> Converting this to an out-of-source build might be tricky,
I beg to disagree …
No more tricky than the same for somebody who wants to build a rexx external
function
And would like to detect automatically the proper compiler and linker flags
for the unix like environments
the thing is automated by using pkgconf/pkg-config ( present in all the linux
installations )
And having ooRexx build the proper oorexx.pc
As it would be a courtesy just build it straight away
… not difficult at all to do
Or … less elegant
In the CMakeLists parse the output of the command “which rexx”
And if the oorexx installation respect the STANDARD unix structure (bin,
include,lib)
It will be easy to determine the proper flags
E
Here is a sample snippet
set( _lc_all "$ENV{LC_ALL}" )
set( ENV{LC_ALL} "C" )
execute_process( COMMAND which rexx
WORKING_DIRECTORY ${CMAKE_BINARY_DIR}
RESULT_VARIABLE _res
ERROR_VARIABLE _err
OUTPUT_VARIABLE OOREXXPATH
OUTPUT_STRIP_TRAILING_WHITESPACE )
set( ENV{LC_ALL} "${_lc_all}" )
message( "@@ RESULT '${_res}' " )
message( "@@ RESULT '${_err}' ")
message( "@@ RESULT '${OOREXXPATH}' " )
if( NOT "${_res}" STREQUAL "0" )
message( FATAL_ERROR "
Open Object Rexx is not installed" )
endif()
get_filename_component( OOREXXHOME "${OOREXXPATH}" REALPATH )
message( "@@ Include flag '-I${OOREXXHOME}/include'" )
message( "@@ Library flag '-I${OOREXXHOME}/lib'" )
Which when used in the CmakeLists gives ( when rexx is found )
@@ RESULT '0'
@@ RESULT ''
@@ RESULT '/opt/ooRexx_Alt/bin/rexx'
@@ Include flag '-I/opt/ooRexx_Alt/bin/rexx/include'
@@ Library flag '-I/opt/ooRexx_Alt/bin/rexx/lib'
And when not found …
@@ RESULT '1'
@@ RESULT ''
