添加shared表示编译成动态库
./config no-asm shared no-async --prefix=安装路径 --cross-compile-prefix=编译链
如:
./config no-asm shared no-async --prefix=/opt/work/Release/arm/ec20/openssl/openssl-1.1.1f --cross-compile-prefix=/opt/CrossComplie/ql-ol-sdk/ql-ol-crosstool/sysroots/x86_64-oesdk-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-
注:如果arm是32位系统, 先删除makefile中的 -m64 编译选项
如果是直接安装到本地
./config no-asm shared --prefix=/home/openssl
make
make install
http://mosquitto.org/files/source/
wget http://mosquitto.org/files/source/mosquitto-1.6.10.tar.gz
修改prefix?=的指向, 如:
prefix?=/home/mosquitto/1.6.10
在文档最后添加
CROSS_COMPILE=编译链路径
CC=gcc
CXX=g++
make
make install
http://digip.org/jansson/releases/
configure中修改和添加
cross_compiling=yes
CC=/opt/CrossComplie/ql-ol-sdk/ql-ol-crosstool/sysroots/x86_64-oesdk-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-gcc

如果使用下载https连接, 需要添加ssl选项, 这里使用的是openssl。
编译选项:
–with-libssl-prefix=openssl路径
–with-openssl=openssl路径
–with-ssl=openssl
./configure --host=arm-oe-linux-gnueabi --without-zlib --with-ssl=openssl --with-libssl-prefix=/opt/work/Release/arm/ec20/openssl/openssl-1.1.1h --with-openssl=/opt/work/Release/arm/ec20/openssl/openssl-1.1.1h CC=/opt/CrossComplie/ql-ol-sdk/ql-ol-crosstool/sysroots/x86_64-oesdk-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-gcc --prefix=/opt/work/Release/arm/ec20/wget/wget-1.19.1_openssl-1.1.1h

$ ./configure --help
`configure' configures this package to adapt to many kinds of systems.
Usage: ./configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print `checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for `--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or `..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]
System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-static Build static binaries
--disable-harden Don't set hardened build flags
--disable-largefile omit support for large files
--disable-zlib Don't include zlib support
--enable-pam Try to include PAM support
--disable-openpty Don't use openpty, use alternative method
--disable-syslog Don't include syslog support
--disable-shadow Don't use shadow passwords (if available)
--enable-plugin Enable support for External Public Key Authentication plug-in
--enable-fuzz Build fuzzing. Not recommended for deployment.
--enable-bundled-libtom Force using bundled libtomcrypt/libtommath even if a system version exists.
--disable-bundled-libtom Force using system libtomcrypt/libtommath, fail if it does not exist.
Default is to use system if available, otherwise bundled.
Dropbear requires system libtommath >= 1.2.0 and libtomcrypt >= 1.18.0
--disable-lastlog Disable use of lastlog even if detected no
--disable-utmp Disable use of utmp even if detected no
--disable-utmpx Disable use of utmpx even if detected no
--disable-wtmp Disable use of wtmp even if detected no
--disable-wtmpx Disable use of wtmpx even if detected no
--disable-loginfunc Disable use of login() etc. no
--disable-pututline Disable use of pututline() etc. (uwtmp) no
--disable-pututxline Disable use of pututxline() etc. (uwtmpx) no
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-zlib=PATH Use zlib in PATH
--with-pam=PATH Use pam in PATH
--with-lastlog=FILE|DIR specify lastlog location common locations
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
CXX C++ compiler command
CXXFLAGS C++ compiler flags
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
Report bugs to the package provider.
# 配置
# configure --prefix=安装路径 --host=arm CC=交叉编译链gcc名称
# 安装路径最后使用绝对路径
$ ./configure --prefix=/opt/dropbear/install --host=arm CC=arm-linux-gcc
# 编译
$ make
$ make install
将/opt/dropbear/install目录下的文件复制到嵌入式系统的/usr/bin,/usr/sbin下面
/opt/dropbear/install => /usr/bin,/usr/sbin
注意,在/etc/目录下创建dropbear目录,这一个目录一定要创建,不然client连接不上ssh
mkdir -p /etc/dropbear
/usr/sbin/dropbear -R
启动之后使用putty进行连接测试,可以正常访问,但是不能上下载文件。这是因为没有编译scp, 同时还需要zlib的支持,更详细的编译参考:嵌入式linux轻量级sshd服务工具Dropbear移植
