Problem in compilation using cygwin

[deswal]

I am using cygwin and when i compile program hello.cc
by command gcc hello.cc -o hello
it shows installation problem,cannot exec ‘cc’plus’:No such file or directory

but when i execute program with command ./hello.exe
it shows output

how should i remove this problem plz tell me.

It seems that you don't have the C++ compiler installed in your Cygwin environment. To check, try this: g++ hello.cc -o hello

That will invoke the C++ compiler if it exists. If not, then you will get a file/command not found error.

Thanks Sir,
Hello.cc is compiled properly with command
g++ hello.cc -o hello

Now i am to work on sense simulator using cygwin,for this i put sense-3.0.3 in
cygwin/usr/local/sense-3.0.3

after building of simulator with followin commands
In order to build the simulator:
cd sense-3.0.3/code
make

To build the examples:
make test

To build the utilities that will analysis the state of the SSR or SHR simulation:
cd analyzer/src
make

Then cxx file is made in sense-3.0.3/code/bin directory
and exe files are made of built-in program in sense-3.0.3/code/examples/sense directory

if i compile sim_80211.cc program by using following command
g++ sim_80211.cc -o sim_80211

it shows following errors
sim_80211.cc :14:2: error invalid Preprocessing directive #cxxdef
In file include from ../..common/cost.h:13
in file include from ../..common/sense.h:46

but when i execute sim_80211's exe file by command
./sim_80211.exe
it shows complete result

how this problem can be removed.

[Rubberman]

Usually, you would place #ifndef/#endif statements around the offending #cxxdef statement, such as:

#ifndef __CYGWIN__
#cxxdef ...whatever...
#endif /* __CYGWIN__ */

That will keep the compiler from seeing the #cxxdef line, and thus give no error or warning. Since the compiler apparently completed, my guess is that the preprocessor error was ignored in this case. Whether or not that may cause a problem is unknown since I don't have the offending source code to analyze.

[deswal]

Sorry Sir, but this command not working because compiler shows error in other included header files like
../../common/priority_q.h
error: no argument to 'strcat'
../../common/cost.h
error: expected initializer before '<' token
../../app/cbr.h
error: 'component' does not name a type

it seems that their is no linking between files.

It is given :-
To compile the program, enter:

* ../../bin/cxx sim_routing.cc
g++ -Wall -o sim_routing sim_routing.cxx

* To run the simulation, simply type in:

sim_routing [StopTime] [NumNodes] [MaxX] [NumSourceNodes] [ActivePercent] [PacketSize] [Interval]

[deswal]

I had fix these errors by using following commands
../../bin/cxx sim_routing.cc
g++ -Wall -o sim_routing sim_routing.cxx

but now it shows following errors
../../common/priority_q.h/ : in member function bool "guarded Queue"<ITEM> ::validate<const char*>;
error : their is no 'strcat' that depends on template parameter so declaration of strcat must be available
