MySQL C API libraries for iPhone - mysql

Does anybody know where to get a MySQL libraries compiled for the arm iPhone architecture?
Or how to cross-compile MySQL for arm?
Thanx

Here's how I did it:
1) Download the source code version of Connector/C from MySQL
2) Download cmake (if you have macports installed, type "sudo port install cmake")
3) Get toolchain files from http://sites.google.com/site/michaelsafyan/coding/resources/how-to-guides/cross-compile-for-the-iphone/how-to-cross-compile-for-the-iphone-using-cmake
4) In the toolchain file for the simulator, remove one architecture from the line containing CMAKE_OSX_ARCHITECTURES
5) If you want to build for the simulator, copy the missing headers in /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/usr/include/netinet/ (ip.h and in_system.h) from /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/include/netinet
6) Create a directory called "compiled_library" somewhere, eg on your Desktop
7) Call cmake like this:
cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/iphone-toolchain-file -DCMAKE_INSTALL_PREFIX=/path/to/compiled_library -DHAVE_FDATASYNC:INTERNAL=0
8) Note that if you want to run cmake a 2nd time, you might have to delete the cache file first
9) type make install
10) Now you have the compiled library in /path/to/compiled_library. Copy the header file directory and libmysql.a to your xcode project via "Add existing files...". The library should be automtically added to the linker stage.
11) WOOHOO. Use the mysql C API.
12) If this is too much work, I'm currently writing a MySQL wrapper framework for the iPhone. I will publish it sometime in the next ten years and put a link here.
EDIT:
Someone else created an Objective C Wrapper for the MySQL client library: http://www.karlkraft.com/index.php/2010/09/17/mysql-for-iphone-and-osx/

do you need client or server libraries? Anyway, since OS X supports unix scripts you should at least try build using "regular Unix" approach:
client:
http://dev.mysql.com/doc/refman/5.1/en/connector-c-building.html
server:
http://dev.mysql.com/doc/refman/5.1/en/installing-source.html

You can use Kumulos 'Hookup' http://www.kumulos.com/2011/07/06/introducing-hookup/ feature to build a suite of web services for your MySQL database.
Basically you define your different web services in the online control panel, then it builds all the Objective-C code and server side code.
I believe this is the easiest way to achieve your goals, and probably a lot better than using a direct Objective-C MySQL library.

This worked for me:
https://github.com/thrivesmart/just-mysql-example-mac-app-objective-c-xcode/issues/1
No compilation needed
Just use that LIB and replace the lib with the other repo!

I don't believe you can run MySQL on the iPhone. As Ben pointed out SQLite is built into the iPhone and you can use Core Data to manage structured data.

how to run dotnet core's standalone program on mac

a rudimentary question, but please let me know.
I want to run the following program which will process and return the result by json when accessed by GET or POST.
FileManagerController.cs
For example, in PHP you just need to place it in the htdocs folder of Apache.
I would like to do the same thing with dot net core mvc.
but I don't know what kind of words to search.
Also, in the near future we would like ruby to work the same way in another project.(In a way that doesn't use a framework such as rails)
So, please tell me how to find out how to run various languages alone on a web server.
You need to make a "project" (file type .csproj) that you can build and run on your machine. Check out the Getting Started with ASP.NET page for instructions to install the SDK and create a new project and run it.
To run your code file above, you can:
$ dotnet new mvc
Copy the above FileManagerController.cs file into the generated Controllers folder.
$ dotnet run
Your app will be running on http://localhost:5000, you can hit your web site using the url /FileManager.

MySQL Install the UDF library "mysqludf_sys" on a Windows Server 2016

For 2 weeks I'm looking for a proper tutorial on how to fully install the library "lib_mysqludf_sys".
I got the .dll from a Russian site, because there seems to be no other for 64bit systems. I have successfully installed the procedure and also created the function, but whenever I want to call a file the whole database crashes. I conclude that the DLL file is faulty or that I forgot something to install.
can someone please explain to me how to use the UDF library to call files on a Windows Server 2016 64bit properly implied in the MySQL?
that would help me a lot, thank you!
Download the Windows 64 bit version from here:
https://github.com/rapid7/metasploit-framework/tree/master/data/exploits/mysql
Copy it to here or equivalent for your MySQL installation:
c:\Program Files\MySQL\MySQL Server 5.7\lib\plugin\lib_mysqludf_sys_64.dll
Install and verify as per the instructions here:
https://osandamalith.com/2018/02/11/mysql-udf-exploitation/
Looks like you are using MySQL 57/earlier version. For the library, I suggest to control it with "dependency walker". See if there is any problem with dependency libraries. At lease KERNEL32.DLL and MSCVTR.DLL (Visual C++ Redistrubatable file) should be there without any warning on root level.
If you have the code, I suggest you to recompile it with mygwin64. There are many items needs to be fixed to compiled it. Following link is a good link for UDF DLL compiles

