I hit this error message while trying to build gnote using GNU Autotools.
I had first run:
$ git clean -xf # to clean the tree of untracked files, then
$ autoreconf # to create the script named `configure`, and finally
$ ./configure # to check my system, and create Makefiles from their templates
Neither po/Makefile.in.in nor po/Makefile.in exist in the source tree that I downloaded.
Yet configure needs to make this po/Makefile, as called for in the root Makefile.am in this line:
SUBDIRS = data src po help
Where do I get, or how do I make, po/Makefile.in.in?
Like all Gnome related packages, gnote uses many steps of buildsystem setup beyond just running autoreconf.
The autogen.sh script gnote comes with should run all the required steps to set up the buildsystem.
As usual, run the autogen.sh script with the --help parameter if you want to call configure separately.
po/Makefile.in.in is created by running intltoolize from the intltool package. It needs to be run from the project tree's root directory.
There isn't much documentation on intltoolize that I could find except for the brief man page, but it's source code says that that it's a fork of an older utility called libtoolize, and it's a relatively short script.
(BTW, if you don't already have intltoolize installed, you can figure out which package installs it, with this: sudo apt-file find intltoolize.)
*.in files are templates used by AutoMake to create a Makefile.
.in.in is a soft link to /usr/share/intltool/Makefile.in.in.

I am following this wiki page to build perf from source as below:
PYTHON=python3 make -C tools/perf install
where ~/bin will be the default build directory.
How can I change the build directory to let's say ~/bin/test? I already have another perf build in ~/bin, and I want to have the new build in a different directory.
I have tried to modify the Makefile (if that is how to do it), but I could not figure it out.
One last silly question: Can I just move my current perf build to another directory or it will screw up its links?
You should be able to easily install into a different directory by specifying prefix=... or DESTDIR=... when running make. You will see this and other info if you run make -C tools/perf help:
$ make -C tools/perf help
...
Perf install targets:
NOTE: documentation build requires asciidoc, xmlto packages to be installed
HINT: use "prefix" or "DESTDIR" to install to a particular
path like "make prefix=/usr/local install install-doc"
install - install compiled binaries
...
Make sure to pass an absolute path to avoid problems (you can use realpath for that):
PYTHON=python3 make -C tools/perf prefix=$(realpath ~/bin/test) install
Some years ago on Ubuntu 16.0.4 I've used this library: git clone https://github.com/Beckhoff/ADS and using only the make command I got build, compile and finally on the main directory I found a file called AdsLib-Linux.a and maybe nothing more than this.
Now I'm on Ubuntu 20.04 I need this library once again but this times make dosn't produce the same output and looking forth to the ReadMe instructions I finally used that instead of make:
meson build
ninja -C build
That now create a new directory build but no .a file as before on the root directory. Instead a new file in the build directory libADSLib.a is there. The same thing happens using right the make command.
Maybe the author changed over the years something on the config files or the behavior of the tools have changed, but I cannot get the former file anymore and I need it for other referencing code that now is not executing anymore.
Looking to the MakeFile I found that in the example folder, differently from the one on the parent directory, the MakeFile has something like that:
$(warning ATTENTION make is deprecated and superseeded by meson)
...
${PROGRAM}: LIB_NAME = ../AdsLib-${OS_NAME}.a
...
But all i've tried reading the guides on meson and ninja about setup, configure, build, and so on, did not produce anymore that file.
I've tried also to first build and then copy all files form the example folder to the parent directory and then build again, but again no .a file there.
How's the right way to configure the build process corectly so that this -Linux.a file is created. Or if not possibile anymore, what does it now produce I can use instead of what produced before?
Meson is a build system generator, similar to CMake or somewhat like ./configure, you need to run meson, then run ninja to actually build something.
You need to run both meson and ninja:
meson setup builddir
ninja -C builddir
Once you do that successfully, there will be a libAdsLib.a inside the builddir directory.
