Profiling not working on v9.2.0 anymore #62

Closed Ilir-Liburn closed 1 year ago

Ilir-Liburn commented 1 year ago

Hello,

profiling worked last time I made a build (half year ago), now I get bunch of errors. I don't understand, what could cause this? I use TDM-GCC-32, but I switched to TDM-GCC-64 because profiling is totally unusable on 32bit version.

Plus, I get

../include/os_e.h:75:12: warning: '_putenv_s' redeclared without dllimport attribute: previous dllimport ignored [-Wattributes]

while using TDM-GCC-64 instead of TDM-GCC-32. But why (both are v9.2.0)?

Here is the profiling error:

Never mind, I switched back to old build only to realize that I forgot -fprofile-generate switch on shared library. Closing...
