[Dev-C++] Undefined reference to wctype()...

[Siva C. <siv...@ya...>]

Hello all,

I am trying to compile and test greta. It compiles
fine.
I downloaded a sample program and am trying to compile
it.
Here again it compiles fine but the linker gives two
undefined reference errors:

1. undefined reference to 'wctype'
2. undefined reference to 'btowc'

Do I have to link some other libraries while I
compile?
If yes, which ones?

TIA

Siva Chandra.

yes, you need to link against 'libmsvcr70.a', just adding -lmsvcr70 to
the linker flags schould be also ok.
Just a small hint:
If you have some undefined references, this is mostly because you have
forgotten to link against something. You can solve this by grepping
through your lib directy. For Example you want to find in which file the
btowc function resides:

1. Open a command prompt (Under winnt-systems Start->run->cmd)
2. Change to your lib dirrectory (Its in your Dev-Cpp directory)
3. grep after your string, in our example you have to do 'grep btowc *'
(If you don't have grep you can obtain it from
http://gnuwin32.sourceforge.net/packages/grep.htm)
Then all files which contains this string are listed.

This method doesn't help all the time, but in most cases you'll find a
~ 	appropriate lib to link against.

Hello Tim,

Firstly, thanks a lot for the tip.

I use the search tool to search for files containing
the text "whatever". In this case I got a result of 33
*.a files including the libgreta.a file which uses
wctype().
So I thought, instead of trying out each of these libs
I should be asking someone and may be save time. But
alas I could'nt and I tried out each of those files
and found that linking with libmsvcp60.a solves the
problem!!
