It sort of looks like you are trying to compile a Windows distro of the source code on a 'Nix box to me... -- Regards, Gregory P.

I have been compiling from source for contrib files and c-functions since version 7.3 without problem. I downloaded postgresql-base-8.2.1.tar.gz and unzipped it into the PostgreSQL Program Files directory. I ran configure without problem, but when I run make I get the following error: $ make make -C doc all make[1]: Entering directory `/c/Program Files/PostgreSQL/postgresql-8.2.1/doc' make[1]: Nothing to be done for `all'. make[1]: Leaving directory `/c/Program Files/PostgreSQL/postgresql-8.2.1/doc' make -C src all make[1]: Entering directory `/c/Program Files/PostgreSQL/postgresql-8.2.1/src' make -C port all make[2]: Entering directory `/c/Program Files/PostgreSQL/postgresql-8.2.1/src/port' gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -fno-strict-aliasing -I../../src/port -DFRONTEND -I../../src/include - I./src/include/port/win32 -DEXEC_BACKEND -c -o crypt.o crypt.c In file included from ../../src/include/c.h:826, from crypt.c:44: ../../src/include/port.h:17:19: netdb.h: No such file or directory ../../src/include/port.h:18:17: pwd.h: No such file or directory ../../src/include/port.h:333:24: netinet/in.h: No such file or directory ../../src/include/port.h:334:23: arpa/inet.h: No such file or directory make[2]: *** [crypt.o] Error 1 make[2]: Leaving directory `/c/Program Files/PostgreSQL/postgresql-8.2.1/src/port' make[1]: *** [all] Error 2 make[1]: Leaving directory `/c/Program Files/PostgreSQL/postgresql-8.2.1/src' make: *** [all] Error 2 The files that cannot be found are in the source tree. Ths has me stumped. Am I forgetting something obvious?? Thanks, George
