[Plplot-general] fortran examples on openSUSE 11.2 with gfortran-4.4

[Joachim G. <joa...@ip...>]

Hi,
I have troubles building the fortran examples on my linux system
(openSUSE 11.2, x86_64, gcc (SUSE Linux) 4.4.2 [gcc-4_4-branch revision 
155802])
for plplot version 5.9.5. Everything works fine with building the examples
up to the point where x01f should be linked. There I get:
Linking CXX executable x01f
cd /home/geiger/build_dir/plplot-5.9.5_gfortran/examples/f77 && 
/usr/bin/cmake -E cmake_link_script CMakeFiles/x01f.dir/link.txt --verbose=1

function `_start':
/usr/src/packages/BUILD/glibc-2.10.1/csu/../sysdeps/x86_64/elf/start.S:109: 
undefined reference to `main'
CMakeFiles/x01f.dir/x01f.f.o: In function `MAIN__':
x01f.f:(.text+0x16): undefined reference to `_gfortran_set_options'
x01f.f:(.text+0x88): undefined reference to `_gfortran_st_write'
...

The obvious point I noted is that the linking is done with c++ and not
with gfortran. Entering the folder CMakefiles/x01f.dir and executing
the link-command with gfortran instead of c++ gives a nice working 
executable.
Any idea where things could have went wrong? Or has anyone encountered the
problem before?
Best regards,
Joachim
