• Component: Tools / Tests
• Status: RESOLVED FIXED

[Adrian Perez]

It's basically impossible to know at a glance what the actual
problem is with the current error output:

Patch


With this patch; when the same error situation as above is reached,
the following is logged:

Exception: pkg-config produced a non-zero return code 1                                                        
Command:                                                                                                                           
  pkg-config /home/aperez/wpe/WebKit/build-rc/wpe-web-extension-0.1.pc --cflags                                                                            
Error output:                                                      
  Package wpe-0.2 was not found in the pkg-config search path.
  Perhaps you should add the directory containing 'wpe-0.2.pc'
  to the PKG_CONFIG_PATH environment variable                     
  Package 'wpe-0.2', required by 'wpe-web-extension-0.1', not found

FWIW, the failure from the WPE EWS seems unrelated — it needed
cleaning of the build directory because the CMake cache was botched
after r243060.
