I installed erlang from erlang.org using
wget http://erlang.org/download/otp_src_R16B03.tar.gz
I can see that erlang is successfully installed. However, I am unable to use the erlc command for eg,
ercl file.erl
{"init terminating in do_boot",{undef,[{erl_compile,compile_cmdline,[],[]},{init,start_it,1,[]},{init,start_em,1,[]}]}}
Crash dump was written to: erl_crash.dump
init terminating in do_boot ()
Also, I tried to create a symlink for this new install.
which erl
/usr/local/bin/erl
ls -al /usr/local/bin/erl
lrwxr-xr-x 1 sad admin 45 May 25 12:00 /usr/local/bin/erl -> /Users/sad/erlang/otp_src_R16B03/bin/erl
Please help if there is anything Im missing
You have downloaded the source package, so you need to build and install first. See https://github.com/erlang/otp/blob/maint/HOWTO/INSTALL.md for details. Better yet, download a package already built for your platform. See for instance http://erlangcentral.org/downloads/
It looks like you're running out of the R16 build tree, and you maybe put the symlink(s) in /usr/local/bin manually? You can make that work by setting up your environment appropriately, and it's probably not what you want.
Instead, after building (and possibly smoke testing) you should run make install in the build tree to install it properly to /usr/local or whatever directory you specified with the --prefix flag to ./configure or ./otp_build.
I recommend that you keep a fairly current version (current version is 18.3) in /usr/local and, if you need to use older versions like R16, keep them in a separate location.

I'm trying to install the mips-linux-gnu-gcc Toolchain on Debian 7 from a guide, which has the instructions to install it from a directory on the machine (which I already sent in) and has the following command to do so:
export PATH=toolchain/bin/path:$PATH
and the next step is to check it's version:
mips-linux-gnu-gcc --version
But the only result I have is the "command not found result", I made sure the files are inside the folder and they are, and checking the mips-linux-gnu-gcc file I have the following result:
Am I doing something wrong? I have no experience with this kind of files and I haven't found any other way to install it, so I really need help with this :/
I solved it! the problem was the directory that I was exporting to PATH, since I installed everything on the root folder I had to put /root/ at the start of the url indicated in the instruction guide.
I'm working on a Windows 7 computer at work and want to use the libpostal package. Unfortunately, it's apparently not available for Windows, so I'm trying to configure it through Cygwin and I'm SO close. The last step is to install snappy from Google. Again, not available on Windows...
My assumption (based on nothing) is that I can just download the tarball and build it from source, right? I tried that, and I think it worked? But a) I don't know how to tell, and b) if it did, I don't know how to tell ./configure in libpostal to find it.
In order to build it from source, I downloaded the tarball and saved it in the folder that Cygwin reads as my home, which is C:\cygwin64\home\brittenb\. From there, I ran bash autogen.sh, which created the ./configure that I needed. So I ran that and while some responses to the checks were no, it seemed to run fine. I then ran make and make install. Nothing seemed out of place, so my assumption is that it did what it was supposed to do. I just have no idea where to go from here.
Here is the output from ls after I run everything:

ls /usr/local/bin shows nothing, but ls /usr/local/include shows:
snappy.h snappy-c.h snappy-sinksource.h snappy-stubs-public.h
So... my question: did it work? Why does ./configure in libpostal say it can't find snappy? Thanks in advance.
The snappy dependency has been removed as of release 1.0.0. I made changes to the source and make and config so that it will build on MinGW.
Get it in my repository:
https://github.com/BenK10/libpostal_windows
Note that this is not the complete source since not everything had to be changed. I would suggest merging my changes with the official libpostal distribution to make sure you've got everything. Also, there are some extra DLLEXPORTs in some source files that I haven't removed yet, and the part in the Makefile that builds the executables like address_parser.exe was removed because some porting is necessary to build those programs on Windows. You can write your own using the DLL you'll get in the Windows build and the original source as a reference.
Check the return code from make install ($?). If it is zero, make install succeeded.
snappy looks like a library, so maybe it doesn't install anything in /usr/local/bin. The library is probably installed into /usr/local/lib.
I want to compile and run a specific version of a FreeBSD utility from the source code.
For example, I downloaded the repo for the following utility: https://svnweb.freebsd.org/base/stable/9/sbin/routed/
However, when I run the make command, I get the following error:
"../Makefile.inc", line 3: Cannot open ../Makefile.inc
make: fatal errors encountered -- cannot continue
*** [all] Error code 1
Can someone point me in the right direction?
You will need to download the whole source tree. The build system depends on pieces from different locations in the tree. Then;
Unpack the source in /usr/src
cd /usr/src/sbin/routed
make && make install
It looks like you want the 9-stable branch? If you have subversion available, you can do:
rm -rf /usr/src/
svn co svn://svn.freebsd.org/base/stable/9 /usr/src
(Depending on your FreeBSD version, svn may also be called svnlite) Also see the handbook.
