Help with user fork build of ORFS

[gudeh]

Hey guys, I have been working with my own fork of ORFS for about a year:

I have always been able to keep up to date with latest changes of ORFS on my fork. Although recently I got into some compilation errors which I could not handle by myself.

If I leave .gitmodules file as is, for some reason I get the following errors, right at the beginning of "./build_openroad.sh":

[INFO FLW-0002] Updating git submodules.

Notice how it sets up a git url with my user, which it did not use to happen before. For this reason I modified .gitmodules with the complete path and got another error.

If I change .gitmodules like the following, the build goes on until it provides the following error (I am skipping installing of Yosys because of EQY issue):

.gitmodule:

[submodule "tools/yosys"]
	path = tools/yosys
	url = ../../The-OpenROAD-Project/yosys.git

[submodule "tools/OpenROAD"]
path = tools/OpenROAD
url = https://github.com/The-OpenROAD-Project/OpenROAD.git

[submodule "tools/LSOracle"]
path = tools/LSOracle
url = https://github.com/The-OpenROAD-Project/LSOracle.git

Build error:

[ 88%] Building CXX object src/drt/CMakeFiles/drt.dir/src/distributed/frArchive.cpp.o

If use the original ORFS it compiles successfully and runs with manual installed EQY.

I also have a question. Can I install multiple versions of ORFS on the same system? Are all the tools contained to the project folder, or does ORFS installs binaries on the system?

I'm guessing this relates to #1370 . If you locally undo that change does it solve your problem?

@vvbandeira any ideas?

[gudeh]

I tried to undo the modifications on .gitmodules, retry "build_openroad.sh --local" (without clean) and the build error shows up again in another percentage progression, although with the same error text:

The error

/home/gudeh/Desktop/OpenROAD-flow-scripts/tools/OpenROAD/src/pdn/src/sroute.cpp:507:14: error: ‘cout’ is not a member of ‘std’
  507 |         std::cout << "xmax is " << pdn_wire->xMax() << std::endl;
      |              ^~~~

has been fixed. Please update and try again.

@gudeh

• Have you tried to clone the repo again?
• You can have as many ORFS clones as you want in your system, the build_openroad.sh just builds the binaries. They are not installed in your system by default.
• Which version of git and which OS are you using?

@vvbandeira

Have you tried to clone the repo again?

Yes. Actually, I was only able to build on my fork by doing "git reset --hard " to a commit of mine from april: db55b08
I guess that I was able to build with merges between April and now because I did not go for a clean build.

You can have as many ORFS clones as you want in your system, the build_openroad.sh just builds the binaries. They are not installed in your system by default.

This is great under my situation.

Which version of git and which OS are you using?

git version 2.34.1

I wonder if everyone's forks are also having this build issue.

[vvbandeira]

Looking at your user's repos, it does seem that you don't have a fork of OR.
Could you try to fork that as well?

Indeed that solved the problem! No need to modify .gitmodules!
