For testing purposes, I'd like to build without large-address awareness.
What's the right way to do that? I tried
LDFLAGS=-Wl,--no-large-address-aware
and
LDFLAGS=-Wl,--disable-large-address-aware
but both resulted in "unrecognized option" errors from ld.
You specify --large-address-aware if you want it and don't specify if
you don't want it.
Sorry, I should have explained more clearly what the issue is. Cygwin's
gcc specifies --large-address-aware by default:
$ gcc -dumpspecs | grep large
%{mwindows:--subsystem windows} %{mconsole:--subsystem console}
%{!mno-cygwin:%{!mno-use-libstdc-wrappers: --wrap _Znwj --wrap _Znaj
--wrap _ZdlPv --wrap _ZdaPv --wrap _ZnwjRKSt9nothrow_t --wrap
_ZnajRKSt9nothrow_t --wrap _ZdlPvRKSt9nothrow_t --wrap
_ZdaPvRKSt9nothrow_t }} %{shared: %{mdll: %eshared and mdll are not
compatible}} %{shared: --shared} %{mdll:--dll} %{static:-Bstatic}
%{!static:-Bdynamic} %{shared|mdll: --enable-auto-image-base -e
%{mno-cygwin:_DllMainCRTStartup@12}
%{!mno-cygwin:__cygwin_dll_entry@12}}
%{!mno-cygwin:--dll-search-prefix=cyg %{!shared: %{!mdll:
--large-address-aware --tsaware}}}
I'm trying to override this default.
You're right that there isn't a way to disable --large-address-aware
but, since it's part of the specs, I'm not sure what would take
precedence if there was a --disable* option.
You could try using the above to create your own spec file and use
that on the command line for gcc, cumbersome as it is.
Reading the specs snippet --large-address-aware is only used if
-shared and -mdll have *not* been specified, i.e. you are building
with -static specified.
No, you might just be building a .exe.
