# GLEW - The OpenGL Extension Wrangler Library
|
||||
# GLEW-cmake - nightly pre-generated snapshot with old unofficial cmake support
|
||||
|
||||
The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems, including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.
|
||||
[GLEW](https://github.com/nigels-com/glew) is upstream of this project.
|
||||
But *GLEW* repository does not contain generated sources. Only releases include generated sources.
|
||||
|
||||
|
||||
*GLEW-cmake* has generated sources based on the latest *GLEW*. Sources are generated nightly.
|
||||
If you need only the latest snapshot of *GLEW*, try the build system of *GLEW*. It is placed under the `build` directory. Official `CMakeLists.txt` is placed in `build/cmake`.
|
||||
Please check [README_glew.md](./README_glew.md) for using build system of *GLEW*.
|
||||
|
||||
http://glew.sourceforge.net/
|
||||
Also, *GLEW-cmake* has unofficial cmake support - It is created when the official CMake support of *GLEW* does not exist.
|
||||
You can see some CMake script examples in [`glew-cmake`](./glew-cmake/) directory. But, I **strongly** recommend using official CMakeLists of *GLEW*.

This project provide `libglew_static` and `libglew_shared` library targets and `glewinfo` and `visualinfo` executable targets.
|
||||
|
||||
## Table of Contents
|
||||
`libglew_static` provides a static library, and `libglew_shared` provides a shared library.

You can disable each library target by setting `glew-cmake_BUILD_SHARED` or `glew-cmake_BUILD_STATIC` falsy value (ex. `NO`, `FALSE`).
|
||||
|
||||
## Downloads
|
||||
If you need only libraries, Please set `ONLY_LIBS` to `ON`. Otherwise, cmake generates executable targets also.
|
||||
|
||||
Current release is [2.2.0](https://github.com/nigels-com/glew/releases/tag/glew-2.2.0).
|
||||
[(Change Log)](http://glew.sourceforge.net/log.html)
|
||||
You can get pkg-config fils by setting `PKG_CONFIG_REPRESENTATIVE_TARGET` to `libglew_static` or `libglew_shared`.
|
||||
|
||||
Sources available as
|
||||
[ZIP](https://github.com/nigels-com/glew/releases/download/glew-2.2.0/glew-2.2.0.zip) or
|
||||
[TGZ](https://github.com/nigels-com/glew/releases/download/glew-2.2.0/glew-2.2.0.tgz).
|
||||
Simply specify dependency of your target with `libglew_static` or `libglew_shared` by `target_link_libraries`.
|
||||
It will set the additional include directory & the libraries to link to your target.

### Recent snapshots
|
||||
|
||||
Snapshots may contain new features, bug-fixes or new OpenGL extensions ahead of tested, official releases.
|

|
||||
|
||||
## Build
|
||||
|
||||
It is highly recommended to build from a tgz or zip release snapshot.
|
||||
The code generation workflow is a complex brew of gnu make, perl and python, that works best on Linux or Mac.
|
||||
The code generation is known to work on Windows using [MSYS2](https://www.msys2.org/).
|
||||
For most end-users of GLEW the official releases are the best choice, with first class support.
|
||||
|
||||
### Linux and Mac
|
||||
|
||||
#### Using GNU Make
|
||||
|
||||
GNU make is the primary build system for GLEW, historically.
|
||||
It includes targets for building the sources and headers, for maintenance purposes.
|
||||
|
||||
##### Install build tools
|
||||
|
||||
Debian/Ubuntu/Mint: `$ sudo apt-get install build-essential libxmu-dev libxi-dev libgl-dev`
|
||||
|
||||
RedHat/CentOS/Fedora: `$ sudo yum install libXmu-devel libXi-devel libGL-devel`
|
||||
|
||||
FreeBSD: `# pkg install xorg lang/gcc git cmake gmake bash python perl5`
|
||||
|
||||
##### Build
|
||||
|
||||
$ make
|
||||
$ sudo make install
|
||||
$ make clean
|
||||
|
||||
Targets: `all, glew.lib (sub-targets: glew.lib.shared, glew.lib.static), glew.bin, clean, install, uninstall`
|
||||
|
||||
Variables: `SYSTEM=linux-clang, GLEW_DEST=/usr/local, STRIP=`
|
||||
|
||||
_Note: you may need to call `make` in the **auto** folder first_
|
||||
|
||||
##### Linux EGL
|
||||
|
||||
$ sudo apt install libegl1-mesa-dev
|
||||
$ make SYSTEM=linux-egl
|
||||
|
||||
##### Linux OSMesa
|
||||
|
||||
$ sudo apt install libosmesa-dev
|
||||
$ make SYSTEM=linux-osmesa
|
||||
|
||||
##### Linux mingw-w64
|
||||
|
||||
$ sudo apt install mingw-w64
|
||||
$ make SYSTEM=linux-mingw32
|
||||
$ make SYSTEM=linux-mingw64
|
||||
|
||||
#### Using cmake
|
||||
|
||||
The cmake build is mostly contributer maintained.
|
||||
Due to the multitude of use cases this is maintained on a _best effort_ basis.
|
||||
Pull requests are welcome.

