Hi Steven, While porting those two patches from linux to trace-cmd tree: [PATCH 3/9] tools/lib/traceevent: Install trace-seq.h API header file [PATCH 2/9] tools/lib/traceevent: Added support for pkg-config I noticed a mismatch between linux and trace-cmd in logic installing library header files, in main Makefile: linux code installs library headers in "$(prefix)/include/traceevent" trace-cmd code nstalls library headers in "$(prefix)/include/trace-cmd" This is the destination install path of traceevent library header files: event-parse.h, event-utils.h, trace-seq.h, kbuffer.h We should make it consistent, what install folder to choose for those files ? -- Tzvetomir (Ceco) Stoyanov VMware Open Source Technology Center
