Make sure that you are certain when you use an AND statement. As in normal makefile syntax, a single logical recipe line can be split into multiple physical lines in the makefile by placing a backslash before each newline.If the condition is true, make reads the lines of the text-if-true as part of the makefile if the condition is false, make ignores those lines completely. I am using GNU make 3.81. The error in the makefile is the missing space after ifeq. However I look for better solutions that are more portable. You need to provide more context what you are trying to achieve. Make (or rather a Makefile) is a buildsystem it drives the compiler and other build tools to build your code.From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well. Makefile tricks. GNU make is an extremely powerful program, and can be used to automate the building and testing of software.

This suffers from the problem that there may not be such a list in a complex makefile, with multiple programs being built. Make utility and make files: Since it is tedious to recompile pieces of a program when something changes, people often use the make utility instead.A make file should be named either Makefile (first letter uppercase) or makefile (all lowercase). A Makefile defines a graph of rules for creating a target (or targets). Its purpose is to do the minimum amount of work needed to update a target to the most recent version of the source.Make will complain about multiple recipes for the same rule. Before you compile, you need to make sure that the correct .inc is used for the system that you are on. It is also common to have project settings in .inc files, when there are multiple sub-makefiles for a project (one per directory). Makefiles. Multiple Source Files (1). u Obviously, large programs are not going to be contained within single files.u Each module is compiled separately and they are linked to generate the executable file. Multiple Source Files (2). Make reads its instructions from text files. An initialization file is read first, followed by the makefile. The initialization file holds instructions for all makes and is used to customize the operation of Make. Make automatically reads the initialization file whenever it starts up. name path of makefile from --print-data-base output GNU Make - build only out-of-date file in directory GNU make - transform every prerequisite into target (implicitly) setting variable with eval in Makefile recipe make: .SECONDARY target breaks buld Makefile: converting multiple .dot files to These advanced features allow Makefiles to be generated for multiple platforms from a single project file.The conditions used in a given scope can also be negated to provide an alternative set of declarations that will be processed only if the original condition is false. I have a make argument that can have three values, say A, B and C. I wrote the following in makefileI found similar solutions in stack overflow, but nothing works for me. I am using GNU make 3.81. The error in the makefile is the missing space after ifeq.

If you type make and theres a file called Makefile, but no file called makefile, then it will run the commands from the first target of that file, provided the dependent files are more recent than the target.Sometimes, a makefile will be used to generate multiple executables. Moreover, the files in each directory (module) have their own makefile. To compile a program that contains multiple makefiles, we need to write a main makefile that executes the makefiles for all the modules. So here is what I have in my .emacs file.
