This article introduces the knowledge of "how to create an openwrt software package". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Method 1. Generate SDK

Make menuconfig select "Build the OpenWRT SDK", then Save, exit. Make again.

After make is completed, a zip file of SDK is generated in the bin/ramips/ directory:

OpenWrt-SDK-ramips-rt305x_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64.tar.bz2

2. Install SDK

Extract the OpenWrt-SDK-ramips-rt305x_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64.tar.bz2 generated above to another directory

3. Create a helloworld project

In fact, this can be any program, library, etc. that we want to join. Take helloword as an example.

Create a helloword project under any path. For example, it is still in the ~ / Workspace/OpeWRT directory.

$cd ~ / Workspace/OpenWRT$ mkdir helloword$ cd helloword$ touch helloword.c Makefile

The helloword directory is created under the ~ / Workspace/OpenWRT/ directory, and the helloword.c and Makefile files are generated.

The following is the content of helloworld.c:

# include int main () {printf ("This is my hello word!\ n"); return 0;}

The content of Makefile:

Helloworld: helloworld.o $(CC) $(LDFLAGS) helloworld.o-o helloworldhelloworld.o: helloworld.c $(CC) $(CFLAGS)-c helloworld.cclean: rm * .o helloworld

Make yourself to make sure there is no problem with the program, and be sure to pay attention to the tab space.

4. Create a helloworld package

Go to OpenWrt/Packages/ and create a helloworld directory under that directory, and enter that directory.

$cd ~ / Workspace/OpenWrt/OpenWrt-SDK/package$ mkdir helloworld$ cd helloworld

Copy the program we wrote in step 3 to this directory and rename it src. Create a new Makefile file.

$cp-r.. / helloworld src$ touch Makefile

Throughout the process, the package directory structure is as follows:

Package |-- helloworld | |-- Makefile | `--src | |-- helloworld.c |`-- Makefile`-- Makefile

The Makefile file is as follows:

Include $(TOPDIR) / rules.mkPKG_NAME:=helloworldPKG_RELEASE:=1PKG_BUILD_DIR:=$ (BUILD_DIR) / $(PKG_NAME) include $(INCLUDE_DIR) / package.mkdefine Package/helloworld SECTION:=utils CATEGORY:=Utilities TITLE:=Hello worldviews! DEPENDS:=+libwebsockets + libsqlite3 + libjson-cendefdefine Package/helloworld/description It's my first package demo.endefdefine Build/Prepare mkdir-p $(PKG_BUILD_DIR) $(CP). / src/* $(PKG_BUILD_DIR) / endefdefine Package/helloworld/install $(INSTALL_DIR) $(1) / usr/sbin $(INSTALL_BIN) $(PKG_BUILD_DIR) / $(PKG_NAME) $(1) / usr/sbinendef$ (eval $(call BuildPackage,helloworld))

Make-j1 VIPs succeeded. A helloworld_1_ramips_24kec.ipk was generated.

5. Test helloworld

Through WinSCP, you can access / tmp in the openwrt root directory on ipk.

Cd / tmpopkg install helloworld_1_ramips_24kec.ipk

Use the which command to view the path to the helloworld installation:

Which helloworld

Under / bin/ path

Cd / binhelloworld method II. Create a helloworld project

Copy the method 1 create helloworld folder to package under the openwrt root directory.

2. Select helloworld project make menuconfig

Utilities-- "helloworld check and save exit

Make-j3 VIPs

To compile the module separately:

Make package/helloworld/compilemake package/helloworld/install3, experimental helloworldcd / binhelloworld4, follow-up development

Replace the old helloworld file with the new hellworld file

Recompile

Make package/helloworld/compile

Find the regenerated helloworld file under. / build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/helloworld/ipkg-ramips_24kec/helloworld/bin in the openwrt directory and replace the helloworld under router / bin.
