fix gcc 7,8,9 errors

[memoarfaa]

The pull request was accidentally done in visual studio code, while I'm still working on some issues in the private repository in my local build development environment, but since it's done let's discuss this

gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0 GNU objcopy (GNU Binutils for Ubuntu) 2.34 ./build ERROR: checking whether objcopy works for absolute addresses... configure: error: gcc cannot link at address 2000

[memoarfaa]

yes

@a1ive I don't understand what do you mean First do you mean you tried and failed? How is that version that I work on most of the time is the same version !!! Secondly, I do not use build script I use ./autogen.sh to update make files also

I stopped development with gcc,make,grub and grub4dos from some time ago because i was busy with my job in .net core and .net framework but now I'm here so now I working in modern development environment parallel to it https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiO5u6zzoT5AhWYhM4BHbC3BHQQFnoECBUQAQ&url=https%3A%2F%2Fcode.visualstudio.com%2F&usg=AOvVaw15O90sm1ios8AUpw56hCml in windows 10 with https://docs.microsoft.com/en-us/windows/wsl/install

you can name it The Old New Thing https://devblogs.microsoft.com/oldnewthing/author/oldnewthing I will upload mp4 record here beside this conversation until that I uploaded the patches here you can try it tested with "gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04) GNU objcopy (GNU objcopy (GNU Binutils for Ubuntu) 2.30)" "gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0 GNU objcopy (GNU Binutils for Ubuntu) 2.34" "gcc version 10.2.1 20210110 (Debian 10.2.1-6) GNU objcopy (GNU Binutils for Debian) 2.35.2" still some patches not uploaded yet

objcopy and no-pie.zip

I forget this for 0.4.6a branch only efi branches still need some work

git clone --depth 1 -b build https://github.com/memoarfaa/grub4dos
cd grub4dos
git log
./autogen.sh

I saw

objcopy doesn't accept build-id=none so objcopy required .note.gnu.build-id for debugging can you please edit stage2/Makefile.am

$(AM_V_OBJCOPY) -O binary $< $@

replace with $(AM_V_OBJCOPY) -O binary -R .note -R .comment -R .note.gnu.build-id $< $@

[a1ive]

It doesn't work either.

@a1ive I found the problem occurred only if your operating system is server edition so Ubuntu Desktop no problem but Ubuntu server still has problem I will try to fix it

[memoarfaa]

@a1ive I didn't really know who you were, so please excuse me I made sure it was a test from you So please tell me why the development environment in Windows has a problem http://bbs.c3.wuyou.net/forum.php?mod=redirect&goto=findpost&ptid=427888&pid=4426541&fromuid=501600 And I'll just try to follow some of your instructions if you want to guide me grldr.zip

[memoarfaa]

@a1ive I update my branch 0.4.6a and open other pull request can you try it I tested it in Ubuntu 22.04.1 LTS on Windows 10 x86_64 with gcc 11, gcc 10 and gcc 9

in Ubuntu wsl type

sudo apt-get -y update

sudo apt install -y gcc gcc-multilib nasm upx upx-ucl p7zip-full autoconf automake make patch binutils-dev liblzma-dev syslinux isolinux genisoimage
