To test the assimp library on GraphFuzz.

[aT0ngMu]

Hi, GraphFuzz is a very effective testing library API's work!!!! However, when I tested the assimp library on GraphFuzz, I encountered some issues.

Here are my steps: 1. git clone --depth=1 https:github.com/assimp/assimp.git 2. mkdir assimp_output 3. gfuzz doxygen --inputs ./sourceCode/assimp --output ./assimp_output 4. gfuzz schema infer ./assimp_output/xml ./assimp_output/schema.yaml 5. gfuzz gen cpp ./assimp_output/schema.yaml .

When I ran the fifth command, I received the following error message:

Is it due to my improper usage or some other reason? Looking forward to your assistance and your message!!! Thanks!!
