Environmental statement

 The original environment ：cuda10.0

 New environment ：cuda10.2

Although the two versions are very close , But directly put cuda10.0 The project is packaged into 10.2 There will be a series of problems in running . Because of the new contact cuda No , Write these questions slightly .

Question 1 ： Unable to load project

Open for the first time from 10.0 The copied project vs Prompt loading failed

resolvent ： Right click the project name —>> edit , Search the open page for 10.0 Replace all with 10.2 （ The original cuda yes 10.0 edition , The new environment is 10.2 edition ）
This is a cuda Caused by an inconsistent version

Question two ： Can't find h、lib file

h Some of the documents are written by themselves , There are plenty of them cuda Self contained , You need to add these two h Path to file
lib The file also reported an error due to the absence of a path
resolvent ： Right click the item name –>> attribute –>> Configuration properties –>>vc++ Catalog After opening, you can see many directories , Here we need to use the include directory and Library Directory , take h Add the path of the file to the include directory , take lib Add the directory of the file to the Library Directory

Question 3 ： Unrecognized external symbol

After solving problem 2, compile again , Prompt unrecognized external symbols , Are some of the common cuda Functions such as cudaEventCreate、cudaEventSynchronize etc.
resolvent : Right click the item name –>> attribute –>> Configuration properties –>> The linker –>> Additional dependency Add what you need cuda Library filename

Some common ones are ：
cublas.lib
cuda.lib
cudadevrt.lib
cudart_static.lib
cudart.lib
Be careful ： If you write it yourself lib The file should also be added here

Question 4 ： Can't find dll file

There are two scenarios ： One is written by yourself dll file ; The other is cuda Self contained dll file

Case one ： The simplest solution is to write your own dll Copy the file to the output folder of the project , That is to say, generate exe Where the papers are

The second case ： find cuda Installation directory , Refer to the below , Finally open bin Folder

Carry out the following operations according to the prompted information , For example, my hint is that I can't find cudart64_100.dll Document and cublas64_100.dll file
find bin Folder and prompt can not be found dll Files with similar file names , For example, we can't find cudart64_100.dll, however bin There are cudart64_102.dll file , Then make a copy cudart64_102.dll Change file name to cudart64_100.dll, Put it in the same way bin Under the folder .cublas64_100.dll Operate like a file , The above figure shows the after the copy is completed .
