Re: pp missing module error

I guess that the problem is caused by GD.pm's nature as "just" an interface to the GD library. This library comes with Strawberry Perl. I don't have a Windows system available right now, but by looking at sources from an old project I guess that you need to add the library explicitly:

pp ... --link=libgd-3__.dll
[download]

Verify the name of the DLL, it should be located in Strawberry's c/bin directory.

Edited: it's --link, not --lib. And yes, that's two underscores.

I've altered the pp command as follows: `pp -v --output myprogram.exe --link=C:\Strawberry\c\bin\libgd-3__.dll +--link=C:\Strawberry\perl\vendor\lib\auto\Class\Load\XS\XS.xs.dll myp +rogram.pl` [download] Still getting the same error. I REALLY don't want to have to install perl and libraries on a target computer to run this - people just want an exe to run ...	[reply] [d/l]

Ok, I got hold of two Windows systems... one to build the executable, the other with no Strawberry (such things exist!) to run it. Here's the `pp` invocation in my `.bat` file: `pp --verbose ^ --link=libgd-3__.dll ^ --link=libbz2-1__.dll ^ --link=libgraphite2__.dll ^ --link=libharfbuzz-0__.dll ^ --link=libfreetype-6__.dll ^ --link=libiconv-2__.dll ^ --link=libjpeg-9__.dll ^ --link=liblzma-5__.dll ^ --link=libpng16-16__.dll ^ --link=libtiff-5__.dll ^ --link=libXpm__.dll ^ --link=zlib1__.dll ^ --module=GD ^ --output=gdpacked.exe ^ pack_gd.pl` [download] The program `pack_gd.pl` is just the synopsis from GD on metacpan. Running `pp` produces no error, and running the executable prints a PNG image. So when you run it, remember to redirect the output to a `.png` file. In my first reply, I mixed up some dashes with underscores and missed a few dependencies. Sorry.	[reply] [d/l]

Thanks very much - this worked - explicitly linking in the list of libraries. I did also try ppsimple - however the install of Proc::Background failed test 47 and did not install - after installing SomeUtils and AllUtils. But, I digress. My sincere thanks to everyone who chimed in to help - and get this off zero for me - you are appreciated :)	[reply]

Oh well... The GD library has a few dependencies by itself. Here's a list of suspects: `libfreetype_6__.dll` `libiconv_2__.dll` `libjpeg_9__.dll` `libpng16_16__.dll` `libtiff_5__.dll` `libXpm__.dll` `zlib1__.dll` That's just from the strings in `libgd-3__.dll`, I can't say whether the list is comprehensive. I'll probably get some time to experiment on my Windows box in a few days. As an aside: As far as I can say, You don't need to provide the absolute path to the libraries. `pp` should find them as they're on `pp`'s path.	[reply]
