如何编译GnuTLS

Question

我试图在Centos 6.2上多次编译GnuTLS库,但没有运气.这些是步骤:

我下载了Nettle 2.4

[root@localhost opt]# wget http://www.lysator.liu.se/~nisse/archive/nettle-2.4.tar.gz
[root@localhost nettle-2.4]# tar zxvf nettle-2.4.tar.gz
[root@localhost nettle-2.4]# cd nettle-2.4
[root@localhost nettle-2.4]# ./configure --enable-shared --prefix=/usr



  Version:           nettle 2.4
  Host type:         x86_64-unknown-linux-gnu
  ABI:               64
  Assembly files:    x86_64
  Install prefix:    /usr
  Library directory: ${exec_prefix}/lib64
  Compiler:          gcc
  Shared libraries:  yes
  Public key crypto: no

我运行命令make和make install

我下载了最新的GnuTLS

 ./configure --with-libnettle-prefix=/usr

hecking for shared library run path origin... done
checking whether to use nettle... yes
checking for libnettle... no
configure: error:
  ***
  *** Libnettle 2.4 was not found.

我错过了什么？

最好的祝愿

Answer 1

问题是libhogweednettle 不会构建,除非你已经观察到了libgmp的dev头文件.不幸的是,.configure --help来自configure 的文档和输出没有说明这一点.

同时,gnuTLS文档也没有解释这一点(正如你所注意到的,这里的配置输出不是很有帮助).虽然libgmp被列为pre-req,但由于某些原因libhogweed不是(也许是因为它被认为是nettle的一部分).配置错误"无法找到-lgmp"的原因是libgmp不存在,但libhogweed.so也不存在,因为它是nettle 的隐藏可选部分.如果你然后安装libgmp-dev并且只运行configure for gnutls,那么你将获得相同的"检查libnettle ...... no".这应该说的是"检查libhogweed ......不",但负责conf脚本的人太懒了,不能打破它(我猜一个补丁可以提交).

换句话说,在构建gnutls之前,需要先安装libgmp-dev 然后重建 nettle .

configure:8798: checking for libnettle
configure:8820: gcc -std=gnu99 -o conftest -g -O2   conftest.c  /usr/lib/libnettle.so /usr/lib/libhogweed.so -lgmp >&5
/usr/bin/ld: cannot find -lgmp
collect2: ld returned 1 exit status
configure:8820: $? = 1
configure: failed program was:
configure:8830: result: no
configure:8856: error: 
  ***
  *** Libnettle 2.4 was not found.

我安装 gmp-devel。问题已解决。
