The following list describes steps to make PCC the system compiler.
__Microsoft Windows__
You must install the w32api and mingw-runtime libraries available from the [pcc ftp server](http://pcc.ludd.ltu.se/ftp/pub/win32/). These libraries expand into the /usr/local/i386-pe/ directory. You can copy these files to your windows machine and follow the directions [here](http://pcc.ludd.ltu.se/building/) for compiling on the Microsoft Windows platform.
You must also build and install the pcc-libs module which contains libpcc.a.
__Debian GNU/Linux 4.0r0__
You must build and install the pcc-libs module which contains libpcc.a and stddef.h header files.
__SuSE Linux Ent Svr 10__
You must build and install the pcc-libs module which contains libpcc.a and stddef.h header files.
__Mandriva Corporate Server 4.0__
You must build and install the pcc-libs module which contains libpcc.a and stddef.h header files.
__Red Hat Ent Linux 5__
You must build and install the pcc-libs module which contains libpcc.a and stddef.h header files.
__Ubuntu Linux 8.04__
You must build and install the pcc-libs module which contains libpcc.a and stddef.h header files.
The alloca.h glibc header file is broken so alloca() doesn't work. The header file undefines alloca and then fails to set it to something useful if _GNUC_ is not defined.
Try putting the followign into /usr/local/include/pcc/alloca.h:
#ifndef _ALLOCA_H
#define _ALLOCA_H
#include <features.h>
#define __need_size_t
#include <stddef.h>
__BEGIN_DECLS
/* Remove any previous definitions. */
#undef alloca
/* Allocate a block that will be freed when the calling function exits. */
extern void *alloca (size_t __size) __THROW;
#if defined(__GNUC__) || defined(__PCC__)
# define alloca(size) __builtin_alloca (size)
#endif /* GCC. */
__END_DECLS
#endif /* alloca.h */
__Ubuntu Linux: Intrepid Ibex 8.10__
You must build and install the pcc-libs module which contains libpcc.a and stddef.h header files.
me@MY-BOX:~$ cvs -d :pserver:anonymous@pcc.ludd.ltu.se:/cvsroot co pcc-libs
me@MY-BOX:~$ cd pcc-libs
me@MY-BOX:~/pcc-libs$ ./configure
me@MY-BOX:~/pcc-libs$ make
me@MY-BOX:~/pcc-libs$ sudo make install
Then build and install pcc
me@MY-BOX:~$ cvs -d :pserver:anonymous@pcc.ludd.ltu.se:/cvsroot co pcc
me@MY-BOX:~$ cd pcc
me@MY-BOX:~/pcc$ ./configure
me@MY-BOX:~/pcc$ gedit cc/cpp/Makefile cc/ccom/Makefile&
delete the "-Werror" from the "CFLAGS =" line in both files and save
me@MY-BOX:~/pcc$ make
me@MY-BOX:~/pcc$ sudo make install
__MidnightBSD-current (i386/sparc64)__
Unless you're using the MirPorts Framework to install pcc, you must build and install the pcc-libs module.
__MirBSD-current (i386)__
The MirPorts Framework contains a tested snapshot in lang/pcc, which works without the pcc-libs module, as the required quad functions are all part of libc.
Building pcc from source (including bootstrapping) is possible as well.
The necessary header changes are integrated starting MirBSD #10. It is, however, not possible yet to compile MirBSD itself with pcc; using it as ports compiler is planned.
__NetBSD-current (i386/mips/arm/powerpc)__
NetBSD-current (to be released as NetBSD 5.0) should contain support for PCC to build applications.
Currently it is not possible to build the complete NetBSD operating system with build.sh using PCC.
__NetBSD 4.0 (i386/mips/arm/powerpc)__
NetBSD 4.0 needs at least this change:

__Mac OS X 10.4 (powerpc)__
You must build and install the pcc-libs module which contains libpcc.a
Additionally, stdargs.h only works with gcc. Paste the following lines into /usr/local/lib/pcc/stdarg.h:
#ifndef _STDARG_H_
#define _STDARG_H_
#define va_list char *
#define _VA_LIST
#define va_start(ap, last) __builtin_stdarg_start((ap), last)
