Very Computer

    our group at school has written an rpc application under Sun
Solaris. It compiles and works under Sun just fine.
Now we are trying to compile the program under Linux and get the
following error message during compilation:

gcc -ansi -g -D_GNU_SOURCE -c library_clnt.c
gcc -ansi -g -D_GNU_SOURCE -c library_xdr.c
gcc -ansi -pedantic -Wall -g -D_GNU_SOURCE -c client.c
gcc -ansi -pedantic -Wall -g -D_GNU_SOURCE -lnsl library_clnt.o
library_xdr.o client.o -o client
gcc -ansi -g -D_GNU_SOURCE -c library_svc.c
gcc -ansi -pedantic -Wall -g -D_GNU_SOURCE -c server.c
server.c:26: conflicting types for `book_search_1'
library.h:61: previous declaration of `book_search_1'
server.c:85: conflicting types for `enter_book_1'
library.h:64: previous declaration of `enter_book_1'
server.c:127: conflicting types for `delete_book_1'
library.h:67: previous declaration of `delete_book_1'
server.c:181: conflicting types for `get_book_1'
library.h:70: previous declaration of `get_book_1'
server.c:244: conflicting types for `unget_book_1'
library.h:73: previous declaration of `unget_book_1'
make: *** [server.o] Error 1

These are the options we are using in the Makefile

#  Compiler Optionen
CC = gcc -ansi -pedantic -Wall -g -D_GNU_SOURCE
# RPC Compiler Optionen
CC_RPC = gcc -ansi -g -D_GNU_SOURCE

Thanks for any help

    the code seems to be ok, but please correct me if I'm wrong. You can
take a look at it bellow (just included the relevant stuff - I hope).
    The library.h is generated by rpcgen from the library.x file. I
would be great if you could take a look at it. Thanks a lot.
