免责声明：我在研究编译错误详细信息之前问了这个问题。 这个问题包含了这里解释的问题的答案。简而言之，异常定义中的变量类型定义错误会阻止综合的正确发生。
除非您愿意找到正确的
gcc我正在尝试运行示例代码，如 hls4ml 的文档页面所示，但运行以下命令：
import hls4ml
#Fetch a keras model from our example repository
#This will download our example model to your working directory and return an example configuration file
config = hls4ml.utils.fetch_example_model('KERAS_3layer.json')
print(config) #You can print it to see some default parameters
#Convert it to a hls project
hls_model = hls4ml.converters.keras_to_hls(config)
#Use Vivado HLS to synthesize the model
#This might take several minutes
hls_model.build()
#Print out the report if you want
hls4ml.report.read_vivado_report('my-hls-test')
输出是

请注意，最后两行指的是构建过程和报告的返回。
我通过 Anaconda Navigator 在 Jupyter Notebook (6.0.3) 上运行它，Python 版本是 3.6.9，hls4ml 版本是 0.5.0
我不明白这是由于安装错误还是由于代码等等原因。
对于造成这种情况的原因有什么想法吗？
我认为这是 hls4ml 特有的，但遗憾的是它在 StackOverflow 中不作为标签存在。

我在新版和旧版 Vivado HLS 上都遇到过这个问题。我该如何解决这个问题？
我遇到了同样的问题，hls4ml 是 Linux 的后端 Vivado（截至目前）。这在 Ubuntu 中不是问题。 不支持Windows，有一个文件专门在合成前验证操作系统。
如果您转到构建 hls 模型的目录，则在
build_lib.sh我不知道为什么它不起作用，但他们正在根据操作系统设置C++编译器here

我有同样的问题：未找到联合模拟。有谁能解决这个问题吗？
