Can't compile XS, getting "strcmp" error

MrNobo1024 has asked for the wisdom of the Perl Monks concerning the following question:

I've been experimenting with creating XS modules, but I can't get it to work. When I run nmake, it says
gcc -c -O1 -MD -DNDEBUG -DWIN32 -D_CONSOLE -DNO_STRICT -DHAVE_DES_FCR +YP T -DPERL_IMPLICIT_CONTEXT -DPERL_IMPLICIT_SYS -DPERL_MSVCRT_READFIX -O +1 -MD -DND EBUG -DVERSION=\"0.01\" -DXS_VERSION=\"0.01\" -IC:\PERL\lib\CORE + xstest.c xstest.c: In function `boot_xstest': xstest.c:37: incompatible type for argument 1 of `strcmp' NMAKE : fatal error U1077: 'GCC' : return code '0x1' Stop.
Is there any way to fix this problem? I'm using ActivePerl 5.6.1 and MinGW 2.95.2.

    Ensure that xstest.c at line 37 contains a call to strcmp where the first argument is a char*. It's rather self-explanatory. If you need additional help, you need to post the relevant piece of code.
    AgentM Systems nor Nasca Enterprises nor Bone::Easy nor Macperl is responsible for the comments made by AgentM. Remember, you can build any logical system with NOR.
      Actually xstest.c dosen't call strcmp at all. The relevant code is


      #include "EXTERN.h" #include "perl.h" #include "XSUB.h" MODULE = xstest PACKAGE = xstest void hello() CODE: printf("Hello, world!\n");
      /* * This file was generated automatically by xsubpp version 1.9508 from + the * contents of xstest.xs. Do not edit this file, edit xstest.xs instea +d. * * ANY CHANGES MADE HERE WILL BE LOST! * */ #line 1 "xstest.xs" #include "EXTERN.h" #include "perl.h" #include "XSUB.h" #line 16 "xstest.c" XS(XS_xstest_hello) { dXSARGS; if (items != 0) Perl_croak(aTHX_ "Usage: xstest::hello()"); { #line 11 "xstest.xs" printf("Hello, world!\n"); #line 25 "xstest.c" } XSRETURN_EMPTY; } #ifdef __cplusplus extern "C" #endif XS(boot_xstest) { dXSARGS; char* file = __FILE__; XS_VERSION_BOOTCHECK ; newXS("xstest::hello", XS_xstest_hello, file); XSRETURN_YES; }
