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.

This is a bug in MinGW. You can download a fixed version at http://public.activestate.com/gsar/gcc-2.95.2-msvcrt.zip	[reply]

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.

Actually xstest.c dosen't call strcmp at all. The relevant code is xstest.xs: `#include "EXTERN.h" #include "perl.h" #include "XSUB.h" MODULE = xstest PACKAGE = xstest void hello() CODE: printf("Hello, world!\n");` [download] xstest.c: /* * 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; } [download]	[reply] [d/l] [select]
