 # thirdparty-windows-amd64 (tcc64, tccwin64)
 
 This repository contains a prebuilt [tcc compiler](https://repo.or.cz/tinycc.git),
-imported from https://github.com/vlang/tccbin_win, 
-whose source code is cut at commit 
-[9eef339](https://repo.or.cz/tinycc.git/commit/9eef33993ade2d3b964d19b1081978ceae5d359d) (20200605),
-from the mob branch. 
+from the mob branch.
 
 It is a ***minimalistic*** C compiler, that is just enough to be V's
 backend. It is small and fast, although it does not produce optimised
 executables. For that, use MSVC, GCC or CLANG instead.
 
 ## Target OS
-The tcc build here produces ***64-bit executables***, compatiable with ***64-bit Windows***.  
+The tcc build here produces ***64-bit executables***, compatiable with ***64-bit Windows***.
+
+## Build from source
+1. Make sure you have `MSVC` and `git` installed.
+2. Run the `build.bat` from ***current directory***, 
+   ```sh
+	.\scripts\build.bat
+   ```
+3. If you want to build tcc with a special commit, run the `build.bat` with COMMIT=..., 
+   ```sh
+   .\scripts\build.bat COMMIT=68000c01ae5b90a4b9677f7725a286e9057e9767
+   ```
+
+## Note
+1. tcc is enabled with `BACKTRACE` and `BCHECK` via patch `win32\build-tcc.bat` (see `scripts\build-tcc.bat.patch`);
+2. `include\tcc` is removed, as we use a pre-compiled `lib\openlibm.o` (see https://github.com/JuliaMath/openlibm)
+
 
 ## What if V reports missing C header files?
 In this case, please create a PR to help us improve it.
 Please try finding the missing header files in
 [this](http://download.savannah.gnu.org/releases/tinycc/winapi-full-for-0.9.27.zip)
-official full version of the WINAPI headers for tcc, 
+official full version of the WINAPI headers for tcc,
 or in the releases of [MinGW64](https://sourceforge.net/projects/mingw-w64/).
 
 Most of the time, the ported headers should just work if you copy them inside the include/ folder,
