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

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 firstly.

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 xorriso

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

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 layout).

2.2 Download third-part source code and tool

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 a 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:

1. Only grub2/EDK2/IPXE will be recompiled in all_in_one.sh. Other part contains the binaries and are few modified, so will no be recompiled everytime.

You can rebuild these parts separately if you want.

2. 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 ==

cd /home/Ventoy-master/EDK2

After that, copy EXFAT/shared/mkexfatfs ===> /home/Ventoy-master/INSTALL/tool/mkexfatfs_64

After that, copy EXFAT/shared/mount.exfat-fuse ===> /home/Ventoy-master/INSTALL/tool/mount.exfat-fuse_64

Use the same build step to build exfat-util 32bit in a 32bit CentOS system and get mkexfatfs_32 and mount.exfat-fuse_32

4.10 == Build vtoy_fuse_iso_64/vtoy_fuse_iso_32 ==

cd /home/Ventoy-master/FUSEISO
