update to insight?

update to insight?

[Brian Phillips]

Hi - 

Are there any plans to continue updating 'insight'?

I can't get it to compile on Arch linux, i686, but have followed
directions from Arch AUR and the README, as well as instructions from
the FAQ.

It would be great to have a source that will compile with gcc >= 4.7.x.
As a new linux user, I don't know how to install / use gcc 4.2 alongside
4.7 on my system - and if I understand correctly, from comments found
online, 4.2 is required for compiling?  (I tried --disable-werror in
the ../src/configure command, but that didn't work).

I always get this error.
linux-nat.h:63:18: error: field ‘siginfo’ has incomplete type
make[2]: *** [i386-linux-nat.o] Error 1

If you would like more information from me, I'm happy to provide what I
can - just tell me what to do! :)

Kind Regards,
Brian Phillips

Insight is largely in maintenance mode. I still use it daily, and I will 
continue to do whatever I need to do to keep it working.

I build on Fedora 15, 17, Ubuntu 12.10, and Windows/MinGW fairly 
regularly. Fedora 17 comes with GCC 4.7.2, and I have no problems 
building for x86_64.

First things first. What is your configure triple? Can you configure and 
build gdb without Insight? What version of insight are you trying to build?

FWIW, I use CVS HEAD. I've never used a release, and I haven't made one 
in years. Now that things are starting to settle down around me, I am 
hoping to commit a few important patches for x86_64 and MinGW and make a 
new release. 6.8 is (obviously) ancient.

I've never tried Arch linux, but I'll try installing it into a VM...

this is so sad. it's a great product, I really wish someone in the
community would find the time to give it some love...

Please bear with me - in the past, I've dabbled with C and assembly, but
that was long ago, and I never really had to mess with configuring much
(it was a hobby).  But now, I want to put more effort into learning
assembly (still as a hobby, though).

I don't know what you mean by 'configure triple'.  I'm using a PKGBUILD
at https://aur.archlinux.org/packages/insight/ - you can view the
PKGBUILD from the web page, if you like.  If you look there, you might
also look at the comments at the bottom of the page, as well as this
thread, started by me in the forums:
https://bbs.archlinux.org/viewtopic.php?id=157819

AFAICT, There seems to be a bug in gcc-4.7.2 with a "struct siginfo"
that should be "struct siginfo_t", per this page:
http://sourceware.org/ml/libc-alpha/2012-03/msg00414.html

At any rate, other users get stuck with errors like this:
"/home/briphi/builds/gcc46/src/gcc-4.6.3/libgcc/../gcc/config/i386/linux-unwind.h: In function ‘x86_fallback_frame_state’:
/home/briphi/builds/gcc46/src/gcc-4.6.3/libgcc/../gcc/config/i386/linux-unwind.h:138:17: error: field ‘info’ has incomplete type
make[3]: *** [unwind-dw2.o] Error 1"

This applies to me in trying to build older versions of gcc (the snippet
above applies to building gcc-4.6.3) and the same applies to configuring
'insight'

With my limited knowledge and in using the PKGBUILD at
aur.archlinux.org, I'm pretty much stuck to using the source provided in
that script, which is 6.8.1a from sourceware.org.  I've tried to monkey
with the source line here, adjusting the first md5sum as needed, but
didn't get any where, due to the linux-unwind.h error above.

I have a dual-boot system with Ubuntu 12.10. Would you mind explaining
what I should do to build from source on Ubuntu?  So far, I've tried
uncompressing the source, and compiling from an alternate directory
using just "../src/configure", but that gave me the following errors:

config.status: creating po/Makefile.in
config.status: executing depfiles commands
config.status: executing libtool commands
config.status: executing default-1 commands

make[2]: Leaving directory `/home/brian/builds/insight/bfd'
make[1]: *** [all-bfd] Error 2
make[1]: Leaving directory `/home/brian/builds/insight'
make: *** [all] Error 2

Here is my gcc --version output from ubuntu:

brian@ubuntumachine:~/builds/insight$ gcc --version
gcc (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2

Many thanks for the reply and being willing to help!

And regarding building gbd, will I be okay doing this in a /home/user
directory?  I don't want to screw up my Ubuntu (or Arch) install, so I'm
a bit hesitant.

Kind regards,
Brian

No problem -- I haven't actively looked at assembly much in the last 
decade, either. All that Java got in the way. [I worked on Eclipse for 
several years. After that, I wrote JDWP/JVMTI implementations for 
gcj/gij and classpath.]

The configure triple is what gdb displays when you type "show version". 
This is what you pass to configure using the --host, --target, --build 
arguments. [If you don't specify anything, the build uses config.guess 
to "guess" --build=--target=--host.

For example, on my Fedora box, my configure triple is 
"x86_64-unknown-linux-gnu" (as reported by src/config.guess). What does 
config.guess return for you?

Hmmm... Where are these errors occurring? I don't even see these files 
in the build -- not in bfd, gdb, or insight.

There's not enough context here. I don't see the actual error. In any 
case, you should be able to build on Ubuntu -- that is one of the test 
platforms that I test.

Caveat: When I say you *should*, unfortunately, I stretch the truth a 
tiny bit. You should be able to checkout CVS HEAD insight and build that 
without problems (I have done that here). What you cannot do (without 
patches from me) is build insight without using the Tcl, Tk, Itcl, and 
Iwidgets from the repository (which is Tcl/Tk 8.4) *and* a 64-bit OS.

[WARNING: The default fonts for Insight with repository tcl et al are 
HORRIBLE. Click Preferences->Global... and change them! "clean" looks 
good to me.]

I have patches to make this work using your system Tcl, Tk, Itcl, but I 
haven't found Itk and Iwidgets in anywhere. [Itcl is included with Tcl, 
but Itk is not included with Tk.] So for now, use the repository Tcl, 
Tk, Itcl/Itk/Iwidgets. There are a bunch of warnings, but those can be 
ignored AFAIK.

If you want python support (recommended, especially for C++ 
pretty-printers), you must install the python2 package. Otherwise, 
base-devel contained pretty much everything I needed to build gdb/insight.

No problems. Just give configure a "--prefix" option and it will install 
to that location, e.g., --prefix=/home/me/insight-built will install 
everything to /home/me/insight-built without messing with your system 
directories.
