解决方法

方法1

buildroot/output/alientek_rv1126/build/libgpg-error-1.27/libgpg-error-1.33/lang/cl/mkerrcodes.awk
buildroot/output/alientek_rv1126/build/libgpg-error-1.27/libgpg-error-1.33/src/mkerrcodes.awk
buildroot/output/alientek_rv1126/build/libgpg-error-1.27/libgpg-error-1.33/src/mkerrcodes1.awk
buildroot/output/alientek_rv1126/build/libgpg-error-1.27/libgpg-error-1.33/src/mkerrcodes2.awk
buildroot/output/alientek_rv1126/build/libgpg-error-1.27/libgpg-error-1.33/src/mkerrnos.awk
buildroot/output/alientek_rv1126/build/libgpg-error-1.27/libgpg-error-1.33/src/mkstrtable.awk

将这些文件中的

!header {
  sub (/\#.+/, "");

替换为

!header {
sub (/#.+/, "");

方法2

1. 直接替换buildroot/package/libgpg-error/libgpg-error.mk中的版本号为1.37
2. 修改buildroot/package/libgpg-error/libgpg-error.hash文件为

   # Locally calculated after checking pgp signature
   sha256 a519c44fb29b900ee88b06945318fb6a3b93f74d93293b657693e261394e6b82 libgpg-error-1.37.tar.gz
   

3. 清理缓存并重新编译
