Building/Compiling my QtWeb...

過年期間心血來潮，想說來研究一下瀏覽器，下載了 Chromium 跟 QtWeb 兩包原始碼，看了看大小，決定還是從小的開始，就 QtWeb 吧。

解開 QtWeb 的原始碼，有給 VS 的專案檔，很好。再看了一下依存性，發現還要加上 Qt 跟 OpenSSL 才能動工。尤其 Build Qt 實在是相當花時間的一件事，檔案也不小，看來當初應該直接挑戰 Chromium 的，不應該看到 2 GB 的壓縮檔就退卻了。

不過還是紀錄一下 Build QtWeb 的過程吧。

1. Download source code package, QtWeb.

• http://code.google.com/p/qtweb/downloads/list

2. Download the dependency packages, including Qt & OpenSSL.

• Qt Libraries 4.8.4 for Windows (VS 2008, 233 MB) 
• Win32 OpenSSL v1.0.1d

3. Install OpenSSL.

4. Install Qt and then build Qt first. // Update: No need to re-build it since the package contains the built binaries.

• Launch "Qt 4.8.4 Command Prompt", could be found in Start Menu, after installing Qt Libraries.
• Type 'configure -openssl -openssl-linked -I \include -L \lib\VC\static OPENSSL_LIBS="-lUser32 -lAdvapi32 -lGdi32 -lCrypt32" OPENSSL_LIBS_DEBUG="-lssleay32MDd -llibeay32MDd" OPENSSL_LIBS_RELEASE="-lssleay32MD -llibeay32MD" ' and press Enter.
• Type 'nmake' and press Enter.

5. Change the language setting for Non-Unicode programs. (My system is Traditional Chinese)

• Control panel / Region and Language / Administrative / Language for Non-Unicode programs > English (US)
• Refer to this: http://blog.csdn.net/skyxfire/article/details/7369387
• Remember to reset the language setting after building program if necessary.

6-a. Build QtWeb via command-line

• Launch "Qt 4.8.4 Command Prompt" and cd to the QtWeb source folder, ex. cd D:\QtWb_src_3.7.5-101\QtWeb.
• Type build.cmd and press Enter.

6-b. Build QtWeb via VS GUI

• Launch VS 2008 via running "Visual Studio with Qt 4.8.4".
• Open QtWeb project in VS 2008.
• Build the project.

對了，Qt 編譯過後，Qt components 都是 Qtxxx4.lib/dll 的名稱，所以 QtWeb 在編譯時，順手改一下 Project settings，以免 link 時找不到檔案。研究一下 QtWeb 先，再來試試 Chromium。若是在 Compile Qt 有問題，也可以參考一下底下這篇。
