Build error

[Edu4rdSHL]

Hello,

I'm trying to add dynStruct to BlackArch Linux but I have the following error:

[edu4rdshl@blackarch dynStruct]$ sudo DynamoRIO_DIR=/usr/share/dynamorio ./build.sh 
CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

  The cmake-policies(7) manual explains that the OLD behaviors of all

  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

Can you explain what's happening there? Because DynamoRIO_DIR is correclty setted.

Hi, I've never seen this error before. Maybe it's due to some changes in DynamoRIO, can you tell which version you are trying to build with ? I'll try to take a look today to see if I can reproduce.

[Edu4rdSHL]

I'm using the latest DynamoRIO master version. Thank you.

[ampotos]

I have the same issue with the latest release, I'm trying to find a fix.

[ampotos]

The issue seems similar to https://github.com/DynamoRIO/dynamorio/pull/3476. A fix was merge in master the 9 of April. So the last release will not work (released 22 of Februrary). You need to wait a new release or use a more recent of their cronbuild (https://github.com/DynamoRIO/dynamorio/releases). I'm tested to build with the latest cronbuild in 5 mins

EDIT: I just build successfully using the lastest cronbuild https://github.com/DynamoRIO/dynamorio/releases/tag/cronbuild-7.91.18109

[Edu4rdSHL]

Thank you for the heads up. I will switch to git version for that package and see if it works.

Can you leave the issue open still I test today with the latest master commit of Dynamorio and see what happens? It the build end success I will close it issue.

[ampotos]

No problem I let you close it when you confirmed that it's working on your side as well.

[Edu4rdSHL]

Worked with latest cronbuild, thanks!

Edit:

I will add dynStruct to our BlackArch distro when a new dynamorio release will be added.
