Thanks for your quick reply.
I am sending proposed changes here.
Does anyone know how to modify 'configure.in' for this problem?
1) Drop from aclocal.m4 definition of function LOC_CHECK_VERSION
and put the two following functions instead.
*******************************
AC_DEFUN(LOC_CHECK_VERSION_STRING,[
AC_MSG_CHECKING($3 version)
ac_save_cppflags="$CPPFLAGS"
CPPFLAGS="$5 $CPPFLAGS"
AC_TRY_RUN([
#include <stdio.h>
#include <$1>
int main(void) {
FILE *fp = fopen("conftestdata","w");
fputs($2, fp);
return 0;
}
],
[ $4=`cat conftestdata`
AC_MSG_RESULT($$4)],
[ AC_MSG_ERROR([*** Could not determine $3 version.]) ],
[ $4=$6
AC_MSG_RESULT([unknown (cross-compiling)]) ])
CPPFLAGS=$ac_save_cppflags
])
AC_DEFUN(LOC_CHECK_VERSION_NUMBER,[
AC_MSG_CHECKING($3 version)
ac_save_cppflags="$CPPFLAGS"
CPPFLAGS="$5 $CPPFLAGS"
AC_TRY_RUN([
#include <stdio.h>
#include <$1>
int main(void) {
FILE *fp = fopen("conftestdata","w");
fprintf(fp, "%d", $2);
return 0;
}
],
[ $4=`cat conftestdata`
AC_MSG_RESULT($$4)],
[ AC_MSG_ERROR([*** Could not determine $3 version.]) ],
[ $4=$6
AC_MSG_RESULT([unknown (cross-compiling)]) ])
CPPFLAGS=$ac_save_cppflags
])
******************************************
2) in configure.in
use LOC_CHECK_VERSION_STRING for checking of TCL_VERSION and TK_VERSION
use LOC_CHECK_VERSION_NUMBER for checking of PJ_VERSION
diff looks like:
