Downloading GX Developer for 9.3
Starting with the 9.3 platform release there is no longer a "download" from Geosoft. All developer resources are available on the Geosoft Inc. Github account. Different programming languages require resources specific to that language, as follows:
| Language | What you need | Resources |
|---|---|---|
| Python | Python extensions are installed to your Python environment using pip. You do not need to download anything more. See Python Quick-Start for more information. | For reference only - you do not need this: |
| Geosoft GXC | The GX compilers grc.exe and gxc.exe are now included in the Oasis montaj platform installation and do not need to be installed separately. The gxc header files and all Geosoft source code can be downloaded from GitHub. See GXC Quick-Start for more information. | https://github.com/GeosoftInc/gxc/releases |
| .NET (C# etc.) | .NET developers can use references to the GX.Net assemblies from the Geosoft Desktop Applications bin directory. The gxdotnet repository also contains an See .NET Quick-Start for more information. | |
| C/C++ | C and C++ headers, library files and redistributable DLL's can be downloaded from the gxcore release on GitHub. See C/C++ Quick-Start for more information. | https://github.com/GeosoftInc/gxcore/releases |
Version 9.2.1 :
- Corrected and improved some docstrings.
- Added iterator support to the geosoft.gxpy.Grid class.
- Fixed problems saving parameters to the parameter block when the parameter group does not already exist. Also added the ability to recognize default parameter settings from the initial dictionary settings.
If you already have the Geosoft package installed you should uninstall Geosoft, then install the latest version, as follows:
pip uninstall geosoft pip install geosoft
Alternately, you can update the Geosoft package in-place, which will also update any dependencies:
pip install geosoft --upgrade
Version 9.2 :
May 31, 2017
The Python geosoft.gxpy 9.2 revision includes many advances that make the api more consistent with current Python best practice, particularly around naming conventions and the consistent use of class instance properties and iterators. As a result, python scripts written for geosoft.gxpy 9.1 will need to be modified to conform to new naming conventions and the use of properties on some classes.
The base GX API, which is exposed to Python by the geosoft.gxapi module, is consistent across versions (9.0, 9.1 and 9.2). As a result, the geosoft.pxpy 9.1 will continue to work with Geosoft Desktop 9.2, though both the 9.1 and 9.2 api cannot exist in the same Python environment. While we recommend that your 9.1 scripts be updated to conform to the 9.2 api, should you do need support for both 9.1 and 9.2 you can create separate Anaconda Python environments for each version. For example, you might create an environment 'py35' for Python 3.5 and the GX API version 9.1, and 'py36' for Python 3.6 and GX Developer 9.2. If you are not using the 9.1 GX API at all, it is best to simply start with the GX API version 9.2 and either Python 3.6 (or Python 3.5 or 3.4 if other applications depend on earlier versions of Python)..
- Updated to conform to Oasis montaj 9.2 (see https://my.geosoft.com/downloads)
- Documentation refresh: GX Developer 9.2
- Added/verified support for 64-bit Python 3.5 and 3.6. Forward compatibility with future 64-bit Python is expected.
- Many new GX API methods introduced:
- Extensive revision and extension of gxpy, the Geosoft Python module that "pythonifies" the GX API:
Version 9.1 :
- Major documentation revision: GX Developer 9.1
- 64-bit Python 3.4 and higher support.
- Support for Python extensions to Oasis montaj (run a Python script just like a GX).
- Geosoft Python modules that abstract and simplify the GX API for Python development.
- New GX API methods available in 9.1 are available at the following locations:
- All bugs fixed up to Oasis montaj 9.1 (see https://my.geosoft.com/downloads)
Version 9.0 Beta :
This is a BETA release intended to support developers that link stand-alone programs and external DLL's with the GX Developer API. Oasis montaj 9.0 is a 64-bit application and will only work with 64-bit DLLs. Any GX programs that use external DLLs AND need to run inside Oasis montaj 9.0 will need to have the external DLLs recompiled as 64-bit DLLs.
See GX Developer 9.0 BETA for more information.
Version 8.5.1 :
Note that version 8.5.1 is the first released version of GX Developer for Geosoft version 8.5 applications.
Documentation: GX Developer 8.5
- See http://docs.geosoft.com/gxdev/8.5/dotnet/GXNet/html/version-history.htm for a list of new API methods added in 8.5.0. Note that 8.5.1 is a maintenance release that has no new API methods. Notable in the 8.5 is the DBREAD class, which support blocked reading and writing for very large lines.
- Geosoft ID authentication improvements. These important changes support user security and future rights management through Geosoft ID. Note that in the next major release of Geosoft platforms the Geosoft license key will be replaced by rights managed using Geosoft ID. This removes the need for users to park license keys to transfer rights.
- All bugs included in Oasis montaj 8.5 and 8.5.1 (see https://my.geosoft.com/downloads/update/832)
Version 8.4.1 :
- Addressed issue with GXC.exe failing to report compilation errors
Version 8.4 :
- Python 3.4 support, 32-bit and 64-bit
- Reference documentation (this document) improved and moved on-line
- Added support for Geosoft ID and user authentication via Geosoft Connect
- Added support for Geosurface and Geostring
