Changes and Additions to CppAD During 2024
mm-dd
01-16
fix dll linking of jit code by changing cppad_c_compiler_path to cppad_c_compiler_cmd (spaces in the path were making commands fail).
01-12
There were some problems using the cmake C compiler for the examples and tests of jit compilation, so that has been backed out for now.
There was a mistake in detecting if size_t is the same as cppad_tape_addr_type. This could cause a compile error in op_hash_table.hpp and has been fixed.
01-11
Use the cppad_c_compiler_path detected by cmake to run the C compiler for the Clang and GNU cases; see the create_dll_lib` defaults for compile and link .
01-10
Fix some problems with the install on 32 bit systems. To be specific, the thread_alloc memory allocator was not properly aligning doubles.
Suppress the test of the
svec_setvec
class. (The class has a bug and is not currently being used.)
01-08
On some systems unsigned int
and size_t
are the same type
and this would cause a compile error in vector.hpp
and
vector_bool.hpp
. This has been fixed.
01-07
The forward_two Syntax was corrected.
To be specific,
Forward
(1, x2 ) was changed to Forward
(2, x2 ) .
In addition, some other minor improvements were made to the
forward_two documentation page.
01-03
The change on 12-24 2023, when cppad_debug_and_release was implemented, was not done properly and might cause a mistaken assertion. This has been fixed.
Each file_name in the latest documentation was moved (this is important if you have links to previous web pages):

01-02
The compare_change.cpp example/test would sometimes fail when cppad_debug_which was
debug_even
ordebug_odd
(because it was compiled for debugging and including a release version of a utility). This has been fixed by making this example/test a separate program.The vectorBool constructor would generate a warning when called with an
int
for the size of the vector (on some compilers). This has been fixed.
