Subject: [PATCH] Don't attempt to export the start and _start symbols for
|
|
grub-emu
|
|
|
|
Commit 318ee04aadc ("make better backtraces") reworked the backtrace logic
|
|
but the changes lead to the following build error on the grub-emu platform:
|
|
|
|
grub_emu_lite-symlist.o:(.data+0xf08): undefined reference to `start'
|
|
collect2: error: ld returned 1 exit status
|
|
make[3]: *** [Makefile:25959: grub-emu-lite] Error 1
|
|
make[3]: *** Waiting for unfinished jobs....
|
|
cat kernel_syms.input | grep -v '^#' | sed -n \
|
|
-e '/EXPORT_FUNC *([a-zA-Z0-9_]*)/{s/.*EXPORT_FUNC *(\([a-zA-Z0-9_]*\)).*/defined kernel '""'\1/;p;}' \
|
|
-e '/EXPORT_VAR *([a-zA-Z0-9_]*)/{s/.*EXPORT_VAR *(\([a-zA-Z0-9_]*\)).*/defined kernel '""'\1/;p;}' \
|
|
| sort -u >kernel_syms.lst
|
|
|
|
The problem is that start and _start symbols are exported unconditionally,
|
|
but these aren't defined for grub-emu since is an emultaed platform so it
|
|
doesn't have a startup logic. Don't attempt to export those for grub-emu.
