" just modify $AMBERHOME/cmake/CudaConfig.cmake at about line 70 to change
"VERSION_LESS 12.5" to "VERSION_LESS_EQUAL 12.5"."
Prior messages on the list found that CUDA 12.4 was the only tested version
for amber24. CUDA 12.6 causes installation failures so the change suggested
may not work.
The solution was CUDA 11.8

This indicates that your CUDA version is 12.5. Your $CUDA_HOME environment
variable (usually something like /usr/local/cuda) should be a symlink to the
real 12.5 installation is (ususally something like /usr/local/cuda-12.5).
The error message (in the cmake.log file) is this:
-- CUDA version 11.5 detected
-- Configuring for SM3.5, SM5.0, SM5.2, SM5.3, SM6.0, SM6.1, SM7.0, SM7.5
and
SM8.0
-- Checking CUDA and GNU versions -- compatible CMake Error at
cmake/LibraryTracking.cmake:153 (message):
Attempt to import library cublas from nonexistant path
"/usr/local/cuda-11.5/lib64/libcublas.so"
Call Stack (most recent call first):
cmake/CudaConfig.cmake:147 (import_library)
CMakeLists.txt:119 (include)
I'm unsure why it is that /usr/local/cuda-11.5 is being referred to here.
The most likely(?) reason is that /usr/local/cuda is pointing to an old
folder that no longer exists.
Note that Amber24 is distributed with an upper limit on the CUDA SDK of
12.4. You could use the alternatives pathway to go to a lower version --
perhaps one is already present in /usr/local. Or (easier) just modify
$AMBERHOME/cmake/CudaConfig.cmake at about line 70 to change "VERSION_LESS
12.5" to "VERSION_LESS_EQUAL 12.5".
...hope this helps...dac
