Hi, Camkes had been working fine till now. Suddenly, it stopped working. I am running it on x86 system (i7 processor), ubuntu 16.04 on qemu. I am running the following commands: mkdir build cd build ../init --plat pc99 --tut hello-camkes-2 --solution Following error is generated: --------------------------------------------------------------------------------------------------------------------------------- Traceback (most recent call last): File "../init", line 76, in <module> sys.exit(main()) File "../init", line 62, in main result = common.init_build_directory(args.plat, args.tut, args.solution, os.getcwd()) File "/home/goyal/sel4/camkes-tutorials-manifest/projects/sel4-tutorials/common.py", line 59, in init_build_directory result = sh.cmake(args + ['..'], _cwd = directory, _out=output) File "/usr/local/lib/python2.7/dist-packages/sh.py", line 1427, in __call__ return RunningCommand(cmd, call_args, stdin, stdout, stderr) File "/uTraceback (most recent call last): File "../init", line 76, in <module> sys.exit(main()) File "../init", line 62, in main result = common.init_build_directory(args.plat, args.tut, args.solution, os.getcwd()) File "/home/goyal/sel4/camkes-tutorials-manifest/projects/sel4-tutorials/common.py", line 59, in init_build_directory result = sh.cmake(args + ['..'], _cwd = directory, _out=output) File "/usr/local/lib/python2.7/dist-packages/sh.py", line 1427, in __call__ return RunningCommand(cmd, call_args, stdin, stdout, stderr) File "/usr/local/lib/python2.7/dist-packages/sh.py", line 774, in __init__ self.wait() File "/usr/local/lib/python2.7/dist-packages/sh.py", line 792, in wait self.handle_command_exit_code(exit_code) File "/usr/local/lib/python2.7/dist-packages/sh.py", line 815, in handle_command_exit_code raise exc sh.ErrorReturnCode_1: RAN: /usr/local/bin/cmake -DCMAKE_TOOLCHAIN_FILE=../kernel/gcc.cmake -G Ninja -DTUT_BOARD=pc -DTUT_ARCH=x86_64 -DTUTORIAL=hello-camkes-2 -DBUILD_SOLUTIONS=TRUE ..

Hi All, Somehow a file named CMakeCache.txt came into my top level directory. I removed that file and ran the init script. It is working fine now. Is this file created intentionally or is it some bug? -- Thanks and Regards, Amit Goyal On 2019-06-20 10:16, Aditya Upadhyay wrote:
Hello Amit, A CMakeCache.txt file can get accidentally created quite easily. I reproduced the issue by running "ccmake .." to pull up the interactive GUI in the top level directory instead of a build folder. chrisguikema@ubuntu ~/seL4/camkes-vm $ ls camkes_README.md CMakeLists.txt init-build.sh kernel projects README.md test tools CMake Error: The source directory "/home/chrisguikema/seL4/" does not appear to contain CMakeLists.txt. Specify --help for usage, or press the help button on the CMake GUI. chrisguikema@ubuntu ~/seL4/camkes-vm $ ls camkes_README.md CMakeFiles kernel README.md tools CMakeCache.txt CMakeLists.txt init-build.sh projects test The easiest solution is to just delete the file. It shouldn't just appear, except by mistake. -----Original Message----- From: Devel <devel-bounces@sel4.systems> On Behalf Of Amit Goyal Sent: Monday, June 24, 2019 3:05 PM To: Aditya Upadhyay <aadit0402@gmail.com> Cc: devel@sel4.systems Subject: Re: [seL4] CMake Error CAUTION: This email originated from outside the organization.

FWIW the CMake folk actually document this [0]. Having said that, it seems numerous CMake users find this behaviour surprising [1] and I can certainly attest to having tripped over it before.
