这是一次失败的任务，即使再来一次，依然会失败，因为无法验证，真够shit的，扣了我10$的手续费。
记录一下，以儆效尤。
任务如下：
Job would be to compile an ipk file of SHC that would work with LEDE OS (openwrt) and the processor used in our system - will provide details SHC can be downloaded here: http://www.datsi.fi.upm.es/~frosal/ I think you must have a 64 bit system to use the SDK to compile the file 翻译一下：在OpenWRT平台下编译一个SHC，并且能工作。
完全步骤如下：
How to compile SHC on LEDE: Tested build environment: OS: Ubuntu 14.04.5 LTS CPU: ARMv7 Processor rev 5 (v7l) Before you begin, check your system is updated, i.e. sudo apt-get update sudo apt-get upgrade sudo apt-get autoremove Step-by-step manual: Note: perform all steps as regular (non-root) user. User must be in sudo group. 1. Update your sources sudo apt-get update 2. Install nesessary packages: sudo apt-get install g++ libncurses5-dev zlib1g-dev bison flex unzip autoconf gawk make gettext gcc binutils patch bzip2 libz-dev asciidoc subversion sphinxsearch libtool sphinx-common libssl-dev libssl0.9.8 3. Get latest LEDE source from git repository We know our CPU is armv7, it belongs to arm64, so go to http://downloads.lede-project.org/releases , just download sdk. wget http://downloads.lede-project.org/releases/17.01.4/targets/arm64/generic/lede-sdk-17.01.4-arm64_gcc-5.4.0_musl-1.1.16.Linux-x86_64.tar.xz 4. No Need to Update and install all LEDE packages We just want to compile shc, not other packages , so don't update. 5. Run 'make menuconfig' (Just Save and Exit) 6. Get SHC sources to LEDE package tree (we are and shc-3.8.9b.tgz is in source directory) wget http://www.datsi.fi.upm.es/~frosal/sources/shc-3.8.9b.tgz mkdir -p package/shc/src tar xvf shc-3.8.9b.tgz -C package/shc/src --strip-components 1 7. Make ipk Makefile vi package/shc/Makefile ############################################## # OpenWrt Makefile for shc program # # # Most of the variables used here are defined in # the include directives below. We just need to # specify a basic description of the package, # where to build our program, where to find # the source files, and where to install the # compiled program on the router. # # Be very careful of spacing in this file. # Indents should be tabs, not spaces, and # there should be no trailing whitespace in # lines that are not commented. # ############################################## include $(TOPDIR)/rules.mk # Name and release number of this package PKG_NAME:=shc PKG_VERSION:=3.8.9b PKG_MAINTAINER:=Francisco, Rosales, <frosal@fi.upm.es> # This specifies the directory where we're going to build the program. # The root build directory, $(BUILD_DIR), is by default the build_mipsel # directory in your OpenWrt SDK directory PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME) include $(INCLUDE_DIR)/package.mk # Specify package information for this program. # The variables defined here should be self explanatory. # If you are running Kamikaze, delete the DESCRIPTION # variable below and uncomment the Kamikaze define # directive for the description below define Package/$(PKG_NAME) SECTION:=utils CATEGORY:=Utilities TITLE:= shc ---- This tool generates a stripped binary executable version of the script specified at command line. URL:=http://www.datsi.fi.upm.es/~frosal endef # Uncomment portion below for Kamikaze and delete DESCRIPTION variable above define Package/$(PKG_NAME)/description shc ---- This tool generates a stripped binary executable version of the script specified at command line." endef # Specify what needs to be done to prepare for building the package. # In our case, we need to copy the source files to the build directory. # This is NOT the default. The default uses the PKG_SOURCE_URL and the # PKG_SOURCE which is not defined here to download the source from the web. # In order to just build a simple program that we have just written, it is # much easier to do it this way. define Build/Prepare mkdir -p $(PKG_BUILD_DIR) $(CP) ./src/* $(PKG_BUILD_DIR)/ endef # We do not need to define Build/Configure or Build/Compile directives # The defaults are appropriate for compiling a simple program such as this one # Specify where and how to install the program. Since we only have one file, # the helloworld executable, install it by copying it to the /bin directory on # the router. The $(1) variable represents the root directory on the router running # OpenWrt. The $(INSTALL_DIR) variable contains a command to prepare the install # directory if it does not already exist. Likewise $(INSTALL_BIN) contains the # command to copy the binary file from its current location (in our case the build # directory) to the install directory. define Package/$(PKG_NAME)/install $(INSTALL_DIR) $(1)/bin $(INSTALL_BIN) $(PKG_BUILD_DIR)/shc $(1)/bin/ endef # This line executes the necessary commands to compile our program. # The above define directives specify all the information needed, but this # line calls BuildPackage which in turn actually uses this information to # build a package. $(eval $(call BuildPackage,$(PKG_NAME))) 8. Compile shc ipk without errors. make package/shc/compile V=99 9. Building process complete witout errors. Now we have : binary packages directory: source/bin/packages/aarch64_armv8-a/ [SHC_BIN] = ./bin/packages/aarch64_armv8-a/base/shc_3.8.9b_aarch64_armv8-a.ipk 10. Copy and install SHC .ipk to LEDE device. scp shc_3.8.9b_aarch64_armv8-a.ipk root@<LEDE device IP address or name>:/tmp/ ssh root@<LEDE device IP address or name> #IP usually 192.168.1.1 opkg install shc_3.8.9b_aarch64_armv8-a.ipk 11. Create test script and compile it to execute. (in LEDE shell) ssh root@<LEDE device IP address or name> #IP usually 192.168.1.1 vi /tmp/1.sh #!/bin/sh echo "hahahaha" shc -v -f /tmp/1.sh /tmp/1.sh.x 这里面有几个注意点，一个是网上有很多教程，上去就是
