Create the shared library

You must compile dynthr.c into a shared or static library. The following example illustrates how to compile a shared or static library on a workstation running the Solaris operating system:

% cc -c -DIFX_THREAD -I$INFORMIXDIR/incl/esql -D_REENTRANT -K pic 
dynthr.c
% ld -G -o libdynthr.so dynthr.o
% cp libdynthr.so /usr/lib             <== as root

You can also use the $LD_LIBRARY_PATH environment variable:

% cc -c -DIFX_THREAD -I$INFORMIXDIR/incl/esql -D_REENTRANT -K pic 
dynthr.c
% cp dynthr.so <some directory>
% setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:<some directory>

To compile dynthr.c into a static library, perform the following tasks (on Solaris):

% cc -c -DIFX_THREAD -I$INFORMIXDIR/incl/esql -D_REENTRANT dynthr.c

% ar -cr dynthr.a dynthr.o

You must update your application, test.ec, to call the dynthr_init() routine first, or none of the thread functions are registered.

void main(argc , argv )
int argc;
char *argv[] ;
{    /* begin main */
         
   /* First, set up the dynamic thread library */
         
   dynthr_init();
         
   /* Rest of program */
         
   EXEC SQL database stores7;
   
;
