I am experiencing the following
problem with g77

$ g77 -O4 -lstdc++ cwrapper.o toyprob.o algencanma.o algencan.o -o

algencanma

/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
$

Any ideas?

 If you installed a compat g77 package, you may also need to install
a
compat runtime library as well, but you would have thought that
would be
a

part of the package dependencies.  do you have any of:

libstdc++-4.1.2-33
compat-libstdc++-296-2.96-139
compat-libstdc++-33-3.2.3-62

 installed?  These are installed on my F8 server.

Thanks, Kevin. I have

# rpm -q libstdc++
libstdc++-4.1.2-33
#

but

# yum install compat-libstdc++
Plugin "gpgcheck" uses deprecated constant TYPE_INTERFACE.
Please use TYPE_INTERACTIVE instead.

Any further ideas?

 Sorry, that package names are:

 compat-libstdc++-296
 compat-libstdc++-33

 The rest of the names were version numbers.  Try:

       yum install compat-libstdc++-33

 or

       yum install compat-libstdc++-296

 which one you need depends on which library g77 is generating code
for....
Thanks again, Kevin. Now with

$ rpm -q compat-libstdc++-296
compat-libstdc++-296-2.96-139
$ rpm -q compat-libstdc++-33
compat-libstdc++-33-3.2.3-62
$ rpm -q libstdc++
libstdc++-4.1.2-33
$

The reported problem persists:

$ g77 -O4 -lstdc++ cwrapper.o toyprob.o algencanma.o algencan.o -o
algencanma
/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
$

Any further ideas?

 The error returned by ld indicates that it wants to load the library file
for stdc++.  It should be contained within your standard library search
path.  Do you have libstdc++-devel installed?  It contains the library
archive files that ld needs to load (sorry about the mis-direction earlier).
It should contain:

/usr/lib/gcc/i386-redhat-linux/4.1.2/libstdc++.a
/usr/lib/gcc/i386-redhat-linux/4.1.2/libstdc++.so
/usr/lib/gcc/i386-redhat-linux/4.1.2/libsupc++.a

 I think these are the files ld needs to find.

Yes, I do have libstdc++-devel installed. And furthermore,

# locate libstdc++.a
/usr/lib/gcc/i386-redhat-linux/4.1.2/libstdc++.a
# locate libstdc++.so
/opt/Adobe/Reader8/Reader/intellinux/lib/libstdc++.so.6
/opt/Adobe/Reader8/Reader/intellinux/lib/libstdc++.so.6.0.7
/opt/google/desktop/lib/libstdc++.so.6
/usr/lib/libstdc++.so.5
/usr/lib/libstdc++.so.5.0.7
/usr/lib/libstdc++.so.6
/usr/lib/libstdc++.so.6.0.8
/usr/lib/gcc/i386-redhat-linux/4.1.2/libstdc++.so
/usr/lib/vmware/lib/libstdc++.so.5
/usr/lib/vmware/lib/libstdc++.so.5/libstdc++.so.5
# locate libsupc++.a
/usr/lib/gcc/i386-redhat-linux/4.1.2/libsupc++.a
#

Grumble, let me go and play for a bit and see if I can figure it out.
I'll install g77 here and see if I can compile/load a couple of small 
programs.   Back in a few....
