When including a library, you don't actually include the 'lib' or '.so' part.

Here is the command I was using to compile my first test program called testconnect: g++ -g -lz -L../lib/lib -lsqlplus -L/usr/lib/mysql -lz -lmysqlclient -I../lib/include -I. -L. -I/usr/include/mysql -o testconnect testconnect.cc

It probably has options you don't need, but it worked for me... Charlie

Hi all,

someone can explain me how I get compiled a programme with the mysql++-API.

I tried many things. For example:

--------- g++ -I/home/users/jens/local/mysql++-1.7.8/include -I/usr/local/mysql/include/mysql ./login/JWmysql.cpp -L/usr/local/mysql/lib/mysql -l/home/users/jens/local/mysql++-1.7.8/lib/libsqlplus.so -lmysqlclient

---------

The error is:

--------- /usr/bin/ld: Can't locate file for: -llibsqlplus.so collect2: ld returned 1 exit status

---------

'libsqlplus.so' is in '/home/users/jens/local/mysql++-1.7.8/lib' I also have it in the LD_LIBRARY_PATH

I tried it with kdevelop:

--------- ####### kdevelop will overwrite this part!!! (begin)########## bin_PROGRAMS = login login_SOURCES = JWmysql.cpp main.cpp JWstring.cpp JWcgi.cpp login_LDADD = /home/users/jens/local/mysql++-1.7.8/lib/libsqlplus.so

EXTRA_DIST = JWcgi.cpp JWcgi.h JWstring.cpp JWstring.h main.cpp JWmysql.cpp JWmysql.h

####### kdevelop will overwrite this part!!! (end)############

#INCLUDE = /usr/local/mysql/include/mysql /home/users/jens/local/mysql++-1.7.8/include

CPPFLAGS= -I/usr/local/mysql/include/mysql -I/home/users/jens/local/mysql++-1.7.8/include

-----------

this is the message I got:

----------- bla bla... g++ -O0 -g3 -Wall -o .libs/login JWmysql.o main.o JWstring.o JWcgi.o /home/users/jens/local/mysql++-1.7.8/lib/libsqlplus.so -L/usr/local/mysql/lib/mysql -lz /usr/local/mysql-3.23.32/lib/mysql/libmysqlclient.so -Wl,-rpath -Wl,/home/users/jens/local/mysql++-1.7.8/lib:/usr/local/mysql-3.23.32/lib/mysql /usr/bin/ld: /usr/local/lib/gcc-lib/alphaev6-dec-osf4.0f/2.95.2/libstdc++.a(streambuf.o): streambuf::uflow(void): multiply defined /usr/local/lib/gcc-lib/alphaev6-dec-osf4.0f/2.95.2/libstdc++.a(streambuf.o): streambuf::xsputn(char const *, long): multiply defined /bla bla...

------------

Changing the order of flags or adding some others I get different errors.

PLEASE. if there is a way to compile and link a programme with the mysql++-API, tell me how to do it.

Best regards,
