I'm trying to extend someone's work, but without success in including his header files appropriately. Namely, I compile the code by using


g++ -o myprog $(pkg-config --cflags --libs libgraph...

The code:


void myFunct(Agraph_t * g, GVC_t * gvc) {
FILE *fp;
Agnode_t *v;
Agedge_t *e;

gvc=gvContext();

Thanks for the message. Bellow is the struct content:

Using


void myFunct( Agraph_t * g) {

Since my coding work is based more on C++, I'm unclear about how to make changes take effect after function call in C.
Namely, I have the following struct declartion and function call in C

Thanks for the message. Well, I suppose there is a workaround. Doing the type change might be costly.

With the following code, I get errors after compiling:
[code]
#ifdef __cplusplus
extern "C"
#endif

void displayVector(const VecType& myVec);
[\code]

Is there a...

Given the file content as defined above, what is the exact sequence of commands I should use to make it work?


gcc -c source.c
gcc -c source.cpp // well, same file name
gcc source.o source.o -o...

Done that! Now, it complains about the actual function:

/tmp/cccMKk1q.o: In function `main':

Thanks!
Could you provide me with the minimal working example, i.e. the content of .h, .cpp and .c files that I might use as the development base.
I tried C wrapping of C++ code example, but get...

I understand that.

But, hauzer suggest that by importing certain library in C I might utilize my C++ code.
Anyway, what is your suggestion?

Thanks for the message.

What external library should I use to facilitate the work?
I suppose the std:: preceding vector would fit withing the library environment.

I'm required to "transfer" my c++ implementation as an addition to already existing c code. The main problem are the structures that I use in c++, and that are not recognized by c. For instance, the...

I'm using stxxl library, and recently I noticed that compile time is significantly increased. Therefore, I tried to make use of precompiled header files.

Thanks for your answers. I understand your point, but please note that I do not have any inappropriate intentions. Given the time constraint, it was urgent to get proposals, which usually are...

Actually, I'm working with external memory computations; that is the main reason small improvements could be of great benefit. I do not use a profiler (dont know how to use it). Do you think using...

I wonder whether there is a faster way (faster then the obvious one a=a*a) to square the content of a vector of floats. I remember that bit shifting could be used somehow, but I'm not sure whether...

Can you help me somehow?
Thanks
