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.
Loading "gpgcheck" plugin
Setting up Install Process
Parsing package install arguments
No package compat-libstdc++ available.
Nothing to do
#
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....
Thanks a lot, Kevin!
I wrote a quick and dirty f77 program:
INTEGER I
I = 5
STOP
END
and compiled it. It runs with the default libraries:
f77 -c foo.f -o foo.o
f77 foo.o -o foo
./foo
but if I try and load it with -lstdc++:
f77 foo.o -lstdc++ -o foo
I get:
/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
so, I agree with you. Are you using anything from the stdc++ library?
Can you remove it from your link command?
Paul
