Subject: Building setup.exe: conflicting declarations of ssize_t
Date: Sun, 04 Sep 2011 02:19:00 -0000	[thread overview]
Message-ID: <4E62E04D.9090109@cornell.edu> (raw)

Building setup.exe fails as follows:

depbase=`echo archive.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
        i686-pc-mingw32-g++ -DPACKAGE_NAME=\"setup\" -DPACKAGE_TARNAME=\"setup\" -DPACKAGE_VERSION=\"0\" -DPACKAGE_STRING=\"setup\ 0\" -DPACKAGE_BUGREPORT=\"xxx\" -DPACKAGE_URL=\"\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DLT_OBJDIR=\".libs/\" -DHAVE_LIBMINGW32=1 -DHAVE_ERRNO_H=1 -DHAVE_STRING=1 -DHAVE_STRING_H=1 -I.  -DLZMA_API_STATIC -I./libgetopt++/include  -Werror -Wall -Wno-uninitialized -Wpointer-arith -Wcomments -Wcast-align -Wwrite-strings -g -O2 -MT archive.o -MD -MP -MF $depbase.Tpo -c -o archive.o archive.cc &&\

io_stream.h:37:21: error: conflicting declaration ‘typedef long int ssize_t’
/usr/i686-pc-mingw32/sys-root/mingw/include/sys/types.h:118:18: error: ‘ssize_t’ has a previous declaration as ‘typedef _ssize_t ssize_t’

The conflicting declarations result from the following recent change to the mingw-runtime package:

2011-08-19  Chris Sutcliffe  <xxx>

	* include/sys/types.h (ssize_t): Defined as int as opposed to long.

The following patch enables the build to complete, but I don't know if it's the right way to fix this:

--- io_stream.h.orig    2009-12-18 06:59:54.000000000 -0500
+++ io_stream.h 2011-09-03 21:14:44.664235000 -0400

 //Where is this defined?
-#if defined(_WIN32) && ! defined(__CYGWIN__)
+#if defined(_WIN32) && ! defined(__CYGWIN__) && ! defined(HAVE_SYS_TYPES_H)
 typedef signed long ssize_t;
 #endif
