Question

I cannot seem to build perl 5.6.2 in Cygwin 1.7.11.

Here are the steps I am following to do it so far.

Download perl 5.6.2 source from website and untar to some folder “perl-5.6.2”

cd perl-5.6.2/bld
sh ../Configure -des -Dmksymlinks -Dprefix=/common/ndd/perl/5.6.2 -DDEBUGGING 2>&1
make 2>&1
make install 2>&1

Here are the logs from this:

What happens is make creates “perl-5.6.2/bld/perl.exe” and this file generates an abort signal every time.

Here is the backtrace from running gdb on it. (Note: I configured with -DDEBUGGING so all the gcc debug flags should be enabled.)

(gdb) run
Starting program: /openlogic/build/work/perl-5.6.2/bld/perl.exe
[New Thread 3348.0xf54]
[New Thread 3348.0x48c]

Program received signal SIGABRT, Aborted.
0x00000000 in ?? ()
(gdb) backtrace

#3  0x000000a8 in ?? ()
#4  0x00000000 in ?? ()
(gdb) quit

Here id the ldd.exe command ran on perl.exe

$ ldd /ndipiazza/build/work/perl-5.6.2/bld/perl.exe
        ntdll.dll => /cygdrive/c/Windows/SysWOW64/ntdll.dll (0x77910000)

        KERNELBASE.dll => /cygdrive/c/Windows/syswow64/KERNELBASE.dll (0x757e0000)
        libperl5_6_2.dll => /ndipiazza/build/work/perl-5.6.2/bld/libperl5_6_2.dll (0x66140000)
        cygcrypt-0.dll => /usr/bin/cygcrypt-0.dll (0x67db0000)
        cygwin1.dll => /usr/bin/cygwin1.dll (0x61000000)
        ??? => ??? (0x570000)

Can anyone see why I would be getting this sigabrt?

Answer 1

I figured it out. Perl 5.6.2 tries to use it’s own malloc. This is incompatible with Cygwin’s malloc.

I was given some help on Cygwin mailing list to fix this: http://cygwin.com/ml/cygwin/2012-07/msg00380.html

Bottom line, add -Dusemymalloc=n to the sh ./Configure arguments.

Then it works.
