Building syslinux against gnu-efi 3.0.10 currently fails with:
|
|
syslinux/efi/main.c:33:8: error: unknown type name ‘jmp_buf’
|
33 | static jmp_buf load_error_buf;
|
| ^~~~~~~
|

|
189 | longjmp(&load_error_buf, 1);

|
| ^~~~~~
|
make[3]: *** [syslinux/mk/efi.mk:63: main.o] Error 1
|
|
This is due to gnu-efi commit 486ba3c3bdd147b7d98159b9e650be60bce0f027
|
("Do not include efisetjmp.h on efi.h"), in which they state:
|
|
Do not include efisetjmp.h on efi.h
|
|
People than really want to use efisetjmp implementation can include
|
the header on their own.

|
So we act as specified, and include <efisetjmp.h> from efi/main.c.
