I've been trying now to install grpc (C++) via bazel and cmake.. both have failures.. BUT i thought to myself give conan a try.. but there's an error about protobuf.. so I added it to the requirements and yet it's not helping.. any ideas?

I have the following conan profile:
$ conan profile show default
Configuration for profile default:
[settings]
os=Linux
os_build=Linux
arch=x86_64
arch_build=x86_64
compiler=gcc
compiler.version=11
compiler.cppstd=20
compiler.libcxx=libstdc++
build_type=Release
[options]
[conf]
[build_requires]
[env]
Note that compiler.libcxx is the old ABI (libstdc++) and not the new ABI (libstdc++11). This is intentional. Also I'm specifying cppstd=20.
I then made a custom conanfile for {fmt}, which tries to package up fmt 9.0. That looks like, in its entirety:
from conans import ConanFile, CMake, tools
from conan.tools.cmake import CMakeToolchain, cmake_layout
class ConanFmt(ConanFile):
name = "fmt"
version = "9.0.0"
settings = "os", "compiler", "cppstd", "build_type", "arch"
def source(self):
git = tools.Git(folder="fmt")
git.clone("https://github.com/fmtlib/fmt.git", "9.0.0", shallow=True)
def layout(self):
cmake_layout(self)
def generate(self):
tc = CMakeToolchain(self)
tc.generate()
def build(self):
cmake = CMake(self)
cmake.definitions["FMT_DOC"] = False
cmake.definitions["FMT_TEST"] = False
cmake.definitions["FMT_INSTALL"] = True
cmake.definitions["CMAKE_EXPORT_COMPILE_COMMANDS"] = True
cmake.configure(source_folder="fmt")
cmake.build()
def package(self):
cmake = CMake(self)
cmake.install()
def package_info(self):
self.cpp_info.libs = ["fmt"]
When I try to go ahead and package this up, like say:
$ conan create . demo/testing -s build_type=Release
This does actually go ahead and clone the {fmt} repo, and correctly build and package up the contents of the library.
Except that:
there is no _GLIBCXX_USE_CXX11_ABI definition set (despite what this page) says.
{fmt} was compiled with C++11, not C++20
... but it was built with Release (-O3 -DNDEBUG)
Conan does appear to provide variables like CONAN_CMAKE_CXX_STANDARD=20, CONAN_STD_CXX_FLAG=-std=c++2a, and CONAN_LIBCXX=libstdc++. But {fmt}'s build doesn't actually use those, so that isn't very useful.
How do I actually get conan to propagate through these fields properly? Is that something that must be explicitly specified in the conanfile.py (even if it's in the profile)?

Closed 9 months ago.
I am using the modern conan method for compiling. I am cross compiling an application and am trying to figure out how to convert my existing gcc command to conan / cmake solution.
Here is the gcc command:
arm-linux-gnueabihf-gcc -Wall -static -o sctc sctc.cpp -lm -lstdc++
Pretty simple.
I have successfully built the application using conan/cmake. However it is not running, I think because I am unable to invoke add the options:
-static
-lm
-lstdc++
I think. Also, would like to know how to add -Wall.
How are people debugging the command lines? Any docs or blogs about it?
Here is the conanfile.py

Any pointers to documentation are welcome. I tried searching for answers but was not able to find anything that I thought relevant. I am new to conan and cmake but am enjoying working with both.