Let me correct a bit #dcbaker, according to their README you should setup build as build directory:
# configure meson to build the library into "build" dir
meson build
# let ninja build the library
ninja -C build
Of course, in general, it shouldn't be specific, but their example code is written in a weird way so this path is hard-coded. So, to use the example:
# configure meson to build example into "build" dir
meson example/build example
# let ninja build the example
ninja -C example/build
# and run the example
./example/build/example
About the library: it's now libAdsLib.a and produced in build directory. The name is set here and it's now in linux naming style, the old one - not. So, you have options:
Update your configuration/build files (Makefile?) where you use it
Copy or make symbolic link, e.g.
$ ln -s <>/build/libAdsLib.a <target_path>/AdsLib-Linux.a
Above it's very dependent on your development environment, do you have installation or setup scripts for it? do you permissions to modify/configure parameters for target application? do you need to support both old and new names? - many questions not related to original question about meson.
I am relatively new to the Cygwin program, and I have a .sh file that I need to edit and execute. I am currently running on Windows 10. I have installed Cygwin64 terminal on my machine.
The full list of steps required are as follows:
Be sure to have libtool installed.
Download protobuf from https://github.com/google/protobuf/ (download ZIP and unZIP at desired location, or clone the repo) The protocol buffer is used for communication between the CuraEngine and the GUI.
Before installing protobuf, change autogen.sh : comment line 18 to line 38 using #s. This removes the dependency on gtest-1.7.0.
Run autogen.sh from the protobuf directory: $ ./autogen.sh
$ ./configure
$ make
$ make install # Requires superused priviliges.
(In case the shared library cannot be loaded, you can try "sudo ldconfig" on Linux systems)
Once I get to 3.:
Before installing protobuf, change autogen.sh : comment line 18 to line 38 using #s. This removes the dependency on gtest-1.7.0.
I am having issues opening up to .sh file in Cygwin to make the appropriate edit.
When I try this command to even execute the .sh file:
$ '/cygdrive/c/Users/Thomas/Desktop/3D Printing/protobuf-master/autogen.sh'
I receive the error:
Could not find source code. Make sure you are running this script
from the root of the distribution tree.
If anyone has some insight as to a solution for this problem it would be greatly appreciated.
You are getting the error from this test in autogen.sh :
# Check that we're being run from the right directory.
if test ! -f src/google/protobuf/stubs/common.h; then
cat >&2 << __EOF__
Could not find source code. Make sure you are running this script from the
root of the distribution tree.
__EOF__
In this test, common.h path is relative to the protbuf install directory, just cd to it before executing the script.
I'm currently learning how to use the autoconf/automake toolchain. I seem to have a general understanding of the workflow here - basically you have a configure.ac script which generates an executable configure file. The generated configure script is then executed by the end user to generate Makefiles, so the program can be built/installed.
So the installation for a typical end-user is basically:
./configure
make
make install
make clean
Okay, now here's where I'm confused:
As a developer, I've noticed that the auto-generated configure script sometimes won't run, and will error with:
config.status: error: cannot find input file: `somedir/Makefile.in'
This confuses me, because I thought the configure script is supposed to generate the Makefile.in. So Googling around for some answers, I've discovered that this can be fixed with an autogen.sh script, which basically "resets" the state of the autoconf environment. A typical autogen.sh script would be something like:
aclocal \
&& automake --add-missing \
&& autoconf
Okay fine. But as an end-user who's downloaded countless tarballs throughout my life, I've never had to use an autogen.sh script. All I did was uncompress the tarball, and do the usual configure/make/make install/make clean routine.
But as a developer who's now using autoconf, it seems that configure doesn't actually run unless you run autogen.sh first. So I find this very confusing, because I thought the end-user shouldn't have to run autogen.sh.
So why do I have to run autogen.sh first - in order for the configure script to find Makefile.in? Why doesn't the configure script simply generate it?
In order to really understand the autotools utilities you have to remember where they come from: they come from an open source world where there are (a) developers who are working from a source code repository (CVS, Git, etc.) and creating a tar file or similar containing source code and putting that tar file up on a download site, and (b) end-users who are getting the source code tar file, compiling that source code on their system and using the resulting binary. Obviously the folks in group (a) also compile the code and use the resulting binary, but the folks in group (b) don't have or need, often, all the tools for development that the folks in group (a) need.
