Nouvel objet : gambc40b15 on WinXP MinGW/MSYS

14 Sep 2005


      I haven't tried --enable-shared with MinGW.  I assume without this  
flag the system compiles properly?
You can try removing the definition
#define ___CAN_IMPORT_EXPORTED
from include/gambit.h and see if that improves things.  You can also  
try defining some of the other ___CAN_IMPORT_... symbols.  All of  
this information should really be determined by the configure script,  
but that's not the case currently.

Attempting a build on WinXP using MinGW/MSYS I did
./configure --enable-shared --enable-single-host
  make
which got as far as generating lib/libgambc.dll
Then in the gsi link step
gcc  _gsi.o _gsi_.o -L../lib -lgambc -lws2_32 -o gsi.exe
there were lots of linker (auto-import) warnings, below, and finally
_gsi.o(.text+0x194b):_gsi.c: variable '___G_main' can't be auto- 
imported. Please read the documentation for ld's --enable-auto- 
import for details.
  collect2: ld returned 1 exit status
  make[1]: *** [gsi.exe] Error 1
I also note that I think the link of gsi is trying with with -lgambc
to reference libgamc.a which does not exist (lib/libgambc.dll was
build, not lib/libgamc.a). The -l option doesn't look for DLLs, does
it? Though when I tried
gcc  _gsi.o _gsi_.o ../lib/libgambc.dll -lws2_32 -o gsi.exe
I got the same error
_gsi.o(.text+0x194b):_gsi.c: variable '___G_main' can't be auto- 
imported. Please read the documentation for ld's --enable-auto- 
import for details.
