Hello,

I am running slackware 10 with gcc 3.3.4.

I have build mysql source 4.1.10 successfully and installed it in
/usr/local/mysql-source

I then compiled mysql++-1.7.31 with

../configure --with-mysql=/usr/local/mysql-source/

I then ran reset-db host user password and the database was created. I
then copyed the sample from the web site and tried to compile it.

It complained it could not find mysql.h so I added the directory
"/usr/local/mysql-source/include/mysql/" to my compilers include path.

I then tried to compile the sample progject simple1.cc and I receive a
number of errors. I am using Anjuta 1.2.2 for my IDE.

Anjuta does the following commands:
g++ -DHAVE_CONFIG_H -I. -I. -I..
-I/usr/local/mysql-source/include/mysql/ -Wall -g -MT main.o -MD -MP -MF
".deps/main.Tpo" -c -o main.o main.cc

which seems to be ok but complains about sqlplus.hh being old and
switching to mysql.h and then Anjuta runs:

/bin/sh ../libtool --mode=link g++ -Wall -g -o mysql_plustest main.o

which returns:

If I switch #include <sqlplus.hh> for #include <mysql++.h>

and run:

g++ -DHAVE_CONFIG_H -I. -I. -I..
-I/usr/local/mysql-source/include/mysql/ -Wall -g -MT main.o -MD -MP -MF
".deps/main.Tpo" -c -o main.o main.cc

I then received:

--snip--

Anyways ... thanks for any replies ...

The example programs should've been included with the package, so you
shouldn't have needed to copy them from the website. They're in the
example directory.

Secondly, you need to convince Anjuta (never used it, so I dunno how) to
include -lmysqlpp and -lmysqlclient and possibly -L/path/to/mysql and
-L/path/to/mysqlpp so it can link to the proper library.

Hello,

Thanks for the reply ... I am using the copy from the examples
directory, which is different from the one in the documents from the web.

The readme in the example directory said the examples should of been
built ? Mine were not

Anyways ... I tried compiling the simple1.cpp from command line and got
a little further:

g++ -I/usr/local/mysql-source/include/mysql
-L/usr/local/mysql-source/lib/mysql -L/usr/local/lib -lmysqlpp
-lmysqlclient simple1.cpp

I had to provide the path for the mysqlclient libs, so I also added in
the path for mysqlpp

/tmp/ccXfsEPj.o(.text+0x39): In function `main':
: undefined reference to `connect_to_db(int, char**,
mysqlpp::Connection&, char const*)'
/tmp/ccXfsEPj.o(.text+0x89): In function `main':
: undefined reference to `print_stock_table(mysqlpp::Query&)'
collect2: ld returned 1 exit status

It still seems like it is missing a libaray or something ?

Thanks again ...

Michael.

Those are in util.cpp, so if you're linking it by hand, link with util.o
-- but I'm not clear on what's going on. Did you go into the examples
directory and just type 'make'?

Then find out why. I assure you, the examples should indeed get built
automatically. If they aren't getting built, you have a real problem
you need to address; don't just ignore it.

And once you get them building automatically, look at
examples/Makefile.simple for ideas when setting up your IDE.

Hey,

Ya ... I tried just running make in the begining ... I believe the
message was "make ... No needs to be done" or something like that.

Just ran it again and received

"make: *** No rule to make target `../lib/libmysqlpp.la', needed by
`resetdb'. Stop."

This is most likely because I ran a make clean and few minutes ago.

If I enable debugging I get:

/tmp/ccnxhejy.o(.text+0x39): In function `main':
/usr/include/c++/3.3.4/sstream:143: undefined reference to
`connect_to_db(int, char**, mysqlpp::Connection&, char const*)'
/tmp/ccnxhejy.o(.text+0x89): In function `main':
/usr/include/c++/3.3.4/bits/sstream.tcc:191: undefined reference to
`print_stock_table(mysqlpp::Query&)'
collect2: ld returned 1 exit status

I will build mysql++ again and run make again ...

AHHH ... ok this time all the example binary's where built.

Thanks anyways ...

Michael.
