Hi all, I'm a computer-challenged physics student using Scientific Linux 6.2 through a virtual machine (on my Windows laptop), and since it was installed for me by others I don't really know what's on it (yes, I was stupid). I'm trying to install the software on this page: http://laplace.physics.ubc.ca/People/matt/rnpletal.html

When I follow the instructions, installation appears to fail because there is no working C compiler. I tried to install gcc, which I thought would include a C compiler, but configuration also seemed to fail because it couldn't find a C compiler, rather like opening a box which holds its own key... Is it possible that the compiler is there on the system but I don't know where it is? If so, how could I find it, and if not where do I get a compiler? I'm probably being really really stupid, but I would really appreciate some help. Thanks!

Better have a separate scientific linux install.

#su
#yum install gcc xforms* etc

GCC as a standalone package will not work.

# yum install gcc-c++ xforms
.. will also install packages to make gcc a full functional compiler.

'xforms' is in the rpmforge.repo

.

Thanks amani and knudfl, I was able to get the C compiler working that way. However, I still don't have a Fortan compiler, which I thought was supposed to come with gcc? Also, xforms was not recognized as a package, so I don't know how to get its dependencies. How can I find what packages are available?

'xforms' : Add the rpmforge.repo ( Temporarily )
http://repoforge.org/use/

Or install the rpm package : http://pkgs.repoforge.org/xforms/
# yum localinstall --nogpgcheck xforms-1.0.91-1.el6.rf.<arch>.rpm

32bits http://pkgs.repoforge.org/xforms/xfo...l6.rf.i686.rpm
64bits http://pkgs.repoforge.org/xforms/xfo....rf.x86_64.rpm
.... And : xforms-devel-1.0.91-1.el6.rf.<arch>.rpm is required too.
Note : No dependencies would usually be required for xforms / xforms-devel.


Fortran : # yum install gcc-gfortran
The old g77 : # yum install compat-gcc-34-g77

Finding a package name : yum search <name> ( or part of name.)
Like : yum search fortran

P.S. : 'rnpletal' installs to Scientific Linux SL6.x with no errors.

also install yumex ... for the GUI way

Thanks a lot knudfl, that was really helpful. However, RNPL didn't install correctly for me, I think because it couldn't find the bbhutil.h library. I'm not sure what that refers to? This was also a problem when I tried to install xvs. Also, I need version 6.2 of the jpeg libraries and headers. I have the latest version, but only the earlier version is compatible with what I'm trying to install. How do I find and download older versions? Sorry about all the stupid questions...

The install command(s) example : 1) su
2) cd rpnletal/ && ./Install.gnu /usr/local
.... ( The test install, ref.post #5 : xforms-devel was installed.
But none of mpeg_encode-1.5c, xvs, DV were installed.)


The header "bbhutil.h" ( Not a library ) is located in :
rnpletal/rnpl/src/bbhutil.h

Finding files : The find command ...
cd rpnletal/ && find . -name "bbhutil.h"

P.S. : About xvs : Please read the file README, line 47.

.

All parts of "rpnletal/" should be compiled from the top directory.
Compiling a single library / application : Edit the script "PACKAGES.sh.


Example compiling / installing "rpnletal/rnpl/" only :

0) cd rpnletal/
1) cp PACKAGES.sh PACKAGES.sh-backup.txt
2) ... Edit 'PACKAGES.sh' to :
3) ./Install.gnu <destination>/

.

# 7
Which application / library is requiring "jpeg-6.2" ? ?



'xvs' prerequisites :
1) A full install of "rnpletal" to /usr/local/.
2) # yum install \
libXpm-devel libXmu-devel compat-gcc-34-g77 compat-libf2c-34 \
mesa-libGL-devel mesa-libGLU-devel libjpeg-devel
3) cd /usr/lib/ ; # ln -s libg2c.so.0.0.0 libg2c.so

$ cd xvs/ && ./configure && make : No errors.

Thanks again, knudfl. I thought you would be sick of answering my questions by now. You were right that I didn't need that specific version of the JPEG headers and libraries. RNPL was fome after I installed the parser-generator bison, and I think xvs and the mpeg_encode installed after that. However, I'm still having problems with DV. It seems to work for a while, but eventually there's a series of lines like this:

ctoirang.f.text+0x534): undefined reference to `_gfortran_string_index'

with string index replaced with other terms including compare_string, st_read, etc. After that, make error 1 appears several times and ultimately installation fails. What could be causing this?

# 11.

I worked on DV too : No luck.
The errors "undefined reference to `_gfortran_string_index' " etc.
can be avoided by not using gfortran : # yum remove gfortran
# yum install compat-gcc-34-g77 : /usr/bin/g77 (f77) will be used.
... But then ( starting from scratch with a new unpacked DV ),
some other errors will appear.
