How to solve the problem of compiling OpenWRT process, I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

My operating system is CentOS 6.4.I haven't changed it for a long time. I also started to download and compile OpenWRT according to the instructions of the awesome people on the Internet.

The following is the information on the Internet:

Sudo apt-get update (update)

Install the components required for compilation:

Sudo apt-get install gcc

Sudo apt-get install gathers +

Sudo apt-get install binutils

Sudo apt-get install patch

Sudo apt-get install bzip2

Sudo apt-get install flex

Sudo apt-get install bison

Sudo apt-get install make

Sudo apt-get install autoconf

Sudo apt-get install gettext

Sudo apt-get install texinfo

Sudo apt-get install unzip

Sudo apt-get install sharutils

Sudo apt-get install subversion

Sudo apt-get install libncurses5-dev

Sudo apt-get install ncurses-term

Sudo apt-get install zlib1g-dev

Sudo apt-get install gawk

Sudo apt-get install asciidoc

Sudo apt-get install libz-dev

The compilation environment is completed.

Mkdir openwrt creates an openwrt folder

Cd openwrt enters the openwrt folder

Svn co svn://svn.openwrt.org/openwrt/branches/backfire downloads the source code of the official website

. / scripts/feeds update-a update package

. / scripts/feeds install-an installation package

Make menuconfig enters the customized interface (in which you can select the chip model, integrated components, etc., according to the actual situation)

Defconfig

Make version 99 (start compilation)

All that's left is to wait. the first compilation takes a relatively long time, which has something to do with your computer configuration and Internet speed.

Since the original author uses Ubuntu as the development environment, apt-get is used to install the above dependency toolkits and yum is used in CentOS. In fact, it's all the same, as long as you know which packages to rely on.

The path to the OpenWRT source database of my checkout is: svn://svn.openwrt.org/openwrt/trunk

Follow the above steps for everything else.

Here are some of the problems I have encountered:

. / scripts/feeds update-a failed

Newspaper:

$. / scripts/feeds update-aUpdating feed 'packages' from' https://github.com/openwrt/packages.git'... Cloning into'. / feeds/packages'...fatal: Unable to find remote helper for 'https'failed.

It may be that the path to the git warehouse is incorrect. Just replace https with git.

Search with grep command

$grep 'https://github.com' feeds/*-Rfeeds/packages.tmp/location: https://github.com/openwrt/packages.git

Then change this place.

Try again. The result is still the same, I thought for a moment, this feeds/packages.tmp/location is probably a temporary text. It won't work to change it.

I think I found it in the feeds.conf.default file, too.

$grep 'https://github.com' feeds.conf.default-Rsrc-git packages https://github.com/openwrt/packages.gitsrc-git luci https://github.com/openwrt/luci.gitsrc-git routing https://github.com/openwrt-routing/packages.gitsrc-git telephony https://github.com/openwrt/telephony.gitsrc-git management https://github.com/openwrt-management/packages.gitsrc-git targets https://github.com/openwrt/targets.git

Replace all https in it with git.

Try again, OK.

Postscript: in fact, there is a more fundamental solution, as detailed in the later blog post "git error: Unable to find remote helper for 'https'"

Gconvert.c libiconv

When I first compiled OpenWRT, I got the following error:

Gconvert.c:66:2: error: # error GNU libiconv not in use but included iconv.h is from libiconv

I look for a solution on the Internet, and the result is to say, re-configure:

. / configure-enable-iconv=no-with-libiconv=gnumake

But the crux of the problem is: there is no configure under the trunk path of OpenWRT.

Later, after careful deliberation, it was found that I failed in compiling glib.

$find-name "gconvert.c". / build_dir/host/pkg-config-0.28/glib/glib/gconvert.c

Then I will go directly to the. / build_dir/host/pkg-config-0.28/glib/ path and find that there is a configure file under that path.

Then I say compile glib directly under that path.

$cd build_dir/host/pkg-config-0.28/glib/./configure-enable-iconv=no-with-libiconv=gnumake

In this way, glib successfully passed the compilation.

Go back to the trunk path of OpenWRT and continue make.

As you can see from the second line, the git clone project is used:

Git clone http://git.openwrt.org/project/libubox.git

The whole third line is to package the source code from clone into the tar.gz package.

So I visited: sure enough, http://git.openwrt.org/project/libubox appeared on the 404 page. Don't you think so?

