRO_DIRS, 'build-aux/m4'.
libtoolize: copying file 'build-aux/m4/libtool.m4'
libtoolize: copying file 'build-aux/m4/ltoptions.m4'
libtoolize: copying file 'build-aux/m4/ltsugar.m4'
libtoolize: copying file 'build-aux/m4/ltversion.m4'
libtoolize: copying file 'build-aux/m4/lt~obsolete.m4'
...

这是重要的部分，在运行ning make 之前：

$ ./configure --help | grep -i -E 'ssl|crypto'
  SSL_CFLAGS  C compiler flags for SSL, overriding pkg-config
  SSL_LIBS    linker flags for SSL, overriding pkg-config
  CRYPTO_CFLAGS
              C compiler flags for CRYPTO, overriding pkg-config
  CRYPTO_LIBS linker flags for CRYPTO, overriding pkg-config

没有 --with-XXX 控制 OpenSSL 的选项，但可以通过 pkg-config 选择。所以...

我在 /usr/local 中安装升级。 Headers 在 /usr/local/include 中，库在 /usr/local/lib64 中（因为它是 Fedora）。 OpenSSL本地版本为1.0.2:

$ cat /usr/local/lib64/pkgconfig/libssl.pc
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib64
includedir=${prefix}/include

Name: OpenSSL-libssl
Description: Secure Sockets Layer and cryptography libraries
Version: 1.0.2n
Requires.private: libcrypto
Libs: -L${libdir} -lssl
Libs.private: -Wl,-R,/usr/local/lib64 -Wl,--enable-new-dtags -ldl
Cflags: -I${includedir}

$ cat /usr/local/lib64/pkgconfig/libcrypto.pc
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib64
includedir=${prefix}/include
enginesdir=${libdir}/engines

Requires:
Libs: -L${libdir} -lcrypto
Libs.private: -Wl,-R,/usr/local/lib64 -Wl,--enable-new-dtags -ldl
Cflags: -I${includedir}

我准备好建造了。下一步是（--disable-wallet 因为我不想修复 Autools 错误）：

$ PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig/ ./configure --disable-wallet
configure: loading site script /usr/local/share/config.site
checking build system type... x86_64-pc-linux-gnu

checking for gawk... gawk
...
checking for dynamic linked boost test... yes
checking for mismatched boost c++11 scoped enums... ok
checking for SSL... yes
checking for CRYPTO... yes
...

相关的，我在Noloader | Build-Scripts有一些安装OpenSSL和一些其他程序的脚本。克隆 repo，然后运行:

./build-cacerts.sh  # install CA's needed for Wget downloads
./build-openssl.sh  # download, build and install OpenSSL in /usr/local

我将构建脚本用于下层客户端，例如 Fedora 7 和 Solaris 10。您不必使用构建脚本。但是您确实需要在本地安装 OpenSSL 1.0.2 的副本。
