tuxedo9 db2 9.0

Question

my system is SUSE Linux 10.1  X86

the Tuxedo is 9.1....DB2 is V9.0.

all has been configured successfully..but the esql/c problem

error: sqladef.h: No such file or directory

I know the reason is that the system can not find the "/opt/ibm/db2/V9.1/include" directory

so the header files with ".h" append ...could not be found by tuxedo.....

so it can not pass compiling....

who can tell me the solution of this....

very thanks...
