==========================================
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 envrioment 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
https://www.fefe.de/dietlibc/dietlibc-0.34.tar.xz ===> /home/Ventoy-master/DOC/dietlibc-0.34.tar.xz
https://ftp.gnu.org/gnu/grub/grub-2.04.tar.xz ===> /home/Ventoy-master/GRUB2/grub-2.04.tar.xz
https://codeload.github.com/tianocore/edk2/zip/edk2-stable201911 ===> /home/Ventoy-master/EDK2/edk2-edk2-stable201911.zip
https://codeload.github.com/relan/exfat/zip/v1.3.0 ===> /home/Ventoy-master/ExFAT/exfat-1.3.0.zip
https://codeload.github.com/libfuse/libfuse/zip/fuse-2.9.9 ===> /home/Ventoy-master/ExFAT/libfuse-fuse-2.9.9.zip
==========================================
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 ==
cd /home/Ventoy-master/EDK2
sh buildedk.sh
4.7 == Build VtoyTool ==
cd /home/Ventoy-master/VtoyTool
sh build.sh
4.8 == Build vtoyfat ==
cd /home/Ventoy-master/vtoyfat/fat_io_lib
sh buildlib.sh
cd /home/Ventoy-master/vtoyfat
sh build.sh
4.9 == Build exfat-util ==
cd /home/Ventoy-master/ExFAT
sh buidlibfuse.sh
sh buidexfat.sh
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
sh build_libfuse.sh
sh build.sh
Use the same build step to build in a 32bit CentOS system and get vtoy_fuse_iso_32
4.11 == Build unsquashfs_64/unsquashfs_32 ==
cd /home/Ventoy-master/SQUASHFS/SRC
sh build_lz4.sh
sh build_lzma.sh
sh build_lzo.sh
sh build_zstd.sh
cd /home/Ventoy-master/SQUASHFS/squashfs-tools-4.4/squashfs-tools
sh build.sh
Use the same build step to build in a 32bit CentOS system and get unsquashfs_32
4.12 == Build vblade_64/vblade_32 ==
cd /home/Ventoy-master/VBLADE/vblade-master
sh build.sh
4.13 == Build zstdcat ==
Please refer to ZSTD/build.txt
4.14 == Build vtoy_gen_uuid ==
cd /home/Ventoy-master/GenUUID
sh build.sh
4.15 == Build xzminidec ==
cd /home/Ventoy-master/xz-embedded-20130513/userspace
make -f ventoy_makefile
strip --strip-all xzminidec
4.16 == Build iso9660_x64.efi ==
This efi driver is from https://github.com/pbatard/efifs
Follow all the build instructions in this project. I modified 3 files (the original and modified source are at /home/Ventoy-master/EDK2/efiffs)
==========================================
5. Binaries

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

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

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:/opt/mips64el-linux-musl-gcc730/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
