If you wish to use dynamic linking, you must use |
| 217 |
LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH |
| 218 |
or |
| 219 |
setenv LD_LIBRARY_PATH `pwd` |
| 220 |
before running make. |
| 221 |
|
| 222 |
If you are using shared libraries from /usr/local/lib |
| 223 |
for libdbm or libgdbm you may need to set |
| 224 |
LD_RUN_PATH=/usr/local/lib; export LD_RUN_PATH |
| 225 |
in order for Configure to compile the simple test program |
