Im facing the problem during installation :
>>setup configure
Configuring HDBC-sqlite3-2.3.0.0...
setup: Missing dependency on a foreign library:
* Missing C library: sqlite3
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
what should I do ?
thanks for any help
OK,
I downloaded sqlite3.dll and sqlite3.h from source zip.
then I inserted sqlite3.dll in system32 dir and in setup configure i used
--extra-lib-dirs=... --extra-include-dirs=... parameters with correct paths to header and dll.
You need to install the C library implementation and headers of SQLite.
On Ubuntu and other Debian-based Linux distros, it's simply
sudo apt-get install sqlite3 libsqlite3-dev
Other Linux distros will have similarly named packages.
On Windows, you'll have to do some more work.
On OS X, I have no idea.

I have installed qt-creator on windows 10 using msys2.
I installed packages according to https://wiki.qt.io/MSYS2
base-devel git mercurial cvs wget p7zip
perl ruby python2 mingw-w64-i686-toolchain mingw-w64-x86_64-toolchain
mingw-w64-i686-qt-creator mingw-w64-x86_64-qt-creator
I had previously installed qt from the official site but the mingw version is too old and I'd rather not have two mingw versions installed.
I have existing C:\msys64\mingw64\share\qt5\examples folder but it seems there are some folders missing from C:\msys64\mingw64\share\qt5\doc compared to the official install. Maybe that has something to do with it.
So the question: Is there a specific package I need to install so that the examples show up in the qt-creator examples page or something else?
I found in this place https://www.archlinux.org/packages/extra/any/qt5-examples/
decompress with
zstd -df qt5-examples-5.14.2-1-any.pkg.tar.zst
and then
tar xzf qt5-examples-5.14.2-1-any.pkg.tar
the examples are saved in /usr/share/doc/qt/examp,es
The qt-creator in msys2 distribution do not have examples installed. The msys2 also do not have separate package for it.
But as what #user3930978 found. You can use example package from archlinux site for workaround.
But unfortunately, msys2 qt5 configured with "-nomake examples" parameter. You need to modify generated file. The easiest way is still to install qt5 and creator with official full pack.
I am using R on Windows to connect to a PostgreSQL database hosted on AWS. The database is set up using forcessl = 1 - this means that any connection needs to be set up with sslmode=require.
The base RPostgreSQL package does not provide any exposure to ssl options. This has been raised as an issue many times (see here, here, here and here)
I know there is a workaround using the RPostgres package, but for other functionality reasons I would much prefer to use the RPostgreSQL package.
A few answers (e.g. here) have proposed using a modified dbname to connect with ssl like so:
dbConnect(dbDriver('PostgreSQL'),
dbname = 'dbname=foobar sslmode=require', # modified dbname
host = 'foobar.rds.amazonaws.com',
port = 5439,
user = 'foobar',
password = 'foobar')
But this did not work for me using the CRAN version of the package. This led me to a recent issue raised on the RPostgreSQL github: https://github.com/tomoakin/RPostgreSQL/issues/88
The initial user was able to use the modified dbname method when he compiled the package from source. On Windows, using the latest source package (0.6.2) compiled with RTools, I get the following error when I run the modified dbname code:
Error in postgresqlNewConnection(drv, ...) :
RS-DBI driver: (could not connect xxxxx.rds.amazonawss.com:5432 on dbname "xxxxxxx": sslmode value "require" invalid when SSL support is not compiled in
)
From this and the rest of the thread, it looks like SSL is not possible from current source in both Windows and Mac. However, the developer suggests:
If you compile in a environment where libssl and libpq was made SSL activated form, then the driver can use SSL.
I think this means I could manually download the libs and compile myself, but I am not sure if it is a quick fix or if it would require significant rewriting of the package. Any help or pointing in the right direction would be much appreciated. How can I do this in a safe, repeatable way?
I was able to solve this for the El Capitan macOS R users in my office, by doing the following:
Remove RPostgreSQL R package if you already have installed. Methods vary on how to do this, but from either R.app console or R in Terminal, type remove.packages('RPostgreSQL')
Make sure you have Homebrew installed, and from Terminal run: brew install libpq openssl
Open R.app, and from the Packages & Data menu, select Package Installer.
From the first drop-down menu, choose CRAN (sources) (choose mirror closest to you if you haven't used this before).
Using package search, find RPostgreSQL and for the options below, keep At System Level checked, and check Install Dependencies, then click Install Selected.
Quit out of all R and RStudio programs, and try using the new from source installed RPostgreSQL package.
DISCLAIMER: If you have heavy compile dependencies on OpenSSL or libpq for other programs, I have no idea how doing the above may break other programs.
Building on Windows is a can of worms. See R-Admin Windows Toolset. The only openSSL binaries for windows are from unknown developers. Building and installing openSSL on windows is another can of worms that you will need to research. It might be easier to install openSSL inside the R Windows build environment, but I have no experience with that.
EDIT: It turns out that when installing postgres on Windows, postgres installs openSSL. That means that the central problem on Windows is installing the Windows Toolset for R, installing postgres, then pointing the R build system to libpq.
