Molpro quantum chemistry package

Unresolved symbols

The molpro configure scripts should add all the necessary libraries in order to link correctly. If a library is missed then you will receive an error message for unresolved symbols. The general form is:

somefile.f:(.text+0xab): undefined reference to `some_symbol_'

You can add them in the LIBS="..." entry in CONFIG or alternatively at the start of the LAPACKLIB_*="..." entry. Common unresolved symbols are:

```
s_copy
```
You need to link in the gnu compability library. On SuSE add
```
-lg2c
```
and on RedHat add
```
-L /usr/lib/gcc-lib/i386-redhat-linux/3.2.2 -lg2c
```
where the directory is given by
```
gcc -print-libgcc-file-name
```
(without the libgcc.a on the end)
```
__kmpc_*
```
With the intel compiler you can add
```
-openmp
```
to the LINKFC="..." line in CONFIG. If you are using the mkl libraries then as an alternate solution you can add (in all places in CONFIG)
```
-lguide
```
just before
```
-lmkl_lapack
```
```
__pthread*
```
requires
```
-lpthread
```
