Glossword WAMP source code (NSIS)

Dmitry-Sh (Dmitry Shilnikov) — Wed, 13 Jun 2007 09:12:40 GMT

// NSIS (http://nsis.sourceforge.net/)
// Glossword WAMP (http://sourceforge.net/projects/glossword/)
// Apache, MySQL and PHP are stored in archive usr.exe, directory /usr/local
// phpMyAdmin is in archive htdocs.exe, directory /htdocs/phpmyadmin
// Additionaly you need files with phrases: English.nsh and Russian.nsh
// ------------------------------------------
// English.nsh:
// LangString SECT_01 ${LANG_ENGLISH} "Glossword ${PRODUCT_VERSION}"
// LangString TXT_02 ${LANG_ENGLISH} "Thank you for installing Glossword.\r\nFor news and updates go to http://sourceforge.net/projects/glossword/"
// LangString DESC_SecGw ${LANG_ENGLISH} "Glossword program core files."
// ------------------------------------------
// install.bat
// @echo on
// cls
// SET ipath=%1
// cd "%ipath%/usr/local/apache2/bin"
// httpd.exe -k install -n Apache2_GW
// httpd.exe -k start -n Apache2_GW
// cd "%ipath%/usr/local/mysql5/bin"
