The problem I'm having is that I'm trying to add a custom package for buildroot to compile and add to a finished image. It was simple to get the selection box show up for my sample project in menuconfig, but buildroot never seems to compile my code and install it. I created a simple program, a hello world kind of thing, including a Makefile. The program compiles and runs properly if I run "make" manually from the directory and run the executable. I've created the Config.in and .mk files according to the buildroot documentation online or so I think. My environment is a x86_64 host cross compiling for x86. Buildroot is 2013.05. Toolchain is Sourcery CodeBench 2012.09. Everything else in buildroot appears to build properly as I've had the produced image loaded and running on the target device and it works fine. It just lacks my simple program I'm guessing the issue is with my hello.mk so below is that file. Can anyone point me in a direction of what I might be doing wrong? Thanks much!

What is the name of the config option that you added, and are you sure it's enabled in .config? What happens if you explicitly run 'make hello' ? Depending on what you did before, you may also need to clear previous attempts from the output, for example with: make hello-dirclean If the hello package is seen correctly by buildroot, but the compilation doesn't work correctly, you may want to add KBUILD_VERBOSE=1 to the make command, to see the actual make command executed.

After some digging around, I found that buildroot wasn't even trying to grab or compile my code. What I discovered earlier today is that the variable names that I was using contained too many underscores. My Config.in and hello.mk files were using variables set as BR2_PACKAGE_COMPANY_PROJECT_HELLO. When I shortened it to just BR2_PACKAGE_HELLO then it started working properly. Apparently the additional underscores confused some parsing of the buildroot and/or Kbuild system. If that was mentioned in the documentation then I missed it. Maybe it was assumed. In any case, it's working now. Thanks for your help on this. I appreciate it. Best, Ryan Wilkins ^ permalink raw reply [flat|nested] 8+ messages in thread

Config.in had BR2_PACKAGE_COMPANY_PROJECT_HELLO which changed to BR2_PACKAGE_HELLO. hello.mk had COMPANY_PROJECT_HELLO_ variable names prefix which changed to HELLO_. That solved the issues.

Buildroot indeed expects BR2_PACKAGE_<packagename> in the Config.in files, and <packagename>_... for the .mk files. I also couldn't find this restriction explicitly mentioned in the documentation, it's only implicitly shown in the examples.

Actually it's already in the documentation: http://buildroot.org/downloads/manual/manual.html#package-name-variable-relation Anyway, you're more than welcome to submit patch for the doc ;-), to make this point more obvious, or any other things you've found uncovered in the manual.

In fact, as I read it, it seems to promote the use of the variables as I had tried and failed to use them. I haven't submitted patches for documentation in the past so I'll have to research it and then type something up to submit. Thanks for pointing out the section.
