[CentOS] Fwd: Cross Building Tcl using Mingw32-gcc (4.9.2)
I posted this to the comp.lang.tcl newsgroup, but it might relate to a
possible bug in the Mingw32 cross-build environment under CentOS 6 (or EPEL).

I am trying to cross-build Tcl (8.5.8) and I have encounted two problems:
One I easily hacked the sources (wrapped the offending lines with #ifdefs):
./../generic/tclPosixStr.c:347:5: error: duplicate case value
case EPFNOSUPPORT: return "EPFNOSUPPORT";
^
./../generic/tclPosixStr.c:290:5: error: previously used here
case ENOPROTOOPT: return "ENOPROTOOPT";
^
./../generic/tclPosixStr.c: In function 'Tcl_ErrnoMsg':
./../generic/tclPosixStr.c:795:5: error: duplicate case value
case EPFNOSUPPORT: return "protocol family not supported";
^
./../generic/tclPosixStr.c:738:5: error: previously used here
case ENOPROTOOPT: return "bad protocol option";
^
The other I am not sure how to fix:
i686-w64-mingw32-gcc -c -O2 -fomit-frame-pointer -Wall
-I"../../generic" -DTCL_TOMMATH -DMP_PREC=4

^
Is there a solution possible? This looks like internal inconsistency with the
header files that are part of the build toolchain.

I installed the i686-w64-mingw32 packages on a Ubuntu 12.04 VM and had no problems cross building Tcl 8.5.8.> > Forwarded Message: > > From: Robert Heller <heller at deepsoft.com> > Subject: Cross Building Tcl using Mingw32-gcc (4.9.2) > Newsgroups: comp.lang.tcl > Message-ID: <Nc-dnd1wRNTsy6PInZ2dnUU7-b-dnZ2d at giganews.com> > Date: Mon, 27 Apr 2015 10:32:01 -0500 > > > I am trying to cross-build Tcl (8.5.8) and I have encounted two problems: > > One I easily hacked the sources (wrapped the offending lines with #ifdefs): > > ./../generic/tclPosixStr.c:347:5: error: duplicate case value > case EPFNOSUPPORT: return "EPFNOSUPPORT"; > ^ > ./../generic/tclPosixStr.c:290:5: error: previously used here > case ENOPROTOOPT: return "ENOPROTOOPT"; > ^ > ./../generic/tclPosixStr.c: In function 'Tcl_ErrnoMsg': > ./../generic/tclPosixStr.c:795:5: error: duplicate case value > case EPFNOSUPPORT: return "protocol family not supported"; > ^ > ./../generic/tclPosixStr.c:738:5: error: previously used here > case ENOPROTOOPT: return "bad protocol option"; > ^ > > The other I am not sure how to fix: > > i686-w64-mingw32-gcc -c -O2 -fomit-frame-pointer -Wall -I"../../generic" -DTCL_TOMMATH -DMP_PREC=4 -I"../../libtommath" -I".." -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DSTDC_HEADERS=1 -DHAVE_NO_SEH=1 -DHAVE_NO_LPFN_DECLS=1 -DHAVE_ALLOCA_GCC_INLINE=1 -DHAVE_CAST_TO_UNION=1 -DTCL_CFGVAL_ENCODING=\"cp1252\" -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 -DTCL_CFG_OPTIMIZED=1 -DTCL_CFG_DEBUG=1 -DBUILD_tcl "../tclWin32Dll.c" -o tclWin32Dll.o > ./tclWin32Dll.c:65:3: error: conflicting types for 'EXCEPTION_REGISTRATION' > } EXCEPTION_REGISTRATION; > ^ > In file included from /usr/i686-w64-mingw32/sys-root/mingw/include/minwindef.h:146:0, > from /usr/i686-w64-mingw32/sys-root/mingw/include/windef.h:8, > from /usr/i686-w64-mingw32/sys-root/mingw/include/windows.h:69, > from ../tclWinPort.h:72, > from ../../generic/tclPort.h:25, > from ../../generic/tclInt.h:3946, > from ../tclWinInt.h:17, > from ../tclWin32Dll.c:16: > /usr/i686-w64-mingw32/sys-root/mingw/include/winnt.h:3554:43: note: previous declaration of 'EXCEPTION_REGISTRATION' was here > typedef EXCEPTION_REGISTRATION_RECORD EXCEPTION_REGISTRATION; > ^ > > Is there a solution possible?
