With 2.4.14: $ /usr/lib64/libgphoto2/print-camera-list udev-rules version 136 group plugdev|wc -l 1306 With 2.5.2: $ /usr/lib64/libgphoto2/print-camera-list udev-rules version 136 group plugdev|wc -l 383 /lib/udev/rules.d/70-libgphoto2.rules has much less rules after update.
Rebuilding with libxml2 enabled solved problem: Number of supported cameras: 1711 So we have 2 bugs here: 1) ebuild has missing libxml2 RDEPEND 2) Build system fails to detect libxml2 headers, because it is not using pkg-config and is looking for /usr/include/libxml/parser.h. Gentoo has /usr/include/libxml2/libxml/parser.h I used symlink as tmp workaround: pushd /usr/include/ ln -s libxml2/libxml libxml
Other bugs and suggestion for 2.5.2 ebuild: 1) --without-hal option was removed, even 2.4.14 does not have it 2) --with-drivers= was renamed to --with-camlibs= 3) Use udev 175 mode for print-camera-list isntead of 136, it was added in 2.4.14, minimal version of udev in portage tree now is 204. 4) IUSE_CAMERAS needs updating: add pentax, remove sipix_blink and template.
Nice investigations of you (In reply to Nikoli from comment #3) > Rebuilding with libxml2 enabled solved problem: > Number of supported cameras: 1711 > > So we have 2 bugs here: > 1) ebuild has missing libxml2 RDEPEND > 2) Build system fails to detect libxml2 headers, because it is not using > pkg-config and is looking for /usr/include/libxml/parser.h. Gentoo has > /usr/include/libxml2/libxml/parser.h The proper way in my opinion is to patch it with the pkg-config and try to land it upstream :-) instead of creating a symlink > I used symlink as tmp workaround: > pushd /usr/include/ > ln -s libxml2/libxml libxml
Sure, i did so only for quick checking if it will solve my problem with missing cameras.
http://sourceforge.net/p/gphoto/bugs/953/ This looks to be the upstream report about this... but I wonder if its attached patch is correct :| Also got surprised --enable-option-checking needs to be explicitly added to get the warnings about the missing configure options :O Thanks for the report and finding the issues, will try to take care of this when I have time (if nobody beats me), but would like a bit of help with the libxml2 detection issue :/
the current configuration indeed reports ... checking for xmlFirstElementChild in -lxml2... yes checking libxml/parser.h usability... no checking libxml/parser.h presence... no checking for libxml/parser.h... no ... there an improvement upstream available: http://sourceforge.net/p/gphoto/code/14416/tree/trunk/libgphoto2/configure.ac?diff=50c8ee315fcbc9098bbba8e5:14408&diformat=regular
with this patch I gain the libxml detection checking for libxml-2.0 to use... autodetect checking for LIBXML2... yes checking libxml/parser.h usability... yes checking libxml/parser.h presence... yes checking for libxml/parser.h... yes checking for function xmlFirstElementChild in libxml-2.0... yes checking libxml-2.0 library flags... "-lxml2 " checking libxml-2.0 cpp flags... "-I/usr/include/libxml2 " checking for dirent.h that defines DIR... yes checking for library containing opendir... none required and libxml2 support libxml-2.0: yes however the compilation fails with ../gphoto2/gphoto2-file.h:129:5: note: expected 'char *' but argument is of type 'unsigned char *' ptp2/ptp.c:30:28: fatal error: libxml/parser.h: No such file or directory compilation terminated. make[3]: *** [ptp2/ptp.lo] Error 1 make[3]: *** Waiting for unfinished jobs.... so I assume this second patch from upstream is also needed http://sourceforge.net/p/gphoto/code/14415/tree//trunk/libgphoto2/camlibs/ptp2/Makefile-files?diff=50c8ee315fcbc9098bbba8e5:14414

With this both patches appied libxml2 support seems to be properly detected and built

Created attachment 363822 [details, diff] r14415 Evgeny, thanks for finding upstream changes, but you used wrong way for extracting them. Both attached patches are from same commit: http://sourceforge.net/p/gphoto/code/14415/ Correct way to create patches from svn commits: svn diff -c 14415 svn://svn.code.sf.net/p/gphoto/code/trunk > libgphoto2-2.5.2-detect-libxml2.patch I think it is better to merge both patches into one, no need for having 2.
