in thread perl 5.14.0-RC1 is available for testing!

perl.exe/perl514.dll needs libgcc_s_dw2-1.dll, but op/taint modifies $ENV{PATH} so when it uses $Invoke_Perl, it can't find libgcc_s_dw2-1.dll

This section of makefile.mk is supposed to deal with that issue: 
#
# If building with gcc-4.x.x (or x86_64-w64-mingw32-gcc-4.x.x), then
# uncomment  the following assignment to GCC_4XX, make sure that CCHOM
+E
# has been set correctly above, and uncomment the appropriate
# GCCHELPERDLL line.
# The name of the dll can change, depending upon which vendor has supp
+lied
# your 4.x.x compiler, and upon the values of "x".
# (The dll will be in your mingw/bin folder, so check there if you're
# unsure about the correct name.)
# Without these corrections, the op/taint.t test script will fail.
#
#GCC_4XX        *= define
#GCCHELPERDLL    *= $(CCHOME)\bin\libgcc_s_sjlj-1.dll
#GCCHELPERDLL    *= $(CCHOME)\bin\libgcc_s_dw2-1.dll
#GCCHELPERDLL    *= $(CCHOME)\bin\libgcc_s_1.dll

Not sure how that fits in with your method of building. I've only ever built perl with gcc by running dmake -f makefile.mk

With my mingw port of gcc-3.4.5 I'm finding that porting/buildtoc.t fails test 2. All other tests pass.
With my mingw64 port of gcc-4.6.0, I'm finding that the tests hang when 19_CPANPLUS-Dist.t is run, so I don't get to find out what failures there are.

    AHA, typical dumb makefile and I forgot to grep :)

    That makefile is really really unreadable (someone should indent it, rewrite it)

    I shouldn't need to know anything about this :) The GCC_4XX way should be automatic one way or another, something like 

    .IF "$(CCTYPE)" == "GCC"
    GCC_VERSION *= $(shell gcc -dumpversion)
    GCC_MAJOR_VERSION *= $(GCC_VERSION:b:b)
    .IF  "$(GCC_MAJOR_VERSION)" == "4"
        GCC_4XX *= define
    .ENDIF
.ENDIF

    [download]
    Or my way (untested) 
    .IF "$(CCTYPE)" == "GCC"
    GCC_VERSION *= $(shell gcc -dumpversion)
    GCC_MAJOR_VERSION *= $(GCC_VERSION:b:b)
    .IF  "$(GCC_MAJOR_VERSION)" == "4"
        CFLAGS +=-static-libgcc
        LIBC   += -static-libgcc 
    .ENDIF
.ENDIF

    [download]
    Checking my make commands, a test makefile.mk 
    CCTYPE        *= GCC
.IF "$(CCTYPE)" == "GCC"
    GCC_VERSION *= $(shell gcc -dumpversion)
    GCC_MAJOR_VERSION *= $(GCC_VERSION:b:b)
    .IF  "$(GCC_MAJOR_VERSION)" == "4"
    CFLAGS        += -static-libgcc 
    LIBC        += -static-libgcc 
    GCC_4XX        *= define
    .ENDIF
.ENDIF

__echo_GCC:
    @echo GCC_VERSION   $(GCC_VERSION)
    @echo GCC_MAJOR_VERSION   $(GCC_MAJOR_VERSION)
    @echo GCC_4XX  $(GCC_4XX)
    @echo CFLAGS  $(CFLAGS)
    @echo LIBC  $(LIBC)
    $(NOOP)

    how it runs (output) 
    $ dmake -f makefile.mk
dmake: Executing shell macro: gcc -dumpversion
dmake: Executing shell macro: gcc -dumpversion
GCC_VERSION   4.5.2
dmake: Executing shell macro: gcc -dumpversion
GCC_MAJOR_VERSION   4
GCC_4XX  define
CFLAGS  -static-libgcc
LIBC  -static-libgcc

    Yup, thats what I do, the -f makefile.mk isn't mandatory since that is the default

      You know, I wrote a little program to use objdump to find out what dlls are linked to perl.exe/perl514.dll , to copy them to t directory

      I tested it, it worked, and then I dawned me how stupid I find this :)

      The whole thing should be replaced with 

      .IF "$(CCTYPE)" == "GCC"
    $(XCOPY) $(CCHOME)\bin\* ..\t\$(NULL)
.ENDIF

      [download]
      Since the dll's in ..\t\ aren't used for anything else and they're deleted during dmake clean

      KISS

       If that works, it would be an improvement.
      One problem with it is that it's not guaranteed that the C compiler is called 'gcc'. With the mingw64 compiler that I use it's called 'x86_64-w64-mingw32-gcc' - and  gcc -dumpversion would simply return something like 'gcc' is not recognized as an internal or external command, operable program or batch file.

      I guess, however, there might also be a way to cater for that possibility.

        FWIW the actual compiler name is supposed to be in $(CC), CCTYPE is configuration variable
        Read more... ack \bCC\b makefile.mk (680 Bytes)
        I now prefer this.
