-==========================================
-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

-
-
-
-==========================================
-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

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

+==========================================
+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
+

+    cd /home/Ventoy-master/DOC/

+    cd musl-1.2.1
+    ./configure && make install

+    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.
+
+
+
+==========================================

longpanda	8bbd5a14a3	最近收到一些特殊的错误报告，最后证明是非标准的Ventoy环境的原因。尤其是单分区下环境下使用 Ventoy 。虽然 Ventoy 显示了 Unofficial 的标注信息，但是用户并不会关心，仍然会认为是 Ventoy 的问题。 Ventoy 从一开始就是一个整体的设计，并没有考虑过集成在其他bootloader或分区环境中。 Ventoy 的验证和后续新功能开发也都不会考虑这种非标准的使用方式。因此，我决定禁止 Ventoy 在非标准环境下的使用，并且不再接受放开检查的请求。当然，这个只是Ventoy的默认行为。Ventoy仍然是100%开源的，如果你希望把Ventoy应用在自己的环境中，你可以fork一个分支，然后修改源代码实现。	2020-11-13 16:39:15 +08:00