On my machine, the complete /usr/src tree is 2445 MiB, including the .svn directory.
Edit: Note that it a program relies on system calls, library functions or other features that were introduced in a certain branch/version of FreeBSD, it will not work on older branches/versions.
I know that this should probably be very easy, and I have looked into the read me files and other files in cgdb like INSTALL that talk about isntalling cgdb. I was trying to install cgdb and the instructions said:
$ ./configure --prefix=/usr/local
$ make
$ sudo make install
However, there is no such file inside of the file I got from running the git clone command. i.e. from running:
$ git clone git://github.com/cgdb/cgdb.git
I went inside that file to see the installation instructions and it says the following:
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.
The file `configure.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
and there is more I didn't paste.
The part that confuses me is the following paragraph:
The file `configure.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
does it mean I should run ./configure.in? I am honeslty a little scared of running it because I need to run it in as sudo plus, that file doesn't even exit in the code I got from git clone. This is what I do have in that directory:
➜ cgdb git:(master) ls
AUTHORS Makefile.am autogen.sh doc roadmap.txt
COPYING NEWS autorelease.sh indent.sh test
ChangeLog README cgdb lib
FAQ README.md config packages
INSTALL TODO configure.init release-todo.txt
➜ cgdb git:(master)
I did grep for config or config.in in that directory and it didn't yield anything useful.
I have also tried brew installing it but I ran into problems. When I cgdb the file and hit run it frozen at a print statment instead of moving on to the next command prompt for gdb as in (gdb). Anyone knows whats up? Is it because I am using go source file?
What have people done to have cgdb working on a mac?
Неу, yeah, the git source for cgdb doesn't come with the configure script pre-built. (The official release distributions do, however.)
If you have the right tools installed, you can fix this by running:
./autogen.sh
This will generate the configure script, and then you can install it as you would any other autoconf-based source package.
Forget about all that aggro with configuration and dependency libraries; install MacPorts and do:
$ sudo port install cgdb
They have 0.6.7 at the time of writing.
What worked for me was doing:
brew install cgdb
However, for me that was not enough to get it going. I needed to sudo it for it to run:
sudo cgdb
I would have never guessed I needed to sudo it...I figured it out because it was throwing me the error talked about in the following question:
gdb fails with "Unable to find Mach task port for process-id" error
Is there a way to get a list of filenames/paths that make install copies to the filesystem? Some packages come with a MANIFEST file, but not the ones that I am working with.
I was just investigating this myself while compiling a custom version of QEMU. I used the following method to work out what was installed and where (as well as using it as a basis for a .deb file):
mkdir /tmp/installer
./configure --target-list=i386-softmmu
make
sudo make install DESTDIR=/tmp/installer
cd /tmp/installer
tree .
Tree is a utility that recursively displays the contents of a directory in a visually appealing manner - sudo apt-get install tree for Debian / Ubuntu users
Hope that helps someone... it took me a bit of poking around to nut it out, but I found it quite a useful way of visualising what was going on.
The most fool-proof way is to use chroot: have "make install" run inside a chroot jail; compute a list of the files that you had before the installation, and compare that to the list of files after the installation.
Many installations will support either a --prefix configuration option, and/or a DESTDIR environment variable. You can use those for a lighter-wait version of chroot (trusting that the installation will fail if it tries to write to a location outside these if you run installation as a fairly unprivileged user).
Another approach is to replace the install program. Many packages support an INSTALL environment variable that, well, is the install program to use; there are tracing versions of install around.
make uninstall might show the files as it removes them if the author of the compiling instructions provides the information to allow an uninstall (it has been awhile since I have done one so I can't say for sure).
Also make -n install will do a "dry run" of the install process and it may be reasonable to extract the information from its results.
It differs for every project that you run 'make install' on. The files which are installed are controlled by the install target in the Makefile being used. Your best bet is to open the Makefile and search for 'install:' - from there you can see what files will be copied out to your system.
Take a snapshot of the contents of the install location before installing
Install
Compare the current contents with the old contents.
Example:
./configure --prefix /usr/local
make -j`nproc`
find /usr/local | sort -u > /tmp/snapshot1
make install
find /usr/local | sort -u > /tmp/snapshot2
comm -3 /tmp/snapshot{1,2} # this prints the files added by `make install` to stdout
If the install program you're using doesn't support DESTDIR or --prefix (or an equivalent), I have found that it may be possible to identify new files as follows:
Start with as clean a system as possible (a fresh VM image is preferable)
Compile the software, wait a few minutes.
Install the software package.
Find files modified within the past 5 minutes: sudo find / -mmin -5 -type f (the find command has a ton of parameters for querying based on file modification / creation times, but this worked pretty well for me; you just need to narrow the time span so that you pick up the files created by the installer but nothing else).
