内容:
刚用QT，遇到了问题，翻了以前的帖子，无果。所以开帖请教
环境:
windows 2k
qt-win-opensource-4.1.0-mingw.exe
MinGW-3.2.0
MSYS-1.0.10
mingw32-make-3.80.0-3
Designer 简单拖了个UI, uic->qmake->make,出错
出错信息如下:
$ make
make -f Makefile.Debug

看样子是路径设置的不正确。
include路径里找不到std::string
#2 [XChinux 01-05 21:47]
如果你用g++编译一个简单的C++程序而也通不过的话，说明就是路径不正确。你试试。

我开始也想到了这个
我试过把sgi stl直接放在d:/sgi_stl下
然后make -I /d/sgi_stl
但问题依旧呀
是不是不能这样加搜索路径
#4 [XChinux 01-06 10:11]
还有include路径，不光是ld路径
#5 [yoke_wolf 01-06 12:00]
先谢谢了
这里说的....具体要怎么设？
我makefile直接改这样都不行:
CC = gcc
CXX = g++
LEX = flex
YACC = byacc
DEFINES = -DUNICODE -DQT_LARGEFILE_SUPPORT -DQT_DLL -DQT_GUI_LIB -DQT_CORE_LIB -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN
CFLAGS = -g -g -Wall $(DEFINES)
CXXFLAGS = -g -g -frtti -fexceptions -Wall $(DEFINES)
LEXFLAGS =
YACCFLAGS = -d
INCPATH = -I"D:/soft/devtools/SDK/QtForMinGW/include/QtCore" -I"D:/soft/devtools/SDK/QtForMinGW/include/QtGui" -I"D:/soft/devtools/SDK/QtForMinGW/include" -I"." -I"D:/soft/devtools/SDK/QtForMinGW/include/ActiveQt" -I"debug" -I"." -I"D:/soft/devtools/SDK/QtForMinGW/mkspecs/win32-g++" -I"D:/SGI_STL"
LINK = g++
LFLAGS = -mthreads -Wl,-enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -Wl,-subsystem,windows
LIBS = -L"d:\SGI_STL" -L"D:\soft\devtools\SDK\QtForMinGW\lib" -lmingw32 -lqtmaind -lQtGuid4 -lQtCored4
QMAKE = qmake
IDC = D:\soft\devtools\SDK\QtForMinGW\bin\idc.exe
