Hi List.
I'm new to using MySQL++, and not particularly experienced with
hugely complex projects.. So I hope everyone will be patient with me as
I ask a few really simple-minded questions. Pointers to reading
material are always appreciated as responses to my questions.

So here we go. I have a source file:

testmysql.cpp:

#include <stdio.h>
#include <mysql++.h>

int main (void) {

return 0;
}


That's it, seriously. Does absolutely nothing but exit with a zero
return value. And....it won't build under my minimal skillz.

% g++ -I/usr/local/include/mysql++ -o testmysql testmysql.cpp

results in (as you experienced folks might guess) a huge vomitous mass
of compiler errors.

So obviously even the inclusion of the mysql++.h header carries with it
a number of prerequisites I'm not meeting.

Understand that I have no experience with such things as projects where
tons of g++ command-line switches are being used. My above example
command line has been enough for the small projects I've worked on in
the past. I know nothing of the -Ms, the -gs, the -O2s (although at
least I know that last one has something to do with compiler
optimizations).. But I hate to think just using this library has turned
an otherwise innocuous project into more than I can chew. I really
think I can learn what I need to learn, but I don't know where to go to
find the info to learn it.

Would someone mind being patient enough to give me a bit of a
kick-start? I'd surely appreciate it.

Cheers and many thanks in advance,
~Brian

Brian,

I'm using gcc on RHEL. These are some of the things I had to do to get my
stuff compiled:

1. Make sure I had all the necessary MySQL and MySQL ++ components:

a. Server
b. Client
c. Headers and Libraries
d. Shared Libraries


2. Had to run the following command to configure my shared libraries

/sbin/ldconfig /usr/local/lib

And add the following line to /etc/ld.so.conf

/usr/local/lib

3. In my makefile include the proper libs. For example I have the following
macro substitutions in my makefile:

# Specify include path for mySQL header files
CCFLAGS += -I/usr/include/mysql

# Specify include path for mySQL++ header files
CCFLAGS += -I/usr/local/include/mysql++

# Specify include path for mySQL client library
LDFLAGS += -L/usr/lib/mysql -lmysqlclient

# Specify include path for mySQL++ library
LDFLAGS += -L/usr/local/include/mysql++ -lmysqlpp

Hope this helps,

Steve

Rebuild the examples and observe the g++ commands given when you say 'make'.