There something similar, follow my answer here

Compiling sqlite-winrt for using SQL in WinRT/WP app with SQLite

I'm trying to use the sqlite-winrt library at https://sqlwinrt.codeplex.com (cf. http://blogs.windows.com/windows_phone/b/wpdev/archive/2013/05/30/sqlite-winrt-wrapper-for-windows-phone.aspx) because I need to access an SQLite database via SQL commands in a WinRT 8.1 and a WP8 app and this library seems the only available option.
Anyway, there is no binary release and if I try compiling the source I get several link errors for unresolved externals against the SQLite DLL. I posted an issue at codeplex but got no reply yet, so I was wondering if anyone had already managed to successfully compile this lib and how (or if you know of any viable alternative for RT8.1 and WP8). Here is what I did:
downloaded the latest source from the site.
downloaded and installed 2 VSIX from http://www.sqlite.org/download.html: sqlite-winrt81-3080002.vsix for RT 8.1 and sqlite-wp80-winrt-3080100.vsix for WP.
executed the powershell scripts in each subfolder of the source code solution, which are required to update the projects with newer releases of the SQLite for WinRT extension. The current versions of the scripts refer to SQLite for WinRT 8.1 (prerelease) which is the same I downloaded above.
opened the VS2013 solution and removed the RT project (I just need RT8.1 and WP, this was for WinRT 8.0).
5) built the solution, which failed with link errors.
If I see the RT8.1 project properties, I can confirm the reference to SQLite is under C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1\ExtensionSDKs\SQLite.WinRT81\3.8.0.2.
Did anyone manage to use this lib? Thanks!
I also once had that problem. I fix it by editing the project file manually. At that time, the powershell script updating the wrong path. That's why I always failed when compiling my project. After I edit the project file using external text editor (I use sublime text), the projects are linked correctly.
You can try DatabasesCx. It is another SQLite Wrapper using Windows Runtime Component technology. It is freeware distributed as precompiled binary. You can find the details at http://www.almanacsoft.com/databasescx

How to build OpenSSL for WP8?

How to build OpenSSL for WP8?
AFAIK, we must replace winsock.h by winsock2.h because WP8 only supports winsock2.h. And maybe we must replaces code to target WinRT architecture on WP8 (ThreadPool, ...)
The caveat is that we must build OpenSSL as WP8 static library, so that the output lib can be wrapped by WP8 runtime component, right ?
You can use the Microsoft openssl fork on github with support for windows phone 8.1/8.0 and Windows Store 8.1, that address the entropy on each platform using windows random generators, instructions are located at INSTALL.WINAPP, there is a script located at
ms\do_vsprojects.bat
you should be able to just execute that script withing the root location and open vsout\openssl.sln to build the openssl libraries for different windows platforms.
The fork is located at
https://github.com/microsoft/openssl
At this momment these changes are being in process to be integrated with the main OpenSSL source code base.
here is what you have to do, go to this link and download the VSbuild, now put that into the source files downloaded from the OpenSSL website, the folder structure should look like this:
apps
bugs
certs
.....
vsbuild
once that is done, open the solution, it should upgrade it to VS12, change the settings to a Windows Phone RT build, to generate DLL's there is no need to build *_lib*, so change the other projects, most changes you need to do are to libeay32, do not compile openssl project, just ignore that, start by building libeay32, and start making changes to the code, as there are some functions we don't have in WinRT, you can either #ifdef them out, or create your own functions,
NOTE for rand_win.c change the functions to use rand_s and #ifdef most of the code there is, this might muck up the security, you will have to test it out yourself
Good Luck !
This is so that if anyone wants to build the new version of OpenSSL "1.0.1g" that fixes the Heartbleed problem you can follow the previous steps whit the following changes:
I renamed the folder include to --include and create a new folder named include, the VS project will take care of copying the information, --include if you like you can remove this, when i build the project without this change there where compilation issues.
Note: the include folder that i changed is the one found in the root not the one found under VSbuild
Enjoy
Here is a download of pre-compiled OpenSSL libraries for Windows Phone 8.1 among other platforms:

MySQL++ Application error at launch

I compiled MySQL++ with no issues. When I launched some of the executables (resetdb.exe and simple1.exe) they suggest to run to test if the installation has been successful, the first error I got was that libmysql.dll was missing.
Adding its path to the PATH environment variable did not fix the problem, even after launching a new command prompt; I had to copy the DLL in the directory where MySQL++ executables are.
Now the DLL is found, but I get this error:
simple1.exe - Application error
The application was unable to start correctly (0xc000007b).
Click OK to close the application.
even launching from the command line, I get no more information than these.
Thank you for any help!
MySQL 5.5 -
MySQL++ 3.0.9 -
Windows 7 64 bits -
MINGW32 -
GCC 4.4.0
0xC000007B is a Windows error that means the executable is corrupted. It could refer either to simple1.exe or to one of the DLLs it's linking against.
Some reasons this could happen:
You're mixing toolchains in an incompatible way. In your case, you may have built simple1.exe using pieces built by MinGW GCC and pieces built by Visual C++. MinGW should be compatible with any pure C DLL built by Visual C++, including the MySQL C API DLL. However, you may have other pieces interfering. MinGW isn't compatible with VC++ at the C++ level, but then, it shouldn't have linked at all if this were your problem.
You didn't follow the MySQL C API import library build steps in README-MinGW.txt. You either missed a step, or skipped it entirely and are trying to use the import library that shipped with MySQL.
In your previous gyrations, you ended up with a corrupt object file, which got linked in. Try saying make clean all at the top level of MySQL++ to force a complete rebuild.
You're mixing versions of MySQL or MySQL++. If you have more than one version of each on the system, make sure you're consistent in their use. That is, build the C API import library from the same DLL you run the programs against, use exrun.bat to run the examples to ensure you're using the just-built version of the MySQL++ DLL instead of another you have in your PATH, etc.
Additionally, I note that you're using an older version of MySQL++. If you were on Linux, I could understand that as some distributions still ship with 3.0.9. But since you have to build MySQL++ from source with MinGW, I don't see why you're not using 3.1.0. Did you get a binary build from somewhere?
As for your PATH problem, did you restart the MinGW shell after doing this? PATH updates don't affect running programs; they keep the value they saw when they started.
