I've created 3 files: swap.h and swap.c then make static library from it
Code:
Then I write 2 program to test this library: test_swap.c and test_swap.cpp
I compile

What's wrong with this in C++? And how can I make a library that can work both for any C and C++ program?

I am trying to use the QT4 frontend of poppler library in my application so I need to compile the library.In its main directory ./configure can be run but I got
Code:
checking which font configuration to use... fontconfig
checking for FONTCONFIG... no
configure: error: Package requirements (fontconfig >= 2.0.0) were not met:
No package 'fontconfig' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables FONTCONFIG_CFLAGS
and FONTCONFIG_LIBS to avoid the need to call pkg-config.See the pkg-config man page for more details.
I have fontconfig installed (ubuntu):
2.8.0-2.1ubuntu3 (fontconfig)
However I have no idea where those flags are and what to set them to.
I've started programming in c recently . following are the details about scene:
* vim is editor and program is compiled in gcc whenever a program involving math function appears it gives error i.though math.h is included in header file compiler complains about it it gives error of unrecognized function that math function like sqrt, etc question is how to connect math.h to a program.
I have been using gcc to compile C programs.
I want to know what exactly is the meaning of Compiling a C program.
I checked
cc -S prog.c
will give an .S file and if you analyze the hexdump I saw some assembly instructions.
So what does the compiler do which is not required in case of interpreted languages?
it possible to access main program function from dynamicallyinked library in c language?For example:main.c:
Code:
#include<stdio.h>
void func()
[code]...
I'd like to get path of one library to link it dynamically in my program. Probobly the best way would be to add macro to my configure.ac file.

I have searched for dependency information and used apt-get to add anything I can find. How can I identify and find the dependencies for source? I have checked the source documentation though typically does not list required packages. My other question is how to check the path used to locate the libraries? Given the length of the missing library list, I think the problem may be configuring make.
I'm interested in modding an open-source turn based game called Advanced Strategic Command or ASC, but to do that I need bunch of libraries. Installing those libraries is very easy in linux, I know but the thing is I'm working with windows in which the building of the libraries is a bit more complex, as you probably know. One of those libraries is the ligsigc++, I'm using VC++ but haven't been successful in building the libsigc++ in VC++. I considered making my life easier with Cygwin (a unix shell for windows) and simply executing ./Configure, Make. I's worked like a charm and the library dll it produced is named cygsigc-2.0-0.dll which made me wonder is compiling a library in cygwin to be linked with VC++ perfectly ok? That is is there any difference in compiling in cygwin and VC++?
