Compilation hangs when compiling .xo files.

[logosAllen]

Dear Authors,

With the 20240301 release, while I run

cd apps/vadd
source run_tapa.sh

TAPA will stock at

OS: Ubuntu 20.04.6 Vitis version: 2022.2

How to solve this problem?

Thanks

After upgrade to Vitis 2023.2, the same problem happened. But it show that

initialization failed: couldn't load file "libxv_commontasks.so": libtinfo.so.5: cannot open shared object file: No such file or directory

so after install libtinfo5, the .xo file can be compiled. This issue may happen only on virtual machine, since I install the minimal set of OS

sudo apt-get install libtinfo5

Thanks

@logosAllen Does HLS hang if you run it by itself without TAPA? I suspect this is a general issue with Vitis HLS; you just need to install libtinfo :(

Here is a list of packages I install to Ubuntu (20.04 and 22.04) to run Xilinx tools:
