   Is there an existing issue for this?

   • I have searched the existing issues

   Current behaviour

   When following Compiling for Test Coverage instructions: doc/developer-notes-CompilingForTestCoverage

   I encounter error:

   0CMake Error: File /home/alicebob/wkspc1/presets/bitcoin/cmake/cov_tool_wrapper.sh.in does not exist.
   1CMake Error at /home/alicebob/wkspc1/build/bitcoin/CoverageInclude.cmake:14 (configure_file):
   2  configure_file Problem configuring file
   3Call Stack (most recent call first):
   4  /home/alicebob/wkspc1/build/bitcoin/Coverage.cmake:5 (include)
   

   Expected behaviour

   Driver for functional tests should run, generating instrumentation report HTML.

   Steps to reproduce

   1. Compile for coverage. Following are sample cmake cache variables for the CLang tool chain:

   0"CMAKE_C_COMPILER": "clang",
   1"CMAKE_CXX_COMPILER": "clang++",
   2"CMAKE_CXX_FLAGS": "-fprofile-arcs -ftest-coverage",
   3"CMAKE_BUILD_TYPE": "Coverage",
   

   2. Follow instructions in developer notes to compile for coverage: doc/developer-notes-CompilingForTestCoverage

   Relevant log output

   CMake Error: File /home/alicebob/wkspc1/presets/bitcoin/cmake/cov_tool_wrapper.sh.in does not exist.
   CMake Error at /home/alicebob/wkspc1/build/bitcoin/CoverageInclude.cmake:14 (configure_file):

   I cannot reproduce this error on Ubuntu 24.10. UPD. See #31638 (comment). @jimhashhq

   Could you provide the exact command-line steps required to reproduce the issue?

   if you are using an IDE, please provide more details about the IDE, its configuration, and the steps you followed to encounter this problem.

   What version of CMake are you using?

   I am not sure if clang coverage works out of the box right now with "CMAKE_BUILD_TYPE": "Coverage",.

   You’ll have to use the “normal” build type and manually pass all required flags to clang, or patch the cmakelists txt.

   Duplicate of #31047?

   The error is reproducible when invoking cmake -P <path-to>/Coverage.cmake from a directory other than the repository root.

   In the following code:https://github.com/bitcoin/bitcoin/blob/5acf12bafeb126f2190b3f401f95199e0eea90c9/cmake/script/CoverageInclude.cmake.in#L14-L20 cmake/cov_tool_wrapper.sh.in is a relative path and resolved based on the current working directory. That happens to work when following the Developer Notes literally.

   I’ll submit a fix shortly.
