gnupg2 uses the libgpg-error library. The libgpg-error library has a
long plan to be renamed to "gpgrt" (see [1]). For the transition, it
provides two configuration scripts "gpg-error-config" (the old,
original one, kept for compatibility) and "gpgrt-config" (which is
meant to be the replacement). When both are detected, "gpgrt-config"
should be preferred.
gnupg2 configure script searches for "gpg-error-config" in the path
provided to --with-libgpg-error-prefix=PFX (more specifically, in
"PFX/bin").
The logic to find "gpgrt-config" is different: it is searched in
paths "$prefix/bin:$PATH". See [2]. On Buildroot, autotools target
packages are configured with "--prefix=/usr", which makes the
configure script to search in the host "/usr/bin".
In some host environment providing such a "/usr/bin/gpgrt-config"
script of an older version, host compilation flags are incorrectly
added for the target, which leads to compilation failures.
The issue can be reproduced in a Buildroot Docker image from [3] in
which the libgpg-error-dev package is added. When tested, the
libgpg-error-dev package was at version 1.38.
In that configuration, gnupg2 configure will output the message:
checking for gpgrt-config... /usr/bin/gpgrt-config
and the compilation fails with a message:
aarch64-buildroot-linux-gnu-gcc: ERROR: unsafe header/library path used in cross-compilation: '-I/usr/include'
Note: it was observed that in some other configurations in which the
host /usr/bin/gpgrt-config was from libgpg-error version 1.46, the
host script was redirecting correctly in the buildroot sysroot.
Since gnupg2 searches for "gpgrt-config" with a
"AC_PATH_PROG(GPGRT_CONFIG, ...)" macro, this patch fixes this
issue by simply forcing the script path in the GPGRT_CONFIG
environment variable.
See also [4] which discussed the "gpgrt-config" search logic.
