Dan, It sounds like you are building for MinGW, and Cygwin is just a build environment. Is that what you want; native binaries produced using a normal build system? > A quick Google shows that a few other people have had this problem > trying to build Subversion with MinGW but it doesn't look like anyone's > resolved it. Does anyone know of a successful APR build with MinGW? Curt Arnold has successfully built it using Ant + cpptask as part of the log4cxx project. If you want to take a look, most of the problems have been addressed in this patch: http://zeroj.hda0.net/apr-win32-20050713.patch There may be win32 problems in these changes because the tests do not build using the libtool approach. Here is the log. $ make test (cd test && make check OSDIR=/d/workpits/apr-mingw/include/arch/win32 ) make[1]: Entering directory `/d/workpits/apr-mingw/test' /bin/sh ./libtool --silent --mode=compile gcc -g -O2 -DHAVE_CONFIG_H -I../include -I./../include -I/d/workpits/apr-mingw/include/arch/win32 -o testlockperf.lo -c testlockperf.c && touch testlockperf.lo /bin/sh ./libtool --silent --mode=link gcc -g -O2 -DHAVE_CONFIG_H -I../include -I./../include -I/d/workpits/apr-mingw/include/arch/win32 -no-install -Wl,--enable-auto-import,--subsystem,console -o testlockperf.exe testlockperf.lo ../libapr.la-lrpcrt4 -lws2_32 -ladvapi32 -lshell32 -lkernel32 -lmsvcrt fu01.o(.idata$3+0xc): undefined reference to `libmsvcrt_a_iname' fu02.o(.idata$3+0xc): undefined reference to `libmsvcrt_a_iname' fu03.o(.idata$3+0xc): undefined reference to `libmsvcrt_a_iname' fu04.o(.idata$3+0xc): undefined reference to `libmsvcrt_a_iname' fu05.o(.idata$3+0xc): undefined reference to `libmsvcrt_a_iname' fu06.o(.idata$3+0xc): more undefined references to `libmsvcrt_a_iname' follow nmth00.o(.idata$4+0x0): undefined reference to `_nm___pctype' make[1]: *** [testlockperf.exe] Error 1 make[1]: Leaving directory `/d/workpits/apr-mingw/test' make: *** [check] Error 2 I am working on removing the libtool dependance in order that a native dll is created and used. > Thanks, > Dan Cheers, John

Does anyone know of a successful APR build with MinGW? I feel like I remember a little discussion about this on this list at some point in the past, but basically what I'd ask is, simply, why use Cygwin? APR is by its nature designed to be its own portability layer -- you don't need the added portability layer of cygwin stacked on top of it. You can build APR natively on win32 with no trouble at all; we distribute visual studio projects with APR for this purpose. The upshot is that you can therefore build a native Subversion on win32 as well by using a native APR, since it's APR's job to do all the interfacing with the operating system.
RE: Building APR with Cygwin?
The problem is that I need to compile using MinGW under Cygwin, and MinGW doesn't provide any of the shared memory header files (shm.h, sys/mmap.h, sys/mman.h, etc.) so the test fails. A quick Google shows that a few other people have had this problem trying to build Subversion with MinGW but it doesn't look like anyone's resolved it. Does anyone know of a successful APR build with MinGW? Thanks, Dan Daniel M.

The relevant part of the log for each looks like this on Windows XP when I generate configure using an up to date Cygwin with `autoconf-2.5x' ... checking for shmdt... yes checking for shmctl... yes checking for create_area... no checking for MAP_ANON in sys/mman.h... yes checking for /dev/zero... yes checking for mmap that can map /dev/zero... yes decision on anonymous shared memory allocation method... 4.4BSD-style mmap() via MAP_ANON decision on namebased memory allocation method... SysV IPC shmget() ... I dont know a lot about Cygwin, but I would check that out first. What were the configure results for header sys/mman.h, function mmap, and function munmap? Cheers, John
