I needed to install Net:SSH2 in a Cygwin environment under Windows 7 (64 bit). As usually I tried to install it with cpanm.
I already had the necessary Cygwin packages (see below) installed but the Perl build failed because it couldn't find the libssh2 library.
There is a special text file BUILDING.WIN32 in the Net::SSH2 package but this is only useful when building the module by hand and it refers mainly to MinGW. So this no help.
This is the log of the build:
Entering Net-SSH2-0.53
Checking configure dependencies from META.yml
Checking if you have ExtUtils::MakeMaker 6.59 ... Yes (7.02)
Running Makefile.PL
Configuring Net-SSH2-0.53 ... Subroutine checklibs redefined at inc/Module/Install/CheckLib.pm line 11.

The libssh2 library is required by this module. If you don't have it, you can
download it from http://www.libssh2.org; you may also need OpenSSL, which can
be obtained from http://www.openssl.org , or libgcrypt, which can be obtained
from http://www.gnupg.org .
Debian: sudo aptitude install libssh2-1-dev
OpenSUSE: sudo zypper in libssh2-1 libssh2-devel
You can pass your libssh2 lib and include dirs (and extra link args) on the
command line. E.g.:
perl Makefile.PL lib=$HOME/libssh2/lib inc=$HOME/libssh2/include \
ldargs="-lz"
These can also be set through the LIBSSH2_LIB/LIBSSH2_INCLUDE/LIBSSH2_LDARGS
environment variables.
To build with libgcrypt instead of OpenSSL, pass 'gcrypt' as a parameter to
Makefile.PL, e.g.:
perl Makefile.PL gcrypt
If you want to build on Windows, see the file BUILDING.WIN32 in the
distribution.
Can't link/include C library 'ssh2', aborting.
First install the libssh2-devel package from Cygwin, e.g. with apt-cyg the command line frontend for installing packages from within a cygwin shell.
apt-cyg install libssh2-devel
Then set some environment variables to the right path for getting Net::SSH2 to work with the Cygwin packages:
LIBSSH2_LIB=/usr/lib/ LIBSSH2_INCLUDE=/usr/include/ cpanm -v Net::SSH2
That worked for me. Much easier than what the readme file linked above looked like.

I am trying to compile an OCaml .ml file with make command via command line remote machine but it shows me this error:
+ ocamlfind ocamlc -c -package xmlm -package unix -o pms.cmo pms.ml
ocamlfind: Package `xmlm' not found
Command exited with code 2.
Hint: Recursive traversal of subdirectories was not enabled for this build,
as the working directory does not look like an ocamlbuild project (no
'_tags' or 'myocamlbuild.ml' file). If you have modules in subdirectories,
you should add the option "-r" or create an empty '_tags' file.
To enable recursive traversal for some subdirectories only, you can use the
following '_tags' file:
true: -traverse
<dir1> or <dir2>: traverse

