-\r
-Freeglut is an open-source evolution of GLUT.\r
-Under Windows, one can use it with Cygwin.\r
-Easy? Yes, if one agrees to distribute "cygwin1.dll".\r
-Let us help freeglut gain its independence !\r
-m.à.j 10/7/2009: generation of a library for linking without the DLL.\r
-\r
-\r
-Recovery of the sources\r
-\r
- * Download the sources of version 2.6.0 which integrates recent changes.\r
- * For the moment, it is a RC (Release Candidate), but the final version\r
- should not delay.\r
- * The use of the 2.6 is preferable with the 2.4-stable branch because many\r
- bugs have been corrected.\r
- * You will find the sources on the site of Freeglut:\r
- o http://freeglut.sourceforge.net/\r
-\r
-\r
-Objectives and preparation\r
-Objectives\r
-\r
- * We will create a DLL related to Cygwin, and an independent static library\r
- * We will also create a dynamic library, allowing linking with the DLL.\r
-\r
-\r
-List of generated files\r
-\r
- * freeglut.dll: a traditional DLL for the dynamic linkage.\r
- * libfreeglut.a: the static library. The final program is autonomous (at\r
- least for OpenGL).\r
- * libfreeglutdll.a: the dynamic library. The final program needs\r
- freeglut.dll.\r
-\r
-\r
-Preparation\r
-\r
- * Extract the files from the freeglut archive.\r
- * Go in the directory src (located at the root of the Freeglut directory),\r
- and create a "Gl" sub-directory\r
- o In this sub-directory, copy the files of the directory "include/Gl"\r
-\r
- * Why is it necessary to create a "Gl" directory for compilation?\r
- o I needed it to simplify things during my tests.\r
- o If not you can create the repertories directly, and copy the files\r
- as indicated in the point installation (see below).\r
-\r
- * Do a little housekeeping in /lib:\r
- o Erase all the references to the glut, so as not to conflict with the\r
- linking.\r
- o This stage is optional, you can also choose to do the housekeeping\r
- only after a successful compilation of Freeglut.\r
- o In your enthusiasm to clean things up, be careful not to erase the\r
- library glu32.lib (not to be confused with glut32.lib).\r
-\r
-\r
-Compilation\r
-\r
- * Forget the "./configure, make, make install" triptych.\r
- o It does not go at all with Cygwin.\r
-\r
- * Here Makefile which will make the deal:\r
-\r
-#Makefile for Freeglut 2.6.0-rc and Cygwin\r
-#To place in the directory \93src\94\r

-\r
-Some remarks on the makefile\r
-\r
- * This makefile creates a DLL, a static library (a file, in other words) and\r
- the dynamic library which will allow the use of the DLL.\r
-\r
- * Do not try to strip the static library! You may not be able to compile\r
- applications with static library any more.\r
- o On the other hand, you can strip the final executable obtained after\r
- compiling your application.\r
-\r
- * I chose to call the DLL and the libraries by their "true names":\r
- freeglut.dll libfreeglutdll.a and libfreeglut.a.\r
- o Script configures recreated (for reasons of compatibility with the\r
- old GLUT library) glut.dll and libglut.a.\r
- o During the my tests, I had conflicts with an authentic "glut" which\r
- trailed in my "/lib". I decided to call the things by their name, in\r
- order to avoid confusions.\r
- o Nothing prevents you from renaming the DLL, if you need to use GLUT\r
- programs which you cannot recompile.\r
-\r
- * The dynamic library is generated starting from the DLL.\r
- o For reasons of brevity, I used awk. It generates the export file\r
- used by dlltool.\r
- o The only notable thing is the selection of the functions whose name\r
- starts with _glut, in order to avoid including in the dynamic\r
- library the functions that are not related to freeglut.\r
- o then, one uses dlltool in a very traditional way.\r
-\r
-Nm $ (libname) .dll | awk \93BEGIN {print \93EXPORTS\94} /T _glut/{sub (/^.*T _/,\94 \ T "); print}\94 > $ (libname) .def\r
-dlltool --dllname $ (libname) .dll --input-def $ (libname) .def --output-lib lib$ (libname) dll.a\r
-\r
-\r
-\r
-\r
-Installation\r
-\r
- * Copy libfreeglut.a, libfreeglutdll.a into the Cygwin directory /lib.\r
- * Copy freglut.dll in the system32 of Windows (this is practical, but not\r
- clean!).\r
- * Copy the files headers of Freeglut (/include/gl) into the Cygwin directory\r
- /usr/include/Gl.\r
- * Copy the files headers (always /include/gl) into /usr/include/mingw/Gl:\r
- this is used for compilations with the flag - mno-cygwin, which uses the\r
- includes in mingw.\r
- o You may need to erase the old GLUT include files if you installed it\r
- with Cygwin.\r
-\r
-\r
-Use of the library\r
-\r
- * We will test with the program shapes, found in progs/demonstrations/shapes\r
- o -mno-cygwin is used to force the use of Mingw without the large\r
- dependence cygwin1.dll.\r
- o -mwindows is only used to remove the horrible Shell window (very\r
- useful for the settling, on the other hand).\r
- o -L. (note the period after the "L"): I left libfreeglut.a,\r
- libfreeglutdll.a and freeglut.dll in the test directory, at the time \r
- of the tests.\r
-\r
-\r
-Compilation of the static freeglut library, without cygwin\r
-\r
- * All the simplicity lies in the define: -DFREEGLUT_STATIC\r
- o It serves to obtain good decoration of the function names in the\r
- imports of the lib Freeglut.\r
- o You can test without and use a hex editor to see the differences\r
- in the objects.\r
- * attention with the order of the libraries: -lfreeglut (static) must be\r
- before the declaration of the dynamic libraries.\r
-\r
- * gcc shapes.c -L. -lfreeglut -lopengl32 -lwinmm -lgdi32 -mno-cygwin -mwindows -DFREEGLUT_STATIC\r
-\r
-\r
-Compilation with DLL freeglut, without cygwin\r
-\r
- * For the define, see the notices above\r
- * The order of the libraries is no longer important.\r
-\r
- * gcc shapes.c -L. -lopengl32 -lwinmm -lgdi32 -lfreeglut -mno-cygwin -DFREEGLUT_STATIC\r
-\r
-\r
-Compilation with DLL freeglut, Cygwin\r
-\r
- * This example is given only for reference, the topic of this ticket being\r
- to get rid of Cygwin.\r
- o Let us say that can be used to make the point (and later).\r
-\r
- * gcc shapes.c -L. -lopengl32 -lwinmm -lgdi32 -lfreeglut\r
-\r
-\r
-\r
-Where are the dooooocs?\r
-\r
- * Freeglut is delivered with its documentation, more very up to date.\r
- o It seems that there is a problem with the original GLUT\r
- documentation. Not only it does not correspond completely to the\r
- operation of Freeglut, but moreover, its author (Mark Kilgard)\r
- copyrighted it. Its distribution is thus difficult.\r
-\r
- * Jocelyn Fréchot undertook a levelling of the docs for version 2.6.0. One can find them on his site for the moment:\r
- o http://jocelyn.frechot.free.fr/freeglut/\r
-\r
-\r
-Something survived\85\r
-\r
- * I also tested the recompiling of the demonstrations of the original lib\r
- GLUT (peace with its ashes).\r