Another solution would be to run linux in a virtual machine under windows. Here is one way to Install linux on Windows. With linux, depending on the distribution, you would only need to do something like the following from the linux command line (for a RedHat variant of linux):
sudo yum install openSSL
sudo yum install postgresql96
sudo yum install R
Line 2 installs libpq which is required for RPostgreSQL. It is libpq which must be compiled with openSSL. You will only be installing and using the PostgreSQL client, not the server and will also get psql. There might be other packages required, see R linux toolset. Normally, these will get pulled in with the above and should not be a problem.
RPostgreSQL contains a version of libpq, but the compile script does not look like it checks for openSSL, at least not on macOS. So it is important to get a system provided libpq installed.
It is also important for the RPostgreSQL configure script to find pg_config, which is installed when postgres client is installed. Not sure about windows through. So make sure pg_config is in your path. Type pg_config to find out.
Now you need to download and compile RPostgreSQL. To start R, type the following at the linux terminal.
R
Then from within R, get, compile and install RPostgreSQL:
install.packages("https://cran.r-project.org/src/contrib/RPostgreSQL_0.6-2.tar.gz", repo=NULL, type="source")
This should compile and install this version of RPostgreSQL. This last line should also work in windows if you have the windows tools installed correctly.
Hopefully, this gives you some ideas.
Now a bit of background of my current setup:
I have Python3.3 running on Centos 6. I'm currently working on a web application using Flask that runs on Apache 2.2.15 with mode WSGI 4.5.3 and virtualenv 15.0.2.
pip --version pip 8.1.2 from /usr/local/bin/lib/python3.3/site-packages (python 3.3)
I have installed pysvn with pip and when I run pip show pysvn says
Location: /usr/local/bin/lib/python3.3/site-packages
755 permissions recursively set to /usr/local/bin/lib/python3.3/site-packages. And I passed --system-site-packages argument to virtualenv to use the global site packages.
Even when I try to import the package from python interpreter it does not work. So it is not specific to my virtualenv setup but rather a global problem.
I must mention that other packages installed with pip work perfectly fine (i.e. flask).
I've exhausted all other avenues before coming forward to you guys. Any suggestion would be highly appreciated as I ran out of ideas.
L.E.
I did manage to install it in the end. I'm not completly sure yet why and how but I presume is was compatibility issue.
First of all I have uninstalled svn 1.6+ and installed version 1.8.16 instead which seems to be tested against the latest two versions.
Second, I have uninstalled the troublesome pysvn instance and installed pysvn-1.8.0 workbench "sudo /var/www/FlaskApp/FlaskApp/flask/bin/pip install pysvn-1.8.0.tar.gz". In this case I have installed it my local environment. The 1.9.0 version of pysvn did not work.
L.L.E.
False positive, still doesn't work. I'm going to interact with svn via command line from my script.
L.L.L.E.
After installing svn 1.8.16 and svn-devel along with the rest of dependencies described in the readme file I have managed to successfully install it from the source fallowing the instructions.
Thanks for your help Barry.
pysvn is not available from PyPI because PyPI has no way to allow me to upload pysvn for each supported SVN version. Let alone deal with the issues of installing on a Linux distro given the choices for pysvn dependencies.
(APR, SVN, OpenSSL etc).
Fedora packages pysvn for the Fedora release.
I'm assuming that means it is on RHEL and therefore packaged by CentOS.
(But I do not have RHEL or CentOS to check this on)
If you find that a package is not available for your CentOs is not hard
to build pysvn on a linux distro. Get the source kit and follow the readme.html should get you going.

I want to compile PhantomJS with gstreamer. I downloaded the source code and started the build process with
./build.sh --qmake-args WEBKIT_CONFIG+='use_gstreamer'
I get the following Error
Project ERROR: gstreamer-1.0 development package not found
I have an debian 8.0 system with installed libgstreamer1.0 and glib2.0 (installed with apt-get).
Can someone help me?
If you haven't installed them, you'll need the development packages as well which should be something like libgstreamer(X.X.X)-dev, where X.X.X is whichever version of gstreamer you have installed. The development package has the necessary header files required for compilation.
you may need to modify the build script to add "{GStreamerInstallDir}/1.0/{architecture}/lib/pkgconfig" to the CMAKE_MODULE_PATH configuration so cmake can find the package.
Not sure how to do this in your environment as I build on a windows OS where I just specify this using an environment variable from a wrapping batch script.
i am trying to install RODBC with the commadn R CMD INSTALL -l /my/local/path RODBC.tar.gz and it wont find sql.h and sqlext.h ..how do i pass the include and lib paths to this command?
I had a similar problem recently while trying to install RODBC on an instance of Centos 5.8 x64. (Instead of using R CMD install, I just did sudo R, then installed the package inside R - but I was still having the same problem).
I resolved this by installing the following packages using yum:
unixODBC
unixODBC-libs
unixODBC-devel
mysql-connector-odbc
freetds
freetds-devel
Those last two are necessary because I was interfacing with an MSSQL server, which requires TDS. Anyway, once I installed unixODBC and the libs and development package, I was able to install RODBC with no difficulty (again, using sudo R and then install.packages("RODBC").
The only other thing to do is install the correct drivers/libraries for ODBC, which is what mysql-connector-odbc is. You will need to configure unixODBC to meet your needs, but the documentation is pretty solid, so I don't think you'll have too much difficulty.