|
||||
|
||||
## Code Generation
|
||||
|
||||
A Unix or Mac environment is needed for building GLEW from scratch to
|
||||
include new extensions, or customize the code generation. The extension
|
||||
data is regenerated from the top level source directory with:
|
||||
|
||||
make extensions
|
||||
|
||||
An alternative to generating the GLEW sources from scratch is to
|
||||
download a pre-generated (unsupported) snapshot:
|
||||
|
||||
https://sourceforge.net/projects/glew/files/glew/snapshots/
|
||||
|
||||
## Authors
|
||||
|
||||
GLEW is currently maintained by [Nigel Stewart](https://github.com/nigels-com)
|
||||
with bug fixes, new OpenGL extension support and new releases.
|
||||
|
||||
GLEW was developed by [Milan Ikits](http://www.cs.utah.edu/~ikits/)
|
||||
and [Marcelo Magallon](http://wwwvis.informatik.uni-stuttgart.de/~magallon/).
|
||||
Aaron Lefohn, Joe Kniss, and Chris Wyman were the first users and also
|
||||
assisted with the design and debugging process.
|
||||
|
||||
The acronym GLEW originates from Aaron Lefohn.
|
||||
Pasi Kärkkäinen identified and fixed several problems with
|
||||
GLX and SDL. Nate Robins created the `wglinfo` utility, to
|
||||
which modifications were made by Michael Wimmer.
|
||||
|
||||
## Contributions
|
||||
|
||||
GLEW welcomes community contributions. Typically these are co-ordinated
|
||||
via [Issues](https://github.com/nigels-com/glew/issues) or
|
||||
[Pull Requests](https://github.com/nigels-com/glew/pulls) in the
|
||||
GitHub web interface.
|
||||
|
||||
Be sure to mention platform and compiler toolchain details when filing
|
||||
a bug report. The output of `glewinfo` can be quite useful for discussion
|
||||
also.
|
||||
|
||||
Generally GLEW is usually released once a year, around the time of the Siggraph
|
||||
computer graphics conference. If you're not using the current release
|
||||
version of GLEW, be sure to check if the issue or bug is fixed there.
|
||||
|
||||

## glewinfo
|
||||
|
||||
`glewinfo` is a command-line tool useful for inspecting the capabilities of an
|
||||
OpenGL implementation and GLEW support for that. Please include `glewinfo.txt`
|
||||
with bug reports, as appropriate.

## Code Generation
|
||||
|
||||
A Unix or Mac environment is needed for building GLEW from scratch to
|
||||
include new extensions, or customize the code generation. The extension
|
||||
data is regenerated from the top level source directory with:
|
||||
|
||||
make extensions
|
||||
|
||||
An alternative to generating the GLEW sources from scratch is to
|
||||
download a pre-generated (unsupported) snapshot:
|
||||
|
||||
https://sourceforge.net/projects/glew/files/glew/snapshots/
|
||||
|
||||
## Authors
|
||||
|
||||
GLEW is currently maintained by [Nigel Stewart](https://github.com/nigels-com)
|
||||
with bug fixes, new OpenGL extension support and new releases.
|
||||
|
||||
GLEW was developed by [Milan Ikits](http://www.cs.utah.edu/~ikits/)
|
||||
and [Marcelo Magallon](http://wwwvis.informatik.uni-stuttgart.de/~magallon/).
|
||||
Aaron Lefohn, Joe Kniss, and Chris Wyman were the first users and also
|
||||
assisted with the design and debugging process.
|
||||
|
||||
The acronym GLEW originates from Aaron Lefohn.
|
||||
Pasi Kärkkäinen identified and fixed several problems with
|
||||
GLX and SDL. Nate Robins created the `wglinfo` utility, to
|
||||
which modifications were made by Michael Wimmer.
|
||||
|
||||
## Contributions
|
||||
|
||||
GLEW welcomes community contributions. Typically these are co-ordinated
|
||||
via [Issues](https://github.com/nigels-com/glew/issues) or
|
||||
[Pull Requests](https://github.com/nigels-com/glew/pulls) in the
|
||||
GitHub web interface.
|
||||
|
||||
Be sure to mention platform and compiler toolchain details when filing
|
||||
a bug report. The output of `glewinfo` can be quite useful for discussion
|
||||
also.
|
||||
|
||||
Generally GLEW is usually released once a year, around the time of the Siggraph
|
||||
computer graphics conference. If you're not using the current release
|
||||
version of GLEW, be sure to check if the issue or bug is fixed there.
