During its configure step, libgpg-error needs awk:
configure -> src/gen-lock-obj.sh -> objdump + awk on test binary
This call is used on the output from objdump on a test binary to
retrieve the size of some data structure, and generate accordingly an
internal header (lock-obj-pub.native.h). However, libgpg-error buildroot
package does not depend explicitely on host-gawk: if host-gawk is not
part of the build, or if it is built later than libgpg-error,
libgpg-error autotool tooling will eventually pick the build machine
awk. On top of this issue, despite the configure.ac suggesting that it
supports different implementations of awk, libgpg-error configure step
will not parse correctly the output from objdump when using mawk,
leading to a wrong lock-obj-pub.native.h header being generated:
With gawk:
typedef struct
{
long _vers;
union {
volatile char _priv[24];
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}}}
With mawk:
typedef struct
{
long _vers;
union {
volatile char _priv[0];
long _x_align;
long *_xp_align;
} u;
} gpgrt_lock_t;
#define GPGRT_LOCK_INITIALIZER {1,{{}}}
This issue has been observed for example on Debian 13 with mawk
installed: it fails to parse mtx_size, leading to a size 0, and so
generating crashes at runtime because of the invalid size embedded in
libgpg-error.
Side note: the lock-obj-pub.native.h header file is correctly
generated, when using mawk 1.3.4 20200120 from Debian 12.
The described issue happen with mawk 1.3.4 20250131 from Debian 13.
libgpg-error should be fixed upstream to properly handle this data
structure size guessing even when using mawk, but anyway the
corresponding buildroot package should not randomly use the build
machine host tooling or buildroot-provided host tooling depending on
whether host-gawk has been selected and built before it.
Enforce an explicit dependency on host-gawk for libgpg-error to make
sure that it systematically uses the buildroot-provided awk.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
