 ### Building osslsigncode source with MSYS2 MinGW 64-bit and MSYS2 packages:
 
 1) Download and install MSYS2 from https://msys2.github.io/ and follow installation instructions.
-   Once up and running install even mingw-w64-x86_64-gcc, mingw-w64-x86_64-curl, mingw-w64-x86_64-libgsf.
+   Once up and running install even mingw-w64-x86_64-gcc, mingw-w64-x86_64-curl.
 ```
-  pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-curl mingw-w64-x86_64-libgsf
+  pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-curl
 ```
    mingw-w64-x86_64-openssl and mingw-w64-x86_64-zlib packages are installed with dependencies.
 
 2) Run "MSYS2 MinGW 64-bit" and build 64-bit Windows executables.
 ```
   cd osslsigncode-folder
-  x86_64-w64-mingw32-gcc osslsigncode.c msi.c -o osslsigncode.exe \
-    -lcrypto -lssl -lcurl -lgsf-1 -lgobject-2.0 -lglib-2.0 -lxml2 \

-    -I 'C:/msys64/mingw64/include/glib-2.0' \

     -D 'PACKAGE_BUGREPORT="Michal.Trojnara@stunnel.org"' \
-    -D ENABLE_CURL \
-    -D WITH_GSF
+    -D ENABLE_CURL
 ```
 
 3) Run "Command prompt" and include "c:\msys64\mingw64\bin" folder as part of the path.
 ```
   path=%path%;c:\msys64\mingw64\bin
   cd osslsigncode-folder
