[gps-devel] Re: Builindg GPS on windows 2000...

[Chris Douty]

Hi Stephane,

Sorry for taking so long to get back to you.  I hadn't even attempted  
building GPS on Windows for quite a while, but just did so last night.

I am afraid that I don't have all of the answers in an easy form  
right now because my development environment is very hacked  
together.  The particular problem you are seeing below is from a  
syntax change in the C pre-processor or possibly a broken, untested  
feature in MinGW's gcc port.  Cygwin is not necessary, but it might  
be easier.

Deep within GPS's maze of makefiles, you will find "gps/builder/src/ 
Makefile.generic".  It defines the real commands used to compile C  
sources, and how to maintain dependencies.  The command echoed to the  
screen is not the actual compilation command.  I don't know why they  
(AdaCore) chose to complicate this like that.  On about line 298 you  
should find the definition of DEP_CFLAGS.  Change it to read:

DEP_CFLAGS = -MD -MF $(OBJ_DIR)/$(*F).pp

You will encounter other problems, but I am hesitant to say exactly  
what.  One this that is likely on Windows is the system bitching that  
it can not recompile a-textio.adb once it finally starts building Ada  
files.  This is due to a timestamp mismatch between gnat_src/s- 
crtl.ads and the compiler's internal library.  I "fixed" that by  
using touch -r to copy the timestamps from the adalib copy to the new  
copy.  I also had to hack about with the db library included with  
source navigator.  There was a configuration problem where Arno's fix  
for Windows undefined types broke with later version of MinGW.  I  
also had to remove "-fwritable-strings" from the tcl8.1 Makefile  
because my compiler simply does not support it.

Here's my environment:
Win XP SP2
mingw-runtime 3.7
w32api 3.2
bbinutils 2.15.94
MSYS 1.0.10
msysDtk 1.0.1

gcc 4.0.1 (prerelease 20050608) hacked to build.  This required a SEH  
patch of an origin I don't recall.

GtkAda from CVS -rgps-3_0-branch  updated 20050630
XmlAda from CVS HEAD
gps    from CVS  -rgps-3_0-branch  updated 20050630
gcc/ada source from mainline last updated 20050516 I think.  Probably  
should have updated these.

Gtk/glib from http://www.gimp.org/win32/
I didn't want to try building these huge number of dependencies  
without nice tools like Darwin ports or rpm.

If you have a choice, stick with Gtk 2.4.x for a while.  I used 2.6.8  
and had to edit a bunch of bindings on Windows.  I'm not sure that I  
found all of them, because apparently the symbols aren't resolved  
until an application tries to link with them.  I should audit the Gtk/ 
Glib headers for all the places where they decided to rename  
functions on windows via #define.  For example "gdk_new_from_file"  
becomes "gdk_new_from_file_utf8" on Windows.

In any case I did get the thing to build be sticking at it.  So far  
most things seem to work except that the "Emacs" theme is totally  
hosed, and building C++ projects adds an unsupported "-d" option to  
gprmake.  If I am brave/bored I will try GPS mainline, although I'll  
probably try working on Macc OS X 10.4 first.

Good luck,
     Chris
