libmysql.dll : fatal error LNK1136: invalid or corrupt file

Hi all,

This is my simple source code:

#include
#include

#define def_host_name "localhost"
#define def_user_name "root"
#define def_password "passwork"
#define def_db_name "test"

MYSQL *conn;

int main(int argc, char *argv[])
{
printf("Hello, world and Goodbye\n");
}

//END

I have compiled it using:


C:\project\code>cl -c -I "C:\Program Files\MySQL\MySQL
Server 4.1\include" clien
t1.c
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version
13.10.3077 for 80x86
Copyright (C) Microsoft Corporation 1984-2002. All
rights reserved.

client1.c


I got the following error while linking the .obj file,
below is the error:

C:\project\code>cl client1.obj -link "C:\Program
Files\MySQL\MySQL Server 4.1\li
b\opt\libmysql.dll"
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version

Microsoft (R) Incremental Linker Version 7.10.3077

/out:client1.exe
"C:\Program Files\MySQL\MySQL Server
4.1\lib\opt\libmysql.dll"
client1.obj
C:\Program Files\MySQL\MySQL Server
4.1\lib\opt\libmysql.dll : fatal error LNK11
36: invalid or corrupt file


Thanks in advance.

By the way anyone can advice on how I can reply to
your replies. I dunno how to reply to this thread.

Re: libmysql.dll : fatal error LNK1136: invalid or corrupt file

You don't link against DLLs, you link against import LIBs for DLLs. So
libmysql.dll comes with a very small libmysql.lib (which contains
information on which functions exist in the DLL). Link against that.

Or you can do what I prefer to do, which is staticly compile libmysql.lib so
there is no DLL, and link against that. I prefer not to use the DLL due to
performance reasons and difficult to debug DLL mismatches. If you run a
program linked to a particular version of the DLL, but the DLL in your path
is the wrong one, you can get freezes, abnormal crashes, etc, which happen
before your first breakpoint in a debugger (when the DLL load is triggered
during initialization). Dynamic library function calls also have a minor
performance penalty (something addressed by AMD in their x86-64
architecture), and I have no need to save the disk space of having my EXEs
be a meg smaller by sharing an DLL with other programs. It's just not worth
it.

Good luck with your project.

RE: libmysql.dll : fatal error LNK1136: invalid or corrupt file

It's not just on disc that DLLs save space. If you are running lots of
EXEs with the same code statically linked, then there will be multiple
copies of that code in memory. If you use a DLL, there will be only one
copy. Depending on your situation this might prevent paging and increase
the throughput of your machine. If you are only running a few copies, it
probably does not matter.

Re: libmysql.dll : fatal error LNK1136: invalid or corrupt file

True, but hopefully people aren't paging on modern machines over an extra
1MB of memory usage for each MySQL client application. :)

Re: libmysql.dll : fatal error LNK1136: invalid or corrupt file

Hi Jeremiah Gowdy,

Thanks for your help. I linked against the
libmysql.lib and have manage to compile a simple code
to connect to and do a "show tables from test".

Thanks again.
Regards
