configtool for linux building problems.

David Fernandez
Hi there,

This is probably a deja-vu, as I think I run into this the last time I
try it some time ago...

I have wxGTK-devel 2.8.12 from my Fedora 15 distribution...

I get the following output:

Sure you know what is wrong, as I couldn't get a reasonable search set

Using the linked wxGTK-2.8.8 in the ecoscentric web site, the problem is:

$ su -c 'make -f

install WXDIR=/usr/local ECOSSRCDIR=/home/davidfc/ecos/host

The folder "gizmos" does not exist inside /usr/local/include/wx-2.8/wx/,
that leaves me quite confused :( When this problem gets solved,
something should definitely be put in the ecos.sourceware.org web about
it...

Re: configtool for linux building problems.

David Fernandez
As people is quite busy these days, I eventually find the answer myself:

The best ecos help page for configtool and host tools in general is
http://www.ecoscentric.com/devzone/configtool.shtml, the README.txt in
ecos/host/tools/configtool/standalone/wxwin gives a make recipe that is
less flexible then the one indicated in the web page.

1.- The link to wxGTK-2.8.8 sources in the above, or any other
wxGTK-2.8.x sources are ok, but require a few tricks. After configuring,
building, and installing, as indicated in the eCosCentric web page for
configtool, while in the wxGTK build folder (not the sources one) do:
    cd contrib/src/gizmos
    make
    sudo make install
This should get the gizmos library and headers installed, which do not
seem to install by default.

2.- Edit the makefile.gnu in ecos/host/tools/configtool/standalone, and
add to the line EXTRALDFLAGS, at the end, after leaving a space, -lX11

3.- Build configtool as indicated in
http://www.ecoscentric.com/devzone/configtool.shtml
    sudo make -f
<path-to>/ecos/host/tools/configtool/standalone/wxwin/makefile.gnu \
                        install WXDIR=<wxgtk-install-prefix>
ECOSSRCDIR=<path-to>/ecos/host \
                        INSTALLDIR=<configtool-install-prefix>
The makefile.gnu has the full possible options, but if your tcl is
properly installed, only the ones shown above will be necessary.

N.B. wxGTK-2.9 has either integrated gizmos into normal wxGTK source
folders, or moved part of it to "wxCode" (perhaps an additional package
to configure --with-wxcode, but not sure).

Hopefully I'll be able to find this the next time... Although it would
be good to update the ecos.sourceware.org pages with this info, perhaps
the eCosCentric ones too.

By the way, if John Dallaway, or any other maintainer for configtool
could confirm its maintenance status, and if what I've put above is the
best way to solve the configtool build problems, that would be great.

Cheers

That is what I do to install gizmos.

I have not found -lX11 to be necessary. The invocation of wx-config
within makefile.gnu should return all the flags necessary to link with
the X window system. Which Linux distro and version are you using? Can
you forward the link-time error you observe without this change
(including all the command-line arguments) please?

Just a word of warning.  If you use versions of wxGTK above 2.8.8,
including the 2.9.x series (although I have not tried the latest 2.9.3
yet), you will find that there are a few things which are broken within
the configtool. As far as I am aware, there has been no work within
anoncvs to move the configtool to newer wxGTK libraries and
unfortunately, as you mentioned, we have been too busy to contribute our
updates to the configtool for this and 64 bit support (we have local
unrelated customizations and MinGW native windows support).

We therefore recommend that you stick with wxGTK 2.8.8 until the
configtool is updated in anoncvs.

Hi John,

This is the "simplified" output:

c++ -o configtool <lots-of-files.o>  -LTCLDIR_use_system/lib -L/usr/local/lib
-l<other-libs>... -ltcl `/usr/local/bin/wx-config --libs std,gizmos`
/usr/bin/ld: /usr/local/lib/libwx_gtk2_core-2.8.a(corelib_utilsx11.o):
undefined reference to symbol 'XGetWindowAttributes'
/usr/bin/ld: note: 'XGetWindowAttributes' is defined in DSO
/usr/lib/libX11.so.6 so try adding it to the linker command line
/usr/lib/libX11.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [/<my-build -folder>] Error 1

I compiled this in Fedora14+wxGTK-2.8.12 and Fedora15+wxGTK-2.8.8, and I
get the same problem in both of them (both wxGTK were compiled from
sources and installed in /usr/local, I know that /usr/local/bin is in
the PATH, but my LD_LIBRARY_PATH is empty, as I rely in the config
scripts for wx and tcl).

If you want the full link command (two or three screens), let me know,
and I'll recompile.

Cheers

This is almost certainly due to recent Fedora builds of GNU ld using
different DSO-linking semanics. Ref:

  http://fedoraproject.org/wiki/Features/ChangeInImplicitDSOLinking

Specifying -lX11 explictly for Linux builds seems reasonable and should
be safe for other users.

I've attached a patch at:

  http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001613

Thank you for reporting this.

Hi all,

I have encoutered David's problem with "XGetWindowAttributes" but this is happening when using the "-lX11" flag. I am stuck at this point, don't know what to do.

Here is the error:

/usr/bin/ld: /home/scas/ecos-stuff/wxGTK-2.8.8/lib/libwx_gtk2_core-2.8.a(corelib_utilsx11.o): undefined reference to symbol 'XGetWindowAttributes'
/usr/bin/ld: note: 'XGetWindowAttributes' is defined in DSO /usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libX11.so so try adding it to the linker command line
/usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libX11.so: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

If anyone could give me a hint what to do, I would greatly appreciate it.

Best,
Stefan

Are you use the latest makefile.gnu file from CVS? Ref:

http://ecos.sourceware.org/cgi-bin/cvsweb.cgi/ecos/host/tools/configtool/standalone/wxwin/makefile.gnu.diff?r1=1.15&r2=1.16&cvsroot=ecos&f=h

Note that the ordering of libraries on the linker command line is important.

I hope this helps.

Hi John,

Yes I am using the latest makefile. Here's how it looks - http://pastebin.com/Yzfw2KTF

I feel like this is a linking problem... I've seen that others had problems with this kind of "i386-linux-gnu/libX11.so so try
> adding it to the linker command line ", but couldn't understand exactly the reason or how to fix it. And unfortunately I am not a Linux guru.
I am trying now to make it compile on Windows but it takes ages, it is so slow.

By any change, do you have any other ideas?

Thank you a lot for your time.

Best,
Stefan

Hi again,

I let my brain "cool" until tonight and gave it another try - I realized that I use LXDE so I removed the flag for lx11 from the makefile and it worked. Don't know if it has anything to do with it, but it worked. (like I said, I am not a linux guru)

Thanks John for your earlier reply.

Regards,
Stefan
