I'm trying to add the Chilkat C/C++ libraries into a project in CodeBlocks (32-bit, version 12.11) for Windows 7.
So I went to http://www.chilkatsoft.com/downloads_mingw.asp, and downloaded the 32-bit MinGW library.
Then in CodeBlocks I did:
Settings>Compiler>Linker Settings>Add>C:\chilkat-9.5.0-mingw32\libchilkat-9.5.0.a
Settings>Compiler>Search Directories>Compiler>Add>C:\chilkat-9.5.0-mingw32\include
Settings>Compiler>Search Directories>Linker>Add>C:\chilkat-9.5.0-mingw32
Project>Build Options...>Project Root>Linker Settings>Add>C:\chilkat-9.5.0-mingw32\libchilkat-9.5.0.a
Project>Build Options...>Project Root>Search Directory>Compiler>Add>C:\chilkat-9.5.0-mingw32\include
Project>Build Options...>Project Root>Search Directory>Linker>Add>C:\chilkat-9.5.0-mingw32
Then I set my compiler to GNU GCC Compiler.
Finally, I encounter these two issues:
When I do #include<...> and press Ctrl+Space inside the brackets, there are no suggestions for anything related to the Chilkat library. See first code block below for full code (pretty simple).
While the program builds successfully with CkMailMan.h included, it breaks when I instantiate CkMailMan, with the errors shown in the second code block below.
I suspect it has to do with the library extension being ".a," which is for Linux. But I get the same problem when I do a Visual Basic version of this library (extensions .dll) and use the Microsoft Visual C++ 2010 compiler. Any ideas?
Code:
#include <iostream>
#include <CkMailMan.h>
using namespace std;
CkMailMan mailman;
int main()
{
cout << "Hello world!" << endl;
return 0;
}

Turns out I needed to switch to the visual Studio C++ compiler and download the library in that compiler's format. I was right about not being able to use '.a' extension libraries.

I have got all required lib files, Then Why it is giving this error ?
I am using this tutorial to create a cross-compiler.
I followed the gcc cross-compiler tutorial and went to the porting newlib. Everything worked fine till I tried compiling it by issuing
make all install
when I got the following error:
WARNING: `makeinfo' is missing on your system. You should only need it if
you modified a `.texi' or `.texinfo' file, or any other file
indirectly affecting the aspect of the manual. The spurious
call might also be the consequence of using a buggy `make' (AIX,
DU, IRIX). You might want to install the `Texinfo' package or
the `GNU make' package. Grab either from any GNU archive site.
and the compilation stops.
I am using Ubuntu 11.10.
I have tried:
using different gcc, binutils and newlib versions (about 5 different combinations)
installing Texinfo
correcting makeinfo path
My cross-compiler works perfectly without the newlib just that it of course cannot include the libraries.
Even if you have makeinfo installed, it may not recognize newer versions. The following patch works. Copy below and save as "configure.patch", save it where the configure script is, then type "patch -p1 < configure.patch".

I was trying to install 6809 GDB and got this error. I fixed by going into Makefile and changing

to
MAKEINFO = makeinfo

After removing the entire directory and redownloading, the makefile was all correct (no missing directory) and make and make install completed fully. So perhaps the modifications to the makefile weren't needed and I just needed to have bison, flex, and makeinfo installed.

Is there another library that I need to link to?
Adding -lresolv solved this for me.

Those are link errors. You could do a compile only (notice that I added the -c flag):
avr-gcc -c -mmcu=atmega88 blinky.c
You would then have to link that with your other objects to create a binary.
Alternately, you could provide all the source files in a single command line and the compiler will compile and link them:
avr-gcc -mmcu=atmega88 blinky.c print.c usb_debug_only.c
