compiler_args

This is the reference page for compiler_args generator. Go to Integrations/Compilers on command line if you want to learn how to integrate your project calling your compiler in the command line.

Generates a file named conanbuildinfo.args containing a command line parameters to invoke gcc, clang or cl compiler.

You can use the compiler_args generator directly to build simple programs:

gcc/clang:

> g++ timer.cpp @conanbuildinfo.args -o bin/timer

cl:

$ cl /EHsc timer.cpp @conanbuildinfo.args

gcc/clang

You can also use it in a recipe:

from conans import ConanFile

class PocoTimerConan(ConanFile):
   settings = "os", "compiler", "build_type", "arch"
   requires = "Poco/1.9.0@pocoproject/stable"
   generators = "compiler_args"
   default_options = {"Poco:shared": True, "OpenSSL:shared": True}

   def imports(self):
      self.copy("*.dll", dst="bin", src="bin") # From bin to bin
      self.copy("*.dylib*", dst="bin", src="lib") # From lib to bin

   def build(self):
      self.run("mkdir -p bin")
      command = 'g++ timer.cpp @conanbuildinfo.args -o bin/timer'
      self.run(command)