I tried to export the environment with this command:
eval $(/usr/bin/opam config env --root=/path/Ocaml/opam-ocaml-4.04-strech)
But also I had this error :
# opam-version 1.2.2
# os linux
File /p/opas/src/Ocaml/opam-ocaml-4.04-strech/config does not exist
while the config file does exist in the directory
any help Please ?!!
Thank you
To make a package available via opam (assuming that opam is properly installed and configured) you need to:
install the package
activate your opam
To install a package named foo, execute the following command in your shell
opam install foo
To activate your opam installation (which enables the search paths), issue the following command
eval $(opam config env)
or, with modern opam (that is of version 2.x) just eval $(opam env)
Before doing this, you need to properly initialize your opam installation, i.e., to install the compiler (or use the system compiler) and the base packages. This is done via the opam init command that creates an opam-managed subdirectory in your home, e.g., using an (old by today's standards) OCaml version 4.04.0, you can initialize it like this
opam init --comp=4.04.0
once the initialization is finished, do not forget to activate it via eval $(opam config env) and now you can install the package.
Finally, the version of opam that you're using is outdated and long ago deprecated, thus it is not receiving updates and the repositories that this version can understand are frozen and no longer updated. You really need to update your opam to a 2.x version. Please follow the opam installation instructions to get the latest version.
I installed Rakudo, the Perl 6 interpreter, by:
sudo apt-get install rakudo
I am following a tutorial about installation of Perl 6 modules:
http://perl6maven.com/how-to-install-perl6-modules
And in the last step I get this error:
perl6 bootstrap.pl===SORRY!=== Error while compiling /home/daniel/test/panda/bootstrap.pl
No compiler available for Perl v6.c
at /home/daniel/test/panda/bootstrap.pl:3
------> use v6.c⏏;
Information about versions:
Ubuntu 16.04.2 LTS
This is perl6 version 2015.11 built on MoarVM version 2015.11
How do I install the lacking compiler?
Warning: This solution can be used for development, but for production it is recommended to manually compile the interpreter until the Ubuntu repository will not be updated.
Panda described in the linked tutorial is depreciated. I should use zef to install Perl modules.
My build of Perl was too old. I realized this after reading issue 380 about not working version 6.c.
The correct tutorial about installation of the newest Perl, 6.c, on Ubuntu is here:
http://linuxtot.com/installing-perl-6-on-debian-or-ubuntu/
Now my rakudo -v prints:
This is Rakudo version 2017.07-132-gabf1cfe built on MoarVM version 2017.07-318-g604da4d
implementing Perl 6.c.
And everything works great.
The below commands are extracted from a tutorial linked below:
apt-get install build-essential git libssl-dev
git clone https://github.com/tadzik/rakudobrew ~/.rakudobrew
echo 'export PATH=~/.rakudobrew/bin:$PATH' >> ~/.bashrc
source ~/.bashrc
rakudobrew build moar
rakudobrew build zef
Now to install the perl6 module:
zef install Module::Name
If you are comfortable installing your own software from source, then try the following (update the URL for the latest Rakudo Star from https://rakudo.perl6.org/downloads/star/):
wget -O rakudo-star-2017.07.tar.gz https://rakudo.perl6.org/downloads/star/rakudo-star-2017.07.tar.gz
tar -xvf rakudo-star-2017.07.tar.gz
cd rakudo-star-2017.07
perl Configure.pl --backend=moar --gen-moar
make
make rakudo-test
make install
Then add the following paths to your $PATH (replacing /path/to with the actual path, of course):
/path/to/rakudo-star-2017.07/install/bin
/path/to/rakudo-star-2017.07/install/share/perl6/site/bin
I use a module file for this:
#%Module1.0
## Metadata ###########################################
set this_module rakudo-star
set this_version 2017.07
set this_root /path/to/$this_module/$this_module-$this_version/install

