| Subject: build: Fix GRUB i386-pc build with Ubuntu gcc |
| |
| With recent versions of gcc on Ubuntu a very large lzma_decompress.img file is |
| output. (e.g. 134479600 bytes instead of 2864.) This causes grub-mkimage to |
| fail with: "error: Decompressor is too big." |
| |
| This seems to be caused by a section .note.gnu.property that is placed at an |
| offset such that objcopy needs to pad the img file with zeros. |
| |
| This issue is present on: |
| Ubuntu 19.10 with gcc (Ubuntu 8.3.0-26ubuntu1~19.10) 8.3.0 |
| Ubuntu 19.10 with gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008 |
| |
| This issue is not present on: |
| Ubuntu 19.10 with gcc (Ubuntu 7.5.0-3ubuntu1~19.10) 7.5.0 |
| RHEL 8.0 with gcc 8.3.1 20190507 (Red Hat 8.3.1-4) |
| |
| The issue can be fixed by removing the section using objcopy as shown in |
| this patch. |
