configure: WARNING: openssl/tls1.h: check for missing prerequisite headers?
configure: WARNING: openssl/tls1.h: see the Autoconf documentation

configure: error: OpenSSL and associaed developement headers required

Answer 1

正好我也遇到这个问题，其实是缺少依赖文件，如果是ubantu，加上下面三句话：
apt-get -y install build-essential automake autoconf git-core wget libtool
apt-get -y install libncurses5-dev libtiff-dev libjpeg-dev zlib1g-dev libssldev libsqlite3-dev
apt-get -y install libpcre3-dev libspeexdsp-dev libcurl4-openssl-dev libopus-dev
然后重新./configure

Answer 2

vim Makefile 看看里面的内容是否有install 对应的执行语句。
有些软件只需要make即可。

追问

INSTALL = /usr/bin/install -c
install_sh_DATA = $(install_sh) -c -m 644
install_sh_PROGRAM = $(install_sh) -c
install_sh_SCRIPT = $(install_sh) -c
INSTALL_HEADER = $(INSTALL_DATA)
Makefile 文件内容是这样的
