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