PG数据库源码在编译之前，需要首先通过configure脚本，加入一些参数进行配置。例如：想要支持lz4压缩，就需要在configure时，添加参数--with-lz4。
一般情况下，想要把相关功能都配置，详细的configure命令为（本人是Linux系统）：
./configure --enable-debug --with-python --with-perl --with-tcl --with-gssapi --with-pam --with-openssl --with-pam --without-ldap --with-libxml --with-libxslt --without-oci --enable-dtrace --enable-depend --enable-cassert --with-systemd CFLAGS="-O0 -DOPTIMIZER_DEBUG -g3 -gdwarf-2" --prefix=/usr/local/pgsql
在第一次执行的时候，一般会报很多错，主要的原因，还是相关的库，并没有安装。
总结遇到的相关问题如下：
【问题1】：
checking for dtrace... no
configure: error: dtrace not found
解决方法：
yum search dtrace

systemtap-sdt-devel.i686 : Static probe support tools
systemtap-sdt-devel.x86_64 : Static probe support tools
找到了，就安装，我是64位的，安装第二个
yum install -y systemtap-sdt-devel.x86_64
【问题2】：
checking for flags to link embedded Perl... Can't locate ExtUtils/Embed.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .).
BEGIN failed--compilation aborted.
no
configure: error: could not determine flags for linking embedded Perl.
This probably means that ExtUtils::Embed or ExtUtils::MakeMaker is not
installed.
解决方法：
yum install perl-ExtUtils-Embed -y
【问题3】：
configure: error: could not determine flags for linking embedded Perl.
This probably means that ExtUtils::Embed or ExtUtils::MakeMaker is not
installed.
解决方法：
yum install perl-ExtUtils-Embed
【问题4】：
configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable readline support.
解决方法：
yum install readline readline-devel
【问题5】：
checking for inflate in -lz... no
configure: error: zlib library not found
If you have zlib already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper directory.
Use --without-zlib to disable zlib support.
解决方法：
yum install zlib zlib-devel
【问题6】：
checking for CRYPTO_new_ex_data in -lcrypto... no
configure: error: library 'crypto' is required for OpenSSL
解决方法：
yum install openssl openssl-devel
【问题7】：
checking for pam_start in -lpam... no
configure: error: library 'pam' is required for PAM
解决方法：
yum install pam pam-devel
【问题8】：
checking for xmlSaveToBuffer in -lxml2... no
configure: error: library 'xml2' (version >= 2.6.23) is required for XML support
解决方法：
yum install libxml2 libxml2-devel
【问题9】：
checking for xsltCleanupGlobals in -lxslt... no
configure: error: library 'xslt' is required for XSLT support
解决方法：
yum install libxslt libxslt-devel
【问题10】：
configure: error: Tcl shell not found
解决方法：
yum install tcl tcl-devel
【问题11】：

configure: error: header file is required for LDAP
解决方法：
yum install openldap openldap-devel
【问题12】：
checking for Python.h... no
configure: error: header file <Python.h> is required for Python
解决方法：
yum install python python-devel （注意有的机器上需要指定python版本，例如python2-devel或python3.6-devel）
【问题13】：
