[SOLVED] make: *** [.obj/matrix.o] Error

ifonly · 02-24-2011, 09:07 PM

Greetings all,

I am a newbie, and this is my first post here.

I am trying to install a program and it spews out an error about the .obj/matrix.o file.

The output is quoted here:

Code:

To be more specific, here lists more information:
OS: RHEL 6 /64bit
Kernel: 2.6.32-71.el6.x86_64
Qt: Qt4
The program I was trying to install is a robot simulator which performs lots of matrix manipulation and linear system solving. I followed every step in the installation guide, except for this one:

Quote:

On Ubuntu, all you need to do is install the following packages from the package manager:
libblas-dev
liblapack-dev

As shown above, I am using RHEL 6, which has different libraries with Ubuntu. I tried "yum search" and installed these libraries instead:
lapack.x86_64 : Numerical linear algebra package libraries
blas.x86_64 : The Basic Linear Algebra Subprograms library

For the last step, I typed make and got those errors. I searched online but found no related topics. Hope someone here would have some idea and give me some suggestions.

Your problem seems to be around this:

Code:

include/math/matrix.h:114: error: ‘stderr’ was not declared in this scope

Take a look at this header file "matrix.h" and try to find out how is it declaring "stderr", maybe they didn't include <iostream>

Code:

#include <iostream>

Thanks for pointing it out, isalab.

I didn't notice there was an error on that line...

I checked the file "matrix.h", it already included <iostream>. But I found that another header should be included:

#include <cstdio> (I guess it is because of the gcc version)

Then I run make, those errors were gone. It showed me some other errors but then I eventually got all those fixed. The program is running now.

Thanks again for your help,

Regards,
vincent

So I'm actually trying to install the same program and got the same error (that's what led me to this page). I fixed the initial error but now I'm getting this one.

Code:

ui/mainWindow.cpp:38: fatal error: QAssistantClient: No such file or directory
compilation terminated.

Did you encounter this error? If so, how did you fix it?

apt-cache search QAssistantClient
sudo apt-get install libqt4-dev

EDIT : Sorry, for RHEL6 it is : yum provides */QAssistantClient

# yum install qt-devel

..

shy8675 · 06-15-2011, 10:04 AM

Code:

libqt4-dev is already the newest version.

I read somewhere on the Internet that the newest versions of Qt don't use QAssistant client anymore. Could that be the problem?

The weird thing is that I was able to get this program up and running last week on a different computer (same hardware, same OS, using the same procedure).

knudfl · 06-15-2011, 10:31 AM

# yum provides */QAssistantClient

1:qt-devel-4.6.2-16.el6.x86_64 : Development files for the Qt toolkit
Repo : sl
Matched from:
Filename : /usr/include/QtAssistant/QAssistantClient

So the file is present, not as /usr/include/QAssistantClient,
but /usr/include/QtAssistant/QAssistantClient

Which application is it about ? graspit-2.2_prerelease_2 ? ?

..

shy8675 · 06-15-2011, 10:40 AM

I downloaded it from this website (the Linux version). http://www.cs.columbia.edu/~cmatei/g...oad/getit.html So I guess it's graspit-2.1.0. I feel like there was something I did in the installation of the prerequisite programs even though all I did was follow the instructions in the manual.

(Also, sorry to ifonly for hijacking your thread.)

knudfl · 06-15-2011, 12:35 PM

Yes, I can see now, that it is version 2.1.0 :

Quote:

[root@robot007 Graspit]#

graspit-2.2_prerelease_2.tar.gz is here ( sourceforge )
http://switch.dl.sourceforge.net/pro...lease_2.tar.gz
.. and may be easier to build on RHEL :

I made one workaround : cd /usr/include/
# ln -s Coin2/Inventor

Build requirements used :
Coin2-2.5.0-10.el6.x86_64.rpm Coin2-devel-2.5.0-10.el6.x86_64.rpm
SoQt-1.5.0-1.el6.x86_64.rpm SoQt-devel-1.5.0-1.el6.x86_64.rpm
( Created from the Fedora 14 SRC RPMS.)

..

knudfl · 06-15-2011, 02:49 PM

... And then Graspit-2-1-0 :
cd Graspit/qhull && make && cd ../ && qmake-qt4 && make CXX=g++34 : No errors.

And I really can't tell, how you could configure Graspit,
so the header 'QAssistantClient' wasn't found.

Did you set the environment variable QTDIR and PATH properly?
Graspit2.1.0 runs well on my RHEL6 x64, with Qt 4.6.2, SoQt 1.5.0, and Coin 2.5.0.
The QTDIR on my computer is /usr/lib64/qt4

shy8675 · 06-16-2011, 02:49 PM

Well, this is what I modified in my .bashrc file.

Code:

#things for GraspIt!
COINDIR=/usr/local/Coin
PATH=$PATH:$COINDIR/bin
LD_LIBRARY_PATH=$COINDIR/lib

QTDIR=/usr/share/qt4
#QTDIR=/usr/include/qt4
PATH=$PATH:$QTDIR/bin

I also set the GraspIt! directory appropriately.

I don't know if this would help, but this is what prints when I ask for the $PATH variable.

Code:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/Coin/bin:/usr/share/qt4//bin:/usr/local/Coin/bin:/usr/lib/qt4/bin:/usr/local/Coin/bin:/usr/share/qt4/bin:/usr/local/Coin/bin:/usr/include/qt4/bin

Which OS are you using?

ifonly · 06-17-2011, 07:03 AM

something wrong in your $PATH,

Quote:

/usr/share/qt4//bin

shy8675 · 06-17-2011, 10:23 AM

Huh, I didn't notice that. Thanks!

I fixed it but it's still giving me the same error, even when I did a make clean before compiling.

EDIT: Oh, also, the OS I'm using is Ubuntu 10.10.
