QUESTION

Can you have a common cmake minimum included from another file?

Asked 2019-Aug-24 at 13:28

I am quite new to cmake with a makefile background.

I like to use things like include(cmake_utils/header.cmake) to include common snippets of cmake files so that I can include them in my projects but only change them in one once in one place. Where cmake_utils is a git repo.

This is working nicely, but every single CMakeLists.txt I write has to have a cmake_minimum_required.

That is fine, but I may want to change this one day - lets say when one of my common files uses a feature from a newer version of cmake. In that case I don't want to go around changing all the CMakeLists.txt - I just want to change it in one place (ideally).

Here is my current CMakeFile.txt:

Per the documentation cmake_minimum_required: Call the cmake_minimum_required() command at the beginning of the top-level CMakeLists.txt file even before calling the project() command. It is important to establish version and policy settings before invoking other commands whose behavior they may affect.

There is no way of getting around this.

QUESTION

cmake target_compile_options worked but add_compile_options did not

Asked 2019-Aug-24 at 11:18

I am have a make (gnu make) background and am learning cmake for my c++ projects.

My system is a ubuntu VM: Linux osboxes 4.15.0-46-generic #49-Ubuntu SMP Wed Feb 6 09:33:07 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I am a bit confused by this answer here. It says that I can do either of:

target_compile_options(${PROJ_NAME} PRIVATE -w)
add_compile_options(${PROJ_NAME} PRIVATE -w)

I am compiling log4cpp code which when compiled with standard warning levels gives a load of warning. Its 3rd party code so I don't want to hear about them. Therefore I use gcc/g++ -w flag.

When I used the target_compile_options as above it works fine (no warning seen) but when I used the add_compile_options it did not work for me (i.e. I see all the errors as though -w is not applied). I am not sure what I am doing wrong here (but probably something!).

Here is my CMakeLists.txt file for reference:

Command add_compile_options affects only on the targets, which are created after the command is invoked. Current command documentation says:

Adds options to the COMPILE_OPTIONS directory property.

(Further created targets initialize their property with the directory's one, but previously created targets are unaffected by this directory property).

Because you call add_library before the add_compile_options, this library's options are not changed.

But the command add_definitions affects on previously created targets too. From its documentation:

Adds definitions to the compiler command line for targets in the current directory and below (whether added before or after this command is invoked).

QUESTION

Configuring log4cpp Logging level Priority

Asked 2018-Apr-13 at 15:36

In an application we are using log4cpp-0.3.5rc3 for logging. The application is installed on linux devices. There is a bug in application and I want to set the log level of application to debug but I don't find anyway to do it on the remote device. In the application configuration I couldn't find anything about log level just this line:

Sure, log4cpp uses a log4cpp.properties file to configure the logger.

The path to this file will be passed to log4pp::PropertyConfigurator::configure()

when you configure your logger (usually at application startup); therefore, it could be stored anywhere in your filesystem, so you'll need to see what path is passed in to find the file.

A simple example properties file:

log4cpp.rootCategor=DEBUG, A1 log4cpp.main=INFO, A1

# A1 is to the console

log4cpp.appender.A1=org.apache.log4j.ConsoleAppender log4cpp.appender.A1.layout=PatternLayout log4cpp.appender.A1.ImmediateFlush=true log4cpp.appender.A1.layout.ConversionPattern=Console %d [%t] %-5p %c - %m%n

It's fairly easy to use a stringstream. You can then convert it to std::string using str().