So the use of the tools is geared towards this split, where the people in group (b) don't have access to autoconf, automake, etc.
When using autoconf, people generally check in the configure.ac file (input to autoconf) into source control but do not check in the output of autoconf, the configure script (some projects do check in the configure script of course: it's up to you).
When using automake, people generally check in the Makefile.am file (input to automake) but do not check in the output of automake: Makefile.in.
The configure script basically looks at your system for various optional elements that the package may or may not need, where they can be found, etc. Once it finds this information, it can use it to convert various XXX.in files (typically, but not solely, Makefile.in) into XXX files (for example, Makefile).
So the steps generally go like this: write configure.ac and Makefile.am and check them in. To build the project from source code control checkout, run autoconf to generate configure from configure.ac. Run automake to generate Makefile.in from Makefile.am. Run configure to generate Makefile from Makefile.in. Run make to build the product.
When you want to release the source code (if you're developing an open source product that makes source code releases) you run autoconf and automake, then bundle up the source code with the configure and Makefile.in files, so that people building your source code release just need make and a compiler and don't need any autotools.
Because the order of running autoconf and automake (and libtool if you use it) can be tricky there are scripts like autogen.sh and autoreconf, etc. which are checked into source control to be used by developers building from source control, but these are not needed/used by people building from the source code release tar file etc.
Autoconf and automake are often used together but you can use autoconf without automake, if you want to write your own Makefile.in.
For this error:
config.status: error: cannot find input file: `somedir/Makefile.in'
In the directory where the configure.ac is located in the Makefile.am add a line with the subdirectory somedir
SUBDIRS = somedir
Inside somedir put a Makefile.am with all the description. then run automaker --add-missing
A better description can be found in 7.1 Recursing subdirectories automake manual.

This question has been asked many time but I am not able to resolve the problem from them so I am asking
I had installed Cygwin a few days ago.I tried using ./configure command but it says
-bash: ./configure: No such file or directory
I tried using
where configure
but I got the output
INFO: Could not find files for the given pattern(s).
then I tried grep configureand I got this output
/etc/bash_completion.d/configure
/usr/i686-pc-cygwin/sys-root/usr/share/libtool/libltdl/configure
/usr/share/ELFIO/configure
/usr/share/libtool/libltdl/configure
I tried to export the path and then run the ./configure but it also didn't worked.
I find no executable file named as configure in my cygwin bin directory.
Does it mean that I have to add configure file manually?How can I correct it?
NOTE :- I had also tried sh configure but it also didn't worked
If a software project is set up to be built using autoconf, that tool generates a script canonically called configure. It queries the system for various parameters that are subsequently used in the build, and is specific to the software package to be built. Different software projects have different configure scripts. They are all called configure, but their contents are not the same.
So, to actually build such a software project once that script was set up (usually done by the maintainers when packaging the source tarball for distribution), you call:
tar xzf <tarball>.gz # or xjf <tarball>.bz2 or whatever
cd <sourcedir> # the one you just untarred
./configure
make
make install
Note the prefix ./, which means "located in this directory" (i.e. the top directory of that project's source tree).
Actually, the better procedure is the so-called "out-of-tree build", when you set up a different directory for the binaries to be built in, so the source tree remains unmodified:
tar xzf <tarball>.gz # or xjf <tarball>.bz2 or whatever
mkdir builddir
cd builddir
../<sourcedir>/configure
make
make install
So, there is supposed to be no configure executable in your PATH, you are supposed to call the script of that name from the source tree you are trying to build from.
If I correctly understood...
Configure is not an application that should be installed on your system, but script that should be delivered with source code to prepare for make command. File named configure should be in the main directory of source code.
I understand that this is an old question. However many might find this solution helpful.
Normally we use the make command to compile a downloaded source in cygwin. In many cases it contains a autogen.sh file. Running that file with
bash autogen.sh
will in many case solve the problem. At least it solved my issue and i could then use the make command
