How to get the full path and directory of a Makefile itself like finding Bash script’s own path?
This 2 lines in Makefile get the full path and dir of the Makefile itself:
mkfile_path := $(abspath $(lastword $(MAKEFILE_LIST)))
mkfile_dir := $(dir $(mkfile_path))
The piece of code gets you Makefile, finds its absolute path and the directory. It does not rely on your work directory at all.
The metadata checkpointing in HDFS is done by the Secondary NameNode to merge the fsimage and the edits log files periodically and keep edits log size within a limit. For various reasons, the checkpointing by the Secondary NameNode may fail. For one example, HDFS SecondaraNameNode log shows errors in its log as follows. 2017-08-06 10:54:14,488…
How to find which package provides a file in Debian based releases, such as Linux Mint, Ubuntu? You can use `dpkg`: $ dpkg -S /path/to/the/file -S or –search is the option to make dpkg do a “search”: -S, –search filename-search-pattern… Search for a filename from installed packages. To search which package provides a command file…

tmpfs has blazing speed. Why not set up a high speed NFS server on top of tmpfs? A little trick is required for setting NFS server on top of /dev/shm. If we add a normal entry in /etc/export and them run # exportfs -a exportfs will give us a warning like this: exportfs: Warning: /dev/shm…
Common DNS queries like ping will first get the IP of a hostname if it exists in /etc/hosts. How to find the hostname of an IP using /etc/hosts if it has the mapping on Linux? Multiple tools on Linux can do the “reverse” checking using /etc/hosts file. For example, if we have a line 192.0.2.1…
VC6默认编译出来的程序在XP下Luma风格下运行也是Windows的经典界面, 有损界面的美观与统一. VC2008默认设置下如果不是使用的unicode也是如此. 本文给出使VC6和VC2008可以编译出使用系统界面风格的解决方案. 1. 使VC6编译出使用系统风格的程序 步骤如下: 1) 创建一个.manifest文件的资源. 在res/文件夹下创建一个跟以程序名加.manifest的文件, 如果程序为test.exe, 则创建test.exe.manifest 文件可由此下载: https://www.systutorials.com/t/g/programming/resultcollector.manifest/ 注意要使用utf-8编码保存。 2) 将新定义的资源加入到.rc2文件中, 类型设为24. 打开res/文件夹下的.rc2文件, 在其中加入如下定义: 1 24 MOVEABLE PURE “res/test.exe.manifest” 其中的文件地址按1)步中修改的设置即可. 之后编译即可, 为了使程序界面可能充分利用系统的界面特性, 可以将界面字体设置为TrueType类型的, 利用Windows XP等系统的屏幕字体平滑特性. 2. 使VC2008编译出使用系统风格的程序 在VC2008下就比较简单了, 如果程序字符集使用unicode则默认就是使用系统界面风格的, 如果选择其它的类型, 则编辑下stdafx.h即可. 最后面部分找到这么一段: #ifdef _UNICODE #if defined _M_IX86 #pragma comment(linker,”/manifestdependency:”type=’win32′ name=’Microsoft.Windows.Common-Controls’ version=’6.0.0.0′ processorArchitecture=’x86′ publicKeyToken=’6595b64144ccf1df’ language=’*'””) #elif defined _M_IA64 #pragma comment(linker,”/manifestdependency:”type=’win32’…
Hi! Thanks for the tip.
Maybe you want fix it:
mkfile_dir := $(dir $(mkfile_path))
Fixed. Thanks for the comment.
how to get the files list included by a Makefile?
For example:
TOP?=/vobs
include $(TOP)/util/mak/compiler.mk
and compiler.mk may also include other files.
How to get the all included file list?
thanks
make files paths : /home/ovsa/krupa/Makefile2/tool
/home/ovsa/krupa/Makefile2/runtime
/home/ovsa/krupa/Makefile2/License
iam running the make in :: make -C ./krupa/Makefile2/License all
Giving below error:

make: *** [Makefile:100: create_dirs] Error 1
make: Leaving directory ‘/home/ovsa/krupakar/Makefile2/License’
It is not taking the exact path of the makefile, It is creating the directory in /home
