See : http://koji.fedoraproject.org/koji/taskinfo?taskID=5490492 Build seems ok (despite a lot of warnings) Some test succeed, so extension seems mostly ok. Other failed tests need investigation. I will try to work on this, but, as I'm not a perl monger, help welcome.
From my test results, I think we can ignore the test results for now. I have generated the output images (under fedora 17) - with gd 2.0.35 - with gd 2.1.0 Results are "visibly" the same. Digging (ex on test 4, the smaller image) $ ll test.out.4*png -rw-r--r--. 1 extras remi 290 11 juin 14:42 test.out.4.gd20.png -rw-r--r--. 1 extras remi 290 11 juin 14:46 test.out.4.gd21.png -rw-r--r--. 1 extras remi 269 26 févr. 11:57 test.out.4.png $ diff test.out.4.png test.out.4.gd20.png Binary files test.out.4.png and test.out.4.gd20.png differ $ diff test.out.4.gd20.png test.out.4.gd21.png (no diff) $ pngcheck -vtc test.out.4.png test.out.4.gd20.png test.out.4.gd21.png File: test.out.4.png (269 bytes) chunk IHDR at offset 0x0000c, length 13 100 x 50 image, 2-bit palette, non-interlaced chunk PLTE at offset 0x00025, length 12: 4 palette entries chunk IDAT at offset 0x0003d, length 188 zlib: deflated, 32K window, default compression chunk IEND at offset 0x00105, length 0 No errors detected in test.out.4.png (4 chunks, 78.5% compression).

No errors were detected in 3 of the 3 files tested. To resume, diff are. - new "PHYS" chunk missing in ref images - zlib deflated mode 32k vs 2k
I have update to 2.49 and skip failed tests. For now, until a new upstream version is available since acceptable. So, our build will mostly rely on test 1, 11 and 12, and packager eyes ;) Package: perl-GD-2.49-1.fc20 Tag: f20 Status: complete Built by: remi
Changes seems really related to GD 2.1.0 feature From libgd-2.1.0/src/gd_png.c #ifdef PNG_pHYs_SUPPORTED /* 2.1.0: specify the resolution */ png_set_pHYs(png_ptr, info_ptr, DPI2DPM(im->res_x), DPI2DPM(im->res_y), PNG_RESOLUTION_METER); #endif And 32k windows is commented. /* png_set_compression_window_bits(png_ptr, 15); */
