cppad/cppad.hpp. This has been fixed.
ADVector, were in the global namespace and this was causing warnings about the shadowing of these declarations. The cppad_ipopt namespace was created to avoid these problems. The simplest way to make old cppad_ipopt_nlp code work with this change is to use the command

test_time(it used to always run at least two).
sum_i_inv_time.cppand multi_newton.cpp routines were calling the test an extra time at the end to check for correctness. The results of the last test are now cached and used for the correctness test so that an extra call is not necessary (to make the tests run faster when only a few repetitions are necessary).

pthreadlibrary does not include the
pthread_barrier_waitfunction; i.e., is not compliant with the IEEE Std 1003.1, 2004 Edition for
pthread. This caused the
pthread_simple_ad.cppto fail to compile on the MAC. This has been fixed by not compiling the
r_k (u)such that
pthread_simple_ad.cpp, including avoiding a Bug in Cygwin .
openmp/run.cppwas not setting the number of threads for the one thread case (so dynamic thread adjustment was used). This has been fixed.
example/example.vcprojfile and a attempt was made to link to missing OpenMP routines (this has been fixed). In addition, some Microsoft compiler warning have been fixed; see the examples and tests in the Windows install instructions.
CPPAD_MAX_NUM_THREADwas being set to 2 when
_OPENMPwas not defined. This has been fixed and CPPAD_MAX_NUM_THREADS has been documented and is now part of the CppAD API.
pthread_simple_ad.cpptest failed under cygwin. This was because the previous test
openmp_ad.cppwas set up calls to OpenMP routines that were still in effect when
pthread/simple_adran. This has been fixed by making
num_threads == 1a special case in parallel_setup .
