Bug 759058 – dev-db/mysql-connector-c-8.0.22 fails to build if CFLAGS or CXXFLAGS are empty

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Igor Franchuk 2020-12-08 14:41:22 UTC]

mysql-connector fails to build if either CFLAGS or CXXFLAGS are unset in a misleading way throwing 
CMake Error at CMakeLists.txt:879 (STRING):
  STRING sub-command REGEX, mode REPLACE needs at least 6 arguments total to
  command.
CMake Error at CMakeLists.txt:881 (STRING):
  STRING sub-command REGEX, mode REPLACE needs at least 6 arguments total to
  command.


Reproducible: Always




I suggest to add a direct check weather CFLAGS/CXXFLAGS are empty before proceeding with configure and if they are - throw a meaningful message like CFLAGS are empty, please configure CFLAGS/CXXFLAGS

I can confirm this REGEX problem with arm64, more specifically with 8.0.32-r1 ebuild. I fixed it by replacing 

  STRING(REGEX REPLACE "-specs=/usr/lib/rpm/redhat/.*"  ""
    CMAKE_C_FLAGS ${CMAKE_C_FLAGS})
  STRING(REGEX REPLACE "-specs=/usr/lib/rpm/redhat/.*"  ""
    CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS})

with 

  STRING(REGEX REPLACE "-specs=/usr/lib/rpm/redhat/.*"  ""
    CMAKE_C_FLAGS "${CMAKE_C_FLAGS}")
  STRING(REGEX REPLACE "-specs=/usr/lib/rpm/redhat/.*"  ""
    CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}")

Please note the added "". I hope someone benefit from this. Seeya.
