I recently built a gcc cross compiler for the sun3 port on a Sparc 20 running
Solaris 2.6. I have compiled several simple test programs with some success. I
created a modified xmkmf and call imake with appropriate options and then I
tried to compile the xfig drawing tool (from original source, not the NetBSD
packages source). I got the following errors.

make -R d_arcbox.o
cc -O     -I/usr/local/m68k-sun3-netbsd1.3.2/lib/X11/config
-I/usr/local/m68k-sun3-netbsd1.3.2/lib/X11/config/exports/include  -DNOSTDHDRS

The definitions to which the "conflicting types" errors refer are as follows:

usr/local/m68k-sun3-netbsd1.3.2/include/errno.h:59:

#if !defined(_ANSI_SOURCE) && !defined(_POSIX_SOURCE) && !defined(_XOPEN_SOURCE)
extern __const int sys_nerr;
extern __const char *__const sys_errlist[];
#endif

and

/usr/local/m68k-sun3-netbsd1.3.2/include/X11/Xos.h:121:

#if (defined(X_NOT_STDC_ENV) || (defined(sun) && !defined(SVR4)) || defined(macI
I)) && !defined
(__GLIBC__)
#ifndef strerror
extern char *sys_errlist[];
extern int sys_nerr;
#define strerror(n) \
    (((n) >= 0 && (n) < sys_nerr) ? sys_errlist[n] : "unknown error")
#endif
#endif

These do contain different definitions but it may be that my defines are not set
correctly. I am going to run a test piece of code on my NetBSD system to
discover the settings for these defines and compare with the cross compiler.

But whilst I am waiting to try this out can anyone answer the following
question.
Is it absolutely necessary to get the NetBSD distributions for any package I
want to compile or will vanilla distributions do in most cases.


Thanks for any replies.
