[Dev-C++] Problem linking to simple library

[matt <mat...@pa...>]

I am newbie to devcpp but an experienced UNIX programmer. I have the 
simplest example possible that I cannot
get to link. I keep getting undefined reference error even though the 
library is found by the linker (since
when I change the name it complains):
I am using the latest beta version , but the help calls the version 4.9.8.0
Here is the error:

Executing make...
make.exe -f  "C:\Dev-Cpp\Makefile.win" all
gcc.exe votest.o -o "votest.exe" -L"C:/Dev-Cpp/lib" -L"C:/Dev-Cpp/lib" 
-s -mwindows lib/libm.a libtestx.a
votest.o(.text+0x3a):votest.c: undefined reference to `mysub'


Here are the simple sources :
votest.c:
#include "testx.h"


int main(int argc, char *argv[])
{
 int x;

 x = 1;
 x = mysub( x );
 printf("x=%d\n", x);

 system("PAUSE");    return 0;
}



Here is the library source:
textx.c:
#include <stdio.h>


int mysub( int x )
{

  x = x + 1;
 
  return ( x );
 
}

I have no idea at all. Are you sure the library is correctly compiled? 
Is the library stripped? It tends to make the library unusable if it is 
stripped. Apart from that, this should work. If you are an experienced 
UNIX programmer, then it will be no problem for you to write the program 
with a text editor, and compile it by hand, with the same options that 
Dev-C++ uses. Then you can tune it, as long as you get the differences, 
that makes the error. Your example compiled perfectly for me.
