HakuNeko logoJust yesterday I’ve showed you how to modify and compile the [HakuNeko] Manga Ripper so it can work on FreeBSD 10 UNIX, [see here] for some background info. I also mentioned that I couldn’t get it to build on CentOS 6 Linux, something I chose to investigate today. After flying blind for a while trying to fix include paths and other things, I finally got to the core of the problem, which lies in HakuNekos’ src/CurlRequest.cpp, where the code calls CURLOPT_ACCEPT_ENCODING from cURLs typecheck-gcc.h. This is critical stuff, as [cURL] is the software library needed for actually connecting to websites and downloading the image files of Manga/Comics.

It turns out that CURLOPT_ACCEPT_ENCODING wasn’t always called that. With cURL version 7.21.6, it was renamed to that from the former CURLOPT_ENCODING as you can read [here]. And well, CentOS 6 ships with cURL 7.19.7…

When running $ ./configure && make from the unpacked HakuNeko source tree without fixing anything, you’ll run into this problem:

g++ -c -Wall -O2 -I/usr/lib64/wx/include/gtk2-unicode-release-2.8 -I/usr/include/wx-2.8 -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D__WXGTK__ -pthread -o obj/CurlRequest.cpp.o src/CurlRequest.cpp
src/CurlRequest.cpp: In member function ‘void CurlRequest::SetCompression(wxString)’:
src/CurlRequest.cpp:122: error: ‘CURLOPT_ACCEPT_ENCODING’ was not declared in this scope
make: *** [obj/CurlRequest.cpp.o] Error 1

So you’ll have to fix the call in src/CurlRequest.cpp! Look for this part:

  1. void CurlRequest::SetCompression(wxString Compression)
  2. {
  3.     if(curl)
  4.     {
  5.         curl_easy_setopt(curl, CURLOPT_ACCEPT_ENCODING, (const char*)Compression.mb_str(wxConvUTF8));
  6.         //curl_easy_setopt(curl, CURLOPT_ACCEPT_ENCODING, (const char*)memcpy(new wxByte[Compression.Len()], Compression.mb_str(wxConvUTF8).data(), Compression.Len()));
  7.     }
  8. }

Change CURLOPT_ACCEPT_ENCODING to CURLOPT_ENCODING. The rest can stay the same, as the name is all that has really changed here. It’s functionally identical as far as I can tell. So it should look like this:

  1. void CurlRequest::SetCompression(wxString Compression)
  2. {
  3.     if(curl)
  4.     {
  5.         curl_easy_setopt(curl, CURLOPT_ENCODING, (const char*)Compression.mb_str(wxConvUTF8));
  6.         //curl_easy_setopt(curl, CURLOPT_ACCEPT_ENCODING, (const char*)memcpy(new wxByte[Compression.Len()], Compression.mb_str(wxConvUTF8).data(), Compression.Len()));
  7.     }
  8. }

Save the file, go back to the main source tree and you can do:

  • $ ./configure && make
  • # make install

And done! Works like a charm:

And now, for your convenience I fixed up the Makefile and rpm/SPECS/specfile.spec a little bit to build proper rpm packages as well. I can provide them for CentOS 6.x Linux in both 32-bit as well as 64-bit x86 flavors:

You need to unzip these first, because I was too lazy to allow the rpm file type in my blogging software.

The naked rpms have also been submitted to the HakuNeko developers as a comment to their [More Linux Packages] support ticket which you’re supposed to use for that purpose, so you can get them from there as well. Not sure if the developers will add the files to the projects’ official downloads.

This build of HakuNeko has been linked against the wxWidgets 2.8.12 GUI libraries, which come from the official CentOS 6.7 package repositories. So you’ll need to install wxGTK to be able to use the white kitty:

  • # yum install wxGTK

After that you can install the .rpm package of your choice. For a 64-bit system for instance, enter the folder where the hakuneko_1.3.12_el6_x86_64.rpm file is, run # yum localinstall ./hakuneko_1.3.12_el6_x86_64.rpm and confirm the installation.

Now it’s time to have fun using HakoNeko on your Enterprise Linux system! Totally what RedHat intended you to use it for! ;) :roll:
