insight6.8

insight6.8

[Denis PILAT]

Hi Keith,

I saw you integrated Dave Murphy's MINGW patches, that's a good 
enhancement for us.

I've tried to build an insight 6.8 under windows XP host, but after the 
configure and a make without any problem, I get only gdb.exe.
Usually, the presence of additional package from gdb distribution (tcl, 
tk, libgui ..) is enought to build insight along with gdb.

Is there any changes in the way to build insight  ?

Thanks
Denis


P.S.I'm building within cygwin environment using (CFLAGS and CPPFLAGS 
set to ="-mno-cygwin")
I'm using "--build=i686-pc-cygwin --host=i686-mingw32"

Nothing of which I am aware. Perhaps I botched the patch?

I've tried this locally without success. Modules outside of gdb/insight 
keep failing unable to find alloca.h. Is there something else I can try? 
Is there a page on the web somewhere that describes building gdb on 
cygwin for mingw32 hosts?

If I can reproduce this here, I might be able to be of more help. [Note 
I said, "might"! :-)]

Hi Keith,

I put Dave in CC.

I successfully build gdb.exe and insight.exe using cygwin environment 
(with CPPFLAGS=CFLAGS="-mno-cygwin") but also using MSYS environment and 
gcc3.4.2.

1st problem:
   gdb.exe was built automatically, but to get insight.exe I had to do 
"make insight.exe" into the gdb subdir.

2nd problem:
For installation,  insight.exe was not installed after "make install" 
but only after "make install-gdbtk" done into the gdb subdir only.

3rd problem:
Then when running insight.exe I get the error message : "Interperter 
insight: unrocognized


I don't know why by some library are not linked when building 
insight.exe (libgui, tcl ...) , a problem in the configure may be but I 
cant find where (it works fine under linux host) ?

Any idea ?
Dave, how do you build on windows host to get a pure windows binary 
(without cygwin dll dependencies) ?

Unfortunately not.
If you have a recent cygwin environment  installed (with "Devel" 
package, including flex sub-package), you can run
export CPPFLAGS="-mno-cygwin"
export CFLAGS="-mno-cygwin"
export CC=gcc
export AR=ar
export WINDRES=windres
export MAKEINFO=makeinfo
/cygdrive/blablabla/insight-6.8/configure --host=i686-mingw32 
--target=i686-mingw32 --disable-nls --disable-werror
make


Hope it helps

My colleague Hector Soto found a patch:

gdb/configure.ac @ 1448

-   *-*-cygwin*)
+  *-*-cygwin* | *-*-mingw*)

After running autoconf in the GDB directory you can build as before.
(Or hack configure manually at line 23083.)

You can also specify --with-tclconfig=/your_build_dir/tcl/win
--with-tkconfig=/your_build_dir/tk/win at configure time, but that is
just working around the real issue that configdir is not initialized.

Keith: could you patch this at the appropriate places?

I get the same error (MSYS/MinGW with gcc-3.4.5). Do the warnings in
the logging below have something to do with it?