I am want to package a CMake project with conan.
For that I use the following conanfile.py:
import os
from conans import ConanFile, tools
from conan.tools.cmake import CMake, CMakeToolchain
from conans.tools import Version
class BaseLibrary(ConanFile):
name = "base-library"
version = "1.0.0"
description = """This is a test project with a library base::io
and base::math and an executable cli."""
license = "MIT"
generators = "cmake_find_package_multi", "cmake_find_package",
default_options = {"fmt:shared": True}
build_policy = "missing" # if this package is build by default if missing.
settings = "os", "compiler", "build_type", "arch"
exports_sources = "*"
_cmake = None
def requirements(self):
if Version(self.version) >= "1.0.0":
self.requires("fmt/8.0.1")
def _configure_cmake(self):
if self._cmake:
return self._cmake
self._cmake = CMake(self)
self._cmake.configure(source_folder=".")
return self._cmake
def build(self):
cmake = self._configure_cmake()
cmake.build()
cmake.install()
def package(self):
cmake = self._configure_cmake()
cmake.install()
tools.rmdir(os.path.join(self.package_folder, "lib", "cmake"))
tools.rmdir(os.path.join(self.package_folder, "lib", "pkgconfig"))
tools.rmdir(os.path.join(self.package_folder, "share"))
def package_info(self):
self.cpp_info.names["cmake_find_package"] = "base"
self.cpp_info.names["cmake_find_package_multi"] = "base"
self.cpp_info.names["pkg_config"] = "base"
which is next to my main CMakeLists.txt file. The CMake project builds without problems and also has a proper install target which installs everything properly: bin,lib,include,share. In CMake I use the conan-cmake module with basically something like this.
When I run
conan create -s build_type=Release . demo/testing
I get the following weird error:

What is the problem here and how can I resolve this? I could not find anything related to this?

I had the same problem and finally found the issue:
The CMake you are importing is the one working with the CMakeToolchain which are both part of the conan.tools.cmake module.
The one that is described in the usage of cmake_find_package[ref] is the one in conans module
So replacing:
from conans import ConanFile, tools
from conan.tools.cmake import CMake, CMakeToolchain
by
from conans import ConanFile, tools, CMake
from conan.tools.cmake import CMakeToolchain
should fix your problem
I have a C++ library which I have successfully exposed to python using Pybind11.
In the CmakeLists.txt file, I have added the numpy include like this:
include_directories("C:\\Python37\\Lib\\site-packages\\numpy\\core\\include")
This works, but is undesirable. I would like to pass the numpy include directory from my setup.py file.
My setup.py file looks very much like this one:

cmake_version = LooseVersion(re.search(r'version\s*([\d.]+)',
out.decode()).group(1))

raise RuntimeError("CMake >= 3.1.0 is required on Windows")
for ext in self.extensions:
self.build_extension(ext)

os.path.dirname(self.get_ext_fullpath(ext.name)))

build_args = ['--config', cfg]

cfg.upper(),
extdir)]

After having a look at some SO questions like this, I know that you can get the numpy include directory with numpy.get_include().
However, adding the include directory to the path inside the function build_extension with this line ext.include_dirs.append(numpy.get_include()) seems to have no effect.
I'd like to know how to pass the include directory properly.
Is your cmake build using the wrong numpy path or not finding numpy at all? If it's the wrong path, you could try prepending instead of appending numpy.get_include():
ext.include_dirs.insert(0,numpy.get_include())
I want to deploy a python / django application on Heroku. In the local environment everything works fine. I use pip to install packages. My requirements.txt is the following:

Your help is appreciated to resolve this issue.
The problem seems to be caused by the presence of a static Python 2.7 library in /usr/local/lib/libpython2.7.a ; to install Reportlab on Heroku correctly using the python-2.7.7 runtime, I changed the order of the directories enumerated by the __call__ function in the inc_lib_dirs class of Reportlab's setup.py file as follows:
Original:
class inc_lib_dirs:
L = None
I = None
def __call__(self):
if self.L is None:
L = []
I = []
if platform == "cygwin":
aDir(L, os.path.join("/usr/lib", "python%s" % sys.version[:3], "config"))
elif platform == "darwin":
# attempt to make sure we pick freetype2 over other versions
aDir(I, "/sw/include/freetype2")
aDir(I, "/sw/lib/freetype2/include")
# fink installation directories
aDir(L, "/sw/lib")
aDir(I, "/sw/include")
# darwin ports installation directories
aDir(L, "/opt/local/lib")
aDir(I, "/opt/local/include")
aDir(I, "/usr/local/include")
aDir(L, "/usr/local/lib")
aDir(I, "/usr/include")
aDir(L, "/usr/lib")
aDir(I, "/usr/include/freetype2")
prefix = sysconfig.get_config_var("prefix")
if prefix:
aDir(L, pjoin(prefix, "lib"))
aDir(I, pjoin(prefix, "include"))
self.L=L
self.I=I
return self.I,self.L
