Thanks Wolfram, I tried patch #2 but CMake complains with an error message I'm apparently too dumb to understand:
-- Qt version: 5.12.3 -- Looking for backtrace -- Looking for backtrace - found -- backtrace facility detected in default set of libraries -- Found Backtrace: /usr/include CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:146 (message): Could NOT find Boost (missing: stacktrace_backtrace) (found suitable version "1.71.0", minimum required is "1.65.1") Call Stack (most recent call first): /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE) /usr/share/cmake/Modules/FindBoost.cmake:2179 (find_package_handle_standard_args) CMakeLists.txt:134 (find_package) -- Configuring incomplete, errors occurred! ...so... uh... why is it complaining even though it found a more recent version? Any idea? -Soeren On Fri, 2020-04-17 at 15:43 +0200, Wolfram Sang wrote: > Here is the second try to have stacktrace support in Pulseview > complete. > > Changes since v1: > * HACK crashes now when you press "Run" in pv, so you can view logs > before > * added check if 'backtrace' is supported on the system > * depending on that, the backtrace tracer or the simple tracer is > used > * no hardcoded libs anymore, all replaced by variables > * enforcing the debug build was removed.
