I want to run 'make install' so I have everything I need, but I'd like it to install the things in their own folder as opposed to the system's /usr/bin etc. is that possible? even if it references tools in the /usr/bin etc.?
It depends on the package. If the Makefile is generated by GNU autotools (./configure) you can usually set the target location like so:
./configure --prefix=/somewhere/else/than/usr/local
If the Makefile is not generated by autotools, but distributed along with the software, simply open it up in an editor and change it. The install target directory is probably defined in a variable somewhere.
Since don't know which version of automake you can use DESTDIR environment variable.
See Makefile to be sure.
For example:
export DESTDIR="$HOME/Software/LocalInstall" && make -j4 install
make DESTDIR=./new/customized/path install
This quick command worked for me for opencv release 3.2.0 installation on Ubuntu 16. DESTDIR path can be relative as well as absolute.
Such redirection can also be useful in case user does not have admin privileges as long as DESTDIR location has right access for the user. e.g /home//
It could be dependent upon what is supported by the module you are trying to compile. If your makefile is generated by using autotools, use:
--prefix=<myinstalldir>
when running the ./configure
some packages allow you to also override when running:
make prefix=<myinstalldir>
however, if your not using ./configure, only way to know for sure is to open up the makefile and check. It should be one of the first few variables at the top.
If the package provides a Makefile.PL - one can use:
perl Makefile.PL PREFIX=/home/my/local/lib LIB=/home/my/local/lib
make
make test
make install
* further explanation: https://www.perlmonks.org/?node_id=564720
I tried the above solutions. None worked.
In the end I opened Makefile file and manually changed prefix path to desired installation path like below.
PREFIX ?= "installation path"
When I tried --prefix, "make" complained that there is not such command input. However, perhaps some packages accepts --prefix which is of course a cleaner solution.
try using INSTALL_ROOT.
make install INSTALL_ROOT=$INSTALL_DIRECTORY

I just installed Cmake from git clone wget http://www.cmake.org/files/v2.8/cmake-2.8.3.tar.gz in a new folder on a Linux server. The compilation worked but cmake command is not recognized from other paths. Should I copy the entire contents of cmake-2.8.0 folder to usr/local/bin? Or is the contents of bin folder that need to be copied?
Thanks
On Linux and other Unix-based systems, a common arrangement is to install packages to /opt and add relevant entries to the PATH environment variable to make them available. This is intended for packages not provided by the native package manager or distribution. By choosing an appropriate directory structure, this can be done in a way which also allows different versions to be installed simultaneously and the user can pick which one they want by adding the relevant directory to the PATH.
For the specific case of CMake asked about in the question, you can use a directory structure like /opt/cmake/<version> and then add the relevant /opt/cmake/<version>/bin directory to your PATH (e.g. /opt/cmake/3.8.2/bin for the 3.8.2 CMake release). You can even just download the official pre-built CMake tarballs, unpack them and move the top level directory into the /opt/cmake area as the particular version you downloaded. I've used this successfully on Linux, MacOS and Solaris, as I'm sure have many others.
Note that once you've run CMake on a particular source tree, the cmake executable doesn't need to be on the PATH any more. If cmake needs to be re-run, the build will do so itself and it records the full path to the cmake executable in its own cache, so the PATH isn't even consulted (this is essential in ensuring the same version of CMake continues to be used for all builds regardless of the PATH, since PATH can change between login sessions, etc.). You would only need cmake on your PATH if you intend to invoke cmake manually or for the first time you run it on a source tree, but in both of these cases you can always just use the full path to the cmake executable if you preferred.
I should also add that the entire set of files provided in the CMake package are required, not just the bin directory. CMake makes extensive use of files in its other directories, such as the various modules it comes with. If you are building CMake from source, you may want to build the package target so you get a relocatable tarball or similar which will contain everything that should be included when you provide a CMake package on your system.
After the build, use 'sudo make install'. This will make sure the correct libraries and binaries are copied to their proper places.
Usually this will install the binary to /usr/local/bin.
Make sure the PATH variable has this included.
sudo make install did not copy to /usr/local/bin/ for some reason, so I copied the content of CMAKE /bin. to usr/local/bin an it worked.
cp –a bin/. /usr/local/bin/
Archlinux.
I downloaded mtools, which includes mcopy, which is what I'm after. The instructions in the INSTALL file say do this:
# ./configure
# make
These worked fine, now I have a bunch of .o files and of course executables.
What do I need to do, so I can just type
# mcopy
and have it run? Since I don't have it "installed" right now, doing that just says
-bash: mcopy: command not found
The usual linux build sequence is
./configure
make
make check
sudo make install
make check attempts to validate if the build took place correctly; not all Makefiles have it but many do. Note you will need sudo make install to do the install in the usual system directories if you are not root.
You can determine which of these options is available for your particular Makefile by
cat Makefile
and reading the labels on the left of the file.
