类似'QFileDialog' has not been declared 这样的编译不过,可以先试着 加一下头文件,如下: #include <QFileDialog> 类似的还有 error: variable 'QPainter painter' has initializer but incomplete type QPainter painter(this); ^ 也是需要加 #include <QPainter> 刚接触,很多内容都比较生疏。
typedef long double float64; ti中有dmctype.h和DSP281x_Device.h两个头文件均定义了上述数据类型,但是不管我用那个头文件参与编译,编译均会出现warning: typedef name has already been declared (with same type) 的警告,查找原因发现是IQmathLib.h中的long数据类型与dmctype.h或DSP281x_Device.h中的long重...
"My dog has no type." "How does he smell?" "Awful!"This article originally was called "Expressions with no types" but that was a misleading title. This article is really about expressions which have a "quantum superposition" of several types: that's to say, the expression ...
Apparently, the variable iyr has not been declared and the code contains a statement "IMPLICIT NONE" or the compiler options instruct the compiler to complain about any variables that are not explicitly declared. The solution is to properly declare it: integer :: iyr for instance i...

There're two definitions of typedef struct u8log_struct u8log_t; in u8x8.h file line 412 (previously defined at the line 392). During compilation I've got an error typedef name has already been declared (with same type). The development ...

如果在使用Thrift时,编译遇到类似“TTransport.h:107: error: 'uint32_t' does not name a type”的错误,只需要在Thrift.h文件中增加一行:#include 。 Thrift.h文件位于make install后的include目录下,如果不知道在哪,可以使用find命令查找。
