After that eNpc should read your old rebar.config `port_specs` and `port_env` settings as expected (it is rebar2's port compiler after all...). |
|
|
|
|
|
|
|
%% Supported configuration variables: |
|
|
|
%% |
|
|
|
%% * port_specs - Erlang list of tuples of the forms |
|
|
|
%% {ArchRegex, TargetFile, Sources, Options} |
|
|
|
%% {ArchRegex, TargetFile, Sources} |
|
|

%% {TargetFile, Sources} |
|
|
|
%% |
|
|
|
%% Note that if you want to use any of the rebar3 variables |
|
|
|
%% below you must MUST use a ${}-style to get the expansion |
|
|
|
%% to work. e.g. to expand REBAR_DEPS_DIR, do something like: |
|
|
|
%% |
|
|
|
%% {port_specs, [{"priv/nif.so", |
|
|
|
%% ["c_src/nif.c", |
|
|
|
%% "${REBAR_DEPS_DIR}/foo/bar.c"]}]}. |
|
|
|
%% |
|
|
|
%% This is a _very_ good way to be able to use your code both |
|
|
|
%% as a top level app and a dependency. |
|
|
|
%% |
|
|
|
%% CAVEAT! Not using {} is broken for the moment. |
|
|
|
%% |
|
|
|
%% * port_env - Erlang list of key/value pairs which will control |
|
|
|
%% the environment when running the compiler and linker. |
|
|
|
%% Variables set in the surrounding system shell are taken |
|
|
|
%% into consideration when expanding port_env. Note that |
|
|
|
%% for ERL_LDFLAGS, -lerl_interface is used for only those |
|
|
|
%% Erlang/OTP versions where it exists (those prior to |
|
|
|
%% version 23.0). |
|
|
|
%% |

|
|
|
%% CC - C compiler |

%% CXX - C++ compiler |

%% CFLAGS - C compiler |
|

%% LDFLAGS - Link flags |
|
|
|
%% ERL_CFLAGS - default -I paths for erts and ei |
|
|
|
%% ERL_LDFLAGS - default -L and -lerl_interface -lei |
|
|
|
%% DRV_CFLAGS - flags that will be used for compiling |
|
|
|
%% DRV_LDFLAGS - flags that will be used for linking |
|
|
|
%% EXE_CFLAGS - flags that will be used for compiling |
|
|
|
%% EXE_LDFLAGS - flags that will be used for linking |
|
|
|
%% ERL_EI_LIBDIR - ei library directory |
|
|
|
%% DRV_CXX_TEMPLATE - C++ command template |

|
%% DRV_CC_TEMPLATE - C command template |
|

%% Note that if you wish to extend (vs. replace) these variables, |
|

|
|
%% by specifying a triplet where the first string is a regex |

%% do: |
