[odb-users] RE: Linux Linking ODB - libtool vs g++

[Szumowski, Thomas]

Looks like my third strike today. :)
I noticed the main difference between the libtool and g++ calls were libtools inclusion of "-Wl,-rpath,/usr/local/lib". Adding that to g++ and naturally it works fine. So perhaps I just need to ensure I have that added in as needed?

Subject: EXTERNAL: [odb-users] Linux Linking ODB - libtool vs g++

I was following the example in the ODB user manual section 2.3 "Compiling and Running". I am on a linux machine. I noticed when I get to the point of running the equivalent command "c++ -o driver driver.o person-odb.o -lodb-mysql -lodb", I get an error. But when I run the make in the examples (hello), it runs libtool and I get no errors. See below for my results. First I link using libtool, as done in the makefile. That works fine and I can execute the program. But then I try the line in the user manual and it fails. Any recommendations? And should I just always use libtool to build?
