OS是ORACLE LINUX 9，下载源码并解压，先运行./configure, 提示如下：

configure: error: ICU library not found
If you have ICU already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper directory.
Use --without-icu to disable ICU support.

感觉可以继续吧。于是运行make, 报错如下：

[root@localhost postgresql-16.2]# make
You need to run the 'configure' program first. See the file
'INSTALL' for installation instructions, or visit:
<https://www.postgresql.org/docs/devel/installation.html>
make: *** [Makefile:19: all] Error 1

打开Makefile看，头几句如下：

  @if [ ! -f GNUmakefile ] ; then \
if [ -f INSTALL ] ; then \
INSTRUCTIONS="INSTALL"; \
else \
INSTRUCTIONS="README.git"; \
fi; \
echo "You need to run the 'configure' program first. See the file"; \
echo "'$$INSTRUCTIONS' for installation instructions, or visit: " ; \
echo "<https://www.postgresql.org/docs/devel/installation.html>" ; \
false ; \

似乎再判断时，走到了echo "You need to run the 'configure' program first. See the file"; \  判断的意思时是否有Makefile吧？不是有吗，怎会走到这一步？求PG高手解答
