gch is an ASIS-based tool built on top of the ASIS implementation for GNAT (ASIS-for-GNAT). As it is implemented now, gch uses some GNAT-specific features and therefore it is not 100% portable.
gch does not have any platform-specific features and it works with any GNAT porting.
When you extract the content of this archive into a directory, you obtain the following directory structure:
gch is an ASIS application, so to create this executable, you need ASIS-for-GNAT installed on your machine. The current version of gch has been developed and tested with the public version of the GNAT/ASIS technology 3.11p.
After creating the executable for gch, you may put it and the gch configuration files gch.ini and rules.ini somewhere on your path.
Supposing that ASIS-for-GNAT is installed as an Ada library and that you are in the directory where gch sources are unpacked, to create the executable for gch (named also gch), you should call gnatmake like this:
gnatmake -o gch gch-driver.adb -largs -lasis -lgnat
Under Windows 95/98/NT you can use also the file COMPILE.bat to create the executable for gch, the file CHECK_ALL.bat to check all files of the Tests sub-directory, the file CLEAN.bat to remove all tree and ali files from the sub-directory, and files TEST-*.bat to run some simple tests.
The file named gnat_tests.txt (155K) contains an output of checking all Ada sources from gnat_3.11p-src by the gch (using Gnat_Mode, Delete_Tree_Mode, Hide_Rejected_Files, Show_Global_Statistics, and not Verbose_Mode of diagnostics). It takes 15 min on Pentium II 260 MHz, 64MB.
See ASIS-for-GNAT documentation for more details concerning using the ASIS implementation for GNAT and creating executables for ASIS applications.
See the gch Users' Guide (file gch_ug.txt) included in the gch distribution for more details about how to use gch.
