Re: Net::LibIDN in Windows, is it possible?

And if I have to install it, will I have to install it on every Windows computer that runs a copy of my code?

If you build against a static libidn library, then the libidn functionality will be built into the Net::LibIDN binaries, and you won't have to distribute anything other than your build of Net::LibIDN. But if you build against a shared libidn library (dll) then you'll have to distribute the dll as well as your build of Net::LibIDN.

I find that libidn-1.12 builds fine as a static library (didn't test a shared build) using MinGW in the MSYS shell. Just run ./configure --disable-shared --enable-static LDFLAGS=-L/usr/local/lib CPPFLAGS=-I/usr/local/include followed by make && make check then make install. Note that libiconv, which can be built using the same mantra, is also required.

Here's a diff showing the hack I made to the Makefile.PL in order to build Net::LibIDN-0.11:

Unfortunately the tests fail with "Free to wrong pool..." errors, perhaps the result of bad practices used in the XS file. I'll see if I can patch the XS file so that the tests pass - and I'll post again to this thread when (if) I succeed.

Cheers,
Rob

See Re: [Win32] "Free to wrong pool ..." error. Not necessarily the right way to correct it.

I know this is an old post, but I need help getting Net::LibIDN installed in Windows. I successfully built libidn-1.12 as a static library using MinGW/MSYS and the instructions from syphilis, but now I get the following output when I create the make file... $ perl Makefile.PL Found LibIDN, with TLD checking support Checking if your kit is complete...

Stop. [download] I feel like I'm so close, or that I'm missing something obvious. Any ideas? UPDATE: I've got Visual Studio 2005 installed, and if I try building with nmake, the build actually runs for a little until I get this error: `fatal error C1083: Cannot open include file: 'stdint.h': No such file +or directory` [download] Thanks, Rob	[reply] [d/l] [select]
