Re: [Oorexx-devel] Building ooRexx with Debug

2019-01-04 Thread Enrico Sorichetti via Oorexx-devel 
The build types as defined by CMAKE provide as a courtesy to the developer
A set of predefined flags for the compiler and the linker 

CMAKE_C_FLAGS=''
CMAKE_C_FLAGS_DEBUG='-g'
CMAKE_C_FLAGS_MINSIZEREL='-Os -DNDEBUG'
CMAKE_C_FLAGS_RELEASE='-O3 -DNDEBUG'
CMAKE_C_FLAGS_RELWITHDEBINFO='-O2 -g -DNDEBUG'

CMAKE_CXX_FLAGS=''
CMAKE_CXX_FLAGS_DEBUG='-g'
CMAKE_CXX_FLAGS_MINSIZEREL='-Os -DNDEBUG'
CMAKE_CXX_FLAGS_RELEASE='-O3 -DNDEBUG'
CMAKE_CXX_FLAGS_RELWITHDEBINFO='-O2 -g -DNDEBUG'

An equivalent set of flags are provided for the linker 

You are free to define Your own build types 
As long as You define the same set of flags with the last token set
To the build type name 

CMAKE does not check the build type, 
Specifying an unknown build type  implies that no specific flags will be 
provided 

Enrico

  
Ps 

Find attached a function that will dump all the known CMAKE variables
At time of invocation

It will help in finding out the values of little known variables

Just invoke it with 

vdump( ${CMAKE_CURRENT_LIST_FILE} "${CMAKE_CURRENT_LIST_LINE}” )

Re: [Oorexx-devel] Building ooRexx with Debug

2019-01-04 Thread P.O. Jonsson 
I think this is related to the question "Questions ad differences between 
"RELEASE", "DEBUG" and "RELWITHDEBUGINFO" on Windows?“ asked by Rony  4 Dec 
2018, It would be most welcome to have this clarified on all platforms (what 
switches and where do they interact with the build process).

I have tried to read cmakelists.txt for answers but does not get me any wiser 
:-(.
