==========================================

1. Compile Enviroment

==========================================

My build envrioment is CentOS 7.8 x86_64. So here I first explain how to create the build environment from scratch.

Because Ventoy is based on many open source projects, so the environment is important. I suggest you test it on a virtual machine first.

1.1 Install CentOS 7.8

I use CentOS-7-x86_64-Everything-2003.iso and select Minimal install

1.2 Install Packages

yum install \

libXpm net-tools bzip2 wget vim gcc gcc-c++ samba dos2unix glibc-devel glibc.i686 glibc-devel.i686 \

mpfr.i686 mpfr-devel.i686 zlib.i686 rsync autogen autoconf automake libtool gettext* bison binutils \

flex device-mapper-devel SDL libpciaccess libusb freetype freetype-devel gnu-free-* qemu-* virt-* \

libvirt* vte* NetworkManager-bluetooth brlapi fuse-devel dejavu* gnu-efi* pesign shim \

iscsi-initiator-utils grub2-tools zip nasm acpica-tools glibc-static zlib-static

==========================================

2. Download Source Code

==========================================

2.1 Download Ventoy source code from github and decompress it.

Next I assume that you have unzipped the code into the /home directory (check /home/Ventoy-master/README.md file for the directory level).

2.2 Download third-part source code

2.3 Prepare third-part tools

cd /home/Ventoy-master/DOC/

tar xf musl-1.2.1.tar.gz

cd musl-1.2.1

./configure && make install

tar xf /opt/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu.tar.xz -C /opt

tar xf /opt/aarch64--uclibc--stable-2020.08-1.tar.bz2 -C /opt

2.4 Set PATH envrioment

export PATH=$PATH:/opt/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/bin:/opt/aarch64--uclibc--stable-2020.08-1/bin

better to add this line to /root/.bashrc and relogin as root

==========================================

3. All in one script

==========================================

I have made the whole build process in all_in_one.sh, you can run this script to build and pack ventoy.

If you want to compile a certain part separately, you can continue to refer to the later chapters of this text.

cd /home/Ventoy-master/INSTALL

sh all_in_one.sh

It should be noted that, some part of Ventoy has 32bit&64bit version (like 4.9 4.10 4.11 follows)

all_in_one.sh only build 64bit version of them, if you want to rebuild the 32bit verison. You should create a 32bit CentOS environment and build them.

Fortunately these parts are few modified, you only need to build once or you can directly use the binary I have built.

Besides, after a fully compile and pack, you can only build the part you modified (for example grub2) and run ventoy_pack.sh to generate the package.

==========================================

4. Build every part of Ventoy

==========================================

4.1 == Build grub2 ==

cd /home/Ventoy-master/GRUB2

sh buildgrub.sh

4.2 == Build ipxe.krn ==

cd /home/Ventoy-master/IPXE

sh buildipxe.sh

4.3 == Build Ventoy2Disk.exe ==

Ventoy2Disk.exe is the installer in Windows platform. And it must be built in Windows with Microsoft Visual Studio (2013+).

Open /home/Ventoy-master/Ventoy2Disk/Ventoy2Disk.sln with Visual Studio and build it.

4.4 == Build vtoyjump64.exe/vtoyjump32.exe ==

vtoyjump64.exe/vtoyjump32.exe is used to mount iso file in windows PE. You should install Microsoft Visual Studio (2013+) to build it.

Open /home/Ventoy-master/vtoyjump/vtoyjump.sln with Visual Studio and build it (64&32).

4.5 == Build dmsetup ==

Please refer to DMSETUP/build.txt

4.6 == Build ventoy_x64.efi ==
