From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) Description of problem: Compiling kdevelop source by Intel C/C++ compiler I've received such error message: c++ -DHAVE_CONFIG_H -I. -I. -I../.. -I/usr/include/kde -I/usr/lib/qt3- gcc2.96/include -I/usr/X11R6/include -DQT_THREAD_SUPPORT -D_REENTRANT -Wnon- virtual-dtor -Wno-long-long -Wbad-function-cast -Wundef -Wall -pedantic -W - Wpointer-arith -Wmissing-prototypes -Wwrite-strings -ansi -D_XOPEN_SOURCE=500 - D_BSD_SOURCE -Wcast-align -Wconversion -fno-builtin -g -O2 -O2 -march=i386 - mcpu=i686 -DNDEBUG -DNO_DEBUG -D_GNU_SOURCE -fno-exceptions -fno-check-new - ftemplate-depth-99 -Wp,-MD,.deps/kwview.pp -c kwview.cpp -fPIC -DPIC kwdialog.h(29): error: identifier "QComboBox" is undefined QComboBox *search; ^ kwdialog.h(30): error: identifier "QComboBox" is undefined QComboBox *replace; ^ compilation aborted for kwview.cpp (code 2) Problem here is that "-ansi -pedantic" comand-line options cause strict ANSI C++ checking. According to ANSI C++, code in kwdialog.h is illegal, because class QComboBox isn't declared evidently in included Qt headers (you forgot <qcombobox.h>) and declared only in class QListBoxItem (qlistbox.h) as friend class - you can ensure in it looking preprocessed file. This is enough for C++ without ANSI check but no enough for strict ANSI dialect. Look at section 11.4 paragraph 2 of the C++ standart: "A class shall not be defined in a friend declaration.", also paragraph 7: "A name nominated by a friend declaration shall be accessible in the scope of the class containing the friend declaration." GNU C/C++ compiler doesn't do really STRICT ANSI check so illegal code passes thru it successfully. But to increase Red Hat Linux portability you should correct code in <kwdialog.h> conforming ANSI C++ standart. Workaround here is add #include <qcombobox.h> to list of kwdialog.h includes. I'll attach the patch with this modification - please look at it. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. I'm afraid you won't be able to reproduce the error because you don't have compiler I used and this error doesn't appear with current GNU C/C++ compiler. Actual Results: Compilation error. Expected Results: Biult package. Additional info:
Created attachment 84784 [details] Patch doing <kwdialog.h> ANSI C++ compatible (#include added)
it's fixed in 2.1.5-1. thanks for your patch file.