Trying to compile Mapnik on OSX 10.8
So after I clone the Github repo, I go to run the configure command like so:
./configure and then get the error:
Checking for C++ library icuuc... no
Could not find required header or shared library for icuuc
and later:
Exiting... the following required dependencies were not found:
- icuuc (ICU C++ library | configure with ICU_LIBS & ICU_INCLUDES or use ICU_LIB_NAME to specify custom lib name | more info: http://site.icu-project.org/)
Looking at the Mapnik troubleshooting area for a solution: https://github.com/mapnik/mapnik/wiki/InstallationTroubleshooting
Says: Solution: If g++ is available then ICU must be in a custom location so set the paths to the libs and includes - ie. ICU_LIBS=/usr/local/lib and ICU_INCLUDES=/usr/local/include.
By running g++ from command line I get: i686-apple-darwin11-llvm-g++-4.2: no input files
So this means that g++ is available, but I have no idea how to go about setting the paths so that configure can find them.
ICU Libraries were installed by default or with homebrew, not sure which.
terminal: brew install icu4c
Warning: icu4c-51.1 already installed
Finding the icu4c install directory:
terminal: mdfind icu4c
/usr/local/Cellar/icu4c
You can add the path of your ICU_LIB/INCLUDE to your configure command:
./configure ICU_INCLUDES=/usr/local/Cellar/icu4c/include ICU_LIBS=/usr/local/Cellar/icu4c/lib
And for more help about configure on what options are accepted do:
./configure --help
For the installation reference, you can check this:
https://github.com/mapnik/mapnik/blob/v2.2.0/INSTALL.md
As per our discussion and my last comment something like the following might work.
export ICU_LIBS=/usr/local/Cellar/icu4c/lib
export ICU_INCLUDES=/usr/local/Cellar/icu4c/include
./configure
If you find same errors:
Checking for C++ library XXX... no
Follow the command
sudo apt-get install g++ libXXX-dev
Using tips (TAB button), you can see what XXX libraries you have available
sudo apt-get install libXXX(press double TAB)
I am attempting to install M2Crypto on a Windows XP platform. I have Python, easy_install and SWIG installed, but when I attempt to easy_install M2Crypto I get the following:
SWIG\_m2crypto.i(31) : Error: Unable to find 'openssl\opensslv.h'
SWIG\_m2crypto.i(45) : Error: Unable to find 'openssl\safestack.h'
SWIG\_evp.i(12) : Error: Unable to find 'openssl\opensslconf.h'
SWIG\_ec.i(7) : Error: Unable to find 'openssl\opensslconf.h'
error: Setup script exited with error: command 'swig.exe' failed with exit status 1
I have read elsewhere that people have suggested easy_install openssl-devel, but that simply tells me that there are no packages found with that name. Is the name perhaps case-sensitive (I've tried various permutations without success), or does that advice not apply to Windows?
I'm not looking for alternatives to M2Crypto. I am picking up some existing code that uses it, so I need to get my development environment to be able to run what's already written.
As jay stated in his answer you should try to build it from source. And I tried. The setup.py does not recognize the --openssl option. Looking at the output from the default setup.py I realized that the search location was c:\pkg and not c:\pkg\openssl.
The solution:
Download and install OpenSSL from Win32 OpenSSL
Copy the lib and include folders to c:\pkg
Check that swig.exe is available in your path
Run easy_install M2Crypto
Worked for me like a charm.
Had a similar problem. After downloading the source package of M2Crypto and reading the INSTALL file I found the following:
Differences when installing on Windows
--------------------------------------
Before building from source, you need to install OpenSSL's include files,
import libraries and DLLs. By default setup.py assumes that OpenSSL include
files are in ``c:\pkg\openssl\include``, and the import libraries
in ``c:\pkg\openssl\lib``. As with other platforms, you can specify a different
OpenSSL location with --openssl option to build_ext command.
My shared hosting is missing two Perl modules required by Amazon SES Scripts. They are:
Digest::SHA and XML::LibXML
I downloaded Digest::SHA from here and XML::LibXML from here
Extracted, and uploaded LibXML.pm and SHA.pm to my custome directory (my_perl_lib).
I have added:
use lib "/var/chroot/home/content/09/6758009/html/my_perl_lib";
to the second line to the perl script.
I get this:
Can't locate XML/LibXML.pm in #INC (#INC contains: /var/chroot/home/content/09/6758009

Please advise.
Updated:
thanks, i created the directory, the error gone, but i faced another one:
Can't locate loadable object for module XML::LibXML in #INC (#INC contains: /var/chroot

Updated:
thanks again for your reply.
here are the results:
-bash-3.2$ perl Makefile.PL INSTALL_BASE=/var/chroot/home/content/09/6758009/html/my_perl_lib
enable native perl UTF8
running xml2-config...ok (2.6.26)
looking for -lxml2... no
looking for -llibxml2... no
libxml2 not found
Try setting LIBS and INC values on the command line
Or get libxml2 from
http://xmlsoft.org/
If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.
Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter
to see the exact reason why the detection of libxml2 installation
failed or why Makefile.PL was not able to compile a test program.
-bash-3.2$
It needs to be inside an "XML" directory... IE, make sure that LibXML.pm is actually in /var/chroot/home/content/09/6758009/html/my_perl_lib/XML/LibXML.pm.
Updated:
You probably need to do a full local install of the perl module, and the shared object that accompanies it. You can do this by using:
# extract sources
# cd source-directory
# perl Makefile.PL INSTALL_BASE=/var/chroot/home/content/09/6758009/html/my_perl_lib
# make
# make install
This will install everything needed into that directory. Then in the script, reference both of these paths:
use lib '/var/chroot/home/content/09/6758009/html/my_perl_lib/lib/perl5';
use lib '/var/chroot/home/content/09/6758009/html/my_perl_lib/lib/perl5/i386-linux-thread-multi/auto';
Note that you'll likely need to change the architecture of the i386-linux-thread-multi part of that line. That's where the .so file is installed.
