@12 I'm not using Solaris, this is on a Steam Deck which runs Linux.

@12 I got further by adding this to my sys/cdefs.h:

#define __IDSTRING(_prefix,_s) /* nothing */
#define __COPYRIGHT(_s) /* nothing */
#define __FBSDID(_s) /* nothing */
#define __RCSID(_s) /* nothing */
#define __SCCSID(_s) /* nothing */

@madewokherd ok so we have /Library/depot/pkgsrc/bootstrap/, is it in there? If so, where? or is it in archivers/libarchive?

@12 Mine was on the host system.

@madewokherd er. That's confusing then

@madewokherd we're running it again to try and get a fuller error so you might be able to see wtf is going on

@madewokherd well that's a warning not an error, so it hasn't hit The Problem yet:

/Library/depot/pkgsrc/bootstrap/work/bmake/var.c: In function 'Var_Export1':
/Library/depot/pkgsrc/bootstrap/work/bmake/var.c:651:6: warning: implicit declar
ation of function 'setenv' [-Wimplicit-function-declaration]

@madewokherd ok, so installing libarchive from CSW is getting it further than it was it's doing, like, stuff? oo, and it's now runing a ./configure for.... something

@madewokherd well that's the most cursed command we've ever seen:

(cd /Library/depot/pkgsrc/bootstrap/work/sed; env INSTALL='/Library/pkg/bin/install-sh -c' CPPFLAGS=' -I../libnbcompat' LDFLAGS=' -L../libnbcompat' LIBS=' -lnbcompat' /usr/bin/bash ./configure -C --prefix=/Library/pkg --infodir=/Library/pkg/info --mandir=/Library/pkg/man --sysconfdir=/Library/pkg/etc --program-transform-name='s,sed,nbsed,' && /Library/depot/pkgsrc/bootstrap/work/bin/bmake -j1

@madewokherd oo! we might have fixed it. Removed the #ifdef in ./archivers/libarchive/files/libarchive/archive_pack_dev.c:40:9

@madewokherd ah. This is on SUN-SPARC-SOLARIS2.9. We feel like adding that would just cause more rrors... We really need an ULTRASparc

@12 I'm pretty sure those macros are only used to embed metadata, so they can be safely defined out.

@madewokherd hhhhh we have no idea where that file is relative to / on our Solaris box, ngl.
