"Fossies" - the Fresh Open Source Software Archive

As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard) with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file. See also the latest Fossies "Diffs" side-by-side code changes report for "README.TESTING": 2.3.2_vs_2.3.3.

    3 To run the tests suite, all you need is (add the cmake options if you need any
    4 or if the default libs and include paths are not the default) :
    6 In a sub directory:
    7 $ mkdir bld
    8 $ cd bld
    9 $ cmake -DBUILD_TEST=1 ..
   10 $ make
   11 $ ctest .
   13 Or if you like to build in the source tree:
   14 $ cmake -DBUILD_TEST=1 .
   15 $ make
   16 $ ctest .
   18 Add "-DCMAKE_BUILD_TYPE=DEBUG" if you like to have a debug version.
   20 If you like to run the tests against a installed GD library, set the following
   21 environment variables:
   23 export CMAKE_INCLUDE_PATH=/path/to/the/gd/include
   24 export CMAKE_LIBRARY_PATH=/path/to/the/gd/lib
   26 then call cmake using:
   28 $ cmake -DUSE_EXT_GD=1 -DBUILD_TEST=1
   29 $ make
   30 and finally:
   32 $ ctest .
   34 I will certainly add a nice CMake option to give prefix later.
   36 What to do if tests fail on your platform and you use the last GD release?
   37 either from your favorite distributions or from https://www.libgd.org or git?
   39 If you use a packaged version of the GD Library (installed from RPM, deb or
   40 ports, gentoo packages or any other packages format or distribution), please try
   41 to run the tests using the source releases available at:
   43 https://github.com/libgd/libgd/releases
   45 If the tests fail using our source release, please report a bug here:
   47 https://github.com/libgd/libgd/issues
   49 You can attach the two files available in:
   51 ./Testing/Temporary
   53 Later versions will have an automatic post mode.
   55 If the tests do not run successfully, please report a bug to the maintainer of the
   56 packages (Debian, BSD, Ubuntu or whoever is responsible for the packages).
   58 Reasons of failures:
   59 Exception: SegFault: self explaining
   60 Failed               test failed, check the log to know where
   61 timeout              the default timeout is 5 seconds. Some test may
   62                      have infinite loops when compiled against old versions
   63                      of the GD library (esp. 2.0.33 or earlier)
   65 Some features rely on floating point arithmetic and results may vary from
   66 one architecture to another.
   67 Examples:
   68 On i686, gdimagerotate/bug00067 will fail. The result is still visually
   69 acceptable but i686 default arithmetic mode will generate different results.
   70 Adding "-msse -mfpmath=sse" to CFLAGS will solve this difference.
   71 On s390, ppc64, and aarch64, gdimagecopyresampled/bug00201 will fail.
   72 The result is still visually acceptable.
   73 Adding "-ffp-contract=off" to CFLAGS will solve this difference.
