1 # GalilTools {#gcl}
2
3 To provide maximum compatibility, gclib ships with an open source wrapper implementation of the GCL
4 (GalilTools Communication Library). Users wanting to upgrade to gclib that have source built on Galil.h
5 can use this wrapper to minimize source changes. This wrapper is also indicated for users that want the
6 same function calls as Galil.h, but don't want the usage of <a href="http://qt-project.org/">QT</a>
7 as in galil1.dll.
8
9 **This wrapper is intended for existing applications already using the library distributed with GalilTools (galil1.dll)
10 or the previous *STL* library (galil2.dll). New applications should be written with gclib.**

18 ###Compile galil2.dll with MSVC 2013
19 The following instructions were performed on *Visual Studio Professional 2013* and can be extended to other Visual Studio versions.
20 For brevity, the instructions assume the default installation location of **C:\\Program Files (x86)\\Galil\\gclib** and a build type of **x86 (win32)**.
21
22 ###Launch the compiler command prompt
23
24 * Open *VS2013 x86 Native Tools Command Prompt*.
25 * Navigate to a convenient, writable location, e.g. *C:\\temp*.
26
27 ###Set an environment variable for the base path
28
29 C:\temp>set base=C:\Program Files (x86)\Galil\gclib
30
31 ###Compile the source code
32 **Note the quotes.**
33
34 C:\temp>cl -c "%base%\source\wrappers\gcl\*.cpp" -I "%base%\include" -EHsc -MD
35
36 ###Link the source code
37 **Note the quotes.**
38
39 C:\temp>link /DLL gcl_datarecord.obj gcl_galil.obj "%base%\lib\dynamic\x86\gclib.lib" "%base%\lib\dynamic\x86\gclibo.lib" /OUT:galil2.dll
40
41 The output files *galil2.dll* and *galil2.lib* can now be used in a project using the GCL.
42
43 ###Test
44 Help the loader find the right dlls.
45
46 C:\temp>set PATH=%PATH%;%BASE%\dll\x86
47
48 Link the simple example.
49
50 C:\temp>link gcl_simple.obj "%base%\lib\dynamic\x86\gclib.lib" "%base%\lib\dynamic\x86\gclibo.lib" galil2.lib /OUT:simple.exe
51
52 Run the example.
