WSLv1 + Windows IDA Pro Path Issues #738
Open
Description
To my understanding: the documentation for building McSema on windows natively is out of date, no documentation about cross compilation, and no precompiled windows binaries. I have a Windows IDA Pro license and am running McSema (v3.0.22) on WSLv1. Issues arise due to the mcsema-disass-3 script passing arguments to IDA Pro that contain 'Linux format' paths.
mcsema-disass-3passes the path toget_cfg.pyin Linux 'format' to a Windows native install of IDA Pro, due to pathing IDA is unable to locate the script.mcsema-disass-3also makes a temporary copy of the target binary in/tmp/tmp<>and passes the path in Linux 'format' to IDA, which due to pathing, is unable to locate it.
