`Could NOT find Boost: missing: python37`

kldavis4 opened this issue 5 years ago · 6 comments

I'm having trouble getting these to build with homebrew python3 on mojave. I have installed boost and boost-python3 and made the following changes to build.sh to tell it to use python3:

 if [[ "$OSTYPE" == "linux-gnu" || "$OSTYPE" == "linux" ]]; then
     cmake -DPYTHON_VERSION_SUFFIX=-py3 -DCMAKE_BUILD_TYPE=DEBUG .. && make && make test
 elif [[ "$OSTYPE" == "darwin"* ]]; then
-    PYTHON_VERSION=`python -c "import sys;t='{v[0]}.{v[1]}'.format(v=list(sys.version_info[:2]));sys.stdout.write(t)";`
+    PYTHON_VERSION=`python3 -c "import sys;t='{v[0]}.{v[1]}'.format(v=list(sys.version_info[:2]));sys.stdout.write(t)";`
     PYTHON_LIBRARY=/usr/local/Frameworks/Python.framework/Versions/$PYTHON_VERSION/lib/libpython$PYTHON_VERSION.dylib
     PYTHON_INCLUDE_DIR=/usr/local/Frameworks/Python.framework/Versions/$PYTHON_VERSION/Headers/
-    cmake -DPYTHON_LIBRARY=$PYTHON_LIBRARY -DPYTHON_INCLUDE_DIR=$PYTHON_INCLUDE_DIR -DCMAKE_BUILD_TYPE=DEBUG .. && make && make test
+    cmake -DPYTHON_EXECUTABLE=/usr/local/bin/python3 -DPYTHON_LIBRARY=$PYTHON_LIBRARY -DPYTHON_INCLUDE_DIR=$PYTHON_INCLUDE_DIR -DCMAKE_BUILD_TYPE=DEBUG .. && make && make test
 elif [[ "$OSTYPE" == "cygwin" ]]; then
     : # POSIX compatibility layer and Linux environment emulation for Windows
 elif [[ "$OSTYPE" == "msys" ]]; then

When I execute it I get the following:

++ basename ./build.sh
+ cd ./
+ mkdir build
mkdir: build: File exists
+ cd build
+ [[ darwin18 == \l\i\n\u\x\-\g\n\u ]]
+ [[ darwin18 == \l\i\n\u\x ]]
+ [[ darwin18 == \d\a\r\w\i\n* ]]
++ python3 -c 'import sys;t='\''{v[0]}.{v[1]}'\''.format(v=list(sys.version_info[:2]));sys.stdout.write(t)'

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.

Trying to understand how to resolve: Could NOT find Boost: missing: python37 (found /usr/local/lib/cmake/Boost-1.71.0/BoostConfig.cmake (found version "1.71.0"))

Seems to be a cmake problem. Even if all the documented variables are set, cmake is not able to recognize the boost installation. Everything else seems to be following from this problem.

Answer 2 · 2019-09-14T13:10:28.000Z

After looking further into it, I assume this be a problem with homebrew's packaging of boost-python:

CMake Error at /usr/local/Cellar/boost/1.71.0/lib/cmake/Boost-1.71.0/BoostConfig.cmake:117 (find_package):
  Could not find a package configuration file provided by "boost_python"
  (requested version 1.71.0) with any of the following names:

    boost_pythonConfig.cmake
    boost_python-config.cmake

Respective files are available for all other boost components (as part of the boost package), but are missing for boost-python and boost-python3. Adding them to one of the packages (and I don't know which would be the right one), should solve the problem.

@Achimh3011 thanks for looking into this - it helped a lot. I found this YosysHQ/nextpnr#322 (comment) and set
set(Boost_NO_BOOST_CMAKE true) and was able to get the build to succeed.

Cool! Would you like to make a PR with the work-around for this repo?

sure thing - I will make a PR

Removed the requirement from the CMakeLists.txt
changed to: find_package(Boost REQUIRED python)
