|
85 \section1 GCC |
|
86 |
|
87 \section2 GCC on Windows (MinGW) |
|
88 |
|
89 We have tested Qt with this compiler on Windows XP. |
|
90 The minimal version of MinGW supported is: |
|
91 |
|
92 \list |
|
93 \o GCC 3.4.2 |
|
94 \o MinGW runtime 3.7 |
|
95 \o win32api 3.2 |
|
96 \o binutils 2.15.91 |
|
97 \o mingw32-make 3.80.0-3 |
|
98 \endlist |
|
99 |
|
100 \section2 GCC 4.0.0 |
|
101 |
|
102 The released package of the compiler has some bugs that lead to miscompilations. |
|
103 We recommend using GCC 4.0.1 or later, or to use a recent CVS snapshot of the |
|
104 GCC 4.0 branch. The version of GCC 4.0.0 that is shipped with Mac OS X 10.4 |
|
105 "Tiger" is known to work with Qt for Mac OS X. |
|
106 |
|
107 \section2 HP-UX |
|
108 |
|
109 The hpux-g++ platform is tested with GCC 3.4.4. |
|
110 |
|
111 \section2 Solaris |
|
112 |
|
113 Please use GCC 3.4.2 or later. |
|
114 |
|
115 \section2 Mac OS X |
|
116 |
|
117 Please use the latest GCC 3.3 from Apple or a later version of GCC 3. |
|
118 The gcc 3.3 that is provided with Xcode 1.5 is known to generate bad code. |
|
119 Use the November 2004 GCC 3.3 updater \l{http://connect.apple.com}{available from Apple}. |
|
120 |
|
121 \section2 GCC 3.4.6 (Debian 3.4.6-5) on AMD64 (x86_64) |
|
122 |
|
123 This compiler is known to miscompile some parts of Qt when doing a |
|
124 release build. There are several workarounds: |
|
125 |
|
126 \list 1 |
|
127 \o Use a debug build instead. |
|
128 \o For each miscompilation encountered, recompile the file, removing the -O2 option. |
|
129 \o Add -fno-gcse to the QMAKE_CXXFLAGS_RELEASE. |
|
130 \endlist |
|
131 |
|
132 \section1 HP ANSI C++ (aCC) |
|
133 |
|
134 The hpux-acc-32 and hpux-acc-64 platforms are tested with aCC A.03.57. The |
|
135 hpuxi-acc-32 and hpuxi-acc-64 platforms are tested with aCC A.06.10. |
|
136 |
|
137 \section1 Intel C++ Compiler |
|
138 |
|
139 Qt supports the Intel C++ compiler on both Windows and Linux. |
|
140 However, there are a few issues on Linux (see the following |
|
141 section). |
|
142 |
|
143 \section2 Intel C++ Compiler for Linux |
|
144 |
|
145 Nokia currently tests the following compilers: |
|
146 |
|
147 \list |
|
148 |
|
149 \o Intel(R) C++ Compiler for applications running on IA-32, |
|
150 Version 10.1 Build 20080602 Package ID: l_cc_p_10.1.017 |
|
151 |
|
152 \o Intel(R) C++ Compiler for applications running on Intel(R) 64, |
|
153 Version 10.1 Build 20080602 Package ID: l_cc_p_10.1.017 |
|
154 |
|
155 \endlist |
|
156 |
|
157 We do not currently test the IA-64 (Itanium) compiler. |
|
158 |
|
159 \section2 Known Issues with Intel C++ Compiler for Linux |
|
160 |
|
161 \list |
|
162 |
|
163 \o Precompiled header support does not work in version 10.0.025 |
|
164 and older. For these compilers, you should configure Qt with |
|
165 -no-pch. Precompiled header support works properly in version |
|
166 10.0.026 and later. |
|
167 \o Version 10.0.026 for Intel 64 is known to miscompile qmake when |
|
168 building in release mode. For now, configure Qt with |
|
169 -debug. Version 10.1.008 and later can compile qmake in release |
|
170 mode. |
|
171 \o Versions 10.1.008 to 10.1.015 for both IA-32 and Intel 64 are |
|
172 known crash with "(0): internal error: 0_47021" when compiling |
|
173 QtXmlPatterns, QtWebKit, and Designer in release mode. Version |
|
174 10.1.017 compiles these modules correctly in release mode. |
|
175 \endlist |
|
176 |
|
177 \section2 Intel C++ Compiler (Windows, Altix) |
|
178 |
|
179 Qt 4 has been tested successfully with: |
|
180 |
|
181 \list |
|
182 \o Windows - Intel(R) C++ Compiler for 32-bit applications, |
|
183 Version 8.1 Build 20050309Z Package ID: W_CC_PC_8.1.026 |
|
184 \o Altix - Intel(R) C++ Itanium(R) Compiler for Itanium(R)-based |
|
185 applications Version 8.1 Build 20050406 Package ID: l_cc_pc_8.1.030 |
|
186 \endlist |
|
187 |
|
188 We currently only test the Intel compiler on 32-bit Windows versions. |
|
189 |
|
190 \section1 MIPSpro (IRIX) |
|
191 |
|
192 \bold{IRIX is an unsupported platform. See the \l{Supported Platforms} page |
|
193 and Qt's Software's online \l{Platform Support Policy} page for details.} |
|
194 |
|
195 Qt 4.4.x requires MIPSpro version 7.4.2m. |
|
196 |
|
197 Note that MIPSpro version 7.4.4m is currently not supported, since it has |
