#CMAKE PRINT SOFTWARE#
By adding support for this, I can essentially create a table of output which will greatly help me to optimize/improve/debug the CMake configuration for a very large software suite I am supporting. in this case, you must include CMakePrintHelpers. My example here is of course trivial, but in reality I'm dealing with many thousands of lines of configuration output, many of them are similar in sequence and it is much easier to see patterns in output when similar output messages (looping) are on a single line. Instead of using message, you can also use cmakeprintvariables to display variables. Output is designed for human consumption and. What I would like to know is if cmake has the possibility to stop just after the first reported error.Execute_process(COMMAND bash "-c" "echo -n Hello, World!")īut I am looking for a native, convenient option. Print extra find call information during the cmake run to standard error. The CMake command-line tool displays STATUS to TRACE messages on stdout with the message preceded by two hyphens and a space. Configuring incomplete, errors occurred! Perhaps it has not yet beenĬMake Error at CMakeLists.txt:4 (set_property): I get the output : CMake Error at CMakeLists.txt:3 (set_property): Set_property(TARGET bar PROPERTY PROP2 TRUE)Īnd when i run cmake. Set_property(TARGET foo PROPERTY PROP1 TRUE) CMake printing search paths Adolfo Rodríguez dofo79 at Fri Feb 27 03:14. My file CMakeLists.txt: cmake_minimum_required(VERSION 3.6) The list of targets can be used for something else.
My use case was to generate an installation option for each target automatically. After using addexecutable () or addlibrary (), use that macro to insert the target in the list.
Inside a cmake module, define a property to contain the list of targets. Here is an example (this is not my real project, this is specifically designed to generate errors). It is more intrusive, but somewhat simple. on Linux the generation of the Makefiles). The time honored method of print statements looks like this in CMake. Do not list the output in more than one independent target that may build in parallel or the instances of the rule may conflict.

Is there any option, variable or means to stop CMake just after the first error?Ĭlarification: I'm not trying to stop the compilation of source code but the CMake generation (e.g. First, lets look at ways to debug a CMakeLists or other CMake file. A target created in the same directory ( CMakeLists.txt file) that specifies any output of the custom command as a source file is given a rule to generate the file using the command at build time. It is only at the end of the treatment that we learn that there is an error, so we have to go back up the whole log to see where it is located. If clang > 9 is an option, the ClangBuildAnalyzer produces a nice summary.

My goal was to simply get the time the compiler took to compile one of the targets, so I can print it on the comandline. It uses an open-source fork of CMake that supports stepping through CMakeLists.txt files, setting code/data breakpoints, evaluating/changing variables, etc. Choose from our vast catalog of 342 premium products.
