hi ALL

i have SUSE linux 10.0 system , i am trying to install MCTDH package ( scientific software) on it.

initially i had this error message-

g77: installation problem, cannot exec cc1, no such file or directory.

though cc1 is located at -

/usr/lib64/gcc/x86_64-suse-linux/4.0.2/cc1

other dir info-

/usr/bin/gcc
/usr/bin/g77
/usr/bin/f77

therefore i tried symbolic link in /usr/bin using command --
ln -s /usr/lib64/gcc/x86_64-suse-linux/4.0.2/cc1

after this i tried reinstall and compile the MCTDH program
i get this error message:

g77 -O2 -malign-double -ffast-math -funroll-loops -fomit-frame-pointer -msse2 -mfpmath=sse -m32 -I/home/jay/mctdh83.10/CompDir22795 -I/home/jay/mctdh83.10/source/include -c /home/jay/mctdh83.10/source/lib/utilities/platform.F
cc1: error: too many filenames given. Type cc1 --help for usage

opinions greatly appreciated and thanks in advance.

usually, cc1 is hiding behind gcc or whatever. So, rather than making symbolic link to it, try to streight out broken tree sounds better. In your case, gcc.

pardon, i did not understand, could you please explain in detail. thanks

Usually, user does not type "cc1", instead "gcc" or whatever. in other words, cc1 is backend of gcc or whatever.

I think, in your situation, the link from gcc to cc1 is broken. so that, tweaking path can tinker your situation, but not radical remedy.
