For the past few days I'm seeing this when building php on machines
where I build Postgres from cvs:
gcc -o conftest -g -O2 -L/usr/lib -Wl,-rpath,/usr/local/pgsql/lib
-L/usr/local/pgsql/lib conftest.c -lcrypt -lmm -lpspell -lpq -lmhash
-lmcrypt -lltdl -lldap -llber -lcrypt -lpam -lgmp -lfreetype -lpng -lz
-ljpeg -lz -ldb-4.0 -lgdbm -lcurl -lbz2 -lz -lssl -lcrypto -lresolv -lm
-ldl -lnsl -lcurl -lssl -lcrypto -ldl -lxml2 -lz -lm -lcrypt 1>&5
/usr/local/pgsql/lib/libpq.so: undefined reference to `is_absolute_path'
collect2: ld returned 1 exit status
It looks like is_absolute_path is function in a new file src/port/path.c.
I also see:
ar crs libpq.a fe-auth.o fe-connect.o fe-exec.o fe-misc.o fe-print.o
fe-lobj.o pqexpbuffer.o dllist.o pqsignal.o fe-secure.o wchar.o
encnames.o ip.o md5.o
ranlib libpq.a
Doesn't path.o need to be linked in similar to the other backend files?