|
198 introduced a number of problems that have not yet been resolved. |
|
199 We recommend using 7.4.2m for Qt development. However, please note the |
|
200 unsupported status of this platform. |
|
201 |
|
202 \target Sun Studio |
|
203 \section1 Forte Developer / Sun Studio (Solaris) |
|
204 |
|
205 \section2 Sun Studio |
|
206 |
|
207 Qt is tested using Sun Studio 12 (Sun CC 5.9). Go to |
|
208 \l{Sun Studio Patches} page on Sun's Web site to download |
|
209 the latest patches for your Sun compiler. |
|
210 |
|
211 Please note that Qt 4.6 is stricter in its STL requirements and |
|
212 that the default STL implementation used by Sun CC does not pass |
|
213 those requirements. This does not affect binary compatibility and |
|
214 you can continue to use STL in your own code, but Qt's |
|
215 STL-compatibility functions will be disabled. |
|
216 |
|
217 Sun CC ships with a secondary STL implementation (called stlport4) |
|
218 which is standards-compliant and can be used by Qt. You can enable |
|
219 it by passing the -library=stlport4 option to the compiler. Note |
|
220 that this does not affect Qt's binary compatibility, but it may |
|
221 affect that of other libraries and programs that use STL. |
|
222 |
|
223 \section2 Sun WorkShop 5.0 |
|
224 |
|
225 Sun WorkShop 5.0 is not supported with Qt 4. |
|
226 |
|
227 \section1 Visual Studio (Windows) |
|
228 |
|
229 We do most of our Windows development on Windows XP, using Microsoft |
|
230 Visual Studio .NET 2005 and Visual Studio 2008 (both the 32- and 64-bit |
|
231 versions). |
|
232 |
|
233 Qt works with the Standard Edition, the Professional Edition and Team |
|
234 System Edition of Visual Studio 2005. |
|
235 |
|
236 We also test Qt 4 on Windows XP with Visual Studio .NET and Visual Studio 2003. |
|
237 |
|
238 In order to use Qt with the Visual Studio 2005/2008 Express Edition you need |
|
239 to download and install the platform SDK. Due to limitations in the |
|
240 Express Edition it is not possible for us to install the Qt Visual |
|
241 Studio Integration. You will need to use our command line tools to |
|
242 build Qt applications with this edition. |
|
243 |
|
244 The Visual C++ Linker doesn't understand filenames with spaces (as in |
|
245 \c{C:\Program files\Qt\}) so you will have to move it to another place, |
|
246 or explicitly set the path yourself; for example: |
|
247 |
|
248 \snippet doc/src/snippets/code/doc_src_compiler-notes.qdoc 0 |
|
249 |
|
250 If you are experiencing strange problems with using special flags that |
|
251 modify the alignment of structure and union members (such as \c{/Zp2}) |
|
252 then you will need to recompile Qt with the flags set for the |
|
253 application as well. |
|
254 |
|
255 If you're using Visual Studio .NET (2002) Standard Edition, you should be |
|
256 using the Qt binary package provided, and not the source package. |
|
257 As the Standard Edition does not optimize compiled code, your compiled |
|
258 version of Qt would perform suboptimally with respect to speed. |
|
259 |
|
260 With Visual Studio 2005 Service Pack 1 a bug was introduced which |
|
261 causes Qt not to compile, this has been fixed with a hotfix available |
|
262 from Microsoft. See this |
|
263 \l{http://qt.nokia.com/developer/faqs/faq.2006-12-18.3281869860}{Knowledge Base entry} |
|
264 for more information. |
|
265 |
|
266 \section1 IBM xlC (AIX) |
|
267 |
|
268 The makeC++SharedLib utility must be in your PATH and be up to date to |
|
269 build shared libraries. From IBM's |
|
270 \l{http://www.redbooks.ibm.com/abstracts/sg245674.html}{C and C++ Application Development on AIX} |
|
271 Redbook: |
|
272 |
|
273 \list |
|
274 \o "The second step is to use the makeC++SharedLib command to create the |
|
275 shared object. The command has many optional arguments, but in its |
|
276 simplest form, can be used as follows:" |
|
277 \snippet doc/src/snippets/code/doc_src_compiler-notes.qdoc 1 |
|
278 \o "The full path name to the command is not required; however, to avoid |
|
279 this, you will have to add the directory in which it is located to |
|
280 your PATH environment variable. The command is located in the |
|
281 /usr/vacpp/bin directory with the VisualAge C++ Professional for AIX, |
|
282 Version 5 compiler." |
