In a file called config.log, I found lines like the follow:

configure:18036: checking for function pardiso_ in -lmkl_intel_lp64 
-lmkl_sequential -lmkl_core -lm
configure:18061: gcc -o conftest -O2 -DNDEBUG    conftest.c 
-lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm  >&5
configure:18061: $? = 0
configure:18070: result: yes


IPOPTLIB_LFLAGS='-L/usr/local/lib -lcoinmumps  -lmkl_intel_lp64 
-lmkl_sequential -lmkl_core -lm -lm  -ldl'
IPOPTLIB_LFLAGS_NOPC=' -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm 
-lm  -ldl'

Original message:

I have a Linux ubuntu OS which came with the mkl blas. The IPOPT 
seemed to imply that IPOPT would be able to find them. Is there some way 
me to verify that IPOPT is using the mkl blas on my system? These are 
the only
blas on my system and they are in the default location where ubuntu puts 
Please advise. Thank you.
