Gdal compiling the C # development version

Gdal compilation is troublesome, there are many kinds of things, today I compile the gdal encountered problems and the previous a bit different, for reference only.

1. Download Gdal Source code

Gdal Source: Https://trac.osgeo.org/gdal/wiki/DownloadSource

I downloaded the latest gdal211, I do not know why, the later compiled is the version of gdal201.

2. Start compiling the development version of C + +

Gdal method provided in window compilation: Http://trac.osgeo.org/gdal/wiki/BuildingOnWindows

To compile the 64-bit gdal, I modified the code at line 189 of the nmake.opt file to change the #WIN64 =yes to win64=yes

Then use CMD to set the compilation environment:

" C:\Program Files (x86) \microsoft Visual Studio 10.0\vc\vcvarsall.bat " AMD64

Then go to the Gdal directory and execute the following command in turn:

1, c:\gdal> nmake/f MAKEFILE.VC2, C:\GDAL> NMAKE/F makefile.vc install3, C:\GDAL> nmake/f MAKEFILE.VC Devinstall

After compiling, the Warmerda folder is generated below the C drive, and the files are used to provide C + + compilation, such as:

Note: If the compilation environment is set incorrectly, the following error will be prompted when the first step is compiled:

3. Compiling the version used by C #

Compiling the version used by C # requires the Swig tool, as follows: Http://prdownloads.sourceforge.net/swig/swigwin-3.0.10.zip

After downloading, unpack, open nmake.opt, change swig=swig.exe to Swig =e:\swigwin-3.0.10\swig.exe

Then go to the Swig\csharp directory and execute the following command after the above three sentences are compiled:

1. NMAKE/F makefile.vc Install

Note: The following issue occurs during the 1 compilation:

Learn from Blog: gdal compile C#,python support errors

Issue 1, interface redefinition

Osr\osrpinvoke.cs (192): Error CS0111: Type "OSGeo.OSR.OsrPINVOKE" has defined a named "Osrpinvoke" Members with the same parameter type
Osr\osrpinvoke.cs (188): (the symbol position associated with the previous error) Nmake:fatal error U1077: "C:\Windows\Microsoft.NET\ Framework\v4. 0.30319\CSC. EXE ": Return code"0x1"

Workaround: Enter into the. \GDAL-1.9.2\SWIG\CSHARP\GDAL|OGR|OSR three folders, find GdalPINVOKE.cs, OgrPINVOKE.cs, OsrPINVOKE.cs, remove the duplicate parameter types from the prompt, such as the following error:

Issue 2: interface member name called Error, error message:

Gdal\band.cs (+
Gdal\dataset.cs (+)
Gdal\driver.cs (,Bayi
Nmake:fatal error U1077: "C:\Windows\Microsoft.NET\Framework\v4. 0.30319\CSC. EXE ": Return code"0x1"

The GdalPINVOKE.cs defines the interface as follows:

The band class (for example) is called as follows:

Modify the interfaces in the three classes to:

 PublicDriver (IntPtr cPtr,BOOLCmemoryown,ObjectParent):Base(Gdalpinvoke.driver_swigupcast (CPTR), Cmemoryown, parent) {swigcptr =NewHandleRef ( This, CPTR);

 PublicDataset (IntPtr cPtr,BOOLCmemoryown,ObjectParent):Base(Gdalpinvoke.dataset_swigupcast (CPTR), Cmemoryown, parent) {swigcptr =NewHandleRef ( This, CPTR);

 PublicBand (IntPtr cPtr,BOOLCmemoryown,ObjectParent):Base(Gdalpinvoke.band_swigupcast (CPTR), Cmemoryown, parent) {swigcptr =NewHandleRef ( This, CPTR);

After the modification can be compiled successfully, after the successful compilation, the C:\warmerda\bld folder will generate a Scharp file for C # programming use.

4. Test procedure Error

1. Error occurred while testing program registered Gdal

Additional Information: Security transparency Method "OSGeo.GDAL.Gdal.AllRegister ()" Attempts to invoke native code through method "OSGeo.GDAL.GdalPINVOKE.AllRegister ()" failed. Methods must be security-critical or security-critical to invoke native code.

Workaround:

Modify the C # wrapper class code generated by Swig, which is forced to be declared as callable by security-transparent code. \swig\csharp\gdal\gdal.cs class and. The \swig\csharp\gdal\dataset.cs class, for example, adds the following two lines of code at the beginning of its class declaration:

using System.Security; [SecuritySafeCritical]

As follows:

If the problem still occurs, add [securitysafecritical].

2. An error occurred after the test program was successful:

Workaround, add [securitysafecritical] to the geometry Dispose method, as shown in

Similar problem resolution methods are the same.
