I am having a problem with an application I am trying to compile.
I have mysql++ 3.0.7
My SQL Server 5.0 windows exe download
QT 4.4.3
mingw 5.1.4
and Eclipse 3.4.1
I have come along way and have got QT examples compiling and mysql++ examples compiling.
So far however I have only compiled simple1 and interfaces example.
Both build and run okay.
My program has an error:
mingw32-make debug
mingw32-make -f Makefile.Debug
mingw32-make[1]: Entering directory `C:/Users/Entecho/Desktop/Programming/Entecho Config

I think the key part is:
undefined reference to `mysql_free_result@4'
I have read the mailing list a bit and a while ago some people mentioned that the
libmysql.dll was incompatible with GNU make such as mingw because it was compiled with
MSVS.
Is this my problem? Will this be a problem even once I get past my current problem? Any
ideas on how to solve the problem above?
Note that PartsImages is an sql_create_3:
sql_create_3(PartsImages, 1, 3,
mysqlpp::Null<mysqlpp::sql_int>, ImageID,
mysqlpp::sql_int, PartID,
mysqlpp::sql_blob, Image)
Any help much appreaciated.
Kind Regards
