About install OpenRoad problem

[Elon-J]

When I try to install the OpenRoad into a new Machine, at the step: Build using support script './etc/Build.sh', I meet the problem 'collect2: error: ld returned 1 exit status' as below, How can I solve it? Thanks!

Did you use the dependency installer script? What version of tcl do you have? What OS are you using?

[Elon-J]

Yeah, I have used it (including: ./etc/DependencyInstaller.sh -run and ./etc/DependencyInstaller.sh -dev); tclsh version is 8.6; OS is CentOS7.

@Elon-J can you run the following? If there is still an error, please upload the build.log file here.

./etc/Build.sh -clean 2>&1 | tee build.log

[Elon-J]

Yeah, there is still an error; this is the build.log file.

build.log

@Elon-J Try these steps: I am not facing any issues with Centos07 installation

source /opt/rh/devtoolset-8/enable
source /opt/rh/llvm-toolset-7.0/enable
git checkout master
git pull
git submodule init
git submodule update
git submodule sync
git clean -xdi
./etc/Build.sh

Looking at the log and comparing with one from a successful run (also on a Centos7) on the same commit the only difference between our setups are:

# yours
-- Boost  found.
-- Found Python3: /usr/local/lib/libpython3.8.a (found version "3.8.12") found components:  Development
-- Found FLEX: /usr/bin/flex (found version "2.5.37")
# my
-- Found Boost: /usr/local/lib/cmake/Boost-1.72.0/BoostConfig.cmake (found version "1.72.0")
-- Found Python3: /usr/include/python3.6m (found version "3.6.8") found components: Development Development.Module Development.Embed
-- Found FLEX: /usr/local/bin/flex (found version "2.6.4")

Though I suspect these differences would not make any difference in compile. However, I also noticed that in your build there are no .d files or the -MD -MF compile flags -- these flags create the .d files which specify dependencies for the compiler. I have no clue why yours is behaving differently. You could try compiling with a single thread, but that might not solve the issue.

./etc/Build.sh -clean -threads=1 2>&1 | tee build-single.log

I do not see any issues with OpenROAD itself here, happy to try and help you but this looks like an issue with our setup/environment.

@vvbandeira @Elon-J I think it is something to do with the python version

[saicharan0112]

I tried this on a docker container (centos:centos7). I have same Boost version /usr/local/lib/cmake/Boost-1.76.0/ and same FLEX version flex 2.5.37 as @Elon-J . But I have the python version same as @vvbandeira /usr/include/python3.6m/. I am able to build the binary OpenROAD v2.0-4634-g3342b36

[saicharan0112]

And something that is notable is the conda package of the openroad.. it uses python3.7 unlike klayout conda package which uses python3.8. Try installing klayout from conda install -c flaport klayout after installing openroad package. You will see a message that openroad will be removed because of python version differences.

Thanks @saicharan0112 this should work. @Elon-J Please try it.

[saicharan0112]

Here is the installation script for OpenFASoC flow which uses the conda installation approach to install openroad, sky130 pdk, yosys etc. https://github.com/idea-fasoc/OpenFASOC/blob/main/Dependencies.sh Klayout is installed from the .deb or .rpm packages based on the OS

[Elon-J]

@saicharan0112, Thank you, Sai! Let me try it.

[vvbandeira]

@Elon-J any updates? Were you able to fix the issue with the suggestion?

[vijayank88]

@Elon-J Are you able to complete the installation?
