Bug#891663: [PATCH] libgpg-error: Add support for the riscv64 architecture
Source: libgpg-error
Version: 1.27-6

Hello,
we are in the process of bootstrapping a Debian port for the
riscv64 architecture (https://wiki.debian.org/RISC-V). The
libgpg-error package is part of the build-dependency chain for
the essential package set, so we need to build it for riscv64 to
be able to complete the bootstrap process.
AIUI, libgpg-error requires a per-architecture header file
"src/syscfg/lock-obj-pub.<arch-triple>.h", which upstream doesn't
provide for riscv64. Based on the information in the header
files for the other architectures, I have created such a file for
riscv64 by cross-building and executing (in qemu) the
gen-posix-lock-obj helper program:
$ riscv64-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I../../src -I.. -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/usr/src/repositories/libgpg-error=. -specs=/usr/share/dpkg/pie-compile.specs -fstack-protector-strong -Wformat -Werror=format-security -Wall -Wpointer-arith -Wno-psabi -fvisibility=hidden -c -o gen-posix-lock-obj.o ../../src/gen-posix-lock-obj.c
$ /bin/bash ../libtool --tag=CC --mode=link riscv64-linux-gnu-gcc -g -O2 -fdebug-prefix-map=/usr/src/repositories/libgpg-error=. -specs=/usr/share/dpkg/pie-compile.specs -fstack-protector-strong -Wformat -Werror=format-security -Wall -Wpointer-arith -Wno-psabi -fvisibility=hidden -specs=/usr/share/dpkg/pie-link.specs -Wl,-z,relro -Wl,-z,now -o gen-posix-lock-obj gen-posix-lock-obj.o
libtool: link: riscv64-linux-gnu-gcc -g -O2 -fdebug-prefix-map=/usr/src/repositories/libgpg-error=. -specs=/usr/share/dpkg/pie-compile.specs -fstack-protector-strong -Wformat -Werror=format-security -Wall -Wpointer-arith -Wno-psabi -fvisibility=hidden -specs=/usr/share/dpkg/pie-link.specs -Wl,-z -Wl,relro -Wl,-z -Wl,now -o gen-posix-lock-obj gen-posix-lock-obj.o
$ ./gen-posix-lock-obj # (executed in qemu via binfmt-misc)
## lock-obj-pub.riscv64-unknown-linux-gnu.h
## File created by gen-posix-lock-obj - DO NOT EDIT
## To be included by mkheader into gpg-error.h
typedef struct
{
long _vers;
union {
volatile char _priv[40];
long _x_align;
long *_xp_align;
} u;
} gpgrt_lock_t;
#define GPGRT_LOCK_INITIALIZER {1,{{0,0,0,0,0,0,0,0, \
0,0,0,0,0,0,0,0, \
0,0,0,0,0,0,0,0, \

0,0,0,0,0,0,0,0}}}

Attached is the raw header file as well as a patch for the
packaging to carry this header file as a Debian patch. I would
apprechiate very much if you could upload a new package version
that includes this patch to unstable in the near future as we
depend on it for continuing our bootstrap efforts.
Regards,
Karsten