I visited again: http://git.openwrt.org/ results, found this project in the list:

Go to the link project/libubox.git:

I'll git clone it myself.

$cd dl$ mkdir tmp$ cd tmp$ git clone http://git.openwrt.org/project/libubox.git libuboxCloning into 'libubox'...fatal: Unable to find remote helper for' http'

I found a solution to "fatal: Unable to find remote helper for 'http'" on the Internet. Learn that "http:" >

So, I git clone again.

$git clone git://git.openwrt.org/project/libubox.git

As a result, it succeeded in clone.

Then, complete the compilation command process manually:

Mkdir-p / home/hevake_lcj/Workspace/OpenWRT/trunk/tmp/dlcd / home/hevake_lcj/Workspace/OpenWRT/trunk/tmp/dlrm-rf libubox-2015-03-22git clone git://git.openwrt.org/project/libubox.git libubox-2015-03-22 echo "Packing checkout..."

Then, go back to the trunk path of OpenWRT to continue make.

Find package/network/config/netifd/Makefile and open it.

Replace "http:" in line 8 with "git:", then go back to the OpenWRT directory and make.

Note: I will encounter this problem again and again later. It's hot! Replace all one order!

$grep-E "http:.*\ .git" `find-name Makefile | xargs` |\ awk-F:'! / .svn / {print $1}'| uniq | xargs\ sed-I 's/http\ (:. *\ .git\) / git\ 1andg'

In the trunk directory, find the files with "http:xxxxx.git" in Makefile, and replace all "http:xxxxx.git" with "git:xxxxx.git"

$grep-E "https:.*\ .git" `find-name Makefile | xargs` |\ awk-F:'! / .svn / {print $1}'| uniq | xargs\ sed-I 's/https\ (:. *\)\ .git / git\ 1\ .git / g'

Replace https with git

Opkg download failed Checking out files from the git repository...Cloning into 'opkg-9c97d5ecd795709c8584e972bfdf3aee3a5b846d'...fatal: Could not read from remote repository.

Now take a look up to see where make is.

Make [3]: Entering directory `/ home/hevake_lcj/Workspace/OpenWRT/trunk/package/system/opkg'

It turns out that when opkg is in git clone, it may be a problem with the path and failed.

I tried to open Makefile under the opkg path and set the

PKG_SOURCE_URL:= http://git.yoctoproject.org/git/opkg

Change it to:

PKG_SOURCE_URL:=git://git.yoctoproject.org/git/opkg

It still didn't work.

I manually searched opkg and found the official website: http://git.yoctoproject.org/cgit/cgit.cgi/opkg/ opened and saw the following at the bottom of the page:

So I changed the trunk/package/system/opkg/Makefile file and changed the PKG_SOURCE_URL to:

PKG_SOURCE_URL:=git://git.yoctoproject.org/opkg

Go ahead, make, pass!

Linux-firmware clone failed

Fatal: Unable to look up git.kernel.org (port 9418) (Temporary failure in name resolution)

I went to the git.kernel.org website and found linux-firmware 's warehouse https://git.kernel.org/cgit/linux/kernel/git/balbi/linux-firmware.git/.

See the description of the git path at the bottom:

This is not consistent with what is specified in Makefile. So change the git path in Makefile.

Re-make

I've summed up my experience now.

If git clone fails, if it is the problem of http header, replace http with git and try again.

If it still doesn't work, check that the path to git is correct. The simple way is to go to the root node of the git path to find the source code repository and get its real and effective git path.

And change the content in Makefile to OK.

Fatal: reference is not a tree: f404. 22c, which seems to mean that there is no such version of f404. 22c in the git project. Then I have to check to see if this version number is correct.

The linux-firmware downloaded under the trunk/tmp/dl path has not been deleted, so we enter the directory. And check the submission log with git log to get:

The version number of f404336ba808cbd57547196e13367079a23b822c was not found in this file.

Well, I'll change it to the latest version number, b8ac7c7e27dcd13fa3c843aaf62457e9c57ea4db. I hope there's no problem.

At the same time, rename the original download directory under trunk/tmp/dl/ (avoid repeated downloads),

$cd tmp/dl$ mv linux-firmware-f404336ba808cbd57547196e13367079a23b822c/ linux-firmware-b8ac7c7e27dcd13fa3c843aaf62457e9c57ea4db

good! Let's make again.
