Don't know why this would happen, but these are defined in
external_y.c. You may try to remove HAVE_SOCKETS config.h and then
remove the references to external_l/external_y in the makefile.am. But
remember that config.h gets clobbered next time you run configure.
Edit configure.in to get rid of HAVE_SOCKETS forever.
I looked over the compilation command again and noticed that there is no
file external_y.o. So this leads to my original error.
gnubg.o:gnubg.c:(.text+0x7b6d): undefined reference to `_CreateMutex'
You can probably just comment out the line in gnubg.c where it says CreateMute
That helped, thanks.
Finally I sorted out the problem. To compile external_y.y I moved
definitions of cmdtype and extcmd from external.h to external_y.y.
typedef enum _cmdtype {
COMMAND_NONE = 0,
COMMAND_FIBSBOARD = 1,
COMMAND_EVALUATION = 2
} cmdtype;
typedef struct _extcmd {
cmdtype ct;
/* evalcontext */
int nPlies;
float rNoise;
int fDeterministic;
int fCubeful;
int nReduced;
int fUsePrune;
/* fibs board */
char *szFIBSBoard;
} extcmd;
For some reason they seemed to be undefined for compiler from external.h.
One more note. Files board3d/drawboard3d.c and board3d/misc3d.c include
file wglBuffer.h.
The include is done inside #ifdef WIN32 condition directives as
#include "wglbuffer.h"
Since I make cross-compilation in Linux environment file names are
case-sensitive. So it is preferable to have "wglBuffer.h" instead of
"wglbuffer.h".
