Bug ID: 55528
           Summary: Vitis 2020.1 can't find its libraries (cmd.exe bug
                    with nested one-line if statement that sets PATH)
           Product: Wine
           Version: 8.15
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

Terminal output

Steps to reproduce:

1. Run `tar -xvf Xilinx_Unified_2020.1_0602_1208.tar.gz`

2. Run `wine Xilinx_Unified_2020.1_0602_1208/xsetup.exe`

3. When the installer complains that it can't connect to the internet, click
Ignore

4. Run `XIL_PA_NO_REDIST_CHECK=1 wine 'C:\Xilinx\Vitis\2020.1\bin\vitis.bat'`

The following errors are printed to the terminal:

Syntax error
Can't recognize ')' as an internal or external command, or batch script.
0138:err:module:import_dll Library libboost_filesystem.dll (which is needed by
L"C:\Xilinx\Vitis\2020.1\bin\unwrapped\win64.o\rdi_vitis.exe") not found
0138:err:module:import_dll Library libboost_program_options.dll (which is
needed by L"C:\Xilinx\Vitis\2020.1\bin\unwrapped\win64.o\rdi_vitis.exe")
not found
0138:err:module:import_dll Library librdi_common.dll (which is needed by
L"C:\Xilinx\Vitis\2020.1\bin\unwrapped\win64.o\rdi_vitis.exe") not found
0138:err:module:LdrInitializeThunk Importing dlls for
L"C:\Xilinx\Vitis\2020.1\bin\unwrapped\win64.o\rdi_vitis.exe" failed,
status c0000135

I was able to narrow down the problem to code in loader.bat that looks similar
to this (this is a minimal example, these aren't the real variable names):

set FOO=1
if %FOO% == 1 (
    if %FOO% == 1 set PATH=C:\Xilinx\Vitis\2020.1\lib\win64.o;%PATH%
    if %FOO% == 1 (
         echo %PATH%
    )
)

I don't know why Wine thinks that there is a syntax error in this code. There
must be a bug in the command parser that is triggered by a nested one-line if
statement that sets a variable.

Registration is required to download Vitis.
