I have lots of .c files and .h files and I want to compile all of them. But I find I must add every filename manually in tasks.json. Is there any way to link all the .c files in the same folder?
You must still have a make system for your project for instance a Makefile.
So you should create a build rule in your Makefile and the run make from tasks.json
Here is an example I have on github, it is for C++ but the concept is the same for C.

For a project in C, we used bazel build . We see that while updating files here and there some times we forget to remove dependent .h files while its easier to add dependencies its difficult to remove. Is there functionality from bazel or frm the compiler to indicate unnecessary dependencies.?
Thanks.
I am starting to learn about CMake and have two questions:
1. Do I need to update the CMakeLists.txt file every time When I add a new file?
Assuming that the size of the project grows, the number of subdirectories and source files in the project will also increased greatly.
In such a case, I guess it is inconvenient to update the CMakelists.txt file whenever a new file or directory is added to the project.
Or is it part of the code management? How is it usually done?
2. In order to build a C Eclipse project(makefile) using CMake, should I write the CMakeList.txt manually?
There are many ways to import CMake projects into Eclipse, but I can't see how to build a C Eclipse project with CMake.
Do I need to update the CMakeLists.txt file every time When I add a new file?
CMake, like GNU make, allows to use wildcards to specify source files.
However, it's good practice to explicitly list files to build, in order to avoid silly mistakes (due, for example, to missing or unexpected files in source directory).
When file list becomes large, build definition files (like CMakeLists.txt) may be split into multiple files.
In order to build a / C Eclipse project(makefile) / using CMake, Should I write CMakelist.txt manually?
I don't know aboud Eclipse, but many IDEs partially/completely automate CMakelists.txt creation. Maybe Eclipse has such a tool too.
Yes write your CMakeLists.txt manually. This can barely be automated, beside adding new header files. There is a way to include all *.h files, but it is not enouraged.
And add every new header file manually. C files are not needed. Adding header files should not happen ofen.
Writing your own CMakeLists.txt files is recommended (at least you understand how CMake works). However, for larger projects it makes sense to automate it. I decided to post my own CMake generator https://github.com/Aenteas/cmake-generator so anyone who wants to implement their customized version could adopt some ideas from here (as it is not likely that my generator would suit your needs perfectly).
I am using Windows 10 and Eclipse Mars edition 32 bit. Programming in C
I am trying to learn C from a Lynda.com course C Essential Training. The course provides a zipped directory with many .c and files and a few others like .h files as you can see below.
However in the video he managed to get each .c file and related source code into its own directory structure.
I've tried numerous type of imports and I also used a batch file to put each .c file in its own folder and tried importing that. I was able to get the Eclipse IDE project window to look like the instructors, but as soon as I tried to compile individual .c programs the project kept looking in the primary workspace folder which for me is C:\Source\Testing\workspace and error'd out.
Is there an import option to create this type of subdirectory structure automatically? I want to go through the tutorial and build and execute each .c file individually. However what I have had to do is put the .c file into a single folder build it and run it one at a time. I then have to delete the source and debug folder and start over for each lesson. There must be a better way.
Eclipse workspace is streigh connected to FS.
This means that your workspace in Eclipse is a folder on your hard disk or where it is stored.
What you can simply do is to create a new folder using right-click-popup-menu within Eclipse Project Explorer and then copy/move files into the new folder.
Or you can create a new folder into your workspace directory and copy/move file inside, then you must refresh Eclipse workspace.
I have a project written in C; it has up to six sub-directories with .mk files, a make directory, at least one makefile, and Android.mk files.
I have used Android Studio, ndk, and JNI to build a project which compiles and runs. Now I want to port the above project into it. I have read all the GNU make manual, and know that I can include other make files. My question is would it be better to use gradle to include the make files above, and can I even do it? I have not read the gradle manual yet. It is my understanding that it is a build environment; I am not clear on what are it's differences / similarities with make. And if I can use it to complement make or I just have to pick one and go with it. I did have to edit it to get the JNI project working. My initial goal is to just run the make files in the native project in silent i.e. have them not produce any .o files and see what they do and validate that I am including them; then I want to include all the .c files and build .o files. I know I can do this with include statements in make file and since I have an Android.mk file in my project, I think I can do it through that. But I wonder if in the long run it is better to use gradle. What should I do please?
I have an Eclipse project that I need to auto-generate some files before compiling it. I do not want to put this auto-generated files in my repository, so each time I compile the projetct I perform a pre-build to auto-generate this files.
The problem is that this auto-generated files are *.c and *.h files, and in the first time I compile the project, the following happens (in this order):
pre-build: auto-generate some *.c and *.h
build: eclipse will not build this auto-generated files
If I compile again, this files will be compiled. Maybe this is happening because of the discovery process of what files eclipse will compile. Before initing compilation, we do not have this auto-generated *.c and *.h files.
In the second time we compile, we already have this auto-generated files, so this files are compiled.
If you want full control over when exactly the custom build step takes place, which files need to be refreshed after it, the environment, the working directory etc.. do not specify it as a simple pre-build step. Go to the project properties -> Builders -> New... and choose "Program".
In the resulting dialog, you have much more control over the execution of your tool. For instance, you can make your tool run whenever the XML file is saved, and you can tell eclipse to refresh all the auto-generated files whenever it is run.
If I understand your question correctly, it seems that building your project the first time will auto-generate the necessary *.c and *.h source files, but the project will fail to fully build because these source files are not found immediately. After a small delay, Eclipse recognizes that there are new files added to the project and you can then build a second time and everything will proceed normally. Does that sound about right?
Assuming this is the case, my immediate thought is to write some sort of script or makefile so that all of these actions can take place in the proper order, with a single action. Depending on how dirty you want to get your hands, here's a link ;)