You could create a symbolic link to the application in your /usr/bin folder like
ln -s /fullpath/to/app /usr/bin/aliasnameforapp
Then you can simple call aliasnameforapp from anywhere.
I am writing a shared library for GNU/Linux, which will install for now with "sudo make install". I have CMake recipes to create the files and install them in '/usr/local/lib/app', and the libraries and links are created correctly.
But the library path is not updated and I must run "sudo ldconfig /usr/local/lib/app' manually to make the library available.
Several other packages on my system put their libraries in a specific folder under /usr/local/lib, so I am assuming that's proper.
How then to have CMake update the library path for the system as well as create the files and install them? What is the proper way to do this?
I'd also like it accomplished so that the library path update survives a system restart.
Thanks,

I'd also like it accomplished so that the library path update survives a system restart.
I'm not aware of any CMake-specific facility. However, you should be able to add rules such as the following in order to make the change persistent.
echo "/usr/local/bret/lib" > /etc/ld.so.conf.d/bret-i386.conf
echo "/usr/local/bret/lib64" > /etc/ld.so.conf.d/bret-x86_64.conf
/sbin/ldconfig
You'll still need to re-run the ldconfig when you overwrite files in bret/lib{,64}.
I've stumbled on a make file "Makefile.am" and I tried to use "make -f Makefile.am" on it to no avail. What am I doing wrong?
It's an automake script/makefile. You can learn everything about automake, autoconf, libtool and such through the called autobook.
Basically, the steps would be to run automake, then autoconf, then configure, then make to build the software you have. These steps are neccessary to build the configure script, that automatically search for needed libraries and such on your system.
The process is not easy, unless your software also includes an already generated "configure" file. If so, the only thing you have to do (mostly) is to just run ./configure, then make, then make install to install the software to a default location. If you want to change configure options, you can also look at ./configure --help.
You stumbled upon an automake file, which is used to create a Makefile from the source, in this case Makefile.am.
From http://developer.gnome.org/doc/GGAD/z70.html, they explain it as:
automake processes Makefile.am to produce a standards-compliant Makefile.in. automake does a lot of work for you: it keeps up with dependencies between source files, for example. It creates all the standard targets, such as install and clean. It also creates more complex targets: simply typing make dist creates a standard .tar.gz file if your Makefile.am is correct.
Basically, you should run 'automake' to make the Makefile, and you will probably run into the same situation with the configure script with 'autoconf'.
Automake: http://www.gnu.org/software/automake/
Wikipedia article on automake: http://en.wikipedia.org/wiki/Automake
If you are trying to compile a 3rd party application from source, there is usually a 'configure' script located at the top of the source tree. If you run ./configure --help from that location, you'll get a list of options you can set. Usually, --prefix is the most common to use.
After running the script, you'll get standard Makefile's generated from the automake files. From there, you can just execute make normally.
Standard build steps for linux packages are:
./configure
make
make install
see "man automake" or google for autotools. likely you'll want to run something like autogen.sh first.
I've written a C++ program (command line, portable code) and I'm trying to release a Linux version at the same time as the Windows version. I've written a makefile as follows:
ayane: *.cpp *.h
g++ -Wno-write-strings -oayane *.cpp
Straightforward enough so far; but I'm given to understand it's customary to have a second step, make install. So when I put the install: target in the makefile... what command should be associated with it? (If possible I'd prefer it to work on all Unix systems as well as Linux.)
Installation
A less trivial installer will copy several things into place, first insuring that the appropriate paths exists (using mkdir -p or similar). Typically something like this:
the executable goes in $INSTALL_PATH/bin
any libraries built for external consumption go in $INSTALL_PATH/lib or $INSTALL_PATH/lib/yourappname
man pages go in $INSTALL_PATH/share/man/man1 and possibly other sections if appropriate
other docs go in $INSTALL_PATH/share/yourappname
default configuration files go in $INSTALL_PATH/etc/yourappname
headers for other to link against go in $INSTALL_PATH/include/yourappname
Installation path
The INSTALL_PATH is an input to the build system, and usually defaults to /usr/local. This gives your user the flexibility to install under their $HOME without needing elevated permission.
In the simplest case just use
INSTALL_PATH?=/usr/local
at the top of the makefile. Then the user can override it by setting an environment variable in their shell.
Deinstallation
You also occasionally see make installs that build a manifest to help with de-installation. The manifest can even be written as a script to do the work.
Another approach is just to have a make uninstall that looks for the things make install places, and removes them if they exist.
In the simplest case you just copy the newly created executable into the /usr/local/bin path. Of course, it's usually more complicated than that.
Notice that most of these operations require special rights, which is why make install is usually invoked using sudo.
make install is usually the step that "installs" the binary into the correct place.
For example, when compiling Vim, make install may place it in /usr/local/bin
Not all Makefiles have a make install
