Thanks a lot.
It works:
gcc -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -I../../../src/interfaces/libpq -I../../../src/include
-Wl,-rpath,/local/scratch-1/ww220/postgresql-7.1.3/lib -L/homes/ww220/myspace/postgresql-7.1.3/lib testlibpq.c -o
testlibpq-lpq
testlibpq.c: In function `exit_nicely':
testlibpq.c:14: warning: implicit declaration of function `exit'
I am a total newbie to almost everything. I put
export PATH=/local/scratch-1/ww220/myspace/postgresql-7.1.3/lib:$PATH
in .bash_profile and did ". .bash_profile". Is that different from putting
-L switch in gcc command?
