Compiling the package: DBD-mysql-4.007.tar.gz and creating the makefile with:

perl.exe Makefile.PL --cflags="-I C:/DBS/mysql-5.0/include" --libs="-L C:/DBS/mysql-5.0/libmysql/release -lmysqlclient -lz -lm -lcrypt -lnsl"

got the below link error:

Addtional Notes:

Compiler VS2003 and latest source mysqlclient.lib.

Just add the flag "/MD" in the Perl create makefile string.

This is a strange bug. Not sure what library missing would cause this. Have you tried an earlier version of DBD::mysql? Just wondering if there's some inadvertent change my last several releases.

Hi Patrick,

Please see my last comment adding the flag "/MD" to call the multi-threaded library resolve the problem for _dosmaperr.

Please disregard my last comment. This link problem *only* happens when compiling the DBD::mysql with the compiler VS2003 and not happens with compiler VS2005.

The Makefile was generated with the below command:

perl.exe Makefile.PL --cflags="-I C:/dbs/mysql-5.0/include" --libs="-L C:/dbs/mysql-5.0/libmysql/release -lmysqlclient -lz -lm -lcrypt -lnsl"

So this could be a compiler bug and not a mysqlclient.lib bug.

actually i still get the same error even with nmake 8.0 from vs2005.

I was able to compile DBD-mysql-4.010 with VS2005 against the package non-install of 5.1.33 (see prior attached file).
