Hi Oliver, can you wait until Monday? I'm busy packing my stuff. Moving tomorrow. Regards, Christian On Sat, Feb 27, 2010 at 9:29 AM, Olivier Tournaire <olitour@gmail.com> wrote:
Hi all,
I have just checkout gil-contributions svn repo (http://code.google.com/p/gil-contributions/) in order to test new_io in which I am really interested. Thank you for this very usefull job! I have however some remarks and questions about some compilation issues.
0) The code seems to have been written and tested on Windows. Am I right (see my remarks thereafter)? For ex., why do you use "\\" in paths (paths.hpp) and not "/"? 1) Which Boost version is required? I first tried with 1.40, but it did not work because of missing accessors in boost::gil::variant (index() and bits()). Did they appear in 1.41 or 1.42? With 1.42, this issue is solved. 2) While compiling tests, I ran into some issues. I am running the code on an Ubuntu 9.10, with g++-4.3.4. I was able to fix some of them, but others are still problematic: 2.1) For each test, I have to add at the beginning the 2 following lines:
#define BOOST_TEST_DYN_LINK #define BOOST_TEST_MODULE my application tests
It probably comes from my little knowledge of boost unit_test_framework. Could you explain?
2.2) For each test, the compiler gave the following error:
/usr/local/include/boost/gil/extension/io_new/detail/dynamic_io_new.hpp:75: error: there are no arguments to ‘io_error’ that depend on a template parameter, so a declaration of ‘io_error’ must be available
I simply add in [...]/detail/dynamic_io_new.hpp an unclude directive at the beginning of the file : #include <boost/gil/extension/io/io_error.hpp>. Still do not understand how it can work wihtout this ...
2.3) I had a similar error with [...]/formats/bmp/read.hpp:
/usr/local/include/boost/gil/extension/io_new/formats/bmp/read.hpp:833: error: there are no arguments to ‘get_info’ that depend on a template parameter, so a declaration of ‘get_info’ must be available
I simply changed line 833 from get_info() to parent_t::get_info(). Now works.
2.4) Some typename are missing (still do not know how visual can infer types ...): - [...]/formats/jpeg/read.hpp, line 336: typename Image::view_t - [...]/formats/bmp/is_allowed.hpp, line 73: typename View::value_type - [...]/formats/pnm/read.hpp, line 419: typename Image::view_t Everything works with these changes.
2.5) png_read_test failed. Obviously, this is a portability issue. PNG filenames for testing are uppercase, while they are lowercase in the test code. I think that is also missing in the code the path to png files. For example, in basic_format_test, instead of
test_file< gray1_image_t >( "basn0g01.png" ); it soulhd be: test_file< gray1_image_t >( png_in + "BASN0G01.PNG" ); I did not rename all files, so I am unable to try the test.
2.6) Some tests fail to compile or link. Here are the errors:
- all_formats_test.cpp: In file included from /usr/include/png.h:481, from /usr/local/include/boost/gil/extension/io_new/png_tags.hpp:23, from /usr/local/include/boost/gil/extension/io_new/png_read.hpp:22, from /usr/local/include/boost/gil/extension/io_new/png_all.hpp:22, from /home/olivier/work/dev/lib/gil-contributions-read-only/gil_2/libs/gil/io_new/test/all_formats_test.cpp:7: /usr/include/pngconf.h:335: error: expected constructor, destructor, or type conversion before ‘.’ token /usr/include/pngconf.h:336: error: ‘__dont__’ does not name a type

Apart png_read_test and its case sensitive problem, all compiled and linked tests run successfully. This is a really good new! However, could you please help regarding the issues above? Please note that if you are intersted in a Linux developper/tester for gil, I am wiling to do some jobs ...
Best regards,
Olivier
