      Description

      Building current released subversion (1.9.x, 1.10.x, 1.11.x) or 1.12.0 RC1 against apr-1.7.0 will fail configure with

       

      [...]
      configure: Configuring python swig binding
      checking for Python includes... (cached) -I$(PYTHON_INCLUDEDIR)
      checking for compiling Python extensions... x86_64-pc-linux-gnu-gcc -pthread -fPIC
      checking for linking Python extensions... x86_64-pc-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,--as-needed -L.
      checking for linking Python libraries... -Wl,-O1 -Wl,--as-needed -L.
      checking for apr_int64_t Python/C API format string...
      configure: error: failed to recognize APR_INT64_T_FMT on this platform
      

      I tried to debug the problem. The conftest.c file is

       

       

      [...]
      /* end confdefs.h.  */
      #include <apr.h>
                           MaTcHtHiS APR_INT64_T_FMT EnDeNd
      

      and the test will validate the output of

       

      gcc -E -DLINUX -D_REENTRANT -D_GNU_SOURCE -I/usr/include/apr-1 conftest.c

      against one of the following regular expressions

       

      /bin/grep -E 'MaTcHtHiS +"lld" +EnDeNd'
      /bin/grep -E 'MaTcHtHiS +"ld" +EnDeNd'
      /bin/grep -E 'MaTcHtHiS +"d" +EnDeNd'

      However, the output of the command has changed between 1.6.5 - 1.7.0:

      > +                                               EnDeNd
      

      So there's no match anymore.

       

      Check is coming from build/ac-macros/swig.m4.

      Additional note:

      You will hit this error even if you try to configure with --without-swig.
